Bed Bug Infestation in Denver (What to Do)

Last updated: March 18, 2026

By James — Founder of Pest Control Pricing

Denver's bed bug problem is growing. The city has climbed into the top 15 to 20 most bed bug-infested cities in the United States according to annual rankings published by major pest control companies, and complaints to Denver Environmental Health have increased steadily over the past several years. The Denver metro area's combination of a large and growing rental market, a booming tourism and convention industry, a constant flow of ski travelers passing through hotels and short-term rentals, and rapid population growth from in-migration has created conditions that allow bed bugs to spread efficiently across the metro. If you are dealing with a bed bug infestation in Denver, understanding the local landscape, your rights, and the treatment options that work best at altitude and in Colorado's dry climate will help you respond effectively and get the problem resolved.

One common misconception is that Denver's high altitude (5,280 feet) or cold, dry winters make the city less hospitable to bed bugs. This is not the case. Bed bugs are indoor pests. They live in mattresses, bed frames, baseboards, and upholstered furniture inside climate-controlled homes and apartments. Outdoor elevation, temperature, and humidity have no effect on bed bug populations because they never live outdoors. A bed bug in a Capitol Hill apartment at 5,280 feet behaves identically to one in a Miami condo at sea level. Denver's bed bug problem is real, growing, and requires the same professional treatment approach used in any other major city.

This guide covers why bed bug infestations are increasing in Denver, how to identify an infestation (including how to distinguish bed bugs from bat bugs, which are common in Colorado), your rights as a tenant under Colorado law, treatment options and their effectiveness in Denver's dry climate, what treatment costs, how to choose a qualified exterminator, and how to prevent future infestations.

Denver's Bed Bug Problem

The scale of Denver's bed bug problem has grown considerably over the past decade. Denver consistently appears in the top 15 to 20 cities on annual bed bug rankings compiled by Orkin and Terminix, and the metro area has moved up in those rankings in recent years as the city's population has grown and housing density has increased. Bed bug complaints filed with Denver Environmental Health have trended upward, with multi-unit apartment buildings generating the highest volume of reports. The problem is not confined to any single neighborhood or income level. Bed bugs have been reported in luxury apartments in LoDo, in student housing near the University of Denver and Auraria Campus, in vintage apartments throughout Capitol Hill and Cheesman Park, in newer construction in RiNo and the Highlands, and in single-family homes across the suburbs.

What makes Denver's situation notable is the speed at which the problem has intensified. Between 2015 and 2025, the Denver metro added approximately 300,000 new residents, making it one of the fastest-growing metros in the country. That population growth brought new housing construction, but it also increased density in existing neighborhoods, drove up demand for rental housing, and created the kind of population churn (people moving in, moving between apartments, and moving out) that accelerates bed bug dispersal. Unlike cities with long-established bed bug problems like Chicago or New York, Denver's problem is still building, which means the window for proactive prevention and early intervention is particularly important for Denver residents.

The Denver metro's unique position as a gateway to Colorado's ski resorts also plays a role. During ski season (November through April), hundreds of thousands of visitors flow through Denver International Airport and stay in hotels, Airbnbs, and vacation rentals throughout the metro before heading to the mountains. This constant rotation of travelers creates ongoing exposure risk for the hotels, motels, and short-term rentals they occupy, and for the permanent residents who live in or near those properties. Bed bugs travel in luggage, and a single infested guest can introduce bed bugs into a previously clean hotel room or rental unit.

Why Bed Bug Infestations Are Increasing in Denver

Several factors specific to Denver and the Front Range contribute to the city's growing bed bug problem. Understanding these factors helps explain why infestations keep rising and why certain neighborhoods are more affected than others.

