Bat Colony Removal Newcastle, WY
Wyoming's bat removal specialist. Humane one-way exclusion, full property inspection, and a written warranty on every exclusion we install.

Bat Colony Removal in Newcastle
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 Newcastle and the Northeast Wyoming
Newcastle is the seat of Weston County at 4,317 feet near the South Dakota border, a small city surrounded by the Black Hills ponderosa pine forests and grass-sage open country. The proximity to the Black Hills creates a different bat habitat than most of Wyoming, with forest-roosting species more likely to occur alongside the typical high-plains building bats. Newcastle's older main-street buildings and residential neighborhoods are common sites for bat encounters.
Big brown bats are the primary building species in Newcastle. The Black Hills ponderosa pine habitat nearby supports silver-haired bats and hoary bats that may roost in structures at the forest edge.
What is included
- Full property inspection. We inspect the full structure to locate every entry point before any work begins. No guesswork, no missed openings.
- Custom one-way devices. Each exclusion device is custom-fitted to the specific opening. Bats exit naturally but cannot re-enter.
- 5 to 10 day vacate window. Once devices are installed, the colony clears the building within 5 to 10 days under normal conditions.
- Written warranty. If bats re-enter through any point we sealed, we return at no charge. Every exclusion is warranted.
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.
