re: Getting rid of bats from house

Way back when I was in school, I rented a house in Baton Rouge and we had a small 2 story apartment building next door. Every evening it looked like someone was shoveling bats out of the attic vent on the apartment building. Hundreds of bats would pour out of the louvers and swoop down into my backyard. Unfortunately this was pre-Iphone and I don’t have any videos but it was one of the coolest things I’ve seen. I can’t imagine what the second floor apartments must have smelled like with all the guano that must have been in that attic. Evidently the owner figured out what was going on because all of a sudden it stopped. My FIL owned a house in Roatan where we kept the doors and windows open all of the time. Every night bats would fly in the door, make a few circles around the ceiling (probably 18’-20’) and fly back out. Freaked out my sister-in-law but they were harmless. I have no suggestions for getting rid of the bats other than trying to give them an alternate place to live.

This was an easy fix for us. Bats work on high frequency echo location. We climbed up and sat a speaker up next to the entrance (less than a foot) aiming right at the entrance. Left music playing at a loud but reasonable level of volume for 2 days around the clock. Bats left never came back.
