The short version
Gopher control requires identifying active burrows, then using traps or bait applied by a professional. For property managers, a combination of trapping, exclusion, and habitat modification is most effective. Expect costs of $150-$700 per treatment, with peak seasons in spring and fall.
- Pocket gophers are solitary and territorial; each tunnel system usually contains one gopher.
- Signs of infestation include fan-shaped mounds, plugged burrow openings, and damaged plant roots or irrigation lines.
- DIY methods like flooding or poison baits are often ineffective or dangerous; professional trapping has the highest success rate.
- Prevention focuses on exclusion barriers (hardware cloth), habitat modification (reducing preferred plants), and regular monitoring.
For property managers, homeowners' association boards, and commercial landscapers who need a reliable, cost-effective plan to manage gopher populations across multiple acres or dozens of properties. Whether you're overseeing a residential community, a golf course, or a corporate campus, the principles here apply—but the scale demands a systematic approach.
What to look for
They are active year-round, but their digging peaks in spring and fall when soil moisture makes tunneling easier. Their burrows can be 6 to 12 inches below ground, with lateral tunnels radiating from a main chamber. Gophers belong to the Geomyidae family and are found throughout the western and central United States, with species like the Botta’s pocket gopher in California and the plains pocket gopher in the Great Plains.
- 1Fan-shaped mounds of loose soil (usually 6-12 inches in diameter) with a plugged hole off to one side.
- 2Plugged burrow openings (the dirt plug is visible but not mounded).
- 3Wilting or dying plants, especially tap-rooted vegetables, shrubs, or trees, due to root feeding.
- 4Irrigation lines that suddenly lose pressure or show chewed tubing.
- 5Large areas of sunken or uneven turf caused by tunnels collapsing.
- 6Fresh mounds appearing overnight or after rain.
- 7In lawns, a network of raised ridges (less common than mounds, but possible in shallow tunnels).
Why it’s worth acting soon
- Tunnel systems expand rapidly, leading to more mounds and lawn damage.
- Root damage can kill mature trees and shrubs, creating liability and replacement costs.
- Irrigation line repairs become frequent and expensive.
- Erosion can occur on slopes where tunnels destabilize soil.
- Secondary pest issues (e.g., snakes or rodents using abandoned tunnels).
Treatment options and typical costs
Professional Trapping (Most Effective)
$150-$500 per treatment (depending on acreage and infestation level)
pest control pros place two-pronged traps in active tunnels. Traps are checked and reset until the gopher is caught. Service includes locating active runs and sealing mounds.
- Time
- 1-2 weeks for initial control; follow-up visits may be needed
- Best for
- Property managers with moderate to large infestations who want results that vary by property and provider without environmental risks.
Baiting (Rodenticide Baits)
$200-$600 per treatment
Poison baits (usually strychnine or zinc phosphide) are placed in tunnels. Must be applied by a licensed professional in many states. Risk to non-target wildlife and pets if misused.
- Time
- 2-4 weeks; bait may need replenishment
- Best for
- Large areas where trapping is impractical, but only if non-target risks are managed.
Exclusion (Physical Barriers)
$0.50-$2.00 per square foot for materials + labor
Install 1/2-inch hardware cloth or gopher wire beneath lawns, gardens, and around tree roots. Requires excavation and is labor-intensive.
- Time
- Permanent if installed correctly
- Best for
- New construction or renovations; prevention in high-value areas like golf greens or flower beds.
Burrow Fumigation (Gas Bombs)
$300-$700 per treatment
Aluminum phosphide or gas cartridges are inserted into tunnels to produce toxic gas. Effective only if tunnels are sealed properly. Requires professional license.
- Time
- 24-48 hours; one-time treatment
- Best for
- Large, isolated infestations where trapping is impractical, but weather-dependent.

Gophers eat roots from below. Plants that wilt and lift out easily are a classic sign.Understanding Gopher Behavior for Better Control.
Gophers push soil to the surface in fan-shaped mounds, each with a plugged hole off to one side. They are most active in early morning and late afternoon, but can dig at any time. Understanding that each system holds one gopher is key: you don't have a colony, you have a series of individual territories. This means trapping or baiting must be done in each active system separately. Pocket gophers are solitary and territorial. Each adult lives alone in its own tunnel system, except during breeding season. A typical system includes a central nest chamber, food storage chambers, and a network of foraging tunnels. The main tunnels are usually 6-12 inches deep, but feeding tunnels may be shallower.
The Role of Soil and Season in Gopher Activity.
In winter, they remain active but may tunnel less in frozen soil. For property managers, this means spring and fall are the best times for treatment—traps are more likely to be found in active tunnels. It also means that an absence of mounds in summer does not mean the gophers are gone; they are simply deeper. A single gopher can survive weeks without surfacing, relying on stored food. Gopher digging activity is heavily influenced by soil moisture. In spring, melting snow and rain soften the ground, making tunneling easier. In fall, similar conditions occur as summer heat fades. During dry summer months, gophers may dig deeper to find moisture, reducing mound production.
Gopher mounds are fan-shaped, with a plugged hole off to one side.Legal and Environmental Considerations for Gopher Control.
For example, California requires a qualified applicator license for using strychnine. Some states have banned certain baits due to non-target risks. Fumigants like aluminum phosphide are restricted-use pesticides. Trapping, however, is generally unregulated and considered the most environmentally friendly method. For property managers concerned about pets, children, or wildlife, trapping is the safest option. Always check local regulations before applying any control method. In many states, the use of poison baits for gopher control is regulated.
What affects the price
- Size of property (acres or square footage of infested area).
- Severity of infestation (number of mounds and active tunnels).
- Accessibility (slopes, dense vegetation, or underground utilities).
- Treatment method chosen (trapping vs. baiting vs. exclusion).
- Number of follow-up visits included in the service contract.
- Regional labor rates (higher in coastal urban areas).

