I had serious (protected!) Brown Bat bat issues at my other farm - 3rd floor walk-up attic, insulated, and then for some reason my ex put plastic up across the insulation and it made a perfect haven for bats, which could get in, in some of the TINY gaps in the eves. One time I had 6 live bats in the house! *SHUDDER* I got very brave, and I never killed a one - just caught them in a towel and tossed them back outside.
When it came time to sell, I spent $12K having the entire attic torn apart, cleaned and sanitized and new insulation blown in on the floor. And did those bats ever return to THANK ME? Nope, LOL!
But, it’s the new owners problem now! Yay!
Growing up I loved bats. Still do as long as they stay out of my home and garage. I grew up in the ‘country’, lots of hills, hollers, etc. (laf, have to say it correctly).
My parents had a street light installed at our driveway. And the bats LOVED it. They would fly around it every evening. My brother and I found throwing rocks straight up in the air they would dive at them like prey. Hey, country kids have to get inventive. They fascinated me. Batman comics helped too(smile).
It is a wonder we never got them in the house or other buildings. Probably because they had an abundance of wonderful caves where we lived. Miss that place.
