Q. If a bat gets into my house, is it legal to remove it myself or kill it?
A. Bats that enter a home but are not roosting in it usually will exit on their own if homeowners close off exits to keep the bat in a single room and keep windows open overnight. The Illinois Department of Natural Resources recommends hiring a professional bat removal service to capture and remove bats found permanently roosting in a home. By state law, property owners or tenants must file for a nuisance animal removal permit to trap and remove most species of wildlife that take up residence in a building. As for killing a bat: In Illinois, it is unlawful to harm or kill a bat. All 12 species of bats are protected by Illinois state wildlife code.
