Denver's pest control market includes both well-established local companies and national chains, and the quality difference between them is often significant. National franchises bring name recognition and standardized protocols, but frequently lack the deep Colorado-specific knowledge that differentiates genuinely effective treatment from one-size-fits-all programs that underperform against region-specific pest pressures.
Our research team evaluated more than 40 pest control providers serving the Denver metro. We assessed Colorado Department of Agriculture (CDA) licensing, treatment effectiveness documentation, guarantee terms, and specifically examined each company's approach to Colorado's most common and challenging pests: mice, boxelder bugs, bed bugs, black widow spiders, and the species most homeowners aren't prepared for. No company paid to appear here.
How We Evaluated
The Rankings
Whitmore Pest & Wildlife Control
Whitmore Pest & Wildlife Control earns the top spot through a review record that is difficult to argue with — a 4.9-star Google rating across more than 1,700 reviews, sustained by a family-owned team rather than a national franchise. The company holds memberships in the National Pest Management Association, the Colorado Pest Control Association, and the National Wildlife Control Operators Association, a credential stack few Denver competitors can match.
Their scope is another differentiator: alongside conventional pest work — ants, spiders, rodents, bed bugs, wasps — Whitmore handles wildlife removal for bats, raccoons, skunks, snakes, and squirrels, plus the damage repair and disinfecting work that follows an intrusion. Their guarantee is straightforward: if pests linger between visits, they return to re-treat at no additional charge.
EnviroPest
Six decades in the same market is the strongest longevity signal on this list. EnviroPest has operated in Colorado since 1965, and its 4.6-star average across roughly 3,000 reviews reflects sustained performance at a scale most local companies never reach. The company is a member of the National Pest Management Association and the Colorado Pest Control Association, and participates in PestVets of Colorado. Its service menu is among the broadest in the metro — general pest programs, bed bug heat treatment, mosquito and tick control, termite work, wildlife removal, and organic treatment options — delivered from offices in Englewood, Boulder, Loveland, and Colorado Springs.
Colorado Pest Management
Colorado Pest Management has served the Denver area since 1989 as a family-owned, veteran-founded company built around Integrated Pest Management — a methodology that emphasizes inspection, exclusion, and environmental conditions over reflexive chemical treatment. Its scope runs from conventional insect and rodent work through bed bug treatment, sanitation services, and wildlife removal for squirrels, raccoons, and bats, for both residential and commercial clients. A 4.5-star average across roughly 147 aggregated reviews reflects consistent, if lower-volume, customer satisfaction sustained over decades in the same market.
Advantage Pest Management
Advantage Pest Management is a locally owned Denver company whose Google profile — a 5.0-star average across more than 600 reviews — is among the strongest in the metro. The company is a member of the National Pest Management Association and the Colorado Pest Control Association and operates under Colorado Department of Agriculture licensing, backing its work with a satisfaction guarantee that includes complimentary re-treatment. Its service list spans home pest programs, rodent control, mosquito control, and commercial accounts across more than 30 metro communities.
A.P. Pest Control
A.P. Pest Control is a family-owned operation based on Champa Street in central Denver with perfect 5.0-star averages on both Google (235 reviews) and Yelp (56 reviews) — a rare double in a service category where scheduling complaints routinely drag ratings down. Reviewers repeatedly cite direct communication and the absence of subscription upselling. The company handles bed bugs, cockroaches, rodents, ants, fleas, and stinging insects across more than 28 Colorado cities, backed by a written satisfaction guarantee.
Bee Smart Pest Control
Bee Smart Pest Control has served the north metro corridor for more than two decades from its Brighton base, earning a 4.9-star Google rating across 200+ reviews. Its coverage — Thornton, Westminster, Commerce City, Broomfield, Northglenn, and Boulder County — fills territory that many Denver-central companies treat as an afterthought. The licensed and insured team emphasizes assigning familiar technicians to repeat accounts, and its service menu covers the region's staples: ants, wasps, spiders, mice and rats, bed bugs, and mosquitoes.
