Bat Colony Removal in Gillette
We install custom one-way exclusion devices at every entry point on the structure. Bats exit naturally but cannot return. The colony vacates in 5 to 10 days depending on size and season. After the colony has left, we remove the devices and seal every opening permanently. No trapping, no poison, no harm to the bats. Every exclusion complies with Wyoming Game and Fish regulations and federal bat protection law.

About Gillette and the Northeast Wyoming
Gillette is the seat of Campbell County and the center of Wyoming's coal and oil production region, with rapid population growth since the 1970s producing a large inventory of suburban ranch homes and commercial buildings. The Belle Fourche River drainage to the north and the rolling sagebrush grasslands surrounding the city provide open foraging corridors for bats that exploit the high insect abundance near stock ponds and irrigation sources. Gillette's continental climate brings cold winters that drive structure-roosting bats to seek attics earlier each fall.
Big brown bats are the predominant building bat in Gillette and surrounding Campbell County. Brazilian free-tailed bats have been documented in the eastern Wyoming lowlands and may form colonies in larger buildings near the city.

Common questions
Why can't I just seal the bats in or use poison?
Sealing bats inside is illegal under Wyoming and federal law. Poison is prohibited for bats entirely. Humane one-way exclusion is the only legal method and the only method that works permanently.
When is the best time to do bat removal in Wyoming?
Spring (March through May) and late summer through fall (August 15 through October) are the two ideal windows in Wyoming. We do not do exclusions during the maternity season when flightless pups are present, roughly June through mid-August, because sealing exits during that period traps juveniles inside.
How long does the process take?
After devices are installed, the colony clears in 5 to 10 days. We then return to remove devices and permanently seal every opening. Total project time is typically one to two weeks depending on colony size and weather.
