Mammal
White-footed Mouse
Peromyscus leucopusAlso known as Woodmouse, White-footed Deermouse
White-footed mice are nocturnal, agile climbers that navigate forest understories and low tree branches using their long tails for balance. They build globular nests of woven leaves, bark, and shredded plant material in tree cavities, abandoned bird nests, or stone walls. As key seed dispersers and major hosts for blacklegged ticks, they play a central role in eastern North American forest ecosystems.

- Very high
- Why interaction risk is moderate
- Primary reservoir host for Lyme disease and tick vector; avoid handling wild mice or their droppings.
- Why it is dangerous
- Serves as the primary reservoir for Lyme disease bacteria and can transmit hantavirus through dried droppings or urine.
- How to recognize a risky encounter
- Look for a reddish-brown back, sharply contrasting bright white belly and feet, and large prominent ears.
- What to do
- Avoid physical contact and wear a mask when cleaning up nesting materials or droppings in enclosed spaces.
Responsible observation
- Observation: Look for active mice along tree limbs or near woodpiles at night using a red flashlight beam.
- Sanitation: Keep food stored in airtight containers and seal house entry points to prevent indoor nesting.
- Safety: Avoid handling wild rodents or sweeping dry nesting areas without proper respiratory protection.
