You need a SquirrelBuchet, the launch may not kill them but the landing should.

My brother built a rat killing bucket. It’s on line. A neighbor told him anti-freeze as the liquid is better as it won’t freeze out in the shed during winter. Dowel at the top of the bucket with peanut butter smeared on. Ramp up to the top of the bucket. Rat takes a leap to the peanut butter, dowel spins and rat falls to bottom of bucket and can’t get out.

Out in the woods though I imagine all sorts of other good critters might get trapped though.