Dense Rental Housing in Core Neighborhoods

Capitol Hill is the densest residential neighborhood in Denver, with a mix of vintage apartment buildings (many dating to the early 1900s), newer mid-rise construction, and converted single-family homes divided into multiple units. This density is ideal for bed bug spread. When one unit in a multi-unit building is infested, bed bugs can migrate to adjacent units through shared walls, along plumbing and electrical conduits, and through cracks in older construction. Capitol Hill alone generates a disproportionate share of Denver's bed bug complaints, driven by the combination of high density, older buildings with more entry points between units, and significant population turnover as young professionals and students cycle through apartments.

Uptown (also called North Capitol Hill) shares many of these characteristics, with a mix of older walk-ups and newer apartment complexes. RiNo (River North Art District) and Five Points have seen rapid densification as new apartment buildings have filled in formerly industrial and low-density areas. Baker, on the south side of downtown, has a similar mix of older and newer rental housing. Each of these neighborhoods combines the density, rental population, and turnover rates that create favorable conditions for bed bug spread. The pattern is consistent: the neighborhoods with the highest percentage of rental units and the most population movement tend to have the most bed bug reports.

Tourism, Conventions, and Ski Travel

Denver's tourism industry is a significant driver of bed bug introduction and spread. The Colorado Convention Center hosts major events throughout the year, bringing tens of thousands of visitors who fill downtown hotels. The Great American Beer Festival, the National Western Stock Show, and numerous industry conferences draw crowds from across the country and around the world. Each visitor who stays in a Denver hotel or Airbnb represents a potential bed bug introduction point, either by bringing bed bugs in from their home city or by picking them up during their stay and carrying them to their next destination.

Ski travel adds another layer. Denver International Airport is the primary gateway for visitors heading to Colorado's ski resorts in Summit County, Eagle County, and the Roaring Fork Valley. Many of these travelers spend one or more nights in Denver-area hotels before or after their ski trip. The constant flow of guests through these properties means that even well-maintained hotels face ongoing bed bug exposure risk. Short-term rental properties (Airbnbs, Vrbos) in Denver neighborhoods are particularly vulnerable because they may lack the professional housekeeping and inspection protocols that major hotel chains employ. A bed bug introduced by one guest may not be detected until several subsequent guests have stayed in the unit, by which time the infestation may be established and multiple travelers may have unknowingly carried bed bugs home with them.

College and University Student Housing

The Denver metro is home to several colleges and universities, including the University of Denver, Metropolitan State University, Community College of Denver (on the Auraria Campus), the University of Colorado Denver, and Colorado State University in nearby Fort Collins. Student housing, both on-campus dormitories and off-campus apartments, is a well-documented bed bug vector. Students move frequently (every semester or every year), often bring used furniture into their apartments, share living spaces with multiple roommates, and may not recognize or report bed bug signs promptly. The annual cycle of move-in and move-out at the start and end of each academic year creates a burst of bed bug dispersal activity as infested furniture and belongings move from one address to another.

Thrift Store and Secondhand Furniture Culture

Denver has a strong thrift store and secondhand goods culture. Shops like ARC Thrift Stores, Goodwill, and numerous independent vintage and resale stores are popular throughout the metro. While reputable thrift stores inspect donations, used furniture is one of the most common vehicles for bed bug introduction. Upholstered chairs, couches, mattresses, bed frames, and nightstands can harbor bed bugs in seams, joints, and crevices for months, even without a human host. Beyond formal thrift stores, Denver residents commonly list used furniture on Facebook Marketplace, Craigslist, and Nextdoor, and it is not uncommon for furniture to be placed on curbs or in alleys for free pickup. Any used upholstered item acquired from an unknown source carries bed bug risk.

Mild Winters Still Bring Visitors

While Denver's winters bring cold temperatures (average January highs around 45 degrees F, with overnight lows in the teens and low twenties), the city experiences significantly more winter sunshine than many northern and midwestern cities. This mild, sunny winter climate, combined with proximity to ski resorts, means that Denver does not experience the kind of seasonal tourism slowdown that some cold-weather cities see. Visitors continue to flow through the metro year-round, maintaining continuous bed bug exposure risk. The cold itself does not kill bed bugs because the insects live indoors where temperatures remain in the 65 to 75 degree F range regardless of outdoor conditions. Bed bugs can be killed by prolonged exposure to temperatures below 0 degrees F, but this requires sustained exposure that does not occur in heated buildings.

