The house mouse, mostly brownish grey in colour, has an excellent sense of hearing, smell and taste, but has poor sight and is colour blind.

The house mouse can burrow, live indoors and outdoors. 

They carry diseases such as Salmonella, and can transmit a type of Leptospirosis, but not Weil's disease. Their continual dribble of urine contaminates food and feedstuffs. They are a particular problem in grain stores, warehouses, shops, hospitals and even domestic premises.

They can enter a new location through gaps as small as 6mm, building hard to find nests, and populate an area with new colonies quickly and with devastating effect.


The mouse:

  • Weighs approximately 15 grams and is 60-90mm from head to body.
  • The life cycle of the house mouse is 9-12 months, reaching sexual maturity at around 6 weeks.
  • Litter size: 5-6 offspring with a reproduction rate of 8 litters per year.

Control Methods

Mice are more of a problem in buildings because they are liable to cause fires by gnawing cables, cause damage to insulation resulting in costly heating bills and expensive replacement.

Traditional methods such as mouse traps have limited effect on mice infestations. Poisons available from stores, if used strictly in adherence with label directions, are more effective.
