Types of Mice in Texas
Five types of mice show up around DFW homes. The house mouse is the one that lives and breeds indoors. White-footed mice and deer mice, often called field mice, come in from woods, creeks and grassland. Harvest mice and pygmy mice stay in weedy fields and rarely enter houses, though they live at the edges of many new neighborhoods.

Five Types of Mice Around DFW Homes
Texas Tech's Mammals of Texas, the standard reference on the state's wildlife, describes each of these species and where it lives. The table below sums up how to recognize them and how likely each one is to end up in your house.
| Mouse | How to spot it | Where you find it around DFW | Comes indoors? |
|---|---|---|---|
 House mouse |
Gray-brown, buff belly, scaly tail as long as its body | Homes, garages and sheds across the state | Yes all year |
| White-footed mouse |
Reddish-brown back, white belly and feet | Creek bottoms, wooded lots, brush piles | Often near woods |
| North American deermouse | White feet, tail sharply dark above and white below | Grassland and open brush | Old sheds and barns |
| Fulvous harvest mouse |
Orange-buff back, long tail, grooved front teeth | Weedy fields, fencerows, creek edges | Seldom |
| Northern pygmy mouse |
Tiny, about 4 inches with the tail | Grassy lots, old fields, roadsides | Rarely |
Field Mouse vs House Mouse
"Field mouse" usually means a white-footed mouse or a deer mouse. They are easy to tell from a house mouse once you know what to look for. Field mice are two-toned, brown or gray on top with a bright white belly and white feet, and they have big, dark eyes and large ears. A house mouse is one dull gray-brown color, with smaller eyes and a scaly, nearly hairless tail.
The tail helps too. A deer mouse's tail is sharply dark on top and white underneath, while a house mouse's tail is the same color all over. Up close, a house mouse also has a small notch in its upper front teeth, visible from the side, a detail the Mammals of Texas uses to identify it.
House Mice, the Year-Round Indoor Mouse
The house mouse isn't native to North America. It arrived through seaports and now lives across Texas, almost always close to people. Inside a house, it nests in wall voids, behind appliances and in stored boxes, and indoors it can breed in any season.
That's why house mice are the ones that turn up in kitchen drawers and pantries in any month. A mouse can slip through a gap the width of a dime, so a house that looks sealed often isn't.
White-Footed Mice and Deer Mice
White-footed mice are woodland mice, most common along creeks and river bottoms. In DFW, homes that back onto a greenbelt or a wooded creek see them most. They nest under logs, in brush piles and in buildings, and the Mammals of Texas notes that they often live close to people.
The North American deermouse prefers grassland and open brush and tends to move into old cabins and sheds. It is less common in eastern Texas, and its numbers appear to be falling in the north and center of the state. It matters because it is the main carrier of the hantavirus strain behind most U.S. cases.
The risk in Texas is low. The Texas DSHS hantavirus questions page explains how the virus spreads, and the state has confirmed only a few dozen cases since 1993. DSHS warns against sweeping or vacuuming mouse droppings and nests, since that puts the virus in the air. Spray them with disinfectant, let it soak, then wipe them up with gloves on.
Harvest Mice and Pygmy Mice in New Neighborhoods
The fulvous harvest mouse and the northern pygmy mouse live in tall grass and weeds. The harvest mouse often builds its nest above ground in a shrub, and the pygmy mouse, one of the smallest rodents in Texas, weighs less than half an ounce.
Both turn up where new subdivisions meet old pasture. The pygmy mouse has spread north over the past century into the Blackland Prairie and the Cross Timbers, two landscapes that DFW sits on. Texas Tech's account of the northern pygmy mouse traces that spread back to the early 1900s. Neither species usually moves indoors, though mowing a vacant lot or clearing a field can send them looking for new cover.
Keeping Mice Out of a DFW Home
The species changes how a mouse got in, not how to get it out. Our technicians seal the openings first, then trap the mice already inside, then place exterior bait stations that they maintain on regular visits. Gaps around AC lines, garage door corners and low openings around the foundation are the usual entry points.
If you're seeing droppings or hearing scratching at night, the first inspection inside the home is free. You can see how mouse control for DFW homes works step by step.
Texas Mice FAQ
What type of mice infest homes in Texas?
The house mouse is the main indoor mouse in Texas, and it can live inside a home year-round. White-footed mice and deer mice come in less often, usually from wooded or grassy land next to the house.
Which mice carry hantavirus in Texas?
The North American deermouse is the main carrier in the U.S. Texas Tech also advises handling white-footed mice with caution. Cases in Texas are rare, and exposure often comes from stirring up dust while cleaning a rodent-filled barn or shed.
Do field mice come inside in winter?
Some do. White-footed mice that live near woods or creeks may move into garages and sheds when it turns cold, and they can nest in any building with an opening.
