Homes nestling in the Colorado foothills and Rocky Mountain valleys provide beautiful scenery, but their rustic rooflines and elevated structures also offer prime roosting habitat for local wildlife. At Colorado Pest Management, we frequently assist foothill property owners dealing with unwanted attic guests, particularly bats and squirrels. Resolving an attic infestation requires a humane, systematic approach that protects both your home and native wildlife populations.
Recognizing the Signs of a Bat Roost
Bats can squeeze through exterior gaps as tiny as 3/8 of an inch, often entering near ridge vents, soffits, and fascia boards. Property owners usually notice scratching or squeaking noises coming from the ceiling at dusk and dawn. Outside, dark oily rub marks around roof entry points and accumulations of guano (bat droppings) along attic insulation or upper siding are clear indicators of an active colony.
The Dangers of Guano Accumulation
While bats are ecologically vital for controlling local mosquito and moth populations, sharing your living space with them poses serious health risks. Bat guano harbors Histoplasma capsulatum, a fungus whose airborne spores can cause respiratory infections in humans when disturbed. Furthermore, guano buildup damages attic insulation and attracts secondary pests like bat bugs, carpet beetles, and dermestid beetles into your ceiling structure.
Understanding Colorado Bat Regulations & Maternity Seasons
In Colorado, bats are protected wildlife species, making it illegal to poison, trap, or harm them. Additionally, humane bat removal requires strict adherence to seasonal timing. Professional exclusion cannot take place during the summer maternity season (typically mid-April through August), when flightless pups are nursed inside roosts. Attempting DIY removal during this window risks trapping flightless young inside, leading to severe odor issues and regulatory fines.
Professional Exclusion Devices and Permanent Repairs
Effective bat control relies on one-way exclusion valves installed over main roof entry points. These specialized devices allow bats to safely leave the attic at night to feed while preventing their return. Once all bats have safely departed, technicians seal every secondary vulnerability around your roofline using heavy-gauge galvanized steel mesh, outdoor silicone sealant, and custom metal flashing.
Protect Your Mountain Property Humanely
Clearing wildlife from an attic requires specialized height equipment, biological safety precautions, and deep knowledge of local wildlife laws.
