A timely post. We knew we had mice, especially when my daughter would say "look! A mouse!"
I (me only, not my more knowledgeable hubby) decided to get live traps. The kind that traps the mouse, but does not kill it. We placed 4 in the basement. We caught 8 mice over a few days. One of the traps was destroyed by a mouse, chewing his way to freedom.
We took the mice to the Forest Preserve and let them go. It was a busy day at the preserve, so we felt quite stupid driving around for an appropriate place to let them go.
When we got home, we had caught another mouse. Then another one. Unfortunately, when mice are hungry they do what they do. I woke up one morning to the wails of my children- upset because one had "ripped apart and ate" the other.
Since we have 2 mice as pets, we keep the "found" mice in an extra 10 gal aquarium with food and water until we get a few to be released at the forest preserve.
I think a better way is to use "killing" traps. Get rid of them once and for all. This is the season for mice to come in. Seal all cracks, foam up all holes, stick steel wool in any crevice that can't be foamed. Get a cat. Get traps. Good luck!
They are pretty cute, though. :'(
