If you have bats flying around your head while you are watching TV, I would like to suggest that you probably should watch less TV and spend the time repairing your shack.
A properly maintained house will not have bats in the living areas.
I know. We get one or two in the house each season, not a flood of them. But I hate them, none-the-less. Vile creatures.
We live in a 1906 Colonial Foursquare. We are in the process of remodeling/upgrading. I finally have flooring, not just packed dirt, LOL!
One thing at a time. And we don’t watch TV; no time between full-time jobs and self-employment ventures. We’ve planned the work and are now working the plan.
But thanks for worrying about me. :)
