Prairie dogs do carry fleas, but almost all small mammals do – rabbits, squirrels, mice, foxes, coyotes, raccoons, etc. The fleas, however, do not simply make a great leap from animal to human. Fleas are carried into homes – and onto people – usually by cats and dogs. If a dog is allowed to stalk rabbits, prairie dogs or other wildlife, then it might pick up fleas. Cats, when allowed to roam free, can pick up fleas from mice, voles and other animals. When pets come back into the house there is a chance that they’ll be carrying fleas that can bite humans.

People who live near prairie dog colonies also need to understand that fleas do not automatically die when prairie dogs are killed. The fleas just move on to other animals.

The threat of plague in the United States is miniscule. Three people contracted plague in Colorado last year. On average nationwide, only seven people contract plague annually, reports the U.S. Centers for Disease Control and Prevention. If a human contracts the disease, it can be controlled effectively with antibiotics.

Many people have many reasons to dislike prairie dogs. But remember, it is fleas that carry disease, not prairie dogs. Do not allow your pets to roam freely to harass wildlife – and consult your veterinarian about the best ways to keep fleas off your pet and out of your house.
