For rats, gophers, chipmunks and ground squirrels. Big Snap-E is the end of the round. Special polystyrene material resists rodent-repelling stain and odor as well as bacteria and disease common in old-fashioned wooden traps. Extra-large trip paddle and 90 degree strike bar. Shorter strike distance doubles response speed. Rodents have no escape time and once caught, they stay caught. Sanitary disposal and easy cleaning for years of use.
