The short version
Gopher control in North Dakota requires identifying active tunnels, trapping (the most effective method), and prevention.
- Pocket gophers are solitary and territorial; typically one gopher per tunnel system.
- Peak activity in North Dakota is spring and fall when soil moisture is ideal for digging.
- Trapping is the most effective and environmentally responsible control method.
- Professional services cost $150–$700 depending on property size and infestation severity.
- Prevention focuses on barriers, habitat modification, and early detection.
For North Dakota homeowners, ranchers, farmers, and property managers dealing with gopher activity on their land. Whether you have a small residential lawn or a large acreage, the principles of control are similar, but the scale and cost differ. If you're tired of mounds, damaged plants, and frustrated by DIY failures, you're in the right place.
What to look for
Pocket gophers (Geomys bursarius) are the primary species in North Dakota. They are solitary and territorial, meaning each tunnel system usually houses only one gopher. However, a single gopher can create several mounds per day and dig tunnels that cover hundreds of square feet. Their underground feeding damages root systems, kills plants, and can collapse soil, creating hazards for livestock and machinery.
- 1Fresh, fan-shaped mounds of loose soil (typically 6–12 inches wide) appearing daily.
- 2Plugged tunnels: gophers push soil to the surface and seal the entrance with a dirt plug.
- 3Wilting or dead plants, especially along a line (root damage from tunnel feeding).
- 4Visible raised ridges in lawns, indicating shallow tunnels.
- 5Irrigation issues: water pooling or uneven distribution due to tunnel damage.
- 6Damage to underground utility lines, irrigation pipes, or buried cables.
- 7Holes in the ground (usually plugged) that appear overnight.
Why it’s worth acting soon
- Extensive root damage can kill trees and shrubs, leading to costly replacement.
- Tunnel systems can undermine walkways, driveways, and building foundations.
- Irrigation lines and sprinkler systems may be chewed or displaced.
- Gophers attract predators like snakes, coyotes, and owls to your property.
- Rapid population growth: one gopher can multiply, but because they are territorial, waiting usually means existing gophers expand their systems—not that numbers skyrocket quickly.
Treatment options and typical costs
Trapping
$150–$500 for professional trapping programs (residential lots); larger properties $500–$700.
Two-pronged pincer traps (like Macabee or Victor traps) placed in active tunnels. This is the most effective and selective method. Traps must be set correctly and checked frequently.
- Time
- Results in 1–3 weeks; active until no new mounds appear.
- Best for
- Homeowners, small to medium properties, environmentally conscious clients.
Baiting (Rodenticides)
$200–$600 for professional baiting programs.
Toxic baits (typically strychnine or zinc phosphide) placed in tunnels. Requires careful handling to avoid non-target poisoning. Not recommended near pets or livestock.
- Time
- Bait consumption and death occur within a few days; multiple treatments may be needed.
- Best for
- Large acreages, agricultural fields, where trapping is impractical.
Fumigation (Gas bombs or carbon monoxide)
$300–$700 for professional fumigation.
Gas cartridges or CO machines inject toxic gas into tunnels. Effectiveness varies with soil type and moisture. Less common due to safety concerns.
- Time
- Immediate effect if gas reaches the gopher; but often only kills one gopher per treatment.
- Best for
- Isolated infestations, areas where trapping is difficult.
Exclusion (Underground fencing)
$0.50–$2 per linear foot for materials; labor extra.
Hardware cloth or gopher wire buried 2–3 feet deep around gardens or foundations. Prevents new gophers from entering but does not remove existing ones.
- Time
- Permanent if installed correctly.
- Best for
- Prevention in high-value areas like gardens, orchards, or along foundations.

Gophers eat roots from below. Plants that wilt and lift out easily are a classic sign.Understanding Gopher Behavior and Biology in North Dakota.
Pocket gophers are fossorial (burrowing) rodents that spend almost their entire lives underground. They are solitary and territorial, with each individual maintaining a tunnel system that can span 200–1,000 square feet. Their lips close behind their incisors, allowing them to dig with their teeth without swallowing dirt—a key adaptation. They have fur-lined external cheek pouches used to carry food, primarily roots, tubers, and vegetation. In North Dakota, gophers are active year-round but are most visible in spring and fall when they push up mounds of fresh soil. During winter, they tunnel under snow and create 'snow mounds' that are visible after melt. Understanding their solitary nature is crucial: each tunnel system typically holds one gopher, so multiple mounds often mean multiple gophers—or one very active gopher.
Trapping: The Gold Standard for Gopher Control.
Trapping remains the most effective and environmentally responsible method for gopher control. The key is to locate active tunnels, not just mounds. To find the main runway, probe with a metal rod near a fresh mound; you'll feel a soft spot about 6–12 inches from the mound's plug. Open the tunnel, set a two-pronged pincer trap (like a Macabee or Victor) according to the manufacturer's instructions, and cover the opening with a light-excluding material (e.g., a bucket or plywood). Check traps daily. In North Dakota, spring and fall are ideal for trapping because soil moisture makes tunnels easier to find and gophers are more active. Professional trappers can often clear a residential property in 1–3 weeks. Trapping is selective, so pets and wildlife are not at risk—unlike poisons.
Pocket gophers are stocky, with cheek pouches and long front claws. Each one lives alone.Regional Considerations for Gopher Control Across North Dakota.
North Dakota's varied geography—from the Red River Valley in the east to the Missouri Plateau and Badlands in the west—affects gopher populations and control strategies. In the east, where soils are deeper and more fertile (glacial till and lakebed sediments), gophers thrive in agricultural fields and lawns. Urban areas like Fargo, Grand Forks, and Bismarck see frequent residential infestations. In the west, where soils are more sandy and rocky, gophers are still common but tunnel systems may be shallower and harder to treat. Western ranchers often deal with gophers in pastures and rangeland, where trapping is impractical and baiting is more common. Climate also matters: wetter springs in the east mean earlier gopher activity, while western areas may see a later peak. Always choose a control method that matches your local conditions. Professional services in North Dakota are familiar with these variations and can tailor their approach.
How big a gopher problem really is.
In North Dakota, state wildlife agencies put a single pocket gopher at roughly a ton of soil moved per year, and mounds are the first thing most people notice. In North Dakota, tunnel systems typically run 6 to 12 inches below the surface, with deeper nesting and food-storage chambers. In North Dakota, because each gopher is solitary, a yard with several fresh mounds usually means several animals, each with its own network. In North Dakota, count the active mounds during your walk-through — that number, not a national average, is what should drive a treatment plan.
What affects the price
- Property size and acreage: larger lots require more traps, bait, or labor.
- Severity of infestation: number of active mounds and tunnels.
- Treatment method: trapping is often more labor-intensive than baiting.
- Accessibility: steep slopes, heavy brush, or remote areas increase time/cost.
- Regional cost of living: urban areas like Fargo may have higher service rates than rural counties.
- Season: spring and fall are peak times, so scheduling may affect availability.

