Coil Spring Traps are foot-hold restraining devices used to catch and hold wild animals. These devices have been used for over a century as a cost effective and efficient tool for managing wildlife populations. Coil Spring Traps are manufactured from steel components and powered by a set of compact coil springs. If you are just looking to get rid of a few nuisance varmints or are trying for serious predator control, these traps are up to the job. The double jaw was designed to make it more difficult for animals to escape.
