Dean found a bat house at the local Bethesda. We have a book about building bat houses, and the intention to (someday) build one but this was too good to pass up.
The slots underneath allow the bats to enter and exit the house.
I like bats, a natural mosquito predator. If they will eat mosquitoes I will pay their rent. Is it so wrong to think this might mean more than 1 minute in the garden without the slide/whack/slide/whack?
Now if only the ticks would go away. Five found so far (two attached), including more deer ticks than usual. I hear they're going to be bad this year.
