foolproof rat and mouse killing device:
Parts list:
2 or 3 gallon plastic bucket from hardware store, a couple bucks.
wire coat hangar, cheap to free
35MM film canister, may be hard to find that in the digital age
drill or melt 1/4" holes through bucket on opposite sides near top.
straighten out enough coat hangar to go through those holes and beyond a few inches either side.
Insert wire through bucket, through the cap and end of film canister, and out the other hole in bucket. you may need to use an icepick or small drill bit on the canister, but the idea is a tight fit. Center it in bucket.
Now you have a film canister fixed to a wire that spins freely in the top of a bucket.
Smear a coat of peanut butter on canister. add 3" of water to bucket. make a ramp or two out of sticks, boards, or stuff leading up there. To expidite the process, put a couple smears of peanut butter on ramps if you wish. It is not really necessary.
Place this in any secured place the pets can't get to. the device is harmless, but the dead rats/mice might not be.
I have used this a few times over the years, and it works perfectly. The mice keep coming, trying to get PB, falling off the spool and into the water and drowning. it does not need reset, and it will clear out a whole colony of mice in one evening.
Dump in the toilet for easy cleanup.