How to Identify a Bed Bug Infestation in Denver

Early detection is the single most important factor in successfully treating a bed bug infestation. A small infestation caught early (a few bugs in one room) is far easier and less expensive to treat than an established infestation that has spread to multiple rooms or adjacent units. Knowing what to look for, where to look, and what other insects are commonly confused with bed bugs in Colorado will help you identify the problem quickly and accurately.

What Bed Bugs Look Like

Adult bed bugs are approximately the size and shape of an apple seed: 4 to 5mm long, flat (unless recently fed, when they become swollen and elongated), and reddish-brown in color. They have six legs, short antennae, and no wings. Nymphs (immature bed bugs) are smaller, ranging from 1mm at the first instar to about 4mm at the fifth instar. Young nymphs are translucent to pale yellow and become more visible after feeding, when they appear bright red from ingested blood. Bed bug eggs are tiny (about 1mm long, roughly the size of a pinhead), white or translucent, and are often found in clusters glued to surfaces in protected locations.

Signs of an Infestation

You do not need to see a live bed bug to confirm an infestation. Several other signs can indicate their presence, and in early infestations, you may find these signs before ever spotting a live bug. Look for the following.

Rusty or reddish-brown stains on sheets and mattresses. These blood stains are left when a recently fed bed bug is crushed by a sleeping person shifting position. They are typically small (the size of a pen tip to a small coin) and may appear as streaks or spots on sheets, pillowcases, and mattress surfaces, particularly along seams and edges.

Dark fecal spots. Bed bug excrement appears as small dark spots about the size of a period on a printed page. These spots may bleed into fabric like a marker stain. Fecal spots accumulate in harborage areas: along mattress seams, on box springs, on bed frame joints, behind headboards, on nightstands, and along baseboards near the bed. A concentration of fecal spots indicates an established hiding area where multiple bed bugs are congregating.

Shed skins (exoskeletons). Bed bugs molt five times as they progress from nymph to adult, shedding a translucent exoskeleton at each stage. Shed skins collect in harborage areas and are a reliable indicator of an active, reproducing population. They are pale tan or yellowish and shaped like the bug itself but are hollow and fragile.

Eggs and eggshells. Bed bug eggs are glued to surfaces in cracks, crevices, and seams near sleeping areas. Hatched eggshells appear as empty white casings. Finding eggs indicates active reproduction and an infestation that is growing, not declining.

A sweet, musty odor. In moderate to severe infestations, bed bugs release aggregation pheromones that produce a distinctive sweet, musty smell. This odor is most noticeable in heavily infested rooms and is sometimes described as smelling like coriander or overripe raspberries. If you notice an unusual odor in a bedroom or sleeping area that you cannot identify, it is worth investigating for bed bugs.

Bites in clusters or lines. Bed bug bites typically appear as raised, red welts in clusters or linear patterns on exposed skin (face, neck, arms, hands). However, an estimated 30% of people show no visible reaction to bed bug bites, and the bites themselves cannot be distinguished from other insect bites without additional evidence. Bites alone are not sufficient to confirm an infestation. For more detailed identification guidance, see our signs of bed bugs guide.

Where to Check in a Denver Home or Apartment

Start your inspection with the bed and work outward. In a Denver apartment, check the mattress seams and edges (the most common early harborage site), the box spring (flip it over and inspect the dust cover and frame), the bed frame and headboard (every joint, screw hole, and crack), nightstands and furniture within 5 feet of the bed, baseboards and the edge where carpet meets wall (or gaps between hardwood floorboards in older Denver apartments), electrical outlets and switch plates on walls near the bed, and upholstered furniture like couches and chairs, particularly in studio apartments where sleeping and sitting areas are close together.

