Rasta, In the summer, in my rural home, ladies would cover their heads, when bats swoop to catch the mosquitoes that the carbon dioxide of your body attracts.
I have an old home, the wood that bats are attracted to, like old barns, the wood is 100+ years old.
When I replaced windows, I had to go around and manually gather the bats and put them out before the new window. That was 2008. I bought a bat hotel for them. Never saw one since. One year, all our #bats disappeared.