What’s the biggest challenge you face with gopher control?
When to call for help
A professional inspection is often free and can identify the extent of the problem quickly. If you see more than five fresh mounds per week, or if the infestation spans more than an acre, it’s time to call a professional. Also call if you have valuable landscaping, irrigation systems at risk, or if you’ve tried DIY methods without success.
What you can do yourself
For property managers, the cost of repeated DIY failures often exceeds the cost of a single professional treatment. However, for a single tunnel system in a low-risk area, a determined homeowner with a good trap can succeed. DIY gopher control usually involves flooding tunnels, using ultrasonic devices, or dropping poison baits. Flooding rarely works because the water drains away or the gopher simply blocks the tunnel. Ultrasonic devices have no scientific support and are ineffective. Baits can be effective but are dangerous to handle and require precise placement. Professional trapping, on the other hand, has a success rate of 90% or higher when done correctly.
Where you live matters
Gopher species and activity vary across the US. In the Pacific Northwest, the Mazama pocket gopher is a species of concern, meaning control must be done carefully to avoid harming protected populations. In California, the Botta’s pocket gopher is the most common, and heavy rains can cause tunnels to collapse, leading to sudden surges in mound activity. In the Great Plains, the plains pocket gopher thrives in agricultural areas, where it can damage row crops and irrigation pivots. In the Southeast, the southeastern pocket gopher is less common but still problematic in sandy soils. Regardless of region, the control principles remain the same: identify active tunnels, use traps or baits correctly, and prevent re-infestation with barriers.
Gopher tips from the experts
Fresh mounds tell the story
Around your home, fresh, dark soil means a gopher is active now. Look at the mound shape, the plugged hole and any wilting plants before deciding what you have.
Gopher, mole or ground squirrel?
Gopher mounds are crescent or horseshoe shaped, with a plugged hole off to one side. Mole mounds are rounder, often with raised ridges nearby. Ground squirrel holes stay open, with no mound.
UC IPM: pocket gophersWhat they damage
Gophers chew roots, irrigation lines and sometimes buried cables. Fresh, moist soil means they’re active now. Keep watching after treatment, since a quiet yard doesn’t always mean they’re gone.

How we check our sourcesSimple ways to keep gophers away
- Install 1/2-inch hardware cloth vertically along garden beds and tree roots to a depth of 18-24 inches.
- Reduce the planting of tap-rooted vegetables and bulbs; gophers prefer dandelions, alfalfa, and carrots.
- Maintain a mowed buffer zone around property edges to reduce cover for gophers.
- Use gopher baskets (wire cylinders) when planting new trees or shrubs.
- After trapping, backfill tunnels with gravel to discourage reoccupation.
- Monitor for mounds regularly, especially after rain or irrigation.
- Encourage natural predators like owls by installing nesting boxes (though this alone won't control an established infestation).
Mark fresh mounds on a sketch. New ones show where the gopher is working now.Did you know?
Gophers have fur-lined external cheek pouches used to carry food—they can stuff up to a handful of roots or grass in each pouch.
Their lips close behind their teeth so they can dig with their incisors without getting dirt in their mouth.
A single gopher can move roughly a ton of soil per year to the surface, aerating the soil but also creating mounds.
Questions people ask
How do I tell if a gopher mound is active?
If it is, the tunnel is active. Also, feel for a soft plug in the mound's side hole—fresh plugs are loose and crumbly. Flatten the mound and check if it is rebuilt within 24-48 hours.
Can gophers cause structural damage?
They rarely damage building foundations, but their tunnels can undermine sidewalks, driveways, and retaining walls if the soil erodes. They also damage irrigation lines and electrical cables buried in lawns.
How many gophers are typically on a property?
Each tunnel system usually has one gopher. On a 1-acre property with 10 active mounds, you likely have 5-10 separate gophers, as one gopher can create multiple mounds per day.
Are gophers active in winter?
They remain in their tunnels and feed on stored food. Mounds may be less visible until spring thaw. Yes, but activity decreases in frozen soil.
What is the best bait for gophers?
However, trapping is safer and equally effective. Always follow label directions and local regulations. Strychnine-treated grain baits are common but dangerous to non-target species. Zinc phosphide baits are also used.
How long does professional gopher control take?
Baiting may require 2-4 weeks. Exclusion installation takes 1-3 days depending on the area. Initial trapping typically takes 1-2 weeks to catch all gophers in an area.
Will gophers come back after removal?
Yes, if your property borders open fields or natural areas, new gophers may move in. Ongoing monitoring and exclusion barriers are the best long-term prevention.
Is it safe to use poison baits around pets?
Professional application reduces risk but does not eliminate it. Trapping is safer for homes with pets. Poison baits are toxic to dogs and cats if ingested. They should only be used in underground tunnels that are properly sealed.
How much does it cost to trap gophers?
Ask how many return visits the price includes, since traps must be checked and reset. It's a published estimate, not a local quote. In Property Managers, ask for a written quote that spells out visits and the warranty. Trapping is the usual choice for homeowners who want to avoid poison baits near pets, children or vegetable gardens.
How much does gopher removal cost?
Trapping alone is listed at $200 to $600. Because gophers recolonize from neighboring land, ask whether a quote covers follow-up visits or whether an annual contract would suit your property better. In Property Managers, ask for a written quote that spells out visits and the warranty.
