The short version
Pocket gophers are solitary, territorial rodents that create extensive tunnel systems and multiple mounds daily. Professional trapping programs in Alaska typically cost $150–$700, with spring and fall being peak activity seasons.
- Gophers are active year-round in Alaska but peak digging occurs in spring and fall when soil moisture is highest.
- A single gopher can create several mounds per day and damage root systems, irrigation lines, and lawns.
- Professional trapping is the most effective method; costs range from $150 to $700 depending on property size and infestation severity.
- DIY methods like flooding or fumigation are rarely effective in Alaska's soil conditions.
For Alaska homeowners, property managers, and landowners dealing with gopher damage on residential lots, farms, or commercial properties. Whether you have a few mounds or a full infestation, you'll find practical, cost-effective solutions tailored to Alaska's unique conditions.
What to look for
However, a single gopher can create multiple mounds per day—up to 200 per year—displacing soil and damaging plant roots as they feed. In Alaska, the northern pocket gopher (Thomomys talpoides) is the primary species, found in areas with deep, loose soil such as river valleys, agricultural areas, and residential developments built on former farmland. Pocket gophers (genus Thomomys) are fossorial rodents that spend most of their lives underground. They are solitary and territorial, meaning each tunnel system typically houses only one gopher.
- 1Fresh mounds of loose, fan-shaped dirt (typically 6–12 inches wide) appearing overnight.
- 2Plugged burrow openings (gophers seal entrances from inside).
- 3Wilting or dying plants, especially vegetables, flowers, or young trees with gnawed roots.
- 4Irrigation lines with chew marks or reduced water pressure due to gnawing.
- 5Soft, spongy areas in lawns from collapsed tunnels.
- 6Horseshoe-shaped mounds near the main burrow entrance.
- 7Visible runways or raised ridges in soil (less common than mounds).
Why it’s worth acting soon
- Extensive root damage can kill ornamental plants, shrubs, and trees, leading to costly replacements.
- Tunnel systems can undermine patios, walkways, and retaining walls, causing structural issues.
- Irrigation and drainage pipes may be chewed, resulting in leaks or system failure.
- Mounds create tripping hazards and can damage lawn mowers.
- The gopher population can grow if left unchecked, as new individuals move into vacated tunnels.
Treatment options and typical costs
Professional Trapping
$150–$500
pest control pros set specialized traps (e.g., Macabee, Cinch) in active tunnels. Traps are checked and reset as needed until the gopher is removed. Service typically includes a warranty.

- 1–3 weeks depending on infestation severity
- Best for
- Most infestations; results that vary by property and provider with experienced pros.
Burrow Fumigation
$200–$400
Aluminum phosphide tablets are placed in active tunnels, releasing toxic gas. Must be done by certified applicators due to safety risks.
- Time
- Single application; requires follow-up to confirm
- Best for
- Large properties with multiple gophers where trapping is impractical.
Flooding
$0–$50 (DIY water cost)
Hosing water into tunnels to drown gophers. Rarely effective because gophers seal off sections and have emergency escape routes.

Hardware cloth under raised beds keeps gophers away from the plants you care about.Biology and Behavior of Alaska's Pocket Gophers.
In Alaska's winter, they remain active under snow cover, tunneling through the subnivean zone. During dry summer periods, they dig deeper to access moist soil and roots. They are active year-round, but peak digging occurs in spring and fall when soil moisture is optimal. Gophers are solitary and territorial; each adult occupies its own tunnel system, which can span 200–2,000 square feet. Their lips close behind their incisors, allowing them to dig with their teeth without swallowing dirt. These rodents are built for digging: they have large front claws, powerful shoulders, and fur-lined cheek pouches used to transport food. The northern pocket gopher (Thomomys talpoides) is the primary species affecting Alaska properties.
Regional Differences in Gopher Activity Across Alaska.
Property owners in Southcentral Alaska should be most vigilant, especially those on former farmland or near hayfields. In the Arctic and western regions, gophers are absent due to cold temperatures and shallow soils. Interior Alaska (Fairbanks area) has gophers in river valleys and agricultural zones, but permafrost limits their range. In Southeast Alaska, gophers are less common due to heavy rainfall and rocky soils. The highest densities occur in the Matanuska-Susitna Valley, Kenai Peninsula, and Anchorage area, where deep glacial soils and agriculture provide ideal habitat. Gopher populations are not uniform across Alaska.
Gopher mounds are fan-shaped, with a plugged hole off to one side.Cost Considerations for Alaskan Homeowners.
While DIY supplies are cheap (traps cost $10–$20), success rates are low, and repeated failures can exceed professional costs. Fumigation is more expensive due to licensing and safety requirements, often $200–$400 per treatment. Remote areas like Homer or the Kenai Peninsula may have travel fees of $50–$150 added. Larger properties (2–5 acres) may cost $300–$700. In the Anchorage and Mat-Su areas, a typical trapping program for a standard residential lot (0.25–1 acre) runs $150–$350. Gopher control costs in Alaska vary by location and infestation level.
What affects the price
- Property size and acreage (larger lots require more traps and visits).
- Number of active mounds (indicates population density).
- Accessibility of tunnels (sloped, rocky, or overgrown areas increase labor).
- Time of year (peak season may have higher demand).
- Geographic region within Alaska (remote areas may have travel fees).
- Need for additional services like damage repair or prevention.

