Managing Prairie Dogs on Agricultural Lands

Managing Prairie Dogs on Agricultural Lands Cory Farnsworth and Nicki Frey, Ph.D.

Introduction Utah is home to three of the five species of prairie dogs in North America, the Utah prairie dog (Cynomys parvidens), Gunnison’s prairie dog (Cynomys gunnisoni), and white-tailed prairie dog (Cynomys leucurus) (Division of Wildlife Resource, 2026). Prairie dogs belong to the Sciuridae (squirrel) family and occur in the grasslands of the United States and Mexico (Witmer et al., 2023; Figure 1). The three species in Utah can be hard to distinguish, so it is often best to refer to their distribution for quick identification.

Animals within each species are often 12–16 inches long and weigh 14–59 ounces (1–4.5 pounds; Bowers et al., 2004).

Prairie dogs are considered a “keystone species” because their burrows provide shelter for a suite of wildlife species; they are also a prey species for many mammals and birds.

However, because of their diet and ability to burrow, they compete with agricultural practices, including alfalfa production and livestock grazing. Therefore, they can be considered a conflict species around human development.

General Ecology Prairie dogs live in colonies, a community of family groups, within burrow systems. The density Figure 1. Distribution of Prairie Dog Species Native to and extent of the burrow system and colonies North America differ among the species. Prairie dogs forage on a Source: Whitmer et al., 2023 mixture of grasses and forbs throughout the day, distributed from open prairies to high mountain valleys; they may hibernate during extensive cold periods, and stay underground during hot days.

A prairie dog colony is formed by a group of coteries. Each coterie consists of a breeding male and female, several female offspring, and the young born that year. Prairie dogs reach maturity in their first winter and breed from January to 1

March, with northern locations breeding later. Up to six young are born, remaining in the burrow for 6 weeks before emerging, usually in May and June. By fall, the young are fully grown, and juvenile males may begin dispersing during this time. Usually, juvenile males have dispersed by the age of 2 to form their own coterie. Juvenile females will often stay at their natal burrow.

The presence of prairie dogs in an area can be determined by the presence of several burrows in proximity. Not all burrows will have an associated mound of soil (Figure 2). Burrow entrances are never buried, and the holes are approximately 4 inches wide. Additionally, the grass in the colony will be eaten, leaving a barren, patchy landscape compared to the surrounding habitat. Sometimes, when prairie dog density is low, it is difficult to determine whether the grass has been reduced. However, one can easily find prairie dog burrows. Usually, a prairie dog or two can be seen and heard defending their burrow upon your arrival.

The Utah prairie dog is found in Beaver, Garfield, Iron, Kane, Piute, Sevier, and Wayne counties in Utah’s Southwest; no other species of prairie dogs occur in these counties (Figure 3). Utah prairie dogs have cinnamon to clay-colored fur (Figure 3). They also have a dark eyebrow or black spot above each eye. Utah prairie dogs are listed as threatened and protected under the Endangered Species Act. Due to their protections, it is illegal for anyone to lethally remove or harm this species without first consulting with the Utah Division of Wildlife Resources. For more information on managing Utah prairie dogs on agricultural and private lands, see USU Extension’s “Managing Utah Prairie Dogs on Private Lands” (Frey, 2015). This article focuses on managing Gunnison and white-tailed prairie dogs rather than Utah prairie dogs.

Gunnison’s prairie dogs are found in southeastern Utah (Grand and San Juan counties east of the Colorado River), and parts of Colorado, Arizona, and New Mexico. They are yellowish-buff with black guard hairs; usually their head and cheeks are slightly darker than their body (Figure 4).

Due to their limited population distribution, the Western Association of Fish and Wildlife Agencies (WAFWA) determined a conservation plan to outline research needs and manage conflicts (WAFWA, 2007). Additionally, Utah created a Gunnison’s conservation plan (Lupis et al., 2007) that aligns with WAFWA. Hunting or shooting Gunnison’s prairie dogs is prohibited on public lands from April 1 to June 15, but they can be removed from private lands year-round (R657-19-10) without bag or possession limits (R657-19-5; Division of Wildlife Resources, 2026).

White-Tailed Prairie Dog White-tailed prairie dogs can be identified by their bright white tail tip (Figure 5).

