Bat Colonies in NC Homes
All NC bat species are federally protected. A colony in your attic creates real problems — accumulated guano causes respiratory health risks including histoplasmosis, strong odors, structural staining, and secondary pest infestations like bat bugs. Bat removal requires exclusion (not trapping), and is prohibited May 1 – July 31.
Signs of a Bat Colony
- Small dark droppings (guano) below gable vents or eaves
- Brown staining at entry points on the roofline
- Squeaking sounds at dusk or dawn
- Bats visible exiting at sunset
- Strong ammonia-like odor in attic or upper floors
How We Remove Bats
We use one-way bat valves that allow bats to exit your home but prevent re-entry. Watch the process in action:
