I'm stupidly terrified of spiders, so I understand people's fear of bats, but really they're very sweet. A tiny little pipstrelle (size of a baby mouse) was caught in the net curtain of my bedroom window one night. The poor wee thing was so cute. They're supposed to emit supersonic sounds but I could hear small squeaks. I gently wrapped it in my dressing gown and put it outside. Here in UK all bats are protected, and you're not even allowed to evict them from your roof space without permission and supervision from the wildlife folk. I've got batboxes in my garden high up on the trees. But I understand in other countries they can be a vector for rabies.
