Pest Control Before Moving In (Dallas Guide)

Last updated: March 25, 2026

By James — Founder of Pest Control Pricing

Yes, you should get pest control before moving into a Dallas home, and it costs $200 to $500 for a comprehensive pre-move-in package. The Dallas-Fort Worth metro has year-round pest pressure from German cockroaches, fire ants, Eastern subterranean termites, roof rats, and mosquitoes. Treating an empty home is faster, cheaper, and more effective than treating around furniture and unpacked boxes. The previous occupants may have had untreated pest issues, and empty homes that sit between tenants or sales attract rodents and cockroaches that are looking for shelter.

This guide covers exactly what services to request before your move-in date, what to ask the seller about pest history, which Dallas-specific pests to watch for in a new home, what the pest inspector should check that a standard home inspector misses, and how to maintain a pest-free home after you are settled.

Why Should You Treat a Dallas Home Before Moving In?

Pre-move-in pest treatment is one of the most cost-effective steps you can take as a new homeowner or renter in Dallas. The reasons are practical and specific to the DFW market.

Previous Owners May Have Had Untreated Issues

Not every homeowner maintains active pest control, and pest problems do not always surface during a short walkthrough or home inspection. German cockroaches, in particular, can be present in a home's kitchen and bathroom cabinets, behind appliances, and in wall voids without being visible during a daytime showing. If the previous occupants lived with a low-level cockroach issue (or a high-level one they were too embarrassed to mention), you inherit those cockroaches when you move in. A pre-move-in treatment before your belongings arrive addresses this risk when the home is empty and every surface is accessible.

Empty Homes Attract Rodents and Cockroaches

Homes that sit vacant between owners or between tenants are vulnerable to pest entry. Rodents (mice and rats) are attracted to the shelter of an unoccupied structure, especially during temperature extremes. American cockroaches enter through plumbing drains that have dried out (the water trap in infrequently used drains evaporates, creating an open path from the sewer system into the home). If the home was vacant for more than 2 to 3 weeks, run water in every drain (sinks, bathtubs, showers, floor drains) to restore the water traps, and schedule a pest inspection before moving in.

Dallas Climate Supports Year-Round Pest Activity

The Dallas-Fort Worth metro has a subtropical climate with mild winters (average January low of 36 degrees F) and hot, humid summers. This climate supports year-round activity for cockroaches, termites, ants, and rodents. Unlike northern cities where winters provide a natural break in pest pressure, Dallas homes face continuous pest exposure in every season. There is no "safe" time of year to skip pre-move-in treatment.

German Cockroaches Do Not Leave with the Moving Truck

German cockroaches (Blattella germanica) are small (1/2 to 5/8 inch), light brown cockroaches that live exclusively indoors. Unlike American cockroaches ("water bugs") that enter from outside, German cockroaches are introduced into homes through infested grocery bags, cardboard boxes, used furniture, and appliances. Once established, they live and breed inside wall voids, behind kitchen cabinets, under sinks, inside appliances, and in bathroom vanities. When the previous occupants move out, the cockroaches stay. They are not carried away with the furniture. If the seller or previous tenant had German cockroaches, you have German cockroaches until the home is professionally treated.

It Is Easier and Cheaper to Treat an Empty House

Professional pest treatment in an empty home is more thorough and less expensive than treating around furniture, stacked boxes, and a full kitchen. The technician has unobstructed access to all baseboards, cabinet interiors, closet floors, bathroom vanities, and behind where appliances will go. Treatment products can be applied to all cracks, crevices, and surfaces without the need to move belongings or cover food items. A pre-move-in treatment that takes 2 hours in an empty house might take 3 to 4 hours and require more prep work in a furnished one.

What 4 Services Should You Request Before Moving In?

A comprehensive pre-move-in pest treatment in Dallas should include four specific services. Some pest control companies offer a bundled "move-in package" that covers all four. Others price each service separately. Either way, request all four for complete protection.

Service 1: General Pest Treatment ($100 to $200)

The general pest treatment is the core of the pre-move-in package. A technician treats the interior of the home with professional-grade insecticide applied as crack-and-crevice treatment along all baseboards, inside all kitchen and bathroom cabinets, behind and under the refrigerator, stove, and dishwasher, in closets, and around all plumbing penetrations. The exterior receives a perimeter spray treatment around the foundation, entry doors, garage door frame, and window frames.

