In terms of behavior, Bushy-tailed Woodrats are most active during the night and are known for their hoarding behavior. They collect a variety of objects, including plants, bones, and shiny items, which they store in their nests. They are herbivorous and feed on a variety of vegetation, including leaves, twigs, and fruits.
Characteristically, Bushy-tailed Woodrats have a medium-sized body, measuring about 14 to 17 inches in length, including the tail. They have bushy tails that are covered in long, soft fur, giving them their name. Their fur color is typically gray or brown, and they have large eyes and ears. Bushy-tailed Woodrats have a lifespan of around 2 to 8 years.
6. Canyon Mouse
The Canyon Mouse is a small rodent that can be found in rocky canyons and cliffs in Wyoming. They are adapted to living in arid environments and are commonly associated with dry, rocky habitats.
In terms of behavior, Canyon Mice are primarily active during the night, although they can occasionally be seen during the day. They are omnivorous, feeding on seeds, fruits, insects, and small vertebrates. They are excellent climbers and can navigate steep, rocky terrains with ease.

14. Diseases Carried by Mice and Rats
Mice and rats, including the various species found in Wyoming, can pose a health risk to humans due to the diseases they can carry. Some of the common diseases transmitted by these rodents include:
-
Hantavirus: Hantavirus is a potentially life-threatening disease that can be contracted by inhaling contaminated rodent droppings, urine, or saliva. Symptoms include fever, muscle aches, and respiratory distress.
-
Salmonellosis: Salmonellosis is a bacterial infection that can be transmitted through the consumption of food or water contaminated by rodent droppings. Symptoms include diarrhea, fever, and abdominal cramps.
-
Leptospirosis: Leptospirosis is a bacterial infection that can be acquired through contact with water or soil contaminated by rodent urine. Symptoms include fever, headache, muscle pain, and jaundice.
-
Rat-bite fever: Rat-bite fever is an infectious disease that can be transmitted through a bite or scratch from an infected rodent. Symptoms include fever, rash, and joint pain.
To minimize the risk of these diseases, it is important to practice proper rodent control measures, such as eliminating food sources, sealing entry points, and maintaining cleanliness in living areas. If a rodent infestation is suspected, it is recommended to seek professional pest control services for safe and effective removal. Additionally, practicing good hygiene, such as regular handwashing, can also help reduce the risk of disease transmission.
