Black-Tailed Prairie Dog Control


Prairie Dog Control

Prairie Dogs can be found in the plains states of the U.S. from the Canadian to the Mexican borders. There are over 4 species (Genus - Cynomys) in North America: Black-tailed, White-tailed, Gunnison’s, and Utah. Of these, the Black-tailed Prairie Dog is the most prevalent, creating management concerns for livestock producers, farmers, and landowners. Read more on how you can have effective prairie dog control.


Prairie Dog Control

  • One black-tailed prairie dog (BTPD) consumes up to 2 lbs. of vegetation every week.
  • An active prairie dog colony can cut grazing capacity by over 50%.
  • 250 prairie dogs can consume as much forage as one cow/calf unit (CCU).
  • Pastures with 20% prairie dog occupancy reduced the estimated value of livestock
    weight gain
    by over $14 per steer. In pastures with 60% BTPD occupancy, value per steer was reduced by $37.1
  • Prairie dog infestations can reduce land value over 35%, and rental income by
    up to 50%.
  • Land that has been devastated by a colony can take up to 20 years to recover to full
    grazing capacity.
  • Infested rangeland can require ranches to allocate up to 40 acres per steer, where as rangeland that is free of prairie dogs can often carry a steer on only 10 acres.

Steps to a Successful Black-tailed Prairie Dog Management Program

Site Assessment

Prairie Dog Control

  • Before applying this product, identify active prairie dog burrows by visual observation. When treating, think like a "hunter" – find the active burrows by verifying tracks, mound repair, or fresh droppings after a light rain or snowfall.
  • The openings of active burrows will generally be free of leaves, seeds, other debris or spider webs, and will show freshly turned earth, and/or may have prairie dog feces nearby.
  • To ensure a thorough site assessment, use the line-transect survey method.

Line-Transect Survey Method

Prairie Dog Control

  • Divide treated area into line transects to ensure a thorough inspection, and complete treatment coverage.
  • Transect center lines must be not more than 200 feet (about 60 meters) apart, and should be considerably less if searches are conducted in more densely-vegetated sites.
  • Use flags, stakes, a GPS or marker foam to designate treated areas.
  • Transect lines may be traveled on foot or by vehicle at a rate not to exceed 4 mph.

Habitat or Timing Restrictions - Due to Endangered Species

* Species examples may be Endangered, Threatened, or Listed.

Prairie Dog Control

  • For best results, apply in the absence of green vegetation or immediately prior to bad weather (rain or snow). This will increase the chances that prairie dogs remain in the burrow with the bait, and further promote feeding.

Application Rate / Directions for Use

  • ¼ cup (volume) per active burrow = 2 ounces = 53 grams of bait.
  • In order to use this product for the control of Black-Tailed Prairie Dogs, you must be a certified, state-licensed pesticide applicator, or under their supervision.
  • Application may be made by hand.

Prairie Dog Control

  • Application may be made with a mechanical bait application machine that is designed, constructed and operated in a manner that ensures that bait is properly placed at least 6 inches down the prairie dog burrows.
  • Apply bait only to active burrows. Bait must be applied a minimum of six inches down prairie dog burrows.
  • Make sure no bait is left on the soil surface at the time of application. Applicator must retrieve and dispose of any bait that is spilled above ground or placed less than 6 inches down the burrow entrance.
  • If adjacent properties are infested, discuss treatment practices with neighboring landowners. Consider treating properties at the same time to create buffer zones that reduce chances of re-infestation.

Grazing Restriction

Prairie Dog Control

  • Do not allow livestock to graze in treated areas for 14 days after treatment and until  no bait is found above ground.
  • Do not allow children, pets or domestic animals to be in the area where product is being applied.

Post Application Follow-up – Carcass Search

Prairie Dog Control Prairie Dog Control

  • Prairie dogs that have eaten this bait will begin to die off 4 to 5 days after they eat a lethal amount.
  • Applicator is responsible for conducting the search. Landowner or designee under the applicator’s direct control may perform the search.
  • The applicator must return to the site within 4 days after bait application, and at 1-2 day intervals, for at least two weeks - but longer if carcasses are still being found at that time.
  • Carcass searches must be performed repeating the line-transect survey method used prior to bait application. Downloadable, printer-friendly PDF of FWS-approved line transect method guidelines.
  • Best time of the day to conduct it: late afternoon, near sundown to reduce the potential of nocturnal animals finding carcasses and dying animals.
    • Although the label requires only one search every two days, USFWS recommends twice-daily searches.
    • A longer search duration (e.g., until no carcasses or bait has been found for five (5) consecutive days) would help to minimize risks of secondary poisoning to predators and scavengers, given the variability in scavenger removal.
  • Steps to follow if dead/dying non-target is found: Call the National Pesticide Info. Center: 800-858-7378
    • If a Federally Listed species, also call:
      • In CO, KS, MT, ND, SD, NE, or WY - 303-236-7540, or
      • In NM, OK or TX – 505-248-7889
    • The Black-footed Ferret Coordinator must also be contacted if ferrets are found before, during, or after application, or during carcass searches at 970-897-2730 x224. If live black footed ferrets are found outside reintroduction sites, before, during or after Rozol Prairie Dog Bait application, the Black-footed Ferret Coordinator must be contacted immediately and sufficient time must be allowed for the capture and relocation of the black-footed ferret(s) before Rozol Prairie Dog Bait application.

Carcass Disposal

  • Bury carcasses on site in holes dug at least 18 inches deep to avoid non-target animal scavenging.
  • Burial includes covering and packing the hole or burrow with soil.
  • If burial is not practical (due to frozen ground, etc.) and other disposal methods are allowed by state and local authorities, collected carcasses may be disposed of by other methods to insure that the carcasses are inaccessible to scavengers.


  • If prairie dog activity persists several weeks or months after the bait was applied, a second application may be made, by treating burrows in the same manner, time period and procedure as the first application.
  • Do not use any other rodenticides containing anticoagulants (e.g. diphacinone) in prairie dog towns during the treatment period on this label. A maximum of two applications TOTAL of Rozol Prairie Dog Bait  can be made per labeled use season.
  • It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Follow all applicable directions, restrictions and precautions on the Federal EPA-registered label.
