I make these water traps and bait them with peanut butter. They just keep on trapping-I've emptied out multiple drowned catches, refilled the water, the existing peanut butter is still plentiful and intact on the spin can, check it in a few days and do it all over again.:thumbsup:
You can add some antifreeze to the water if it's in cold weather but one must be extra careful as it will kill other animals if they drink it so put the trap where cats, dogs, livestock etc. cannot get to it. The trap will also work well with a dry bucket as the mice cannot jump up and out. Put a little bedding material in the bottom and they will hide and not try too hard to escape. The only downside to a dry bucket is that you then in the end have to deal with live mice. If you are in to catch and release, do the dry bucket.
The yellow bucket was the first one that I made a few years ago, the white bucket trap is the "new and improved" model with a folding ramp for storage, hitch pins to keep the bait can centered, an anti-shifting method to keep the ramp in place on the bucket lip, a couple of different bait can height settings for small/larger rodents, all that good stuff. I've made and sold quite a few of these newer traps.