Common Misidentifications in Colorado: Bat Bugs

Colorado has a relatively common bed bug lookalike that residents in many other states do not encounter: the bat bug. Bat bugs (Cimex pilosellus and Cimex adjunctus) are close relatives of bed bugs (Cimex lectularius) and are nearly impossible to distinguish with the naked eye. They are the same size, the same shape, and nearly the same color. Under magnification, the distinguishing feature is the length of the fringe hairs on the pronotum (the plate behind the head): bat bugs have longer fringe hairs than bed bugs.

Bat bugs are relevant in Colorado because many homes along the Front Range, particularly older homes, have bat colonies in attics, wall voids, chimneys, or behind exterior siding. When bats are present, bat bugs feed on them. When bats leave (either through seasonal migration or exclusion), bat bugs may migrate into living spaces in search of an alternative host. They can bite humans but cannot sustain a population on human blood alone. If you find what appears to be a bed bug infestation in a Denver home that also has bats (or has had bats in the past), there is a meaningful chance that the insects are bat bugs rather than bed bugs. The treatment approach differs: bat bug elimination requires addressing the bat colony (through exclusion, not extermination, as bats are protected wildlife in Colorado) and then treating the living spaces where bat bugs have migrated.

A pest control professional experienced in Colorado pest identification can distinguish between the two species. If you have any doubt, ask for a specimen to be examined under magnification before agreeing to a treatment plan. Treating for bed bugs when the actual problem is bat bugs will not resolve the issue if the bat colony is not addressed. For additional identification help, see our guide to getting rid of bed bugs.

Tenant Rights and Landlord Responsibilities in Denver

If you are renting an apartment or house in Denver and discover a bed bug infestation, understanding the legal framework that governs landlord and tenant responsibilities is essential. Colorado law and Denver-specific ordinances establish clear expectations for both parties, and following the correct procedures protects your rights and helps ensure the infestation is treated promptly and professionally.

Colorado Warranty of Habitability (CRS 38-12-503)

Colorado's Warranty of Habitability statute (CRS 38-12-503) requires landlords to maintain rental properties in a condition fit for human habitation. This includes keeping the property free from pest infestations that affect the health, safety, or livability of the unit. Bed bug infestations fall squarely within this requirement. Under this statute, landlords are obligated to respond to tenant reports of bed bugs, hire a licensed pest control company to inspect and treat the infestation, and pay for the treatment. The statute applies to all residential rental properties in Colorado, regardless of what the lease says. A lease provision that shifts pest control responsibility to the tenant does not override the statutory warranty of habitability. Landlords cannot contractually waive their obligation to maintain habitable conditions.

Denver Municipal Ordinances

In addition to state law, the City and County of Denver has municipal ordinances related to housing maintenance and pest control. Denver's housing code requires property owners to maintain rental units in a sanitary condition free from pest infestations. Denver Environmental Health is the city agency responsible for enforcing these standards. If a landlord fails to address a reported bed bug infestation, tenants can file a complaint with Denver Environmental Health, which can dispatch an inspector to verify the condition and issue violations. Landlords who receive housing code violations for pest infestations face fines and potential legal action if they do not remediate the problem within the timeframe specified in the violation notice.

How to Notify Your Landlord

If you discover or suspect a bed bug infestation in your Denver rental, notify your landlord in writing as soon as possible. Email is the most practical method because it creates a time-stamped record automatically. In your notification, include the date you first noticed signs or symptoms, a description of the signs you found (stains, bugs, bites, shed skins), the specific rooms and areas affected, and any photos or documentation you have gathered. Keep a copy of every communication with your landlord regarding the infestation. If you later need to file a complaint or pursue legal remedies, your written notification and the landlord's response (or lack of response) are the most important pieces of evidence. Send your notification via email and follow up with a certified letter if you do not receive a response within 5 to 7 business days.