This treatment targets German cockroaches, American cockroaches, ants (including fire ants entering the structure), spiders, silverfish, crickets, and other common household insects. In an empty home, the technician can treat every surface without obstruction, providing more thorough coverage than a treatment performed after move-in. The treatment provides 60 to 90 days of residual protection, which bridges the critical first weeks as you settle in.

Service 2: Termite Inspection ($75 to $150)

A termite inspection is essential for any home purchase in Dallas. Most DFW lenders require an NPMA-33 Wood-Destroying Organism (WDO) report before approving a mortgage. Even if your lender does not require it, requesting a termite inspection is strongly recommended. Dallas falls in the USDA's moderate-to-heavy termite infestation probability zone, and Eastern subterranean termites are active in soil throughout the metro area year-round.

The termite inspector examines the full structure: exterior foundation walls for mud tubes, interior baseboards and wood framing for damage, the crawl space or basement (if present) for moisture and termite evidence, the attic for termite and other wood-destroying organism activity, and the garage for slab-to-wall junction activity. The resulting report documents whether active termites, previous damage, or conditions conducive to infestation were found. If active termites are discovered, treatment costs $800 to $3,500 depending on the method (liquid barrier, bait stations, or combination). For detailed termite treatment pricing, see our termite treatment cost guide and Dallas termite treatment cost page.

Service 3: Rodent Exclusion Inspection ($100 to $200)

A rodent exclusion inspection identifies how and where rodents can enter the home. The inspector checks the attic for droppings, nesting material, gnaw marks, and grease trails (rats leave dark, oily marks along their regular travel paths). The garage is inspected for entry points around the garage door, utility penetrations, and gaps at the wall-ceiling junction. The roof-soffit intersection, plumbing vent pipes, gable vents, and utility line entries are checked for gaps that would allow roof rat access.

If entry points are found, the inspector recommends exclusion work (sealing the gaps with steel mesh, hardware cloth, metal flashing, or expanding foam). Rodent exclusion sealing costs $200 to $800 depending on the number and complexity of the entry points. Addressing entry points before you move in prevents a rodent problem from developing after you bring in food and create the scent environment that attracts foraging rodents. For detailed rodent exclusion pricing, see our rodent exclusion cost guide.

Service 4: Mosquito Yard Treatment ($75 to $150)

Dallas has a 9-month mosquito season running from March through November. If you are moving in during this window, a mosquito yard treatment before your first evening on the patio makes a significant difference in livability. The technician applies barrier spray to vegetation, fence lines, under decks, and in shaded areas where mosquitoes rest. Standing water sources on the property are identified and treated with larvicide or recommended for elimination.

A single mosquito treatment provides 21 to 30 days of reduced mosquito activity, giving you time to settle in and decide whether ongoing monthly service ($70 to $100 per month) is worth the cost for your property. For homes near White Rock Lake, creek corridors, or in areas with heavy irrigation, ongoing treatment is usually necessary throughout the season. For detailed mosquito treatment pricing, see our Dallas mosquito treatment cost page and our Dallas mosquito season guide.

What Should You Ask the Seller About Pest History?

Texas law requires sellers to complete a Seller's Disclosure Notice (Texas Property Code Section 5.008), which includes questions about known defects and conditions affecting the property. While pest history is not always disclosed in detail, you or your real estate agent can and should ask these specific questions during the transaction process.

Previous Pest Treatments

Ask whether the home has been professionally treated for pests, when the last treatment occurred, which pest(s) were targeted, and which company performed the work. This tells you whether the home has had active pest issues and provides context for the current condition. If the seller had regular quarterly service, the home is likely in good shape. If there has been no professional treatment, pest pressure may have built up unchecked.

Known Termite Damage or Treatment

Ask specifically whether the home has ever had termite treatment, whether there is a termite bond (annual service agreement) in place, and whether the bond is transferable to the new owner. In Dallas, many homes have active termite bonds that can transfer at closing, saving you the cost of establishing a new one. If the home has had previous termite treatment, ask what method was used (liquid barrier, bait stations, or both), when it was applied, and whether any structural damage was found and repaired. Check whether the original termite treatment warranty is still active.

