Irvine has a gopher problem that is structural rather than accidental. The city was planned around continuous landscaped greenbelts, and those greenbelts are irrigated, deeply rooted and almost never disturbed. From a pocket gopher’s point of view that is a permanent, protected habitat running through the middle of every village, with private lawns attached to it on both sides. We control gophers by trapping them. We do not put bait in the ground.
Irvine specifically
The greenbelt is the whole story. In most cities a gopher population is limited by patches of suitable ground with roads and hardscape between them. In Irvine the suitable ground is continuous, deliberately so, and it connects at the village edges to genuine open space in Bommer Canyon, Quail Hill, Shady Canyon and the Turtle Rock ridge. What that means practically is that no Irvine yard bordering a greenbelt is dealing with a self-contained population. It is dealing with resupply.
The second Irvine factor is that a lot of the ground people care about is not theirs to work on. HOA common areas, shared slopes and association-maintained landscaping sit immediately against private lots, and the gophers do not observe the boundary. We work on your property and we will tell you honestly when the source is on the other side of the line, so you can take it to your association with something specific rather than a general complaint.
Where they actually are
A gopher spends its whole life underground and you will almost never see one. What you are locating is the tunnel system, and the mounds only tell you roughly where it runs.
The main runway typically sits six to twelve inches down and follows the softest, best-irrigated ground available, which on an Irvine lot means the lawn, the edge of planter beds and the strip along a drip line. Mounds appear off to the side of that main run rather than on top of it, which is why homeowner traps set into a mound almost never catch anything. We pay particular attention to the fence or wall line where a lot adjoins a greenbelt, a slope or a park, because that is the entry corridor and it is where any barrier work needs to go.
The signs people miss
- Fan-shaped or crescent mounds of finely worked soil with the hole plugged and set off to one side, rather than a clean open hole in the middle. An open hole with no plug usually means ground squirrels, which are common on Irvine slopes and need a different approach.
- Shrubs, roses and young trees dying with no visible cause. Gophers feed on roots from below and the top of the plant is the last thing to show it, so people often replace a plant twice before working out what is happening.
- A line across the lawn that feels soft or gives underfoot. That is a lateral tunnel collapsing, and it traces the runway more reliably than the mounds.
- Irrigation failing repeatedly in one zone. Gophers chew poly line and low-voltage wire routinely, and on drip-irrigated Irvine landscaping the plants often show stress before anyone spots a mound.
How we handle it
The inspection is free and most of it is probing rather than looking. We locate the main runway instead of working from the mounds, because that is the only placement where trapping works reliably, and we establish how many separate systems are active. Gophers are territorial and largely solitary, so four active systems means four animals rather than one very busy one.
From there it is mechanical trapping set into the main run, checked and reset on a schedule until the system stops producing. We backfill and level as we go so you can see at a glance whether new mounding is genuinely new rather than old spoil. On lots backing a greenbelt or slope we will talk through a buried barrier along the affected line, because on those properties a steady rhythm beats a one-time clearance every time.
On bait, and why we do not use it
Most gopher treatment sold in Orange County is bait, usually an anticoagulant or a strychnine product dropped into the tunnel. We do not use it on any job, and in Irvine the case against it is stronger than almost anywhere.
The practical objection first: bait is unreliable, because a gopher that notices a disturbed tunnel simply plugs that section and routes around it, and you have paid for a treatment nobody can verify. The larger objection is what happens after. Irvine is ringed by preserved open space that supports red-tailed hawks, great horned owls, bobcats and coyotes, and a poisoned gopher that surfaces or gets dug up feeds directly into that system. Anticoagulants concentrate as they move up the food chain, and California has tightened restrictions on these products repeatedly for exactly that reason. Trapping gives you a countable result with nothing left in the ground.

Photos are from our own crews on real jobs across Orange County and Los Angeles — never stock. We run these same steps on every Irvine call.
What to expect, honestly
Mechanical trapping only, checked at least once every 24 hours. We do not apply pesticides, rodenticides or bait on any job.
On an interior Irvine lot with no adjoining greenbelt or slope, clearing the active systems usually holds for a long stretch, and that is a genuinely finished job. On a lot backing a greenbelt, park, school field or canyon, the population next door is not going anywhere, and any company promising that one visit ends it permanently is selling you something. What we can do there is clear the property, identify the entry corridor, discuss a barrier, and set a check interval that keeps the lawn and irrigation intact.