What's the biggest challenge you face with gophers?
When to call for help
If you see more than 5–10 fresh mounds per week, if plants are dying, or if tunnels are near structures, it's time to call a professional. DIY methods rarely eliminate the problem, and improper trapping can be dangerous. A licensed technician can assess the infestation and implement a targeted removal plan.
What you can do yourself
DIY gopher control often fails because gophers are wary of foreign objects and can quickly seal off tunnels. Flooding, smoke bombs, and ultrasonic devices are rarely effective. Professional trapping, on the other hand, uses proven techniques like the Macabee trap, which is placed inside active tunnels and triggers a quick kill. While DIY may save money upfront, repeated failed attempts can cost more in time and plant damage. For most Alaska properties, professional service is the most cost-effective and reliable option.
Where you live matters
In this area, the local climate means gophers activity tends to follow the warmer months, so scheduling the visit before the busy stretch usually means a faster response and a cleaner quote. For city-specific help, local pest control directories or cooperative extension offices can provide referrals. Regardless of region, spring and fall are peak seasons for activity, and professional services are available statewide, though remote areas may have fewer providers. Southeast Alaska (Juneau, Ketchikan) has few gophers due to heavy rainfall and shallow soils. In Interior Alaska, Fairbanks-area properties along the Tanana River may see gophers, but populations are lower. On the Kenai Peninsula, gophers are common in Soldotna, Kenai, and Homer, especially near river corridors. Homeowners in Palmer, Wasilla, and the Anchorage Hillside often report recurring issues. In Southcentral Alaska, the Matanuska-Susitna Valley has some of the highest gopher densities, thanks to deep, fertile soils from glacial deposits. Alaska's gopher control needs differ from the Lower 48 due to climate and soil.
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 fencing (1/4-inch hardware cloth) buried at least 18 inches deep around gardens.
- Remove food sources by controlling weeds like dandelions and clover.
- Avoid overwatering; moist soil attracts gophers and eases digging.
- Use gravel or coarse sand around foundations and utility lines to discourage tunneling.
- Maintain a buffer zone of short grass or bare soil between lawns and wild areas.
- Encourage natural predators like owls and hawks by installing perches.
- Inspect regularly for new mounds and act quickly before tunnels expand.
Ask what the quote covers if another gopher moves in after the first is caught.Did you know?
Gophers have fur-lined external cheek pouches that they use to carry food—they can hold up to 2 tablespoons of plant material per pouch.
Their lips close behind their teeth, allowing them to dig with their incisors without swallowing dirt.
A single gopher can move up to a ton of soil per year, redistributing nutrients and aerating the ground.
Questions people ask
How do I know if I have gophers or moles?
Gophers create fan-shaped mounds with a visible plug on one side, while moles create volcano-shaped mounds and surface runways. Gophers are also larger (6–10 inches) and have visible incisors.
What is the best time of year to trap gophers in Alaska?
Spring (April–May) and fall (September–October) are best because gophers are most active and soil is soft. However, trapping can be done year-round as long as the ground isn't frozen.
Are gophers dangerous to pets or people?
Gophers are not aggressive and rarely surface. However, their tunnels can collapse underfoot, causing injury. Traps are dangerous to pets if not properly placed; professional installation is safer.
Can I use poison baits to control gophers?
Poison baits are not recommended because they can harm non-target wildlife and pets. Many are illegal in Alaska or require a professional applicator. Trapping is safer and more effective.
How long does professional gopher control take?
Most infestations are resolved within 1–3 weeks with trapping. Follow-up visits ensure all gophers are removed.
Will gophers come back after trapping?
If the tunnel system is not properly collapsed and backfilled, new gophers may move in. Professional services often include tunnel collapse and prevention tips to reduce re-infestation.
How much does gopher removal cost?
In Alaska, ask for a written quote that spells out visits and the warranty. 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. It's a published estimate, not a local quote.
