Brown Rat, Common Rat , Norway Rat, Sewer Rat, Rattus Norvegicus
Rats are typically distinguished from mice by their size; rats are generally large rodents, while mice are generally small rodents. The best-known rat species are the Black Rat (Rattus Rattus) and the Brown Rat (Rattus Norvegicus) which is the most common of the rats that we are asked to deal with. In Western countries, many people keep domesticated rats as pets. These are of the species Rattus Norvegicus, which originated in the grasslands of China and spread to Europe and eventually, in 1775, to the New World.Rats have keen taste, hearing, and sense of smell. They will climb to find food or shelter, and they can gain entrance to a building through any opening larger than 1/2 inch across. Rats can swim. Rats are creatures of habit that prefer using the same passageways over and over. They are also wearily of anything new in their environment. Rats are usually nocturnal and have poor eyesight. These social animals live in hierarchical groups and like to nest in burrows.
A rats fur is coarse and usually brown or dark grey, while the under parts are lighter grey or brown. The length can be up to 25 cm (10 in), with the tail a further 25 cm (10 in), the same length as the body. Adult body weight averages 350 g (12 oz) in males and about 250 g (9 oz) in females, but a very large individual can reach 500 g (18 oz). Rats weighing over 1 kg (2.2 lb) are exceptional, and stories of rats as big as cats are exaggerations, or misidentifications of other rodents such as the coypu and muskrat.
A rat can tread water for three days and survive being flushed down the toilet and it can return to the building via the same route
Rats will normally be found in burrows outside, under garden sheds or located near rubbish. Inside you will find them under kitchen units, in basements, behind bath panels and in roof voids to name just a few places.
Apart from sightings the most usual signs are droppings, evidence of scratching, gnawing, tracks, burrows etc
They are a serious risk to public health. Apart from the physical contamination of surfaces and food with their droppings and urine they spread diseases such as salmonellosis (food poisoning), and Leptospirosis (Weils’ disease).It is because of this that an infestation of rats should not be tolerated.
