They are really smart.... or can be. I was trying to trap one river rat I named Rambo in the boat shed most of last summer/fall. Tried the big glue boards but he'd get off of it by squeezing between a couple deck boards. Tried a screened box trap but caught a skunk instead....... Thats why I build short box traps.
Seen Rambo out in the middle of the shed floor but before I could get off a shot he jumped straight thru a metal screened window...... 4' up the side wall.
So be careful looking out that screen!
Until I see signs of him again, now that we are ready for our first lawn mowing my time will be spent on that never ending battle vs ground moles....
Good luck in your battle. I look forward to seeing your 'Game' pole.
