Professional gopher and mole treatment includes identifying active tunnel systems, setting specialized traps (Cinch, Macabee, or scissor traps), and monitoring over 2-4 weeks until activity ceases. For large infestations, carbon monoxide (CO) fumigation of burrow systems is highly effective. Gopher exclusion baskets can be installed around valuable plants and trees. Gophers are extremely common in Sacramento's clay soils. This estimate uses NorCal pricing for 2025-2026.

Project Timeline

Survey & tunnel mapping

30-60 minutes

Walk the property, identify fresh mounds and surface tunnels, probe to locate main burrow runs, and estimate the number of active gophers or moles.

Trap setting / CO treatment

30-60 minutes

Set traps in main burrow runs (2 traps per tunnel, one in each direction). Or, for CO treatment, insert the machine hose into the main tunnel and seal surrounding openings.

Monitoring & re-setting

2-4 visits over 2-4 weeks

Check traps every 2-3 days, remove catches, reset or relocate traps as needed. Monitor for new mound activity and treat additional tunnel systems.

Lawn repair & exclusion

30-60 minutes

Flatten mounds, fill tunnels with topsoil, reseed or patch lawn. Install gopher wire baskets around vulnerable plants or trees if requested.

Gopher & Mole Treatment in Mill Valley — FAQ

How much does gopher treatment cost?+

An initial trapping visit costs $150-$300. Most properties need 3-4 follow-up visits ($75-$150 each) over 3-4 weeks. Total treatment for an average yard runs $400-$800. Ongoing monthly maintenance is $75-$125 per visit.

What is the most effective gopher control method?+

Trapping is the most reliable method for residential properties. Carbon monoxide treatment is highly effective for large areas with many tunnels. Bait is effective but poses secondary poisoning risk to pets and predators.

How do I know if I have gophers vs. moles?+

Gophers create fan-shaped dirt mounds and eat plant roots (you'll see dead plants). Moles create volcano-shaped mounds and raised surface ridges — they eat grubs and worms, not plants. Sacramento has far more gophers than moles.

Will gophers come back after treatment?+

Vacant tunnel systems can attract new gophers from neighboring properties. Ongoing monthly monitoring and trapping prevents re-infestation. Gopher wire under new sod or around trees provides long-term exclusion.
