The adult House Mouse is small and slender about 1-2 inches long, excluding the tail. It has large round ears, a pointed nose and small eyes. Their tail is hairless and as long as the head and body combined. It’s fur is usually light grey or brown in colour.
The House Mouse, and sometimes the Long Tailed Field Mouse, seek the warmth and shelter of buildings for nesting sites and food. Their presence can usually be detected from sight dark coloured droppings or damage to food products, packaging or building fabric. Mice can also seriously damage water pipes, gas pipes and electric cables with many instances of electrical fires and floods attributed to them. They will also contaminate far more food than they consume and they are capable of carrying many diseases, particularly food poisoning.
The average House Mouse sheds 70 droppings in 24 hours and urinates frequently to mark its territory. Mice are erratic, sporadic feeders, nibbling at many sources of food rather than taking repeated meals from any one item. They do not need free water to drink as they normally obtain sufficient moisture from their food. Mice also climb well and can squeeze through very small gaps. These nibbling nuisances have a compulsive need to gnaw in order to keep their incisor teeth worn down to a constant length.
Mice become sexually mature in eight to ten weeks and a pair may produce eight litters each of 16 young, in a year. Multiply those numbers and you arrive at a horrifying number.
