Gopher Quick Tips by the University of California

Gophers are destructive rodents that burrow underground and feed on plant roots, causing damage to gardens, lawns, and irrigation systems. Early detection is crucial, as indicated by the presence of half-circle mounds with plugged holes. Protect plants with underground fencing or wire baskets. Trapping is an effective control method, using traps placed underground in active burrows. Avoid unproven methods like owl boxes or repellents. Fumigation is ineffective due to gophers' ability to seal off their burrows. It's important to minimize pesticide use to protect waterways.
