What Do House Mice Eat?
In nature, mice prefer to eat cereal and seeds, but they will also eat insects, nuts and fruits. Inside structures, mice will consume almost any human food, but prefer grain based products.
Signs of an Infestation
There are a handful of ways to tell if house mice have made your home their own, including the following telltale signs of an infestation:
- Gnaw marks: Gnaw marks may be either rough or smooth.
- Droppings: House mouse droppings may be either soft and moist or dried and hard. The droppings measure about 1/8-1/4 inch long. They are rod shaped and pointed on the ends.
- Tracks: House mice leave 4-toed prints with their front feet and 5-toed prints with their hind feet.
- Rub marks: House mice often leave oily rub marks on walls along which they travel.
- Burrows: House mice burrow using nesting materials such as insulation.
- Runways: House mice usually use the same pathways. Active runways are sometimes visible, with rub marks, droppings, and footprints along them.
- Odor: The odor of house mouse urine may become distinct if there is a large number of house mice in a particular area. House mice use their strong-smelling urine to communicate with one another.
- Damaged goods: Mice prefer seeds or cereals but will readily eat insects trapped on glue boards.
- Actual rodent: If you see a mouse scurrying across the kitchen floor, there is likely a family of mice hiding out of sight.
