Deter gophers by using scent repellents such as smoke, mulch, or a homemade mixture of castor oil and water. Purchase smokers and mulch at hardware, home improvement and gardening stores.
Attracting predators to your property can also be an effective remedy for gopher infestations. To attract owls, build or purchase a nest box, and nail it to a tall tree or the outside of a barn. Line the interior of the box with straw, and wait for owls to find it.
Hardware, home improvement and gardening stores also carry commercial gopher repellents, scissor traps and rodent poison. Scissor traps and poison are lethal to gophers, and poison can be dangerous to local ecosystems if used incorrectly. These methods are not legal in all locations.