White-tailed prairie dogs are distributed through Wyoming, Colorado, Utah, and Montana (Knowles, 2002). In Utah, white-tailed prairie dogs can be found in Rich, Summit, Daggett, Uintah, Duchesne, Carbon, Emery counties, and west of the Colorado River in Grand County (WAFWA, 2007).

Similar to Gunnison’s prairie dogs, white-tailed prairie dogs are a species of greatest conservation need in Utah due to their declining numbers. WAFWA and Utah have written conservation strategies for white-tailed prairie dogs (Lupis et al., 2007) in an effort to keep them off the endangered species list. In Utah, hunting or shooting white-tailed prairie dogs is prohibited on public lands from April 1 to June 15, but they can be removed from private lands year-round (R657-19-10) without bag or possession limits (R657-19-5; Division of Wildlife Resources, 2026). However, because they are an important prey species to the endangered black-footed ferret (Mustela nigripes), no hunting is allowed within the black-footed ferret recovery area that borders Colorado (Table 1, Figure 6).

Prairie Dogs and Human Conflicts Human Health The primary concern with prairie dogs is their ability to contract plague, a bacterial disease caused by the bacteria (Yersinia pestis) transmitted by a flea bite.

Other mammals, wild or domestic, can contract the plague by being bitten by an infected flea or eating an infected prairie dog. Humans can also contract plague by getting bitten by a flea.

While extremely lethal to prairie dogs, the plague can be treated in humans and pets with prompt and proper medical attention. Most prairie dogs live in Figure 6. Area Closed to White-Tailed Prairie Dog Hunting remote areas where the possibility of interacting with Due to Black-Footed Ferret Recovery Areas people or their pets is very low. However, in some areas, such as agricultural land where prairie dogs are located, interactions might occur. If you encounter a dead prairie dog, do not handle it or allow your pet near it. If your pet has encountered a prairie dog where plague is suspected, seek advice from a veterinarian.

Agriculture Prairie dogs can reduce crops, like wheat, alfalfa, vegetables, and orchards (Figure 7), and in some species, reduce forage availability. Burrows and their holes can damage farm equipment and endanger livestock use of the land (Elmore et al., 2006).

Prairie dogs prefer loose soil that is easy to dig, which helps them build and maintain a burrow system. Unfortunately, these soils are also desirable for croplands, such as irrigated grains and orchards.

Methods to Reduce Conflicts on Agricultural Lands Habitat Modification Prairie dogs prefer short, sparse vegetation throughout their colony. This helps them maintain their safety. Managing cattle through a rest-rotation schedule can help to increase the height of the surrounding vegetation. Black sediment cloth can also create a temporary visual barrier around crops, making the area less comfortable for prairie dogs. Similarly, planting a border of taller crops to protect short crops can discourage prairie dogs (Witmer et al., 2023).

Exclusion Creating fences to exclude prairie dogs can be effective (Franklin & Garrett, 1989; Witmer et al., 2008). However, the fencing must be installed belowground as well as above to discourage digging. Therefore, fencing can be an expensive management option. However, if protecting high-value or longlived perennial crops such as orchards or alfalfa, the reduction in damage may support the cost of fencing.

Shooting

Focused shooting of prairie dogs can be effectively reduce conflicts when populations are high; however, it is not a useful method in controlling population numbers over time. At lower populations, other methods of reducing conflict may be more efficient. However, take care to follow the regulations outlined for each species (Table 1). Generally, shooting is considered a temporary solution and is often used in conjunction with other management methods. Additionally, prairie dogs learn quickly to avoid people, which increases the difficulty of shooting over time (Witmer et al., 2023).

Generally, a .22 caliber rifle is suitable for shooting prairie dogs. The advantage of this method over toxicants and fumigants is that there are no nontarget risks. More recently, hunters may use CO2 or pre-charged pneumatic air rifles, which are generally quieter and thus may be more successful at not alarming the target.

Trapping Live trapping can be an effective tool for removing prairie dogs from problem areas, but it is not a useful tool for managing prairie dog populations. Lethal trapping, using body-gripping or piercing traps, is an effective tool for removing prairie dogs from problem areas and potentially decreasing their numbers. While it takes time to trap effectively, there is little nontarget hazard, and one can be confident that the problem animals are removed.

We recommend a 120 body grip trap, with two springs, which ensures a humane kill. The trap is 4.5 by 4.5 inches and works well on Gunnison’s prairie dogs. With some trigger adjustments (using a pan on the triggers for the animals to step on), they may also be successful on white-tailed prairie dogs. If pets are in the area, avoid the larger 120 body grip traps.

