OVERVIEW
Introduction To Deer Mice
With its big ears and white belly, a deer mouse is a cute little critter, to be sure. But when they come indoors, they're a pest, not a pet. These mice (Peromyscus maniculatus) can burrow into the corners of your home, chew through upholstery, and leave behind droppings that can carry hantavirus, a serious disease that affects human lungs. Knowing how to recognize deer mice and what to do if they've moved in is key to keeping your home clean and your health protected.

What Do Deer Mice Look Like?
Deer mice are recognized by their big black eyes and prominent ears. Small, furry, and objectively cute, they get their name from their deer-like two-tone coloring and somewhat oversized ears. Their coats are brown on top, and they have white bellies. Their long tails are about as long as their bodies.
BEHAVIORS
What Are Some Deer Mice Behaviors?
Nimble, quick, and most active at night, deer mice are as agile as their deer namesake. For shelter outside, they build cozy cup-shaped nests out of grass, leaves, twigs, fur, feathers, and other fibrous materials. They are skilled climbers that will scale branches, pipes, or walls in search of food. The deer mouse diet is flexible too, ranging from seeds and fruits to the occasional insect or other invertebrate. They're natural hoarders, stashing away seeds and nuts for leaner times. So you might notice a nest if you see a cluster of fuzzy materials or bits of food.
Do deer mice go inside homes?
Deer mice usually nest in tree hollows, under rocks and logs, or even in abandoned bird and squirrel nests. But when the weather turns cold, especially in rural and suburban areas near parks or forests, they will seek out the warmth and shelter of a house. They can slip in through the tiniest cracks and openings, then set up shop in attics, basements, wall voids, or storage areas. Inside, they make cozy nests out of whatever they can find, from fibers to hair, upholstery stuffing, and even clothing. Once they're in your home, they continue to cause problems. Deer mice will chew through all kinds of household materials while gathering nesting supplies, which means furniture, mattresses, and other belongings can take a hit. Signs of their presence include nests tucked into hidden corners, holes in soft furnishings, and telltale droppings. Measuring about a quarter-inch long with pointed ends, their droppings are easy to recognize and are often the first clear indicator that deer mice have moved in.
HARMFUL
Are Deer Mice Harmful To Humans?
Speaking of their droppings, that's where a deer mouse's risk to humans comes in. Deer mice are known to carry and transmit hantavirus, a serious and potentially fatal disease that affects human lungs. It lingers in their droppings, and even a small exposure can put your health at risk. You can become infected simply by inhaling aerosolized hantavirus from dried rodent droppings, urine, or saliva, or by touching contaminated surfaces and then your face. That's why it's extra important to keep deer mice out of your home — and to call for professional help if you think you have mice in your home. Remember, Hawx has your back on all pest control, including the handling of your deer mice infestation.
HANTAVIRUS
Do Deer Mice Always Carry Hantavirus?
No, not all deer mice carry hantavirus. Estimates vary, but studies suggest that, on average, only around 10–15% of deer mice may be infected with and carry the virus. Still, deer mice are the primary carriers of hantavirus in North America, and you never know if the mouse in your house has the disease. Don't risk it — get rid of it.
How long does hantavirus live in droppings?
Hantavirus can survive in rodent droppings for several weeks to months, depending on the temperature, humidity, and sunlight of your home. The virus is more stable in cooler temperatures and can survive for up to 3 months in frozen droppings. High humidity levels also favor the survival of the virus. Meanwhile, exposure to direct sunlight can kill the virus within a few hours. Some scientists suggest that the virus can survive an average of four weeks in the right conditions. But it is important to note that these are just estimates, and the actual survival time of the virus in deer mouse droppings can vary widely. It's impossible to tell which deer mice carry the virus and which don't, so it's crucial to take all precautions to avoid contact with these rodents and their droppings, urine, and nests. To reduce the risk of infection, always wear gloves and a respirator when cleaning up mouse droppings, and be sure to use bleach or another disinfectant to thoroughly sanitize the area. Droppings should be carefully sealed in plastic bags before disposal, and you should wash your hands thoroughly afterward. Taking these steps greatly lowers the chances of exposure to harmful pathogens.
Are Deer Mice Hard To Get Rid Of?
Deer mice aren't hard to eliminate with a professional pest control team like Hawx. For rodent infestations, it's best to contact a professional pest control service.
The process of getting rid of deer mice in your home involves a combination of sealing entry points, sanitation, and trapping. Hawx will start by making your home less inviting and harder to get into. We'll locate and seal up any cracks, gaps, or holes with sturdy materials like caulk or copper mesh so they can't sneak in. As a homeowner, you can do your part by storing all food (pet food included) in airtight containers and being diligent about cleaning up crumbs, spills, and trash. Clean up cluttered corners. Outside, keep your yard tidy by mowing the lawn, trimming back overgrowth, and clearing away any woodpiles that can double as mouse hideouts.
Each follow-up visit from Hawx will include bait-level checks, perimeter assessments, and digital service reports with photos and recommendations, so you always know your home's rodent defense is working.

I've been with Hawx for a few years. They have great customer service. I didn't like that the price went up and got charged without my being notified but I discussed that with them once I realized my auto charge was increased. The current technician I've been getting is Jose. He's pretty responsive and serviced specific areas I needed/requested
