We keep live traps baited with rodent block and peanut butter. These things are cool they have a little ramp that the rodent walks up and their weight pushes the ramp down giving them access to the area where the bait is, they have to step off of the ramp to get to the bait and when they do it goes back up blocking off the way out! No harm whatsoever to the rodent and you can return them to their tub or feed them. No harm and no wasted feeder!
Call your local exterminator and ask for them I got them from my best friend who works for a local exterminator.
Well if I catch these lil Houdinies (LOL)...I thought it wouldnt be safe to feed them or place them back in their cage?
