Nobody wants rats and mice in their property. Rodents are able to survive in most conditions, both inside and outside. Their habitation is based strictly on the availability of food and harbor ages. Rodents are some of the most adaptable mammals around, and their ability to feed on many different types of food allows them to survive in any environment. They reproduce quickly, and their sophisticated behavior patterns give them the ability to avoid the dangers of potential enemies. The identification and sealing of entry points as well as good sanitation is important in the elimination of rodent infestation. Remember mice can enter openings as small as 1/4 inch and 3/8 - 1/2 inch for rats.Rats are nocturnal in nature and if you actually see them then you have a serious problem. They spread disease, damage structures, and contaminate food animal feed, and the environment around them. A single rat will produce 25,000 droppings per ear and will also shed more than one million body hairs each year. The physical damage to structures which can include electrical, plumbing, and woodwork problems can be extensive and costly.
Also known as the brown rat, gray rat, common rat, house rat, wharf rat, sewer rat, barn rat, and water rat, they are actually not from Norway but were first identified there. They are able to gnaw through wood, lead aluminum, copper, cinder block, and uncured concrete. They burrow extensively in soil and are excellent swimmers and good climbers. They are nocturnal, most of their activity and feeding takes place between a half-hour after sunset and a half-hour before sunrise.
Life Cycle / Life Span
Adults only live from 9-12 months.
They usually nest in the basements and lower portions of buildings.
They are omnivores so they can eat just about anything but prefer meats, fish, flour, cereal grains, fruits, vegetables. They will eat almost any human food and garbage. They consume ¾ to an ounce of food each day and require water daily to survive from ½ to 1 ounce of water every day.
Norway rats will become sexually mature in 3-5 months of age. The females create a nest in secluded places when inside a building, o in burrows or tunnels when outside. There can be from four to sever litters each year, with up to a dozen young in each litter, so the population can grow quite rapidly.Each nest can produce as many as 200 wasps over the summer.
Often completely black, but can also be grayish brown, and may
vary from a pure gray to a blackish or reddish brown. The underside
is usually gray to yellow white. The body is heavy and thick, from
7-10 inches long. The tail is shorter than the head and body
about 6 to 8 1/8 inches long. The tail is dark on top with a lighter underside.
They are probably the most common rat species found, also known as Alexandrian rats, black rats, fruit rats, and ship rats. Most of their activity is at night because they are nocturnal.
Life Cycle / Life Span
About 1 year
Trees, ground, over upper portions of buildings.
They are omnivores, they eat snails, fruits, grains, vegetables, nuts and seeds, pet food from unsealed garbage containers and just about anything leftover from humans. They usually consume ½ to 1 ounce of food daily and drink up to 1 ounce of water daily.
The female Roof rat reaches sexual maturity at 3 months of age. They are in heat approximately every 4-5 days. The gestation period is 21 to 23 das, with each litter being 5-8 pups. After giving birth the female is capable of being in heat again in 24 to 48 hours, so many generations can be produced each year.
The body is 6 ½ to 8 inches long and are black to brownish gray, with the
underside being gray to white. The tail is hairless and longer than the
head and body, from 71/2 to 10 inches long.
