Getting rid of prairie dogs requires a combination of methods, and the right approach depends on the size of the colony, your local laws, and whether you want a lethal or nonlethal solution. Most homeowners in the western U.S. dealing with prairie dogs on their property can legally remove them, but the rules vary significantly by state, and some methods require permits or professional help.
Check Your State’s Laws First
Prairie dogs are regulated differently depending on where you live, and skipping this step can result in fines. In Colorado, landowners can lethally remove prairie dogs from their property at any time without a hunting license when the animals are causing damage to property, crops, or livestock. Anyone helping you is considered your agent and can also do so legally. However, capturing, transporting, and relocating prairie dogs without a Colorado Parks and Wildlife permit is illegal, and transferring them across county lines requires approval from the receiving county’s commissioners.
In Kansas, using fumigants requires a permit from the state Department of Wildlife and Parks, and only people certified to use restricted-use pesticides can legally apply certain fumigant products. Other states have their own rules. Before you do anything, contact your state wildlife agency to find out what’s allowed on private land and what requires a permit.
Make Your Yard Less Attractive
Prairie dogs prefer short grass and open sightlines. They need to see predators coming, so they avoid areas with tall, dense vegetation. One of the simplest long-term strategies is to let your grass grow taller and mow less frequently in the areas near burrow activity. Planting fast-growing shrubs, tall grasses, or even placing hay bales along the edge of an active colony creates a visual barrier that makes prairie dogs uncomfortable enough to stop expanding or even relocate on their own.
Visual barriers work because prairie dogs rely heavily on line-of-sight communication and predator detection. Options include vinyl barrier fencing, snow fencing, wood-slatted privacy fencing, or dense plantings of shrubs and trees. Installing raptor perching poles or nesting boxes near the colony can also help by attracting hawks and owls, which are natural predators. These habitat modifications won’t eliminate an established colony overnight, but they can prevent new colonization and pressure smaller groups to move.
Fumigation for Active Burrows
Fumigation is the most common professional method and the one most likely to eliminate an established colony. The process involves dispensing gas-producing tablets or cartridges into each active burrow, then sealing the entrance with crumpled newspaper or a piece of sod topped with packed soil. The two main types are aluminum phosphide tablets, which release a toxic gas, and gas cartridges containing sodium nitrate and charcoal, which produce carbon monoxide and carbon dioxide when ignited.
Before fumigating, you need to identify which burrows are actually active. The standard technique is to shovel dirt over every burrow entrance or place a dried cow chip on top, then return three to four days later. Only the holes that have been reopened need treatment, which saves time and money. Fumigants work best when the soil is moist, because dry, cracked soil lets gas escape through the ground before it reaches the animals.
A single round of fumigation rarely gets every animal. Professional services typically return four to ten days later to treat any reopened burrows. Some offer extended service plans with a second follow-up later in the season. You can check your own results by plugging treated burrows, flagging them, and counting how many reopen within 24 hours.
Fumigation kills everything inside the burrow, including burrowing owls, snakes, and other wildlife. If your area has endangered species concerns, particularly black-footed ferrets, your state may impose additional restrictions.
Poison Baits as a First Step
In states where they’re registered for prairie dog control, grain baits and pellets containing zinc phosphide or anticoagulant compounds are often used before fumigation rather than as a standalone solution. Baiting reduces the colony’s population so that follow-up fumigation is more effective and requires less product. Only products specifically labeled for prairie dog control are legal to use, and label directions must be followed exactly.
The major drawback of poison baits is that they can kill other birds and mammals that eat the treated grain. This secondary poisoning risk is one reason many wildlife agencies and pest control professionals recommend fumigation as the primary method for residential properties, where pets and non-target animals are more likely to encounter bait.
Why Poisoning Can Increase Plague Risk
Prairie dogs commonly carry fleas that transmit plague, the same bacterial disease that caused historic epidemics in humans. When prairie dogs die, especially in large numbers from poisoning, their fleas lose their host and actively seek new ones. Boulder County public health officials specifically warn that poisoning colonies releases fleas into the environment, creating additional risk to people and pets.
Domestic cats and dogs can contract plague by catching infected rodents or picking up infected fleas, then carry those fleas home. Cats can also become a direct source of human infection. If you have pets and an active prairie dog colony in your yard, keep cats indoors and dogs away from burrow areas. Symptoms of plague in humans include sudden fever, chills, severe headache, muscle aches, and painful swollen lymph nodes.
Live Trapping and Relocation
If you prefer a nonlethal approach, live trapping is possible but heavily regulated. In Colorado, you need a permit from Parks and Wildlife, a process that takes about 30 days. You must identify a suitable relocation site in advance and describe the relocation method in your application. Only cage or box traps are permitted, and traps placed on public land must be permanently labeled with the trapper’s name.
Relocation can only happen during specific windows of the year, and finding a willing receiving site is often the hardest part. The animals must be moved close to the time you plan to permanently alter the land, because prairie dogs will recolonize open ground quickly. For most homeowners, the permitting requirements and logistical challenges make relocation impractical compared to other options, but it remains an option if lethal methods aren’t something you’re comfortable with.
Hiring a Professional
For colonies larger than a handful of burrows, professional wildlife control is usually worth the cost. Professionals use aluminum phosphide (a restricted-use pesticide that requires certification) and carbon monoxide machines that pump cooled exhaust into burrow systems through a hose. These tools aren’t available to homeowners.
Pricing typically includes a trip charge based on distance plus a per-burrow treatment fee. As an example, one Colorado-based wildlife service charges trip fees ranging from $75 for nearby jobs to $375 or more for remote locations, with per-burrow costs on top. A full-service treatment includes initial fumigation, sealing of all burrows, and at least one follow-up visit to re-treat any reopened holes. For large colonies, expect to spend several hundred dollars or more depending on the number of active burrows.
Restoring Your Yard After Removal
Once the colony is gone, you still have a yard full of holes. Burrows can be leveled with a disk or flattened with equipment, but simply collapsing the surface mounds won’t prevent recolonization. Prairie dogs from neighboring colonies will move into intact tunnel systems. For a lasting fix, backfill burrow entrances with packed soil and reseed the area with taller grass species that discourage new prairie dogs from settling.
Monitor the area for several months after treatment. New mounds appearing within weeks likely mean survivors are still active underground or nearby animals have moved in. A second round of treatment is common and expected, especially for larger colonies. Combining physical burrow destruction with the vegetation changes described earlier gives you the best chance of keeping your yard prairie dog-free long term.
