What Do Ground Squirrel Droppings Look Like? Ground squirrel feces are solid, brown to black in color, and more than one-half inch in length. Their shape is tubular and rounded at the ends. Since ground squirrels burrow rather than live in trees, their feces also don't have woody fibers like the waste left by tree squirrels. Ground squirrel droppings matching this description are a good indicator of an infestation. Risk of Diseases Ground squirrels and their waste are hazardous to human health and should not be approached or handled by people. Dead or alive, these pests can harbor fleas that carry the deadly bubonic plague. They are also associated with the spread of Rocky Mountain spotted fever, rat bite fever, and tularemia. If residents come in contact with ground squirrel droppings or saliva and begin to feel ill, they should seek immediate medical attention. Dealing with Ground Squirrels & Their Droppings The only way to avoid finding ground squirrel droppings in the yard is to prevent the pests from entering. Ground squirrels are naturally attracted to nut and fruit trees, so avoid these in landscaping plans to make residential spaces seem less inviting. Gardeners can also install fences that drop at least one foot below the surface of their garden to discourage burrowing, though this method is a cumbersome and costly process. Homeowners who see ground squirrel droppings or others signs of the pests should call Critter Control for safe and professional removal.
