re: Rat in my Shop

Get a large victor rat trap.

1 nail it to piece of plywood about 1' square.

Where the snap comes down, nail some finishing nails around the perimeter about 1/2" apart and trim them down about 3/8"

Bait trap with peanut butter under the trigger.

Put it up against a wall.

I don't have rats but my Uncle has an outdoor shed next to a cane field and that's how he gets them. It also works to catch squirrels.
