Deer Mice in Georgia
Deer mice (Peromyscus maniculatus), small rodents that often invade homes, are well-known across the United States, including Georgia. These nocturnal creatures are part of the Rodentia order and are frequently mistaken for house mice. Although native to grasslands and wooded areas, deer mice will also make their way into homes, outbuildings, attics, and basements, particularly during colder months.
Understanding their habits, living environments, and potential dangers is crucial in preventing infestations. By recognizing the signs of rodent activity and understanding what attracts them, you can take proactive measures to protect your home or business. Effective prevention begins with knowledge, minimizing the risk of costly and disruptive infestations.
Deer mice are common in rural and suburban areas of Georgia. These adaptable mammals thrive in a variety of settings, ranging from neotropical environments to temperate forests and even near human habitation, such as garages or voids in walls.
What Do Deer Mice Look Like?
Deer mice are distinguishable by their bicolored fur, with a darker brown to grayish back and a white underbelly and feet. Their tails are also bicolored, matching their fur pattern, with a dark top and a lighter underside. These small rodents typically have slender, beady eyes and a pointed nose. Adults grow up to 3 to 4 inches long, not including their tail, which is usually equal in length to their body.
Signs of Deer Mice Infestation
Deer mice are elusive and mainly active at night (nocturnal), making infestations challenging to detect. However, there are clear signs that can indicate their presence:
Droppings: Small, dark feces found near food sources, along baseboards, or in attics and basements.
Gnaw marks: Chewing on wood, wires, insulation, or plastic.
Nests: Deer mice build nests out of soft materials like paper, grass, or fabric, typically in secluded areas such as wall voids, attics, or piles of debris.
Tracks: Their small tracks may be visible in dusty or dirty areas.
Noises: Scratching or scurrying sounds at night.
Habitat, Diet, Life Cycle & Behaviors
Where Do Deer Mice Live?
Deer mice are nocturnal and spend their days in cup-shaped nests made of stems, leaves, and fibrous materials. Nests are lined with feathers or shredded cloth and can be found in tree hollows, fence posts, abandoned squirrel and bird nests, and the underside of logs and rocks. Deer mice construct nests in low-activity areas such as basements, attics, garages, and crawl spaces in homes. Deer mice do not hibernate and may invade homes during winter, seeking shelter in storage boxes, wall voids, and upholstered furniture.
Diet
Deer mice have an omnivorous diet. They primarily feed on seeds, berries, and fruits but consume insects and other invertebrates. They are opportunistic eaters, meaning they’ll scavenge for food indoors when necessary and can even eat small pieces of carrion*. Storing food securely and sealing food containers can reduce the chances of attracting deer mice into your home.
*Carrion refers to the decaying flesh of dead animals, which deer mice may consume if other food sources are scarce.
Life Cycle
The life cycle of a deer mouse is relatively short. A female deer mouse can give birth to multiple litters each year, each containing three to six hairless, blind young. These juveniles grow quickly, developing fur within days and opening their eyes by the end of their first week. Deer mice generally live for around 1 to 2 years in the wild but can live longer indoors with fewer predators and more resources.
Behaviors
Deer mice are nocturnal and active year-round. These rodents are known for their ability to climb and jump, making it easier to access food or find nesting spots. They are also excellent burrowers, creating intricate tunnels in the ground or soft materials. Deer mice typically avoid direct interaction with humans but will venture indoors for food or to escape extreme weather conditions.
Are Deer Mice Dangerous?
Most of the year, deer mice nest in quiet, dark, and undisturbed outdoor areas. When winter weather gets colder, they invade homes, garages, sheds, and sometimes even vehicles. Once inside, they are often in basements or attics. The biggest threat of deer mice is that they can transmit the dangerous—and potentially fatal—hantavirus. This disease is often transmitted through contact with mouse carcasses or breathing in air-borne urine droplets from infected deer mice.
How to Get Rid of Deer Mice?
If you suspect a deer mouse infestation, acting quickly to prevent further damage and reduce the risk of disease transmission is essential. One practical approach is to strategically place both snap and live traps in high-traffic areas, such as along walls or near nesting sites. Baiting with mouse bait stations can also help, but it’s essential to exercise caution to ensure pets and children are not harmed. Additionally, sealing entry points is crucial, as mice can squeeze through holes as small as a dime; be sure to address cracks and gaps in walls, foundations, doors, and windows. For larger infestations, contacting our professional rodent pest control service is advisable, as they can safely apply pesticides and set traps to eliminate deer mice from your home effectively.
Deer Mice Prevention Tips
Preventing deer mice from entering your home is much simpler than dealing with an active infestation. Start by sealing any entry points—use steel wool or caulk to block gaps around pipes, cracks in the foundation, or spaces under doors. Keeping your home clean is also crucial, so regularly wiping down kitchen counters, storing food in airtight containers, and ensuring crumbs or spills are promptly cleaned up. Decluttering can also help, so remove unnecessary piles of items like old newspapers, boxes, or unused furniture that could become nesting spots. If you store firewood, keep it at least 20 feet from your house, as it can provide shelter for deer mice. Finally, maintain your yard by trimming trees and shrubs away from the house and removing any potential outdoor hiding places, reducing the risk of mice indoors.
By following these tips, you can make your home less attractive to deer mice and prevent rodent infestation from happening.

FAQS
How Do You Tell If A Deer Mouse Has Hantavirus?
You cannot visually tell if a deer mouse carries Hantavirus, as infected mice show no apparent signs of illness. However, Hantavirus Pulmonary Syndrome (HPS) can be contracted when humans breathe in dust contaminated with the virus from deer mouse urine, droppings, or nesting materials. If deer mice are present in your home, taking precautions, such as wearing protective gear when cleaning and properly sanitizing affected areas, is essential.
How High Can A Deer Mouse Jump?
Deer mice are surprisingly agile and can jump up to 18 inches high. Their jumping ability and climbing and burrowing skills allow them to access food sources and nesting spots that seem out of reach.
What Do Deer Mouse Droppings Look Like?
Deer mouse droppings are small, dark, and shaped like rice grains. They are typically about 1/8 to 1/4 inch long and may be found near food sources or in areas where mice are active, such as along baseboards, attics, or kitchen cabinets. Handling or disturbing these droppings can pose health risks due to potential hantavirus contamination.