If Your Landlord Fails to Act

If your landlord does not respond to your written notification or refuses to arrange professional treatment within a reasonable timeframe (generally 14 to 21 days), you have several options. File a complaint with Denver Environmental Health by calling 311 or submitting online through Denver's 311 portal. A housing inspector can verify the infestation and issue a code violation. Under CRS 38-12-507, tenants may be able to pursue rent reduction for the period during which the unit was uninhabitable due to the infestation. In severe cases where the landlord completely refuses to act, tenants may have grounds to terminate the lease. Before taking any of these steps, consult with a tenant rights organization or legal aid service (listed in the Resources section below) to ensure you follow the correct legal procedures. Self-help remedies (such as withholding rent) must follow specific legal steps to be valid under Colorado law.

How Bed Bugs Spread Between Units

In multi-unit apartment buildings, bed bugs frequently spread from one unit to adjacent units. They travel through wall voids, along plumbing and electrical conduits, through gaps in shared walls and ceilings, through cracks around door frames, and via shared laundry facilities. This means that even if your unit is successfully treated, re-infestation can occur if neighboring units are also infested and are not treated simultaneously. When reporting bed bugs to your landlord, request that adjacent units (on either side, above, and below) also be inspected. Building-wide inspection is the most effective approach in multi-unit buildings because it identifies the full scope of the infestation and allows coordinated treatment of all affected units. For more on dealing with bed bugs in rental housing, see our pest control for apartments guide.

Treatment Options for Bed Bugs in Denver

Several treatment methods are available for bed bug infestations in the Denver metro. The right approach depends on the size and severity of the infestation, the type of housing, your budget, and whether there are complicating factors like re-infestation risk from adjacent units. Here is what works, what each method involves, and how Denver's climate affects treatment effectiveness.

Heat Treatment

Heat treatment is the most effective single-visit bed bug elimination method. The process involves bringing industrial heating equipment into the infested space, raising the air temperature to 130 to 145 degrees F, and maintaining that temperature for several hours. At these temperatures, all life stages of bed bugs (eggs, nymphs, and adults) are killed. The treatment typically takes 6 to 8 hours for a full apartment and involves technicians monitoring temperatures throughout the space with wireless sensors to ensure every area reaches lethal temperature.

Heat treatment has several advantages. It kills all life stages in a single visit, including eggs, which are resistant to many chemical insecticides. It penetrates wall voids, furniture cavities, mattress interiors, and other hidden areas that chemical sprays cannot reach. It leaves no chemical residue, which is an advantage for households with children, pets, or chemical sensitivities. And it typically resolves the infestation in one day, which is far faster than the 4 to 6 week timeline for chemical treatment.

Denver's dry climate is relevant to heat treatment in one specific way: the low humidity along the Front Range (Denver's average annual relative humidity is about 40%) means that the air can absorb more moisture during the heating process. Some pest control companies in Denver use supplemental humidification during heat treatment to improve heat penetration into fabrics and upholstered items. The dry heat alone is effective, but adding moisture can improve penetration into dense materials. Ask your provider whether they use humidification as part of their heat treatment protocol.

The primary limitation of heat treatment is that it provides no residual protection. Once the heat dissipates (within hours of treatment completion), there is nothing to prevent bed bugs from re-entering the treated space. If you live in a multi-unit building where adjacent units may be infested, re-infestation is a real risk. For this reason, many Denver pest control companies recommend combining heat treatment with a targeted chemical application along baseboards, outlet covers, and other potential re-entry points to provide 30 to 60 days of residual protection at the perimeter. For more on heat treatment specifically, see our bed bug heat treatment cost guide.

Chemical Treatment

Chemical treatment involves applying a combination of insecticides to infested areas. A standard chemical treatment protocol includes a liquid residual insecticide applied to baseboards, bed frames, and furniture joints; a dust insecticide applied into wall voids (through electrical outlet openings), cracks, and crevices; and a contact spray for areas with visible bed bug activity. Some companies also use insect growth regulators (IGRs) that prevent nymphs from reaching reproductive maturity.

