In arid regions, flooding tunnels works better than any repellent. Just 10 minutes of water flow makes them relocate naturally without harm.
@purrfect_home I planted a daffodil border around my vegetable garden - not only beautiful but reduced gopher activity by about 80% this season!
Studies show gophers quickly habituate to consistent ultrasonic frequencies. The most effective devices randomly cycle through different sound patterns.
After wasting $150 on various gadgets, I’ve found the most reliable solution is weekly monitoring and immediately filling any new mounds with gravel. Labor-intensive but effective!
