I do not like them either. We had one get into our house and my husband killed it with a frypan. I couldn't ever bring myself to use it even after it had been washed multiple times. We had a guy come out, he has a business in which he calls himself Da Batman and he inspected our house. Luckily he found no sign of any bats in our house and sealed up a few areas that he thought might be problematic. He said since our neighbor across the street has a lot of pine trees it was likely that the bat came from there. I think he was right because a couple months later I was sitting on my screened in porch at about 11am a bat came flying from those trees and flew into the screen of my porch, fell to the ground, then flew back to the neighbor's pine trees. I was so freaked out, I was sure it had rabies since it was out in the middle of the day. Anyway, now I keep mothballs around my porch because apparently the mothballs repel them. I know bats are good but they can be good away from me. I won't be looking up in Pirates or that area anymore.
