Gopher Control: Effective Strategies for Protecting Your Yard

Understanding the Enemy

Pocket gophers move up to 50 tons of soil per acre per year. They live 2–5 years, produce two litters annually of 4–10 young, and can quickly turn a lawn into a minefield.

Control Options

Exclusion

Wire mesh (½-inch hardware cloth) lining raised beds and tree planting holes is the only permanent barrier. For a whole yard, the cost is prohibitive; focus on high-value areas like vegetable beds and young trees.

Trapping

Box traps (e.g., Macabee, Gophinator) placed in active tunnels are highly effective. Check daily. This method avoids chemicals and lets you confirm kills.

Baiting

Poison baits (strychnine, zinc phosphide) applied deep in tunnels work but pose risks to pets, wildlife, and children. Follow label directions meticulously.

Repellents and Predators

Castor oil-based repellents offer temporary relief. Encouraging natural predators—barn owls, snakes, cats—helps but rarely eliminates an established population.

What Not to Do

Flooding tunnels, using gasoline, or explosive devices are dangerous, often illegal, and can damage foundations or contaminate soil.

Integrated Approach

Combine trapping in active zones with exclusion around prized plants. Monitor regularly; gophers reinvade from neighboring properties.