Chemical treatment requires multiple visits because most insecticides do not kill bed bug eggs. The initial treatment kills active nymphs and adults. Eggs that are present at the time of treatment hatch 6 to 10 days later, and the follow-up treatment (scheduled 10 to 14 days after the initial visit) kills these newly hatched nymphs before they can reproduce. Most protocols require 2 to 3 visits over a 4 to 6 week period. Skipping follow-up visits is one of the most common reasons for treatment failure. The full treatment process takes longer than heat treatment, but chemical treatment is significantly less expensive.

One consideration for Denver's dry climate: bed bug eggs may experience slightly lower hatch rates in very dry conditions compared to humid environments, but this effect is not significant enough to change treatment protocols. The desiccant effect of Denver's dry air may also marginally benefit the performance of diatomaceous earth and silica-based dust products, which work by damaging the waxy outer layer of bed bug exoskeletons and causing dehydration. These products are often used as part of a comprehensive chemical treatment in cracks, crevices, and wall voids.

Combination Treatment

Many Denver pest control companies offer combination treatment that pairs heat treatment with targeted chemical application. This approach uses heat to kill the existing infestation (all life stages, in one visit) and then applies residual chemicals along entry points and perimeter areas to provide ongoing protection against re-infestation. Combination treatment is particularly recommended in multi-unit buildings where re-infestation from neighboring units is a concern. The cost is typically 10% to 20% higher than heat treatment alone but provides the most comprehensive protection.

Cryonite (Freeze Treatment)

Cryonite is a non-chemical treatment that uses compressed carbon dioxide to freeze bed bugs on contact. A technician sprays CO2 "snow" directly onto bed bugs and their harborage areas, killing them through rapid freezing. Cryonite is useful as a supplemental treatment for specific, localized areas where chemical application is not desirable (near electronics, in clean rooms, or in sensitive environments). It is not typically used as a standalone treatment for an entire apartment because it only kills bugs on contact and has no residual effect. Cryonite is available from some Denver pest control companies as an add-on to chemical or heat treatment.

Denver's Dry Climate and Egg Resilience

Bed bug eggs are designed to survive a range of environmental conditions, and Denver's dry climate does not significantly reduce their viability under normal indoor conditions. The eggs have a protective coating (chorion) that resists desiccation. However, at extremely low humidity levels (below 30% relative humidity, which can occur in Denver homes during winter when heating systems run continuously), egg hatch rates may decline slightly. This is not a reliable control method and should not be relied upon as part of a treatment strategy. Professional treatment (heat, chemical, or combination) remains necessary regardless of ambient humidity.

Bed Bug Treatment Cost in Denver

Bed bug treatment costs in the Denver metro vary significantly based on the treatment method, the size of the affected area, and the severity of the infestation. Here is what to expect for the most common treatment approaches.

Denver's bed bug treatment costs are generally in line with national averages or slightly below, reflecting the metro's lower cost of living compared to coastal cities. The factors that most affect price are the treatment method (heat is the most expensive, chemical is the least), the number of rooms affected, the severity of the infestation, whether adjacent units need treatment, and whether the company includes a guarantee or warranty with retreatment at no additional cost.

For detailed pricing breakdowns, see our bed bug treatment cost guide for national averages and our bed bug heat treatment cost guide for heat-specific pricing. For Denver pricing across all pest types, see our Denver pest control cost guide.

Choosing a Bed Bug Exterminator in Denver

Not all pest control companies are equally qualified to treat bed bugs. Bed bug treatment requires specialized training, equipment, and experience that goes beyond general pest control. Here is what to look for when choosing a bed bug exterminator in the Denver metro.

Colorado Department of Agriculture License

All pest control companies operating in Colorado must be licensed by the Colorado Department of Agriculture (CDA). Verify that the company holds a current CDA pest control business license and that the technicians who will perform the treatment hold individual applicator certifications. You can verify a company's license status through the CDA's online database. An unlicensed company operating in Colorado is operating illegally, and you have no recourse if something goes wrong.