We will also be clear about where our work stops. We do not repair irrigation, replace turf or perform landscape construction, and we do not work on HOA common area without the association engaging us directly. We will show you exactly what got chewed and where the source is, so whoever does that work is not guessing.
Gopher pressure across the Irvine villages
Woodbridge, University Park, Northwood and El Camino Real carry the steadiest gopher work in the city, and it follows the greenbelt layout almost exactly. Those villages were designed with landscaped corridors threading between the housing clusters, and every lot that backs onto one of those strips is on the front line. The two Woodbridge lakes and their surrounding turf add to it.
The canyon-edge villages are a different situation. Turtle Rock, Quail Hill, Shady Canyon, Orchard Hills and Portola Springs back onto genuine open space with large resident populations and no boundary at all below ground, so the work there is management rather than eradication and we say so up front. Newer high-density product around the Great Park and Cypress Village sees less of this simply because there is less private turf, though the association slopes and common landscaping in those neighbourhoods generate their own complaints.
Questions we actually get asked
How do I tell gophers from ground squirrels? We have both on our slope.
The hole is the giveaway. Gophers leave a fan or crescent mound of finely worked soil with the opening plugged and off to one side, and you will essentially never see the animal. Ground squirrels leave an open hole about two inches across with no plug, often several close together, and they are visible above ground during the day. On Irvine slopes it is genuinely common to have both, and it matters because the trapping approach and the placement are different for each. Worth identifying properly before anyone sets anything.
The mounds are coming from the HOA greenbelt behind us. What can we actually do?
Two things, and they work together. On your side we clear every active system on the property and, where it makes sense, install a buried barrier along the affected fence or wall line, which is the part that changes your situation regardless of what happens next door. Separately, we will document where the activity is originating so you can take something concrete to your association, since a specific report about a defined stretch of common area gets a very different response than a general complaint. We do not work on common area unless the association engages us for it.
Our drip system keeps failing and plants are dying in the same bed. Gophers?
Likely, and the two symptoms usually have the same cause. Gophers chew poly irrigation line as a matter of routine, and the line runs through the softest, most consistently watered soil on the lot, which is exactly where they want to be. Meanwhile they are feeding on the roots of whatever is planted there, so the plants decline for what looks like a watering problem. If you are seeing repeated line failures and unexplained plant loss in one area, check for mounding anywhere within about twenty feet before you replace anything else.
The rest of what we do in Irvine
Gopher work regularly turns up other things using the same soft ground and the same fence line. These are the Irvine services most commonly paired with it.
Licensed for the work we advertise, and clear about the rest
Wildlife control, structural pest control and construction are three separate licenses in California. Plenty of companies blur that line. We would rather tell you exactly where ours sits.
- Wildlife trapping and exclusion — this is us. Tri County Trappers operates under California Department of Fish and Wildlife Trapping License TP-10188, and every technician on our crew carries their own CDFW trapping license. Not a company license with unlicensed helpers under it. Each one, individually licensed by the State.
- Attic cleanout and decontamination — this is us. Removal, bagging, vacuuming and cleaning of contaminated material. We do not apply pesticides, rodenticides or bait on any job.
- Insulation, wood repair and structural work — not us. Tri County Trappers does not hold a Contractors State License Board license. That work is performed by a licensed contractor. We inspect it, document it and hand over the photographs so nobody starts cold.
- Structural pest control (Branch 2) — not us. If your situation needs it, we say so and point you to a licensed structural pest control operator rather than stretching our own license over it.
General liability, professional liability, workers’ compensation and commercial auto, all current, with limits well above what the State requires of a licensed trapper. Certificates on request, before you let anyone on your roof.
OUR METHOD
No rodenticides. No baits, powders, or treated devices.
We work with live traps and exclusion only — on every job, every time. That eliminates the secondary-poisoning pathway that kills owls, hawks, and the pets that eat poisoned rodents. California Department of Fish and Wildlife Trapping License TP-10188.
What gopher control costs in Irvine
Gopher work runs $200 to $1,200 per property. The lower end is the initial setup, locating the runs and getting traps working on an active system. The upper end covers larger or long established properties and includes the maintained follow up visits, which is what keeps ground clear rather than clearing it once and watching it repopulate.
The inspection is free with no conditions, and there is no trip fee if you decide not to go ahead. We can usually be out the same day. See what all of our work costs, including attic cleanouts, exclusion and trapping.
