Rats (Rattus spp.) have caused more human suffering and more economic damage than any other vertebrate pest. From causing plague epidemics (the "Black Death" of Europe) to rat-bite fever, whether feeding on stored grain or gnawing electric wires, rats are enemies of humankind.

Identify a rat problem

Norway rats are the most known, as they are prominent in each state.


Norway rats have a stocky build and are gray-brown in color. They have small eyes and ears, and a tail shorter than the rest of their body. They can grow to be up to 10 inches long and weigh 9-12 ounces, depending on the sex. Norway rats are also known as the brown rat, sewer rat, and common rat.

Signs of Rat Infestation

Generally, customers notice signs of infestations long before they see an actual rat. Signs of a rat infestation may include:


Rats prefer to nest around warm, dry, and out of the way places. Common areas include unused dresser drawers, boxes, and inside cabinets.


Rat droppings are rice shaped and dark in color. During an infestation, droppings can be found along baseboards and in dark corners. Urine trails or puddles are often identifiable. With almost every step, rats dribble urine that leaves a terrible musty scent.

Grease Markings

When rats travel through or on surfaces the oils and dirt on their fur leaves behind a greasy stain.


Rats constantly chew in order to keep the size of their incisors under control. Their favorite material to gnaw on is wood, leaving behind obvious gnaw marks, sawdust, and small chunks of wood.

Food items should be inspected thoroughly if a rat infestation is suspected. Rats will chew through food containers and contaminate food within cupboards, pantries, and even your pet food!


If you have a rat infestation, the sound will be irritable. You will hear scurrying across the ceiling, scratching within walls, and gnawing throughout your home. If your pet begins to act on alert and paying extra attention to baseboards, they may be hearing noises you are not!

Rat Damage

Rats cause extensive damages throughout your home and can cause a variety of hazards. Wiring gets chewed and nests will be built in spots that cause fire hazards. While looking for food and running across countertops and digging through pantries, rats will contaminate food and create and unhealthy hazard in your kitchen.