Bed Bug-Specific Experience

General pest control experience is not the same as bed bug experience. Ask how many bed bug treatments the company has performed, whether bed bugs are a primary focus of their business, and how long they have been treating bed bugs specifically. Companies that treat bed bugs as a core service will have invested in specialized equipment (industrial heaters, temperature monitoring systems, or canine detection teams) and will have technicians with specific bed bug training. A company that treats bed bugs occasionally as part of a general pest control practice is less likely to have the expertise needed for complex infestations, particularly in multi-unit buildings.

Inspection Method

Before treatment, a thorough inspection is essential to determine the scope of the infestation. The two primary inspection methods are visual inspection (a trained technician manually inspects all potential harborage areas) and canine inspection (a trained bed bug detection dog sweeps the space and alerts to areas with live bed bug scent). Canine inspection is faster, can cover larger areas efficiently, and can detect bed bugs hidden in wall voids and other areas that are difficult to inspect visually. However, canine inspection quality depends heavily on the training and certification of both the dog and the handler. Ask whether the detection team is certified by a recognized organization such as the National Entomology Scent Detection Canine Association (NESDCA) or the World Detector Dog Organization (WDDO). False positives and false negatives are both possible, so a reputable company will confirm any canine alert with a visual inspection before recommending treatment.

Preparation Requirements

Every bed bug treatment requires some level of preparation by the homeowner or tenant (laundering bedding and clothing, decluttering, moving furniture away from walls, etc.). However, the extent of preparation varies significantly between companies and treatment methods. Some companies require extensive preparation that can take days, while others offer "prep-lite" or "no-prep" heat treatment protocols that minimize the burden on the resident. Ask specifically what preparation is required, how much time you will need, and what happens if preparation is not completed to the company's standards before the treatment date. A company that provides a detailed, written preparation checklist is demonstrating professionalism and setting clear expectations.

Guarantee and Retreatment Policy

A reputable bed bug treatment company should offer a guarantee that includes retreatment at no additional cost if bed bugs are detected within a specified period after treatment (typically 30 to 90 days). Ask about the guarantee terms: what is the duration, what is required for the guarantee to remain valid (some require follow-up inspections), and what happens if bed bugs are found during the guarantee period. Be cautious of companies that do not offer any guarantee or that impose extensive conditions that effectively void the guarantee. The guarantee is an indicator of the company's confidence in its treatment protocol.

Get Multiple Quotes

For any bed bug treatment, get at least 2 to 3 quotes from different companies. This allows you to compare pricing, treatment methods, preparation requirements, and guarantee terms. Be wary of quotes that are dramatically lower than the competition, as this may indicate corner-cutting on treatment thoroughness, chemical quality, or follow-up visits. Conversely, the most expensive quote is not necessarily the best. Compare the total value including the treatment method, the number of visits included, the preparation support offered, and the guarantee terms. For guidance on when professional help is warranted versus when you might wait, see our when to call an exterminator guide.

Preventing Bed Bug Infestations in Denver

Prevention is far less expensive and disruptive than treatment. While it is impossible to guarantee that you will never encounter bed bugs, the following practices significantly reduce your risk of introduction and establishment.

Hotel and Airbnb Inspection During Travel

Denver's proximity to Colorado's ski resorts means that many Denver residents travel frequently and stay in hotels, lodges, and short-term rentals throughout the state. Before settling into any hotel room or rental, perform a quick inspection. Pull back the sheets and check the mattress seams, particularly along the head of the bed. Check behind the headboard if it can be moved. Inspect the nightstand drawers and the luggage rack area. If you see any signs of bed bugs (live bugs, shed skins, fecal spots, or blood stains), request a different room (not an adjacent room, as infestations can span multiple units) or leave the property. Keep your luggage on hard surfaces or luggage racks, not on the bed, carpeted floor, or upholstered furniture.

Mattress and Box Spring Encasements

Encasements are zippered covers that fully enclose your mattress and box spring, eliminating hiding spots and making early detection easier. A quality bed bug encasement has a tight zipper with a small tooth size that prevents bed bugs from entering or escaping through the closure. Encasements cost $30 to $80 per mattress and are one of the most cost-effective preventive measures available. They also make inspection simpler because any bed bugs on the encasement surface are visible against the smooth, light-colored fabric, rather than hidden in seams and folds.