Active Pest Control Contracts

Some homes have active pest control service contracts (quarterly general pest, mosquito, fire ant, or termite monitoring programs). Ask whether any contracts are in place and whether they transfer to the new owner. If a transferable contract exists, it may save you the setup fee for new service and provide continuity of protection during the ownership transition.

When Was the Last Termite Inspection?

Even if the lender requires a current inspection for the purchase, knowing when the previous termite inspection occurred provides useful context. If the home was inspected a year ago and no issues were found, that is reassuring. If the home has never been inspected for termites (more common than you might expect, especially with homes purchased for cash without lender requirements), that is a data gap you should address with a current inspection.

Wood-Destroying Insect Report from Original Purchase

Ask for a copy of the NPMA-33 WDO report from when the seller originally purchased the home. This provides a historical baseline: what the inspection found (or did not find) at that time. Comparing the original report to your current purchase inspection can reveal new issues that developed during the seller's ownership.

History of Flooding or Moisture Issues

Moisture attracts termites, cockroaches, and rodents. Ask whether the home has experienced flooding, standing water in the crawl space or garage, persistent plumbing leaks, foundation drainage issues, or any moisture-related repairs. Dallas's clay soil and periodic heavy thunderstorms create drainage challenges, and homes with moisture history face elevated pest pressure. If the seller discloses moisture issues, factor additional pest prevention measures (dehumidification, drainage correction, enhanced termite monitoring) into your planning.

What Dallas-Specific Pests Should You Watch for in a New Home?

Dallas has a distinctive pest profile shaped by its climate, geography, and urban development patterns. The following pests are the most common concerns for new homeowners in the DFW metro.

German Cockroaches Left Behind by Previous Occupants

German cockroaches are the number one pest concern when moving into a previously occupied Dallas home. These small (1/2 to 5/8 inch), light brown cockroaches with two dark parallel stripes on the pronotum (the shield-like plate behind the head) live exclusively indoors. They do not come in from outside; they are introduced through infested items and they stay. German cockroaches breed rapidly (a single female produces 4 to 6 egg cases in her lifetime, each containing 30 to 40 eggs), and a small population can become a severe infestation within weeks.

Before moving in, check kitchen cabinets (especially under the sink and in corner cabinets), behind the refrigerator and stove, inside the dishwasher door frame, in bathroom vanities, and around plumbing penetrations. Look for live cockroaches, dead cockroaches, egg cases (small, dark brown, purse-shaped capsules approximately 1/4 inch long), and droppings (small, dark specks resembling ground pepper, concentrated near harborage areas). If German cockroaches are found, professional treatment before moving in is essential. Do not move your belongings into a home with an active German cockroach population; you risk infesting your own items.

Fire Ants in Every Dallas Yard

Red imported fire ants (Solenopsis invicta) are present in virtually every yard in the Dallas-Fort Worth metro. Their mounds appear as irregularly shaped domes of loose soil, typically 6 to 18 inches in diameter, in lawns, landscape beds, along driveways, and around utility boxes. Fire ants sting aggressively when their mound is disturbed, and they produce a painful, burning sting that forms a characteristic white pustule within 24 hours.

Before moving in, walk the entire yard and identify all fire ant mounds. Treat them with granular bait (broadcast across the yard) or individual mound treatment (drenching each mound with liquid insecticide or applying granular contact killer). Fire ant treatment costs $50 to $100 as an add-on to your pre-move-in pest package, or you can apply over-the-counter fire ant bait yourself for $10 to $20. For detailed fire ant treatment costs, see our Dallas ant exterminator cost guide.

Termites in Older Dallas Neighborhoods

Established Dallas neighborhoods with older construction are at elevated termite risk. Homes in Lakewood, Oak Cliff, East Dallas, M Streets, Hollywood Heights, and other neighborhoods built before the 1970s may have pier-and-beam (crawl space) foundations with wooden structural members in close proximity to the soil. These older homes may or may not have been treated for termites during their lifetime, and previous termite damage may have been repaired without full retreatment of the soil.

