Instructions are usually provided by the manufacturer. When trapping, find the main tunnel as described under Hand Baiting . You may have to experiment with trap type and placement. Traps should be attached to a stake with a wire or chain. Fasten each trap to a stake by means of a wire or chain.
Trapping is most effective when gophers are pushing up new mounds, generally in spring and fall.
If a trap is not visited within two days, move it to a new location. In spring and early summer when gophers are mating or when young may be present, it is a good idea to reset traps in the same location after the first gopher is caught. A few materials and devices are registered for fumigating gopher burrows. A large volume is needed to fully flood a pocket gopher tunnel system. In addition, fumigants diffuse into soils, particularly when soils are dry or sandy.
