Here is the trap. It's about 1 foot square by 2.5 to 3 feet long.There is no commercial scent or attractant available so what people do is if the catch one they will leave him in the trap a couple days to season it and then transfer him to your other traps so he can season it also. I would guess dragging a dead one through might help also. You can use boards around a hole to guide them into a trap and sets against walls or fences are also good. The key is the scent. A thermal or night vision scope on a 17 or 22 mag or even 223 with varmint bullets does well also. Infrared night vision works pretty well also but for me they are harder to spot with infrared.
