Prairie Dogs in Your Colorado Yard or Neighborhood

Prairie Dogs on the Front Range

Black-tailed prairie dogs are the species most Front Range homeowners encounter. Their range covers the eastern plains, the urban fringe communities along I-25, and suburban areas extending into Jefferson, Arapahoe, Adams, Boulder, and Larimer counties. A colony can number in the dozens on a small lot or expand into a town covering several acres across adjacent properties and public land.

Prairie dogs are a keystone species — more than 100 other species depend on them directly or indirectly for food or habitat. Burrowing owls, ferruginous hawks, golden eagles, and black-footed ferrets all rely on prairie dog colonies. This ecological role is one reason Colorado regulates their management. It's also why simply eliminating a colony without understanding the legal requirements can create problems, including significant fines if endangered species are affected.

What You're Actually Dealing With

Prairie dog burrows are typically 3 to 14 feet deep and extend 10 to more than 100 feet horizontally. Volcano-shaped mound entrances are built to shed water and catch wind for ventilation. A single coterie — a family group — occupies roughly 1 to 2 acres. Burrow systems are extensive underground and their boundaries rarely align with property lines.

The practical problems homeowners report most often:

• Burrow holes creating tripping and ankle-twist hazards in yards and paths
• Undermining of fences, sheds, and other structures built on colonized soil
• Lawn and garden destruction from clipping and digging
• Expansion from a neighboring property or greenbelt onto private land
• HOA disputes over who is responsible for colony management
• Plague risk — prairie dog colonies in Colorado can carry and spread sylvatic plague

What Colorado Law Allows on Private Property

Under Colorado law, landowners or their agents may hunt, trap, or lethally remove prairie dogs on property they own or lease when the animals are causing damage to crops, real property, or personal property — without a hunting license. However, there are important limits:

• You must check for the presence of black-footed ferrets or burrowing owls before using rodenticides. These are federally protected species. Killing them — even unintentionally — can result in significant federal fines under the Endangered Species Act.
• Any use of rodenticides must follow label instructions exactly. Off-label use is illegal and can harm raptors and other predators that eat poisoned prairie dogs.
• Relocation requires a permit from CPW. You cannot simply trap and release prairie dogs without coordinating with the state.

For most residential situations, hiring a licensed pest control or wildlife management company is the practical path. They understand the legal requirements, have the equipment for burrow flooding or gas cartridge treatment, and can document the work if there are any legal questions later.

Relocation: What It Actually Involves

Prairie dog relocation sounds appealing but is expensive, logistically difficult, and has uncertain outcomes. CPW does not directly participate in or fund relocation — it issues permits and sets requirements. The actual trapping, transport, and release must be handled by a licensed contractor or coordinated private effort.

Finding a suitable release site is the biggest obstacle. The site must be appropriate habitat, large enough for the colony, on land where you have landowner permission, and in most cases within the same county. CPW must be notified in advance. Survival rates for relocated prairie dogs are not well documented, and releasing them into an existing colony increases stress on both resident and incoming animals.

Relocation is most realistic when a colony is small, a motivated party (such as a conservation organization or municipality) is involved, and suitable habitat is available nearby. For a backyard colony of 10–15 animals that has spread onto your lawn from a neighbor's property, the math rarely works in relocation's favor.

Practical Management Options

In order of typical cost and complexity:

• Exclusion barriers — burying wire mesh or hardware cloth 2–3 feet deep around gardens, structures, or specific areas prevents new burrow establishment but doesn't address an existing colony.
• Burrow flooding — using water or carbon dioxide gas to flush and collapse burrows. Effective short-term but labor-intensive, and burrows can be reoccupied from adjacent areas.
• Gas cartridges — aluminum phosphide cartridges placed in burrows and sealed. Effective lethal method. Requires reading and following label instructions carefully and checking for protected species first.
• Shooting — legal on private property. CPW notes intensive shooting during February and March, when colonies are most concentrated and reproduction hasn't yet occurred, is most effective at reducing population size.
• Rodenticides — zinc phosphide grain bait is the most common. Effective but requires caution regarding secondary poisoning of raptors and other wildlife. Read the label. Verify no black-footed ferrets or burrowing owls are present first.

CSU Extension recommends using multiple methods rather than relying on a single approach. Setting realistic expectations matters: you can reduce the colony size and prevent expansion into specific areas, but complete elimination from an area adjacent to open habitat is very difficult to maintain long-term.

HOA and Neighbor Situations

Many Front Range homeowners deal with prairie dogs that originate on HOA-managed greenbelts, open space, or a neighbor's property. This is where things get complicated.

If a colony has established on HOA common area, the HOA is generally responsible for management decisions. HOAs in Colorado are not required to eliminate prairie dog colonies, but they are typically responsible for maintaining common areas. If burrows are creating safety hazards or causing property damage, that's a reasonable basis for requesting action. Put the request in writing and document the specific damage.

If the colony originates on a neighbor's private property and is expanding onto yours, Colorado does not require your neighbor to control it. You can manage animals on your own property without your neighbor's participation, but you cannot take action on their land. If the situation is causing genuine property damage, consult an attorney about whether nuisance law applies in your specific circumstances.

Some Front Range municipalities — including several in Adams, Jefferson, and Larimer counties — have their own regulations regarding prairie dog management, which may be more or less restrictive than state law. Check with your city or county before taking action.

When to Contact CPW

Contact Colorado Parks and Wildlife when you need a relocation permit, have questions about protected species on or near your property, or are unsure whether the management methods you're considering are legal. CPW District Wildlife Managers can do site visits for unusual situations. Contact your regional CPW office for Front Range inquiries.