For white-tailed prairie dogs, which are smaller than Gunnison’s, a # 1 long spring trap (Figure 8) will catch the animal by the paw and restrain it until the animal can be killed humanely. These traps need to be checked daily, ideally each morning and evening to ensure the animal does not suffer. Traps need to be staked down as birds of prey and other predators will try to drag trapped animals away.

Tunnel traps are a striking killing trap, but due to the usually steep entrance of the hole, the traps don’t perform well in most scenarios. Cage traps and tunnel traps are both more expensive than other trap options. If cage traps are used, remember that it is illegal to relocate wildlife (Farnsworth & Frey, 2025).

Poison Baiting (Oral Toxicants) Poison baits, or toxicants, can be successful at removing prairie dogs.

Generally, grain such as oats or wheat is coated with a toxicant and considered “bait.” Prior to using this treated bait, one disperses non-coated grain to acclimate the prairie dogs to eating this food source. Once the prairie dogs are known to be consuming the grain, one begins to distribute the bait Figure 8. A #1 Long Spring Trap according to the label directions. Generally, oral toxicants are used outside of Useful for Catching White-Tailed the normal growing season, when fresh vegetation is less available, and Prairie Dogs animals are looking for seeds and grains. These poisons are usually not lawful to be used aboveground and must be placed in bait stations or belowground to avoid poisoning nontarget species.

Poison must be used according to the label.

Toxicants are regulated by the state of Utah and federal agencies to control the method and timing of application in order reduce nontarget hazards (including humans) and increase the toxicant’s effectiveness. Label restrictions and instructions should be strictly followed when using this method. To date, all toxicants that are labeled for use on prairie dogs—zinc phosphide and diphacinone—are restricted use pesticides and can only be used by a certified pesticide applicator.

Registrations change, so check regulations before use. Oral toxicants pose a nontarget hazard to other vertebrate species; additionally, predators can suffer when they eat prairie dogs killed by toxicants.

Thus, 2 or 3 days after applying toxicants, survey the area and remove any dead prairie dogs that are aboveground.

Fumigation Fumigation involves using gas cartridges or reactive tablets that produce toxic gases to fill a burrow system and kill prairie dogs.

Unfortunately, fumigants are nonspecific and will kill all animals living within the burrow system. Therefore, one should ensure other sensitive species, such as burrowing owls and black-footed ferrets, are not residing in the area prior to the use of fumigants.

There is one gas cartridge fumigant registered for nonrestricted use to control prairie dog populations. It contains 53% sodium nitrate, 28% charcoal (containing carbon), and 19% inert ingredients (Witmer et al., 2023). Aluminum phosphate and magnesium phosphate tablets are also successful fumigants.

These products are restricted use pesticides and can only be used by certified pesticide applicators (Witmer et al., 2023).

Encouraging Avian Predators (Owl Boxes and Hawk Perches) Encouraging avian predators of prairie dogs is an emerging practice; however, to date, this method has not been shown to reduce an area’s prairie dog numbers significantly. Installing raptor perches along agricultural fields can encourage species such as red-tailed hawks, ferruginous hawks, and eagles to hunt in the area. However, installing perches in 5

otherwise flat landscapes might increase the abundance of ravens, a species also known to cause damage to livestock operations.

Other Options Frightening devices are ineffective at removing prairie dogs from an area once they have already established their burrow system (Witmer et al., 2023).

Repellants are ineffective at removing prairie dogs from an area and are not registered for use with any species of prairie dog.

Summary While prairie dogs are an important species in the region, due to the damage they can cause in cropping and range systems, their populations may occasionally need to be controlled. After you have identified which prairie dog species you are in conflict with and the scope of the damage, you will want to decide how to manage them. If you are only dealing with a handful of animals or merely trying to maintain their population in your area, it is likely that hunting and trapping will be the most effective tool. In certain cases, you may be successful at excluding or deterring them with habitat modifications. If you are dealing with a large-scale problem, these management options may not be feasible or realistic, and you may be limited to toxicants and poisons. In most cases, an integrated approach will provide the most sustainability in managing prairie dogs. Always consider the safety of humans, pets, and wildlife when deciding the best management practices for managing prairie dogs in your area.
