Gopher control requires a combination of methods tailored to the severity of the infestation and the desired effect—removal or repelling. The most effective and commonly recommended methods include mechanical trapping, the application of toxic baits, the use of fumigants, and employing repellents or deterrent plants.
Mechanical Trapping:
Trapping is widely considered one of the best ways to get rid of gophers, especially for small to medium-sized areas. Traps such as the Macabee, Victor, or Easy Set Gopher Trap should be placed in the main tunnel or near the freshest mounds. The traps can be checked after several hours, and should be moved if there’s no activity within 48 hours. This method is highly targeted, effective, and pesticide-free[1][3][5].
Toxic Baits:
Poison baits (usually strychnine-treated grain) are effective for larger infestations. These baits must be placed underground in the main tunnels, never on the surface, to prevent accidental poisoning of non-target animals, pets, or humans. Follow all label instructions and local regulations, since some poisons are restricted or illegal in certain regions[1][7].
Fumigants and Smoke Bombs:
Fumigants, such as smoke bombs or aluminum phosphide tablets, can be used to fill burrows with toxic gases. Block all burrow exits before igniting the bomb and follow all safety precautions, especially regarding proximity to structures and soil moisture to maximize effectiveness. Fumigants are generally less effective than traps but can help control persistent populations[1][5].
Natural and Home Remedies:
Repellents can help deter gophers, though results may vary. Castor oil, either as a liquid spray (mixed with dish soap and water) or in granule form, is one of the most popular natural repellents. It disturbs gophers’ digestive systems, motivating them to leave the area. Peppermint oil, chili powder, and camphor oil-based solutions can also be used around plants and tunnels. Reapply these solutions after rainfall or irrigation for ongoing effectiveness[2][4][6].
- Mix 2 tablespoons of castor oil with 2 tablespoons dish soap, dilute into 1 gallon of water, and spray across affected areas[6].
- Add camphor essential oil for additional deterrence, but use cautiously as it’s very potent[2].
- Castor oil granules can be spread and watered into the soil as a slow-release repellent[4].
Plant-Based Deterrents:
Certain plants such as alliums, daffodils, marigolds, and castor beans are believed to naturally repel gophers. However, be aware that castor bean plants are highly poisonous and may not be suitable where pets or children play[6].
Other Methods:
Scent deterrents (pine disinfectant rags, chili powder, peppermint-soaked cotton balls, and garlic stakes) can be inserted directly into gopher holes. Sound repellents such as radios or wind chimes may annoy gophers but typically provide only short-term relief[4].
Key Considerations:
– Mechanical trapping and poison baits are considered the quickest and most effective professional methods for extensive infestations.
– Repellents and deterrents may help protect specific plants or small areas but are less reliable if gopher pressures are high.
– Always check local regulations before using poisons or certain traps.
– Monitor treated areas for signs of re-infestation and reapply as needed.
