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. Your fingers never touch the rodent. Made of durable ABD plastic and steel. They resist staing and odors common in old-fashioned wooden traps, are easy to clean and can be reused for years of service.
