Common types of rodents in New Jersey
Rodents are a type of mammal that has front incisors which continuously grow. Found living around the world, rodents are able to survive in a variety of climates and most types of living conditions. Their ability to thrive is due in part to their reliance on people for their basic needs which are food, water, and shelter. Because of this, keeping rodents out of your home or business can be very difficult, but is necessary because of their ability to introduce health risks and cause structural damages. In our area, the types of rodents that are most commonly found invading homes are the roof rat, Norway rat, house mouse, and white-footed mouse.
Roof rats are dark brown or black in color with some gray hairs sprinkled about; their underbellies are lighter in color. Roof rats can be identified by their pointed noses, large dark eyes, and large ears. They have long, thin bodies. Their slim build allows them to easily climb trees and gain access to the roofs of homes. The bodies of these rodents grow up 8 and their long scaly tails add another 6-8 inches to their total length.
Norway rats have brown fur peppered with black hairs, lighter colored underbellies, and bi-colored tails. They have blunt noses, protruding small black eyes, and small ears. Adult Norway rats have long “heavy” bodies that grow up to 9 ½ inches in length; their tails add another 6 to 8 inches to their total body length. Larger than roof rats, they also lack the agility and climbing abilities that roof rats possess. Norway rats typically infest basements and lower levels of buildings.
As their name suggests, the house mouse is the most common species of mouse that is found invading homes. These mice can be identified by their small, slender bodies, long tails, large ears, and small dark beady eyes. They typically grow up 3 ¾ inches in length but when you include their tails in that measurement, their total length can reach almost 8 inches. Their tail and ears are both covered with a layer of soft velvety fur. Their fur can vary in color from grayish-brown to dark gray or black in color; they have a lighter colored belly that is usually tan or whitish in color.
The white-footed mouse is mainly associated with rural areas and is commonly found living in and around wooded areas; they are native to North America. They are small mice that grow between 6 and 7 ½ inches in length, including their tails. White-footed mice have large ears covered with tufts of hair, brown eyes, vary in color depending on the time of the year. They do have a distinctive dark line running down the middle of their backs. While you may find white-footed mice inside, they aren’t typically nesting inside but rather foraging for food.
Where do rodents nest?
Outside, roof rats nest trees, woodpiles, dense vegetation, and piles of debris. Inside they like to nest in the upper levels of buildings including attics and in ceilings. Norway rats, in contrast, are more likely to be found nesting in the basement of homes or behind the walls of the ground floor. Outside, Norway rats burrow and nest underneath of buildings, concrete slabs, in garbage dumps, and along the banks of streams, ponds, and lakes. As you can imagine, house mice are more often than not found nesting inside of homes behind walls, underneath flooring, behind appliances, in crawl spaces, and in the basement or attic. The white-footed mouse is more likely to be found nesting outside rather than inside of a home. They nest in hollow trees, under piles of debris, in abandoned bird’s nests, and inside barns and other outbuildings.
Why do I have a rodent problem?
If you’ve discovered rodents in your home or office, it’s likely they found a way in and their happy with food and water sources as well as the options for safe shelter. Outside, they may be attracted to open garbage cans or dumpsters, gardens, compost piles, fruit trees, bird feeders, and pet food. It is also said that rats love dog feces.
Are rodents dangerous?
Yes, rodents are considered to be dangerous. They constantly chew to keep their incisors at a reasonable length. Unfortunately, this means that electrical wires, lumber, insulation, drywall, and other building materials as well as personal belongings may be chewed on by these pests, creating significant damage. They also contaminate surfaces and items with their urine and droppings.
In addition to causing damages rodents can transmit a wide variety of diseases and bacteria to people. White-footed mice are carriers of Borrelia burgorferi, the bacteria that causes Lyme disease, these mice are typically the first blood meal for black-legged ticks, who then transmit the disease to people. Other diseases that rodents can spread include: Lymphocytic choriomeningitis (LCM), salmonellosis, dysentery, Hantavirus, and leptospirosis