Think Pest Control
Think Pest Control is a family-owned Highlands Ranch company drawing on roughly 20 years of industry experience, with a 4.9-star Google rating across 200+ reviews to show for it. Its programs cover the south metro's common pressures — ants, spiders, rodents, roaches, bed bugs, wasps, and mosquitoes — using EPA-approved products, and its satisfaction guarantee includes free return visits if pests reappear between treatments. Coverage centers on Highlands Ranch, Littleton, Lakewood, Aurora, and Castle Rock.
Environmental Pest Control Inc
Environmental Pest Control Inc earns its place through bed bug treatment depth that few metro companies match — heat, steam, and Cryonite (carbon dioxide freezing) options alongside conventional methods, letting the treatment fit the infestation rather than the other way around. The locally owned company, based on West Colfax in Denver, holds a 5.0-star Google rating across roughly 145 reviews and backs its work with a satisfaction guarantee. Its listed coverage spans more than 40 metro cities for both residential and commercial clients.
Side by Side Pest Control
Side by Side Pest Control has built a 5.0-star Google rating across roughly 320 reviews serving the northwest metro — NW Denver, Wheat Ridge, Golden, Arvada, and Westminster. Its scope is unusually broad for a company its size: general pest and rodent work plus wildlife control for raccoons, birds, and snakes, along with mosquito and weed services, for residential and commercial clients. Membership in the National Wildlife Control Operators Association supports the wildlife side of the practice.
OBEX Pest Defense
OBEX Pest Defense rounds out this list as a locally owned Front Range company that has accumulated more than 300 reviews across Google, Thumbtack, and Angi, and ranks among the most-hired pest control companies in the state on Thumbtack. Its approach centers on personalized treatment plans built for the specific pest rather than a standardized route service — a fit for homeowners dealing with a defined problem such as wasps, rodents, or spiders. Coverage extends from Denver proper through Littleton, Aurora, and the eastern metro.
Frequently Asked Questions: Pest Control in Denver
What pests are most common in Denver homes?
Denver's most common household pests include mice and voles (particularly in fall and winter when temperatures drop), boxelder bugs (appearing in large numbers in late summer and early fall), earwigs, spiders (including black widows in older neighborhoods and garages), odorous house ants, and bed bugs (increasing significantly across all Denver metro zip codes over the past five years). The western Denver metro and foothills communities also encounter scorpions. Wasps and hornets are a reliable summer concern throughout the metro.
How much does pest control cost in Denver?
Pest control pricing in Denver varies by service type. A single general pest treatment runs $100 to $250. Annual protection plans (4 to 6 visits per year) range from $400 to $800 for a typical home. Bed bug treatment for a single room runs $300 to $600; whole-home heat treatment typically costs $1,200 to $3,000. Termite treatment runs $500 to $2,500 depending on treatment method. Wildlife removal starts at $150 and can reach $800+ for complex exclusion projects. Always get written quotes that include the specific treatment plan and products to be used.
Are termites common in Denver?
Termites are less prevalent in Denver than in humid southeastern states, but subterranean termites (Reticulitermes hesperus) do exist in the metro area — particularly in older neighborhoods with wood-to-soil contact or irrigation-heavy landscaping that keeps soil moisture elevated. Many Denver homeowners are surprised to learn they're at risk. A professional inspection is advisable when purchasing an older home or when unexplained wood damage appears, especially in basements or crawlspaces.
What should I ask a Denver pest control company before hiring?
Ask for a specific treatment plan — what pesticides will be used, how they'll be applied, and the expected timeline for results. Verify that the technician holds a Colorado Department of Agriculture (CDA) pest control applicator license. Inquire about pet and child safety protocols during and after treatment. Ask specifically about re-treatment guarantees — reputable companies provide written commitment to return at no charge if treatment is ineffective within a specified period, typically 30 to 90 days. Avoid companies that can't provide a written treatment plan before starting work.
How to Use This List
Every company here holds current Colorado pest control licensing and demonstrated genuine effectiveness in our evaluation. The right provider depends on your specific pest issue: bed bug heat treatment requires different expertise than general pest prevention, and wildlife exclusion is a specialty distinct from conventional extermination. Use the strength pills and service area notes to identify the best match for your situation, then request written treatment plans and guarantee terms before committing.