Newer construction in the suburbs (Frisco, McKinney, Allen, Prosper, Celina) was typically pre-treated with termiticide during construction, but this pre-treatment lasts only 5 to 10 years. If you are buying a home that is more than 5 years old in any Dallas neighborhood, a termite inspection is essential regardless of construction age.

Roof Rats in Neighborhoods with Mature Trees

Roof rats (Rattus rattus) are increasingly common in established Dallas neighborhoods with mature trees, particularly areas with citrus trees (Meyer lemon, satsuma orange) and large hardwoods. Neighborhoods like Lakewood, Greenville Avenue corridor, University Park, Highland Park, Lake Highlands, and East Dallas have significant roof rat populations. Roof rats are excellent climbers that travel through tree canopies and along power lines to access attics through gaps at the roofline, plumbing vent pipes, and soffit vents.

Signs of roof rat activity in a new home include droppings in the attic (dark, spindle-shaped pellets approximately 1/2 inch long), gnaw marks on wood and wiring in the attic, grease trails (dark, oily marks along rafters and roofline edges where rats travel repeatedly), and sounds of scratching or running in the ceiling or walls at night. If you find evidence of roof rats during your pre-move-in inspection, rodent exclusion and trapping should be completed before you move in. For rodent removal pricing, see our rodent exterminator cost guide.

Mosquitoes Breeding in Yard Drainage

Dallas's clay soil and periodic heavy thunderstorms create standing water throughout the metro. Low spots in yards, clogged gutters, poor drainage around foundations, birdbaths, and landscape features all become mosquito breeding sites. If you are moving in during the March-through-November mosquito season, assess the yard for standing water and drainage issues early. Correcting drainage problems and eliminating standing water sources is the single most effective mosquito reduction measure. Supplement with professional barrier spray ($75 to $150) for immediate relief.

What Should the Pest Inspector Check That a Home Inspector Misses?

Standard home inspectors are generalists who evaluate the overall condition of the structure, roof, plumbing, electrical, and HVAC systems. They note pest evidence if they happen to see it, but they do not specifically inspect for pest activity, entry points, or conducive conditions the way a licensed pest control professional does. A dedicated pest inspection covers the following areas that a home inspection typically does not.

Attic: Rodent Droppings and Nesting

A pest inspector specifically looks for rodent droppings, nesting material (shredded insulation, paper, fabric), gnaw marks on wiring and wood, grease trails along rafters, and urine staining on insulation. These signs indicate current or recent rodent activity that a home inspector may not check for or recognize. Rodent activity in the attic can also compromise insulation effectiveness and create fire risk from gnawed wiring.

Weep Holes: Termite Mud Tubes

Weep holes in brick veneer construction are small gaps at the base of the exterior brick that allow moisture to drain from the wall cavity. Termites can build mud tubes through weep holes to access the wood framing behind the brick. A pest inspector checks weep holes specifically for mud tube construction, which a standard home inspector may not examine at this level of detail.

Garage: Rodent Entry Points and Gnaw Marks

The garage is one of the most common pest entry points in Dallas homes. A pest inspector checks the garage door seal (the gap between the door and the floor when closed), the utility penetrations (gas line, water line, electrical conduit entering through the garage wall), the ceiling-wall junction (rats can enter the attic from the garage through gaps at the top of the wall), and around stored items for droppings and gnaw marks.

Yard: Fire Ant Mounds

A pest inspector surveys the entire yard for fire ant mounds, noting their size, number, and proximity to the home, play areas, and walkways. This information helps determine whether broadcast treatment (the entire yard) or targeted mound treatment is appropriate. A standard home inspector may note fire ants in a general comment but does not typically map mound locations or assess infestation severity.

Eaves and Overhangs: Wasp and Mud Dauber Nests

Paper wasp nests, mud dauber tubes, and carpenter bee holes in eaves, soffits, and overhangs are common in Dallas homes. A pest inspector identifies active nests and recommends treatment or removal before you move in. This is a safety issue, especially if nests are near entry doors, covered patios, or areas where children play.

