Sinsull, the bats will be ABOVE you -- in between the ceiling and the roof. You may hear them coming home (with hobnailed boots and talking to each other about the night's adventures) around dawn, but you probably won't see them or have them sharing the guest room with you. (In July the adolescents sometimes get lost and find themselves inside the house -- and sometimes need assistance getting outside again. Sigh. I plugged up their entry just below the roof's peak on the front side of the house, but the ladder doesn't reach in the back.)

Besides, the bats in the pants were in my employ (I paid them off in mosquitoes) -- I was trying to encourage what seemed like a permanent lodger (again!) to find an apartment. (Gee. Now you know why I don't have kids!)
