House Mouse


Small and slender, 3 to 4 inches long, with large ears, small eyes and pointed nose. Light brown or light gray. Droppings are rod-shaped.


Mice live everywhere outside, and are found more often indoors than rats because they are smaller and more able to fit through small openings. Mice can fit through a crack or hole 1/4 of an inch or larger—about the width of a pencil. Their territory generally ranges 10 to 30 feet from their nest. They are curious but wary. They are also excellent climbers, making rodent control difficult. They can enter your home through holes in soffit vents, around cables entering the building, and through turbines and box vents on the roof.


Omnivorous, but prefers seeds and cereal grains.

Insect control: house mice

Effective rodent control involves sealing as many holes and cracks as possible in the outside of your home. Keep firewood stored as far from the home as possible and store it off the ground. Remove piles of debris, stones, bricks and leaves near your home’s foundation. Stuff large holes or cracks in your foundation with steel wool or wire mesh before sealing with caulk or foam—otherwise mice could chew through. And since mice can slip under many garage doors, don’t forget to tightly seal the door from the garage to the house.

To locate existing nests and eliminate mice already in your home, professional rodent control materials such as baits and traps are usually needed.
