Residents reported finding seven bats in the bedrooms of local homes last week, according to officials in the Animal Control section of the New Canaan Police Department. Five of the bats were located and sent to a lab in Rocky Hill, but two could not be found upon the arrival of a professional, according to Officer Allyson Halm, head of the section. Three of the five bats found tested negative for rabies, and results for the remaining two are pending, she said. The families living in the homes where the bats could not be located for euthanization and testing are going through their rabies vaccines, Halm said. “You don’t know how long the bat’s been in the house,” Halm said.
