Where do Norway rats nest?

Are Norway rats dangerous?

Yes, Norway rats are dangerous.  They expose people to disease and bacteria including plague, jaundice, rat-bite fever, and salmonellosis.  Norway rats may introduce fleas, ticks and mites as well.   

Damages caused by Norway rats

A Norway rat infestation can lead to extensive damage to structures and belongings.  Like other rodents, Norway rats have front incisors that continuously grow.  In order to prevent overgrowth, they gnaw constantly.  In a home or business, they often chew on wires, pipes, drywall and insulation, other building material and furniture as well as clothing, books and personal belongings.  Their nesting and foraging habits are also destructive as they contaminate spaces with their rat droppings and urine. 

Norway rat control

Norway rats are difficult to exterminate in homes and businesses without the help of professional rodent control specialists.  DIY rodent control is ineffective because it typically does not address the root of the infestation.  At Pine State Pest Solutions, we offer effective rodent control and management plans for both residential and commercial environments in our Maine service area.
