Many of us have times we need a double door trap to catch an animal on the spot that is trapped in a basement or attic. Pan traps can sometimes be problematic, too slow and an animal can pass through them without firing the trap. With the wire trigger, animals have a hard time passing through the trap without firing it. When it does fire, animals won’t be able to beat a fast closing power door.
Jerry got a “rat” call that turned out to be a duck in the attic, of all places, a first I would guess. He simply made a positive set and ran the duck into the cage. I did the same thing with a fox in a basement a couple of years ago.
