The deer mouse is one of the pests that like to take up residency in one’s home and property. Here are some facts for homeowners to know in order to identify possible deer mouse infestations:
Deer Mouse Mating Behavior
The deer mouse mating seasons occurs from spring until fall, with a slowdown in the summer, but in warmer climates deer mice can produce year round. The gestation period is 21 to 23 days, and a couple is able to have 2 to 4 litters a year, with litter sizes range from 3 to 5 young. Deer mice usually mate together for life, so a single parenting pair is capable of producing 6 to 20 offspring in a single year. That’s a whole lot of babies!
Living Environment & Diet of a Deer Mouse
A couple will commonly live in a nest made of twigs, leaves, grass, and other accessible fibrous materials. They may also be lined with fur, feathers, or shredded cloth. Deer mice typically build their nests underground beneath roots of trees or shrubs, beneath logs, or will simply take up residency in another burrow made by another rodent. They’ve even been known to live in hollowed logs, fence posts, cupboards, and furniture of unoccupied buildings, making them an entire species of squatters.
A deer mouse’s diet is primarily of seeds, and they’ll go for nuts, acorns, and other similar food sources. They’re also known to consume fruits, insects and insect larvae, fungi, and some green vegetation. Deer mice are also known to create food hoards in or near their nest sites when their food sources are in abundance, such as the fall.