AC Line Penetrations

The refrigerant lines for the AC system enter the home through a wall penetration that is often poorly sealed with degraded foam or caulk. This gap is a common entry point for cockroaches, ants, spiders, and occasionally rodents. A pest inspector checks the seal and recommends resealing if gaps are present.

Plumbing Penetrations

Where plumbing lines enter through the slab or crawl space into the home, gaps often exist around the pipes. These gaps provide direct access from the soil (where termites live) or from the crawl space (where rodents harbor) into the living space. A pest inspector identifies gaps around plumbing penetrations and recommends sealing with appropriate materials (steel wool and caulk for rodent prevention, chemical-compatible sealant for termite prevention).

What Does Pre-Move-In Treatment Include Step by Step?

Here is what to expect from a comprehensive pre-move-in pest treatment in a Dallas home, from scheduling through completion.

Step 1: Schedule 3 to 7 Days Before Move-In

Contact a licensed pest control company at least 1 to 2 weeks before your planned move-in date to schedule the service. Request the full pre-move-in package (general pest treatment, termite inspection, rodent exclusion inspection, and mosquito yard treatment if seasonal). The technician needs access to the interior, so coordinate with your real estate agent or landlord for key access. The visit typically takes 1.5 to 3 hours for a standard single-family home.

Step 2: Interior Treatment

The technician treats all kitchen cabinets (interior shelves, under-sink area, corner cabinets) and bathroom vanities with crack-and-crevice application of professional-grade insecticide. All baseboards throughout the home receive treatment, with particular attention to exterior walls and areas near plumbing penetrations. Behind and beneath built-in appliances (refrigerator, stove, dishwasher) is treated. Closet baseboards and floors are treated. Window frames and door frames on the ground floor receive treatment. Utility rooms, laundry areas, and the water heater closet are treated.

In an empty home, this interior treatment is thorough because every surface is accessible. After you move in and fill the cabinets with dishes and food, future treatments require preparation (clearing cabinets, covering food, moving items away from walls) that is not necessary in an empty home.

Step 3: Exterior Perimeter Spray

The technician applies residual insecticide around the full exterior perimeter of the home: along the foundation, around all entry doors, around the garage door frame, around ground-floor windows, and at utility penetration points. The perimeter spray creates a barrier that kills insects crossing from the exterior into the home. Application extends 2 to 3 feet up the foundation wall and 2 to 3 feet out from the foundation on the ground.

Step 4: Crack-and-Crevice Treatment

Beyond the perimeter spray, the technician applies targeted treatment in specific cracks and crevices where pests harbor: expansion joints in the slab, gaps around pipe penetrations, weep holes (treated with dust or aerosol), gaps at the sill plate (where the wood framing meets the foundation), and around electrical boxes on exterior walls. This targeted application reaches pests in their harborage rather than waiting for them to cross the perimeter barrier.

Step 5: Attic Inspection

The technician enters the attic (if accessible and safe) to inspect for rodent activity (droppings, nesting, gnaw marks, grease trails), wasp or bee nests, and evidence of other pest activity. The attic inspection provides critical information about rodent entry points and current activity that is not visible from inside the living space. If rodent evidence is found, the technician recommends exclusion and trapping services.

Step 6: Garage Treatment

The garage receives interior perimeter treatment along all walls, in corners, around the garage door frame, and at the wall-ceiling junction. The garage is the primary pest entry point in most Dallas homes, and thorough treatment of this space is essential. The technician also inspects the garage door seal and recommends a door sweep or weatherstripping if the gap exceeds 1/4 inch.

Step 7: Yard Treatment (Fire Ants and Mosquitoes)

If you have requested yard services, the technician treats fire ant mounds (broadcast bait or individual mound treatment) and applies mosquito barrier spray to vegetation, fences, and shaded areas throughout the yard. Standing water sources are identified and treated with larvicide or flagged for elimination. The technician provides a source reduction assessment, identifying drainage issues and water-holding features that will continue to breed mosquitoes if not corrected.

Step 8: Documentation and Recommendations

The technician provides a written report or service ticket documenting what was treated, what was found during inspection, and any recommended follow-up services (rodent exclusion, termite treatment, drainage correction). Keep this documentation for your records. It serves as a baseline for the condition of the home at the time of your move-in and is useful if pest issues develop later.

