Bat boxes!

Bat boxes!

Do you have a bat box? My dad has wanted to make a bat box for years to help eat the critters that plague his yard, but he's never gotten around to it (typical). I want to get him one for father's day, so does anyone have recommendations about a particular model or supplier? I live in an apartment without tools, so making my own is kind of out of the question. I was also curious about how you attract bats to the box, and how you prevent nasty things like wasps (they've had issues with carpenter bees out there) or just silly things like squirrels or birds from moving in before the bats can. Thanks!
