The house mouse is a small, slender rodent that has a slightly pointed nose; small, black, protruding eyes; large, hairy ears, and a nearly hairless tail with obvious scale rings. The adult mouse weighs about 20 grams. They are generally greyish-brown.

Mice may breed year-round and a female can have 5–10 litters per year. Sexual maturity is reached in just 6 weeks and figures show that one breeding pair can be responsible for producing up to 2000 offspring in a year.
House mice live in and around homes and farms, as well as in open fields and agricultural lands. Twenty per cent of Australian homes have rodent problems and 60% of these have recurring problems.

The onset of cold weather in temperate regions causes mice to move inside in search of shelter and food. They eat many types of food but prefer seeds and grain. They are not hesitant to sample new foods and are considered "nibblers", sampling many kinds of food that may exist in their environment. Foods high in fat, protein, or sugar may be preferred even when grain and seed also are present. Such items include bacon, chocolate, butter and nuts. A single mouse eats only about 3 grams of food per day but because of their habit of nibbling on many foods and discarding partially eaten items, mice destroy significantly more food than they consume.
