A little bit about Mice . . .
Mice will frequently infest human structures such as homes and storage units, seeking food and shelter. These intruders create a nuisance due to noise, destructive eating and nesting habits, and a potential health threat as the carriers of disease.
Mice are covered with hair, and have short legs and a hairless, but soft looking, tail. When moving, a mouse's long body can be seen. However, when stationary, mice tend to look squat. Their front feet have 4 toes, while their hind ones have 5. A mouse's teeth are comprised of molars and chisel-like incisors, with a gap of space due to an absence of canine teeth.
Since mice are nocturnal and shy from human activity, it is common for people to discover droppings before sighting the actual mouse. Mouse droppings are rod or pellet shaped, 1/8"-1/4" long and generally brown in color.
While making their nests, mice seek a great variety of materials and can cause severe damage to upholstered items and paper products in the process. However, it is the potential spread of disease that creates the greatest concern.
Mice are known to spread Salmonella and tapeworm through their droppings, as well as carry ticks and mites infected with other agents. Depending on the species of mouse, there are also other disease concerns.
A little bit About Rats . . .
Rats that infest human structures in Perth create a nuisance due to noise, destructive eating and nesting habits, and a potential health threat as the carriers of disease.
Rats are covered with hair, and have long bodies, short legs, and a hairless tail. Their front feet have four toes, while their hind ones have five. A rat's teeth are comprised of molars and chisel-like incisors, with a gap of space due to an absence of canine teeth. The largest common rat in the Australia is the sewer rat, which is usually between seven and nine and a half inches long.
Approximately 20% of the world's food supply is lost to rat consumption or contamination. For example, the cotton rat is an agricultural pest that causes damage to crops and invades structures storing plant material.
Rats also pose a great threat as the carriers and spreaders of disease. Depending on the species, a rat may carry the Black Creek Canal Virus, infectious jaundice, rat bite fever, and salmonellosis.
Rats are generally considered to be highly prolific breeders. Depending on the species, a rat can reach sexual maturity at as early as six weeks old.
Female rats gestate their litters internally, giving birth to live young who are then nourished with milk. Although born hairless and blind, young rats are generally independent within one month.
A rat will rarely live beyond one year in the wild.
The majority of rats are nocturnal and active year round. They are generally shy creatures, usually with poor vision. Depending on the species, nests can be found both in upper parts of structures and in the ground.
Some rats, such as the black rat, are excellent runners, jumpers, and are even able to swim.