How Do You Maintain a Pest-Free Dallas Home After Moving In?

The pre-move-in treatment provides a clean starting point. Maintaining pest-free conditions in the Dallas climate requires ongoing effort, either through professional quarterly service or consistent DIY prevention.

Option 1: Quarterly Professional Pest Control ($100 to $175 per Quarter)

A quarterly pest control plan is the most popular ongoing service for Dallas homeowners. Every 3 months, a technician retreats the exterior perimeter, applies targeted interior treatment as needed, removes spider webs from eaves and entry areas, inspects for new termite or rodent activity, and treats fire ant mounds that have appeared since the last visit.

Quarterly service provides reliable, consistent protection with minimal effort on your part. The technician manages the treatment schedule, adjusts for seasonal pest pressure, and catches emerging issues before they become infestations. For most Dallas homeowners, quarterly service at $400 to $700 per year is the most cost-effective approach to pest management. For detailed plan pricing, see our pest control plans and pricing guide.

Option 2: DIY Perimeter Spray ($15 to $30 per Season)

If you prefer to manage pest control yourself, the most effective DIY approach is perimeter spray with a professional-grade concentrate. Bifenthrin-based concentrates (sold under brands like Bifen I/T, Talstar, and generic equivalents) are available at hardware stores and online for $15 to $30 per gallon of concentrate, which mixes into enough solution to treat a standard home perimeter 4 to 6 times.

Apply the perimeter spray every 60 to 90 days along the foundation, around all entry doors, around the garage door, and along window frames at ground level. This creates a residual barrier similar to (though somewhat less thorough than) professional service. DIY perimeter spray works well for homes with low to moderate pest pressure. For heavy cockroach, rodent, or termite issues, professional treatment is necessary.

Ongoing Prevention Habits for Dallas

• Seal food in airtight containers. Do not leave pet food, birdseed, or open food packages accessible. German cockroaches and rodents are attracted to available food sources.
• Take trash out nightly. Do not leave kitchen trash overnight in the home, especially during warm months when cockroach activity is highest.
• Fix plumbing leaks promptly. Moisture under sinks, around toilets, and at exterior hose bibs attracts cockroaches, termites, and rodents.
• Run water in infrequently used drains. Floor drains in garages, guest bathrooms, and laundry rooms can dry out, allowing sewer cockroaches (American cockroaches) to enter through the drain. Run water in every drain at least once a month to maintain the water trap.
• Keep the yard mowed and debris-free. Overgrown vegetation and debris provide harborage for fire ants, rodents, and mosquitoes. Mow regularly, trim bushes away from the foundation, and remove leaf litter and yard waste.
• Treat fire ant mounds as they appear. New fire ant mounds appear regularly in Dallas yards, especially after rain. Treat individual mounds promptly with over-the-counter granular bait or contact killer. Do not leave mounds untreated near walkways, play areas, or the foundation.
• Trim tree branches at least 6 feet from the roofline. In neighborhoods with roof rat activity, keeping tree branches trimmed away from the roof eliminates the primary access route for roof rats entering the attic. This is one of the most effective and least expensive rat prevention measures.
• Clean gutters twice per year. Clogged gutters hold standing water (mosquito breeding) and create moisture against the fascia board (attractive to termites and carpenter ants). Clean gutters in spring before mosquito season and in fall after leaves drop.
• Eliminate standing water after every rainstorm. Walk the property after rain and dump, drain, or treat any standing water in flower pot saucers, tire swings, tarps, low spots, and landscape features. Mosquitoes can breed in any water that sits undisturbed for more than 5 days.

How Do You Verify a Dallas Pest Control Company Is Licensed?

Hiring an unlicensed pest control operator puts you at risk for ineffective treatment, improper pesticide application, and no recourse if something goes wrong. Texas regulates pest control through a specific licensing system that you can and should verify before allowing any company to treat your home.

Texas Pest Control License (TPCL) Through TDLR

All pest control companies operating in Texas must hold a valid Texas Pest Control License issued through the Texas Department of Licensing and Regulation (TDLR). The license is issued to the company and to individual certified applicators who perform the work. The company must have a licensed certified applicator responsible for overseeing all work performed.