What's your biggest challenge with gophers?
When to call for help
If you have multiple active mounds, damage to landscaping or irrigation, or if DIY trapping has failed after two weeks, it's time to call a professional. Gophers are solitary but persistent; a pro can quickly locate active tunnels and set traps correctly.
What you can do yourself
DIY trapping can work for a single gopher on a small lawn, but it requires patience, proper trap placement, and regular checking. Many homeowners struggle to locate active tunnels or use the wrong trap type. For larger properties or multiple gophers, professional service is usually more cost-effective and faster. Baiting and fumigation are best left to pros due to safety and legal restrictions.
Where you live matters
Professional gopher control services are available in all major cities, but availability and pricing may vary. Across the state, the peak season is spring (March–May) and fall (September–November). Ranchers often use baiting on large acreages. In the west (Williston, Dickinson, Badlands), soils are more variable; gophers are still problematic but control may require different tactics due to rocky soil. The Missouri River corridor provides good habitat. In the central region (Bismarck, Mandan, Minot), gophers are common in both urban and rural settings. Homeowners often battle gophers in lawns and gardens. Fargo, Grand Forks, and smaller towns like Wahpeton see high activity in spring and fall. In the Red River Valley (east), soils are deep, rich, and moist—ideal for gophers. North Dakota's gopher problem is statewide, but regional differences matter.
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 underground barriers (gopher wire) around gardens and foundations—bury 2–3 feet deep with an L-foot at the bottom.
- Reduce food sources: control weeds (especially dandelions and clover) that gophers eat.
- Keep lawns mowed and irrigated evenly; gophers prefer moist soil but avoid waterlogged areas.
- Use castor oil-based repellents (granules or sprays) as a deterrent, though effectiveness varies.
- Encourage natural predators: owls, hawks, and coyotes can help control populations.
- Inspect your property regularly for fresh mounds and address them immediately.
- Avoid overwatering; gophers are attracted to moist soil for easier digging.

Gophers have fur-lined external cheek pouches that they use to carry food back to their burrows.
They can close their lips behind their incisors, allowing them to dig with their teeth without swallowing dirt.
A single gopher can move roughly a ton of soil per year, aerating the ground but also causing damage.
Questions people ask
How do I know if I have gophers or moles?
Gophers create fan-shaped mounds with a plug on one side, while moles create conical mounds with no plug. Gophers also leave raised ridges in lawns (tunnels), and they eat roots, causing plants to wilt. Moles eat insects and leave volcano-shaped mounds.
What is the best time of year for gopher control in North Dakota?
Spring (March–May) and fall (September–November) are best because gophers are most active and tunnels are easier to locate. Soil moisture is higher, making digging easier for them and trapping more effective.
Can I use poison bait to kill gophers?
Yes, but it requires careful handling. Baits containing strychnine or zinc phosphide are common but are toxic to pets, livestock, and wildlife. Many states have restrictions. Professional application is recommended for safety and effectiveness.
How many gophers are in a tunnel system?
Typically one. Pocket gophers are solitary and territorial. Each tunnel system usually houses a single gopher, except during breeding season when a female may have young. Multiple mounds may indicate multiple gophers or one very active animal.
Will gophers go away on their own?
No. Gophers are territorial and will stay as long as food and habitat are available. They do not migrate or abandon their tunnels unless conditions become unfavorable (e.g., flooding). Without control, they will continue to expand their tunnel system.
How long does professional gopher control take?
Most residential trapping programs show results in 1–3 weeks. Baiting may work faster (a few days) but requires multiple visits. Larger properties may take longer.
Are there any natural predators that can help control gophers?
Yes. Owls, hawks, coyotes, foxes, and snakes prey on gophers. Encouraging these predators (e.g., installing owl boxes) can help reduce populations, but they rarely eliminate an infestation on their own.
Do ultrasonic repellents work for gophers?
No. There is no credible scientific evidence that ultrasonic devices repel gophers. They are a waste of money. The most effective methods are trapping and habitat modification.
