All About Mice

The house mouse is just about what you’d expect a mouse to be – small (5 to 7cm), grey-brown, with an almost naked tail as long or longer than its body and weighing less than 28 grams. The mouse, however, can eat about one-tenth of its weight each day. As you may guess with the name house mouse, these creatures prefer life indoors, whether it be an apartment complex or single-family dwelling. They prefer the comfort of niches between walls and behind cabinets and appliances. The house mouse has a very prolific reproductive system breeding year-round and having as many as eight litters annually. Females can start having their litters at the age of one and a half to two months. Life expectancy for a wild mouse is no more than one year. Mice have a diet of a variety of foods, such as seeds, grains and nuts requiring only about 2 grams of food each day, and can live without access to fresh water if their solid food is moist.

Mouse Problems

Contamination of Food

One of the main problems faced from having a mouse in your house is their contamination of food with their urine and faeces. Their gnawing on wood, paper, cloth, books and insulation on wiring can also pose a real threat for any homeowner. This can be noted by observing gnawing leaves paired tooth marks about 3mm wide and seeing droppings which are rod-shaped and about 6 to 8mm long. Mice can also consume considerable quantities of stored seed and grains from farmers and granaries.


Mice can carry a wide variety of diseases transmissible to humans. A very real problem with the infestation of mice is the hantavirus which has been a threat in the arid southwestern part of the country. Another major concern is salmonellosis which is transmitted by mice and is a concern in food storage and preparation areas.

House Mouse Species

Nests in wall voids, in undisturbed debris, or outdoors. Eats grains, bird seed, dry pet food, but will eat anything, even soap and leather if no other food is available. Generally, stays within 3-9 metres of nest. Doesn’t like open spaces.
