How To Identify Rats

There are two common species of rats that invade and cause problems in structures.   They are the Norway rat and the roof rat.

Norway Rats
Adults grow to between 10-12 inches in length including their tail. Their tail is shorter than their body. They are brownish gray in color and their body is long and heavily built. Norway rats are not good at climbing and are therefore mostly found in basements and on the first floor of buildings.

Roof Rats
Roof rats are smaller and have a thinner lighter build than the Norway rat. Their tails are long than their bodies. Roof rats are dark brown or black and have a contrasting lighter colored underbelly. Roof rats excel at climbing and are often found in attics and in the higher levels of homes and other buildings.

Why Do I Have A Rat Problem?

Rats live near humans because they need access to food and shelter.  If a structure has openings that rats can squeeze through and provides the elements they need to survive, you can be sure they'll infest.

Are Rats Dangerous?

Yes, rats are dangerous. They may carry many dangerous diseases that include murine typhus, leptospirosis and salmonellosis; rats will also contaminate buildings with their urine and feces. They will introduce parasites including fleas, ticks, and mites.

Inside rats damage the building’s structure by chewing through wires, pipes, insulation, and drywall. Some rats even burrow underneath of foundations which can cause major structural damage. They can also destroy personal items like pictures, furniture, flooring, and clothing.  In commercial setting, rats contaminate and/or damage product and may have a negative impact on business.
