With the BIG SNAP-E, it's the end of the road for rats, gophers, chipmunks, ground squirrels and other pesky rodents. The quick response time makes certain that once caught, the rodent stays caught! Two pre-formed holes in the trap base allow for surface mounting. Fingers never touch the rodent. The SNAP-E MOUSETRAP and BIG SNAP-E RAT TRAP are made of durable polystyrene and steel. They both resist stains and odors common in old-fashioned wooden traps, are easy to clean and can be reused for years of service. They are simple, safe and sanitary.
