Because gopher tunnels can be as deep as 5-6 feet, it is often more difficult to exclude gophers than it is to exclude moles. Physical controls such as barriers, and trapping are useful as direct physical control measures. Barriers such as inch mesh fencing will exclude gophers from a small area. The fence must be deeply trenched into the ground to be effective. This is not likely to be practical on playgrounds or sports fields because of the considerable labor and cost involved.
Trapping is a very effective means of reducing gopher problems.
You will need at least two traps. Macabee or Victor Easy Set spring traps are recommended. Instructions are included with the trap and must be followed explicitly. Box-type traps are more difficult to use. Locate one of the main burrows and excavate an area near the lateral tunnel.
