Behavior and Habitat of House Mice

The House Mouse usually feeds on cereal grains, but it will eat other kinds of food. They are excellent climbers and have a keen sense of hearing, touch, taste, and smell. Droppings, fresh gnaw marks, and tracks indicate their presence. Contrary to rats, the house mouse does not need a free water source in order to survive. It will get all or most of its water from its food, if it is high in moisture.

The House mouse is found in and around homes and commercial structures, as well as in open fields and agricultural lands. They normally stay near a food source and establish a territory of 30 – 50 feet.

Signs of Infestation of House Mice

Look for droppings, footprints, teeth and gnaw marks, tunnels for nesting, and pay attention especially in the evening for gnawing and scratching sounds within the walls and running and possible squeaking sounds.

Tips for Prevention of House Mice

Seal all cracks, crevices, holes, and gaps larger than 1/4″ with cement or mixing compound. Remove all available food and harborage sources to deter mouse infestations.
