When you hear the word mouse, you would usually think of that small creature you saw running stealthily around your kitchen or that tiny rodent you caught living under the comforts of your attic. But there are a hundred mouse species in the animal world that are further divided into subfamilies.
What is the difference between the deer mouse and the house mouse? As to appearance, a house mouse is usually less than five inches long with gray, light brown, tan, white, or black fur, but a deer mouse can grow to be seven inches long with gray or tawny brown fur on top and a white underbelly and feet. House mice have small, beady, black eyes, rounded ears, and prominent tail hairs, whereas deer mice have bigger eyes and ears but no tail hairs.
In this article, we’ll cover these two rodent species identifying characteristics, and the efficient ways of trapping and getting rid of them.

However, if this set-up opens them to exposure to humans and potential predators, this familiarity with other mice may change, and they may relocate to other places.
Do Deer Mice Carry Disease?
Deer mice are known to be vectors of hantavirus that can cause a disease called Hantavirus Pulmonary Syndrome. It is transmitted when a person comes in contact with an infected deer mouse, including their urine and droppings.
This can also be passed to humans when the latter inhale dust particles from contaminated urine and wastes. Common symptoms of this illness include fever, muscle pains, fatigue, headache, dizziness, nausea, abdominal pain, chills, and vomiting.
