Pest Control Cost in Denver, CO (2026 Local Pricing)

Last updated: March 3, 2026

By James — 25-year pest control industry veteran

Pest control in Denver costs $90 to $550 for a one-time visit, with the average homeowner paying about $165. The Denver metro area (2.9 million people) has a semi-arid climate that limits some pest populations compared to humid regions, but mice and rats are a top concern year-round, black widow spiders thrive along the Front Range, and seasonal pests like miller moths and boxelder bugs are unique to Colorado.

This guide covers local pricing for the most common Denver-area pests, seasonal patterns, and tips for choosing a pest control company along the Front Range. For national pricing benchmarks, see our pest control cost guide.

Denver Pest Control Pricing by Service

Denver pest control pricing is at or slightly below national averages. The dry climate reduces pressure from moisture-loving pests like termites and cockroaches, keeping costs lower than in humid regions. Rodent exclusion is the most common higher-cost service in the Denver market.

Common Denver Pests and Treatment Costs

Mice and rats ($200 to $600)

Rodents are the number one pest complaint in the Denver metro. House mice and deer mice enter homes through gaps as small as a quarter-inch, seeking warmth as temperatures drop from October through March. Older neighborhoods in Capitol Hill, Park Hill, Wash Park, Baker, and the Highlands have the highest rodent pressure due to aging construction with numerous entry points. Mice also carry hantavirus in Colorado, making infestations a health concern.

Removal costs $200 to $600 depending on severity. Treatment includes trapping, exclusion (sealing all entry points with steel wool, caulk, and metal flashing), and sanitation recommendations. Deer mice are particularly important to address because of the hantavirus risk associated with their droppings. See our rodent exterminator cost guide.

Black widow spiders ($100 to $300)

Western black widows are common along the Front Range. They build webs in garages, window wells, meter boxes, rock retaining walls, and under outdoor furniture. Black widows are most active from May through October and are frequently found in homes with rock landscaping, which provides ideal harborage.

Treatment costs $100 to $300 and includes perimeter spray, web removal, and dust application in window wells and crawl spaces. Most quarterly pest control plans include black widow treatment. See our spider exterminator cost guide.

Wasps ($100 to $375)

Paper wasps, yellowjackets, and mud daubers are active in Denver from late spring through early fall, with populations peaking in August and September. Yellowjackets are the most aggressive and build nests in the ground, wall voids, and under eaves. Paper wasps build open nests under eaves, deck railings, and porch ceilings.

Nest removal costs $100 to $375 depending on location and size. Ground nests and nests inside wall voids are more difficult and expensive to treat than exposed nests on eaves. Late summer is when wasp populations and aggression are at their highest. See our wasp nest removal cost guide.

Miller moths (no professional treatment needed)

Miller moths (army cutworm moths) are a seasonal phenomenon unique to the Front Range. Each spring, typically from late May through mid-June, millions of moths migrate from the eastern plains to the mountains, passing through the Denver metro. They are attracted to lights and enter homes through any small gap. While a significant nuisance, they do not damage property or pose health risks.

Professional pest control is generally unnecessary for miller moths. The most effective approach is sealing gaps around doors, windows, and foundation vents, and reducing exterior lighting during the migration period. The migration lasts three to four weeks and then stops on its own.

Boxelder bugs (included in general treatment)

Boxelder bugs are a common fall nuisance pest along the Front Range. In September and October, they congregate in large numbers on the south and west sides of buildings, seeking warmth. They enter homes through gaps and can appear indoors in large numbers. While they do not bite or cause structural damage, they stain surfaces when crushed.

Perimeter spray treatment in early fall, before they begin congregating, is the most effective prevention. Most quarterly pest control plans include boxelder bug treatment during the fall visit.

Voles ($150 to $400)

Voles (meadow mice) are a significant yard pest in Denver. They create surface runways through lawns and gardens, damage root systems of trees and shrubs, and girdle bark from young trees during winter. The damage is most visible in spring when snow melts and reveals the runway network.

Treatment costs $150 to $400 and includes trapping, habitat modification (reducing ground cover and mulch depth), and sometimes bait stations. Damage to established trees and landscaping can be costly to repair.

Subterranean termites ($1,000 to $3,000)

Termites exist in the Denver metro but at lower risk levels than humid regions. They are most common in older neighborhoods with irrigated yards, mature trees, and wood-to-soil contact. Areas along the South Platte River corridor and older parts of Aurora, Lakewood, and Arvada see occasional termite activity.

Treatment costs $1,000 to $3,000, below the national average because infestations tend to be smaller and less aggressive. Annual inspections are recommended for older homes and during real estate transactions.

Cost Factors in Denver

• Home age. Older homes in Capitol Hill, Park Hill, Wash Park, and Baker have more gaps and entry points that attract rodents and pests. Newer construction in the suburbs (Stapleton/Central Park, Highlands Ranch, Parker) generally has fewer pest issues.
• Elevation and microclimate. Denver sits at 5,280 feet with a semi-arid climate. The dry conditions reduce moisture-loving pests but create habitat for species adapted to the Front Range. Foothill communities (Golden, Evergreen, Conifer) have different pest pressures than the plains side of the metro.
• Landscaping. Rock landscaping (common in Denver xeriscaping) provides harborage for black widows and other spiders. Irrigated lawns attract voles. Mature trees near homes increase rodent and carpenter ant risk.
• Proximity to open space. Denver has extensive urban open space and trail systems. Homes adjacent to parks, greenbelts, and natural areas face higher wildlife and rodent pressure.
• Construction type. Many Denver homes have unfinished basements with exposed utility penetrations that provide rodent entry points. Sealing these gaps is a key part of effective pest control in the market.

Choosing a Pest Control Company in Denver

• Verify Colorado licensing. Colorado requires pest control operators to be licensed by the Colorado Department of Agriculture. Verify the license before hiring.
• Prioritize rodent exclusion expertise. Since rodents are the top pest concern in Denver, choose a company with strong exclusion (sealing entry points) capabilities, not just trapping. Effective rodent control requires identifying and sealing all entry points.
• Get at least three quotes. Denver has a competitive pest control market with many local and national companies.
• Ask about hantavirus precautions. Deer mice are common in Colorado and carry hantavirus. A good company will take precautions during cleanup (wetting droppings before removal, using respirators) and advise you on safe cleanup practices.
