Bats like it where it is dark, how about some bright lights?

Concerning the use of an air rifle. Our first house had a rough, unfinished basement and we had mouse problems that I tried to fix with a pellet gun. The difficulty was that if you wounded one (the vitals on a mouse are a small target) and he ran off and died somewhere, it really stunk-up the house. Newlywed wife was not impressed with that house at all.
