My house is overrun with mice. I enjoy a 4 month old little one, so I don't want any poison in the house. So, I hold a trap line! Any considerate hints? (Bait, types of traps?)
How much be your gas bill?
Answers:    yes, the old fad spring loader with some peanut butter works greatly well, but net shure that all the traps a close to a wall or something, mice don't see extraordinarily well and use their whiskers to narrate where to stir, and they rub them on the wall to know when to turn!
Do you similar to craigslist?
An old fashioned spring trap bait with peanut butter works every time.
