Rats are a world wide pest, spreading disease and causing structural damage. The Norway Rat is most commonly found in Europe. A less commonly found species is the Black Rat and is largely restricted to port areas. Mice have a lot in common with the rat, but differences in it’s biology and behaviour are the key to effective control. They are rarely found in sewers as they prefer to live indoors, causing damage to buildings. Fur colour is brownish grey but lighter shades occur. Excellent sense of hearing, taste and smell. They have poor eyesight and are colour-blind. Life span is approx. 9/12 months and they are sexually mature at the age of 6 weeks. They have up to 8 litters a year, with each producing between 5/6 offspring. Wasps are regarded as nuisance pests or a threat to health. They can become a problem when they enter premises handling food. Foodstuffs can become contaminated and people may be stung. Up to 30mm long, eyes are kidney shaped. They have two pairs of wings, hind wings being smaller than the fore wings and their mouth parts are adapted for chewing and licking. The abdomen is constricted at the base giving the impression of a waist.