Interceptor Traps

Bed bug interceptor traps are small plastic dishes that fit under bed legs. The outer well has a rough surface that allows bed bugs to climb in, but the smooth inner walls prevent them from climbing out. Interceptors serve as both a detection tool (finding bugs in the traps confirms their presence) and a barrier (preventing bed bugs from climbing up bed legs to reach sleeping hosts). Place interceptors under all four legs of every bed in the home. Check them weekly. Finding even one bug in an interceptor is cause for immediate professional inspection.

Secondhand Furniture Inspection

Before bringing any used furniture into your Denver home, inspect it carefully for bed bug signs. Check every seam, joint, crack, and crevice with a flashlight. Pay particular attention to upholstered items (couches, chairs, mattresses), bed frames, nightstands, and dressers. Never pick up upholstered furniture from curbs, alleys, or unknown sources. If you purchase used furniture from a thrift store or online marketplace, inspect it before bringing it inside and consider treating it with a portable steamer (which can kill bed bugs on contact) before placing it in your living space.

Post-Travel Laundry Protocol

After any overnight travel (hotels, vacation rentals, visiting friends or family), launder all clothing and fabric items from your luggage on the highest heat setting your fabrics can tolerate, followed by at least 30 minutes in a hot dryer. The dryer heat (typically 135 to 155 degrees F on high) kills all life stages of bed bugs. Inspect your luggage exterior before bringing it inside, and store suitcases away from bedrooms when not in use (a garage, basement, or closet far from sleeping areas is ideal).

Shared Laundry Caution

Many Denver apartments have shared laundry facilities on-site or residents use public laundromats. Shared laundry equipment itself is not a significant bed bug risk, but the surfaces around it can be. Transport your laundry to and from the laundry room in sealed plastic bags (not open baskets or bags set on the floor). Do not place clean laundry on folding tables or other shared surfaces before bagging it. Transfer clean, hot items from the dryer directly into clean bags or baskets. This prevents bed bugs from hitchhiking on your clean laundry.

Regular Inspection Habit

Make bed bug inspection part of your routine, particularly if you live in a multi-unit building. Check your mattress seams and bed frame monthly. Look for fecal spots, shed skins, and live bugs. Check interceptor traps weekly. Early detection, when only a few bugs are present, makes treatment dramatically simpler, faster, and less expensive than waiting until the infestation has spread to multiple rooms.

Denver Resources for Bed Bug Infestations

The following resources are available to Denver residents dealing with bed bug infestations.

Denver Environmental Health. The city agency responsible for housing code enforcement, including pest infestations in rental properties. File a complaint by calling Denver's 311 line or submitting online through the Denver 311 portal. An inspector can verify a bed bug infestation and issue violations to property owners who fail to address the problem.

Colorado Department of Agriculture (CDA). The state agency that licenses pest control companies in Colorado. Use their online database to verify that any company you are considering is properly licensed. The CDA also accepts complaints about licensed pest control companies that perform substandard work.

Colorado Legal Services. Provides free legal assistance to low-income Colorado residents, including tenant rights cases involving habitability issues like bed bug infestations. If your landlord is not responding to your bed bug report, Colorado Legal Services can advise you on your rights and options.

Legal Aid of Colorado. Another free legal resource for tenants facing habitability issues. Legal Aid of Colorado provides advice, representation, and referrals for rental housing disputes, including pest-related habitability claims.

Colorado Division of Housing. The state agency that oversees fair housing and tenant rights at the state level. While they do not directly handle individual pest complaints, they can provide information about your rights under Colorado law and direct you to appropriate resources.

Denver Metro Tenants' Organizations. Several community-based organizations in the Denver metro provide tenant rights education, advocacy, and support. These groups can help you understand your rights, navigate the complaint process, and connect with legal resources if needed.
