Wow. We had a note sent out a couple of years back asking if we found a dead bat to let them know. Well, found one. Our neighbor had some in a vent to his garage. My son pointed it out. He could hear them! I couldn't! lol, hard of hearing? Anyway, called the city, guy came out, said it had been dead too long to take. Guess they had had some rabies show up somewhere. The guy had the neighbor close off that place so they couldn't get in. He didn't even know, but when he went to work on it, found a lot of bat poop in the garage! .Around here,if a bat is in the house, they recommend shots. If they can catch the bat it depends on the results of testing
