Mice

                

 
 
 
The house mouse (Mus musculus musculus & Mus musculus domesticu) are about 6-9cm long with a tail 8-10 cm long and weighing approximately 25-30g. They vary in colour through grey to brown.
 
 
 
 
 

A mouse does not need to drink and absorbs enough moisture from its food to survive. They have excellent hearing but poor vision beyond a few feet. They are very sensitive to motion and can detect movement to about 30-50 feet away.

 

 
They have a highly developed sense of touch through their hair and whiskers and use this to find their way around. They also use their sense of smell and leave scent marks showing the way to food, shelter etc. Mice tend to travel along wall/floor junctions as they prefer to have a solid object to one side of them.
 
 
 

 

They are very agile and excellent climbers, they can fit through gaps of about 6mm. Mice are generally nocturnal but will be seen during daylight hours if disturbed.
 
 
 
 
 
 
 
 
 
 
In ideal conditions a pair of mice can produce 2000 offspring in a year, they are pregnant for only 21 days and it is the availability of food and shelter that dictates the size of an infestation.

 

 

 
 
A mouse will only need 5g of food a day and they eat little and often. They have strong teeth and can gnaw through plastic and wood so a cardboard box is little deterrent.
 

 

Mice are also incontinent as they move they dribble urine and leave droppings so the risk of contamination is high, they can carry the salmonella bacteria that can be passed on to people through food or food surfaces that they contaminate.
 
 
 
Mice can also be very destructive to electrical wiring by gnawing on the plastic coating.