Structural vs. Lawn Pest Control: Separate Licenses

Texas separates pest control licensing into categories. Structural pest control covers indoor pests (cockroaches, ants, spiders, rodents), termites, and bed bugs. Lawn and ornamental pest control covers outdoor pests (fire ants, mosquitoes, grubs, lawn-damaging insects). A company that treats both indoor pests and yard pests should hold both license categories. If a company only treats indoor pests but also applies mosquito or fire ant treatment to your yard, verify that they hold the appropriate lawn pest control endorsement.

How to Verify

Visit the TDLR license search portal at tdlr.texas.gov and search by company name, individual applicator name, or license number. The search results show the license status (active, expired, or revoked), the license categories held, and any enforcement actions or complaints. Take 2 minutes to verify before signing a contract. If a company cannot or will not provide their license number, do not hire them.

Additional Verification Steps

• Insurance: Ask for proof of general liability insurance and workers' compensation coverage. If a technician is injured on your property or if treatment causes property damage, insurance protects you.
• Reviews: Check Google, Yelp, and the Better Business Bureau for customer reviews and complaint history. Look for patterns in complaints (missed appointments, ineffective treatment, billing issues) rather than isolated negative reviews.
• Written estimates: Get a written estimate that specifies exactly which services are included, the products being used, the price, and the warranty or guarantee terms. Verbal quotes are not enforceable.
• Service guarantee: Ask what happens if pests return between scheduled visits. Reputable companies offer free re-service if pest activity returns between your regular appointments.

Does a Brand-New Dallas Home Need Pre-Move-In Pest Control?

Yes. Many new homeowners assume a brand-new home is pest-free, but new construction in the Dallas metro area carries its own set of pest risks.

Construction Displaces Existing Pest Populations

When builders clear and grade land for new developments in Frisco, Prosper, Celina, McKinney, Anna, and other rapidly growing DFW suburbs, they disturb established fire ant colonies and termite populations in the soil. These pests do not leave the area. They redistribute into the nearest available shelter, which often includes the homes being built on their former habitat. New developments in areas that were previously farmland or undeveloped prairie can have intense fire ant pressure in the first few years after construction.

Construction Gaps and Debris

New homes frequently have gaps at utility penetrations (electrical, plumbing, AC lines), around windows and doors, at the slab-wall junction, and where different building materials meet. These gaps are within code requirements but are large enough for insects and occasionally rodents to enter. Additionally, construction debris (wood scraps, cardboard, drywall pieces, foam) is sometimes left in wall voids, under the slab, or in the garage during construction. This debris can attract termites and provide food and shelter for cockroaches.

Pre-Construction Termite Treatment Has a Lifespan

Most new construction in Texas includes a pre-construction termite treatment: termiticide applied to the soil before the slab is poured. This treatment creates a chemical barrier in the soil beneath and around the foundation. However, the barrier is not permanent. Pre-construction treatments last 5 to 10 years depending on the product used, soil conditions, and whether the barrier was disrupted during construction (plumbing and electrical installations that disturb the treated soil). If you are buying a new-build home, ask the builder which termite pre-treatment product was used and when it was applied. Consider establishing a termite monitoring program (bait stations or annual inspection bond) to provide ongoing protection as the pre-treatment degrades.

What to Request for a New-Build Home

• General pest perimeter treatment to establish a barrier at all exterior entry points
• Inspection of all utility penetrations for gaps that need sealing
• Fire ant yard treatment to address mounds that have established since construction
• Documentation of the pre-construction termite treatment from the builder, including product name, application date, and warranty terms
• Rodent exclusion assessment of the garage, attic access, and roofline

When Is the Best Time to Schedule Pre-Move-In Treatment in Dallas?

The answer: any time of year. Dallas has year-round pest pressure, and there is no season where pre-move-in treatment is unnecessary. The specific treatment emphasis shifts seasonally (more focus on mosquitoes and fire ants in summer, more focus on rodent exclusion in fall and winter), but the core services (general pest treatment, termite inspection, and rodent assessment) are valuable in every season.

Schedule the treatment 3 to 7 days before your move-in date to allow products to dry and settle before you bring in furniture, food, and family.
