They definitely don't get tangled in your hair! We once had a very lost and confused bat in our bedroom and it flew into the back of my head, but no tanglinganyone else terrified of the thing about bats getting trapped in your hair and never able to get out? not even sure if this is real (and I literally always have mine in a bun so irrelevant anyway..) but still a weird fear
We also live near a country park with a little bridge over a lake, we stood on the bridge at dusk and there were hundreds of bats all around us swooping and hunting the bugs over the water, they do get close to you but not that close!
ETA I am in the UK so these are fairly small! I appreciate elsewhere in the world there are much bigger but frankly I love them all
