Identify and stop gophers from girdling roots and killing established trees, shrubs, and ornamentals from below.
Gophers chewing through irrigation, drip systems, and tunneling near foundations.
Find and fix underground drip and soaker lines destroyed by gopher gnawing, and stop repeat damage.
Find and fix chewed drip emitters, pop-up heads, and shallow irrigation fittings that gophers gnaw through repeatedly.
Reduce burrowing pressure that can undermine soil support near slabs, walkways, and hardscape.
Special circumstances — new yards, pets in the picture, or a gopher problem that crosses property lines.
Install the right barriers and defenses before you landscape so gophers never get a foothold in the first place.
Run an effective gopher control program without putting your dogs, cats, or backyard wildlife at risk.
Coordinate control plans across property lines to reduce recurring infestations and tension.
Head to The Playbook for step-by-step control methods, or Quick Start if you want Mark's exact field process.
Look for wet spots with no surface watering source, dry dead zones despite irrigation running, or low pressure in specific zones. Pull up emitters near the damage — chew marks on the line or cut drip tubing confirms gophers.
Direct structural damage is rare, but tunneling near footings can cause soil subsidence and settlement over time. The bigger risk is undermined slabs, retaining walls, or landscaped slopes where soil movement matters.
Underground gopher mesh (hardware cloth, minimum ½-inch opening) installed 18–24 inches deep under beds is the most permanent solution. Above-ground fencing alone won't help since gophers enter entirely from below.
With proper trap placement in the main run, catches typically happen within 24–48 hours. No new mounds for 5–7 consecutive days is a good monitoring signal the gopher is gone — not proof, since a gopher can sit quiet underground for a few days without pushing fresh soil. If mounds resume, it's active again.
