White-footed mouse
Peromyscus leucopus
- Identification
- Very similar to the deer mouse — brownish above, white feet and underside. Difficult to tell apart without close inspection.
- Lifecycle & behavior
- Breeds spring through fall in wooded and edge habitats, entering homes and outbuildings in cooler months.
- When it's active in Central NY
- Abundant in the Finger Lakes' woods and field edges, and a key host for the blacklegged ticks that spread Lyme disease. Moves indoors in fall.
- Risk & damage
- Contaminates like other mice and, importantly, fuels the local tick cycle by hosting immature deer ticks — a public-health link specific to our region.
- Why DIY falls short
- Home methods don't address the outdoor habitat driving both the mouse and the tick pressure.
- How we treat it
- Trapping and exclusion, paired with tick-habitat reduction outdoors for properties with Lyme concerns.
White-footed mouse or deer mouse?
Practically indistinguishable in the field without close examination, and controlled the same way. Both are brown above with white bellies and feet and bicolored tails. What separates both of them from the house mouse is the clean white underside — a house mouse is dusty gray all the way around.
The white-footed mouse in Central New York
The white-footed mouse matters in this region for a reason that has nothing to do with buildings: it is one of the most important reservoirs for the bacterium that causes Lyme disease, and blacklegged tick larvae feeding on it are how many ticks become infected in the first place. In a region with substantial Lyme incidence, that connects rodent activity around a property to tick risk on it.
Around structures, they behave like deer mice — coming in from field and woodland edge, favoring outbuildings, and appearing in force in fall. Reducing harborage close to the house, keeping woodpiles and debris away from foundations, and sealing outbuildings all help on both fronts at once.

White-footed mouse — common questions
Is there a connection between mice and ticks on my property?
Yes, and it is direct. White-footed mice are a primary reservoir for the Lyme bacterium in the Northeast, and immature blacklegged ticks commonly acquire infection by feeding on them. Reducing rodent harborage near the house — woodpiles, debris, dense ground cover against the foundation — helps with both problems.
