Pest Identification

RODENTS

Most rodent problems involve one of three common rodent pests... house mice, Norway rats or roof rats. While they are all rodents, each has its own unique physical characteristics and behavior. Therefore, the first step in addressing a rodent problem is to correctly identify the pest species you are dealing with.

House Mouse - "The Invader"

Scientific Name: Mus musculus
The house mouse is easy to recognize, generally 16-18 cm in length and black or dusty gray in color. It is a nibbler. Inquisitive, though it stays close to its nest, which is typically 10-30 ft from a food and water source. Mice typically make their nests from string, shredded paper or straw. Its food preferences include grains, cereals, meats, fish, etc.

Norway Rat - "The Burrower"

Scientific Name: Rattus Norvegicus
The Norway rat is a large rodent, usually 30-45 cm in length, weighing 10-17 ounces with reddish brown fur. Norway rats typically nest in burrows 90-450 ft from a food and water source. With its powerful front teeth, a Norway rat can gnaw through wood, electrical cables, pipes and other objects. It is very suspicious of anything new in its environment. Its food preferences include grains, meats, fish, almost anything.


Roof Rat - "The Climber"

Scientific Name: Rattus rattus
The black roof rat is smaller, weighing 6-9 ounces, has a thin body, pointy nose, large ears and tail, and is dark gray in color. It nests in trees/rooftops 100-300 ft from a food or water source. Its food preferences include fruits, vegetables, grains and seeds.

 

Other key indicators of activity include hair and gnaw marks and nests. Look for signs of activity in dark shadowy areas where rodents travel.

MOLES

Moles are an ancient species of mammals that are well adapted to their life underground. With their powerful forelimbs, moles excavate through the ground in search of food. These industrious creatures can tunnel up to 100 feet per day, causing significant damage above ground.

To fuel this high energy lifestyle, moles require vast quantities of high protein foods. They consume grubs and insects but their favorite food is the earthworm. Contrary to popular belief, moles do not eat plants, roots or bulbs.

Moles live underground most of their lives. Moles seen on the surface are most often juveniles, forced from their mother's nest and moving to establish their own tunnel system.
