Rodents have been one of man's greatest enemies since the beginning of time. In the middle ages they ravaged Europe with the "Black" plaque. Most rodents live in close contact to humans, and as a result, have spread throughout the world. Most carry pathogenic (harmful) organisms such as Salmonella bacteria which when deposited on food preparation surfaces or on food itself can cause food poisoning. Today, they have brought entire cities to their knees by gnawing through communication cable. In fact, the gnawing instinct is so strong within rodents that believe it or not, some rodents can even chew on concrete. If they gnaw an opening as small as 62mm for mice and 125mm for rats, they can make a burrow within the deepest crevice of your home. To make matters worse, rodents reproduce rapidly. A couple of mice in your home or business today can mean several dozen within an extremely short period of time. They can be very destructive through their constant gnawing.
Rodents are choosy and won’t take mouldy food they have a highly developed sense of smell and taste and will initially reject anything unfamiliar. They can develop bait shyness – once a negative experience is communicated to other group members, they will avoid the bait.
Rodents know their territory well and know were to find food and water. Rodents can walk/run against horizontal and vertical lines and pipes, bricks or other rough surfaces.
Rodents don’t vomit.
Rats often kill and eat house mice. This behaviour is called Muricide.
The house mouse appears to have originated in Central Asia. As it is much smaller the house mouse should not be confused with the two rat species. House mice are light, intermittent and erratic feeders, tending to sample from a large number of different sites. They can survive on a relatively poor diet and without water, provided their food supply is moist.
Mice are very good breeders. In ideal conditions the female house mouse can become sexually mature at only six weeks old, and can have a litter of between 4-8 every month. Mice are carriers of pathogenic (harmful) organisms such as Salmonella bacteria which when deposited on food preparation surfaces or on food itself can cause food poisoning.
Mice can cause serious damage to property through their constant gnawing. As well as damaging consumable and non-consumable goods they can also cause fires or flooding by gnawing through wiring, cables and pipes.
Successful control relies on a good knowledge of the pest and its habits. Unless you know what you are doing mice can actually outbreed most trapping laid by home owners.
Brown rat, Norway rat, common rat, has been bred for research and the pet trade. They spread across the world via the shipping traffic from foreign countries in the 18th Century, largely replacing the black rat. Along with house mice, they are considered to be the most widespread terrestrial mammal. They live up to 18 months in the wild. Brown rats swim well and are sometimes mistaken for water voles. Rats have well-developed senses of hearing and smell. Brown rats breed throughout the year and can produce five litters a year. Females give birth to an average of eight young, within 22-24 days. rats sizes vary but are normally between 20cm - 27cm
The Roof rat is also called the black rat, house rat or ship rat, as its name suggests was commonly found on ships, resulting in their world wide distribution. Black rats are very similar in appearance to brown rats, but they are generally slimmer, with larger ears and a longer tail. Black rats are highly adaptable and can be found in a variety of habitats, typically near human habituation. They are subject to persistent pest control due to the damage they cause and the numerous diseases they spread, including bubonic plague, typhus and rabies.
