Bats Control
in Boulder.
Professional bats treatment across Boulder. Humane bat removal + guano cleanup, compliant with Colorado wildlife regs.

Bats are a recurring concern across the Denver Metro Area, and Boulder is no exception. Boulder is wedged against the foothills with the city's western boundary effectively up against open space and protected wildland. Boulder Creek, Wonderland Lake, and the extensive open-space ring create constant wildlife corridors into residential blocks. Bats love attics, soffit cavities, chimney voids, and any warm dark protected space they can enter through a 1/2-inch gap. They especially favor older homes with heavy soffit detail and chimney flashing irregularities.
Front Range bat populations migrate in spring and seek roosts in early summer. Older Denver homes with original soffit and fascia construction are highest risk; newer homes with damaged soffit screening can also become roost sites. In Boulder specifically, foothill proximity drives intense rodent, squirrel, raccoon, and bear pressure. student rental concentration near cu drives bed bugs and roaches. environmentally-conscious clientele expects eco-first methods. older hill homes with original construction face heavy carpenter ant and overwintering pest pressure. compounds the picture — meaning Boulder homes face bats pressure that's distinct from the metro average.
EPC has run bats jobs across every corner of Boulder. Boulder housing is a mix of expensive foothill-adjacent estates, dense student rental housing near CU, and older Hill and Mapleton neighborhoods with original 1900s construction. Student rentals see disproportionate bed bug and cockroach pressure due to high turnover and shared housing. Our approach is humane bat removal + guano cleanup, compliant with colorado wildlife regs.
How EPC Treats Bats in Boulder
Inspection and Entry-Point Mapping
Tech identifies primary and secondary entry points (often pencil-sized gaps in soffit corners, around chimney flashing, or where roof meets wall). Bats use openings as small as 1/2 inch.
One-Way Valve Installation
Specialized check valves installed at active entry points. Bats exit normally to feed; they can't re-enter. After 5–7 days, the roost is empty.
Final Sealing
Once the roost is confirmed empty, our exclusion experts will provide an estimate for sealing all primary and secondary openings with hardware cloth, foam, and exterior-grade sealant.
Guano Cleanup + Decontamination
Attic guano removed (HEPA-filtered respirators required), insulation replaced if soaked, and surfaces decontaminated. Critical for indoor air quality and histoplasmosis risk reduction.
Signs of Bats in Boulder Homes
- Bats observed entering or exiting the home at dusk/dawn
- Brown staining around small roof or soffit openings (oil from bat fur)
- Strong ammonia odor in attic (guano accumulation)
- Black pellet droppings on walls below roost entry points
- Squeaking or rustling sounds in attic at dusk and dawn
- Bats found indoors (a single bat in a bedroom is a rabies-exposure event — call us immediately)
Bats Prevention for Boulder Properties
- Annual roof and soffit inspection — catch openings before bats find them
- Cap chimneys and seal flashing gaps, especially around dormer junctions
- Maintain attic vents with proper screening (1/4-inch hardware cloth)
- Exterior porch lights attract insects which attract bats — switch to yellow LEDs
- Don't disturb a roost yourself — removal timing matters legally and biologically
Bats in Boulder — Frequently Asked Questions
How much does bats treatment cost in Boulder, CO?

Is bats treatment in Boulder guaranteed?
Yes. If bats return inside your service window, the re-service is free of charge — it is built into the original quote rather than sold as an add-on. Any follow-up visits the treatment plan calls for are included in the price you were quoted up front.
Why do Boulder homes get bats?
Foothill proximity drives intense rodent, squirrel, raccoon, and bear pressure. Student rental concentration near CU drives bed bugs and roaches. Bats love attics, soffit cavities, chimney voids, and any warm dark protected space they can enter through a 1/2-inch gap. They especially favor older homes with heavy soffit detail and chimney flashing irregularities.
What are the first signs of bats in a Boulder home?
The earliest indicators are: bats observed entering or exiting the home at dusk/dawn; brown staining around small roof or soffit openings (oil from bat fur); strong ammonia odor in attic (guano accumulation). Catching any one of these early usually means a smaller, cheaper job than waiting until the problem is obvious.
Do you serve my part of Boulder?
Yes — Environmental Pest Control covers all of Boulder (80301, 80302, 80303, 80304, 80305) plus 200+ Colorado ZIP codes across the Denver metro and Front Range. We have been locally owned and operated since 1985 — not a franchise.
Are bats dangerous?
Health risk is low but real: rabies (rare but fatal if untreated), and histoplasmosis from old guano accumulation. The bigger concern is the structural and air-quality damage from prolonged occupancy.
Can I just remove the bats myself?
Legally restricted in Colorado, especially during maternity season. Premature sealing strands flightless pups inside walls — they die, smell, and stain. Hire a wildlife pro.
