What did you bait the havahart trap with? I use peanut butter for the ground squirrels here in NM, works pretty good.
Once they’re in the trap you can’t miss. ;)
I used peanuts, peanut butter, cheetos, and steel cut oats. They managed to roll the thing around to get to the peanuts, oats, and cheetos. Nada on the peanut butter.
