Rodent Exterminator Cost in Denver, CO (2026)

Last updated: March 7, 2026

By James — 25-year pest control industry veteran

Rodent exterminator cost in Denver ranges from $145 to $570, with the average homeowner paying around $300. Mouse removal costs $145 to $285, while rat extermination runs $285 to $570. Denver's altitude and harsh winters drive mice indoors aggressively each fall, making rodent control one of the most common pest services in the metro area. Deer mice in the Colorado foothills also pose a serious hantavirus risk that requires careful handling.

This guide covers rodent control pricing specific to the Denver metro, including the unique hantavirus risk from deer mice, seasonal invasion patterns, and what drives costs in the area.

Denver Rodent Control Costs by Service

Denver pricing runs close to national averages (roughly 5% below) for most rodent services. Attic cleanup and sanitization can cost significantly more in cases involving deer mice due to hantavirus decontamination protocols.

Rodent Species in the Denver Area

Several rodent species affect Denver homeowners, each requiring a different approach to control.

• House mice. The most common indoor rodent in the Denver metro. House mice are small (2 to 4 inches, uniformly gray-brown), prolific breeders, and enter homes through gaps as small as a dime. They are found throughout the metro in all types of construction.
• Deer mice. Found in foothills communities, areas bordering open space, and mountain-adjacent neighborhoods. Deer mice are bicolored (brown on top, white belly) and are the primary carrier of hantavirus in Colorado. Properties in Evergreen, Golden, Morrison, and the western suburbs are at elevated risk.
• Norway rats. Present in older Denver neighborhoods, particularly Capitol Hill, Park Hill, Baker, and areas with aging infrastructure. Norway rats are ground-dwelling burrowers and are larger than mice (up to 10 inches, not including tail).
• Voles. Common in Denver yards and lawns. Voles create surface runway systems in grass and cause significant damage to landscaping, especially visible in spring after snowmelt. Vole control is typically handled separately from indoor rodent service.

Deer Mice and Hantavirus Risk

Deer mice in Colorado carry hantavirus, which causes Hantavirus Pulmonary Syndrome (HPS). This is a serious and sometimes fatal respiratory illness. Colorado has reported more hantavirus cases than most states, and the Denver foothills are a known risk area.

Hantavirus spreads through airborne particles from dried deer mouse urine, droppings, and nesting materials. Homeowners should never sweep, vacuum, or dry-dust areas contaminated with deer mouse droppings. Instead, the area should be wetted with a bleach solution (1 part bleach to 10 parts water) before cleanup, and a respirator should be worn.

Professional cleanup of a deer mouse infestation costs more than a standard mouse job because of decontamination requirements. Attic cleanup involving deer mouse contamination runs $500 to $2,500, depending on the extent of the contamination and whether insulation replacement is needed. Homes in Evergreen, Golden, Morrison, Conifer, and other foothills communities should treat any mouse sighting as a potential hantavirus risk and call a professional rather than attempting DIY cleanup.

Treatment Methods

Trapping

Snap traps are the primary method for interior rodent control in Denver. Professional trapping programs cost $145 to $285 for mice and $285 to $570 for rats, covering the initial inspection, trap placement, and two to three follow-up visits over two weeks. Interior trapping is preferred over poison bait indoors because it avoids the risk of rodents dying inside walls and causing odor problems.

Exclusion

Exclusion (sealing entry points) is the most important step for long-term rodent control in Denver. Without it, new mice enter the home as soon as the current population is trapped out. Professional exclusion costs $475 to $1,425 and includes:

• Sealing gaps around utility penetrations (gas, water, electrical)
• Installing hardware cloth or metal screening over foundation vents
• Filling gaps in the foundation with concrete, metal mesh, or copper wool
• Replacing worn door sweeps and weather stripping
• Capping open pipe and conduit entries

Mice can squeeze through a gap the size of a dime, and rats through a quarter-sized opening. Older Denver homes with settling foundations, aging weatherstripping, and multiple utility penetrations often have dozens of potential entry points that need attention.

Sanitization

After the rodent population is eliminated and entry points are sealed, sanitization removes droppings, urine, and nesting materials. This is especially important in attic spaces, where accumulated contamination can pose health risks. Standard attic cleanup runs $500 to $1,500, while full insulation replacement (common after severe infestations) can reach $2,500 or more.

Seasonal Rodent Patterns in Denver

Denver's altitude (5,280 feet) and cold winters create a strong seasonal pattern for rodent invasions.

• Fall (September through November). The peak season for mice entering Denver homes. As temperatures drop below 50 degrees at night, mice seek warmth and food indoors. Most pest control companies see a sharp increase in rodent calls starting in late September.
• Winter (December through March). Mice already inside remain active throughout winter. Denver's average January high is 45 degrees with lows around 16 degrees, keeping mice indoors for months. Rat activity in basements and crawl spaces also peaks during winter.
• Spring (April through May). Vole damage becomes visible as snow melts, revealing surface runway systems and bark damage to trees and shrubs. Indoor mouse activity begins to decline as temperatures warm.
• Summer (June through August). The lowest period for indoor rodent calls. However, deer mice remain active in foothills areas year-round, and open space bordering properties may still see activity.

What Drives Rodent Control Costs in Denver

• Altitude and cold winters. Denver's cold winters drive mice indoors more aggressively and for a longer period than in many other cities. The extended invasion season means more homeowners need service, and severe infestations are common by midwinter if not addressed early.
• Older neighborhoods. Homes in Capitol Hill, Park Hill, Baker, and other established Denver neighborhoods often date from the early 1900s. These homes have more gaps, settling foundations, and aging utility penetrations that provide easy rodent entry. Exclusion work on older homes costs more due to the greater number of entry points.
• Newer construction. Homes in Stapleton (now Central Park), Green Valley Ranch, and other newer developments are generally tighter but can still have gaps around utility entries and garage doors. Newer homes near open space or undeveloped land are particularly vulnerable.
• Proximity to open space and foothills. Properties bordering parks, open space, or the foothills face ongoing rodent pressure from the surrounding habitat. These locations also have higher deer mouse (and hantavirus) risk.
• Infestation severity. A minor mouse problem costs $145 to $285 to resolve. An established rat or mouse infestation requiring trapping, exclusion, and attic cleanup can cost $1,000 or more.
• Deer mouse involvement. If deer mice are identified, cleanup costs increase due to hantavirus decontamination protocols. Professional sanitization with proper PPE is strongly advised rather than DIY cleanup.
