Lots of fun stuff regarding tree rats on the internet and you tube. I like to catch them in my 'Hav-a-hart', spend some 'quality time' with them and then turn them loose. Prefer 'open air' targets. There is one that 'bolts' down the fence and avoids our yard. Bit of an ingrate, sneaks into the trap to snack on the peanuts. I do have a solution but will wait until I need the exercise to open the trap.
