    What are Norway Rats?

    The Norway rat, commonly referred to as the street or sewer rat, is believed to be of Asian origin, arriving in the U.S. on ships from other countries in the 1700s. Today, Norway rats are found throughout the world. They have poor vision and are colorblind. Their other senses, including hearing, smell, touch and taste make up for their bad vision. They are capable of running, climbing, jumping and swimming. These rats are known to cause damage to properties and structures through their gnawing.

    “I called Pest Management Systems, Inc. requesting information about pest services concerning a particular insect I was seeing in my rental property. The receptionist was very knowledgeable concerning the insect with regards to how they breed and their season for egg hatching. She also advised me of alternative approaches to handle the situation. I really appreciate the fact that Pest Management Systems, Inc. did not attempt to sell a service that probably would not have provided the results I wished (like other popular pest control companies in my area attempted to do). I will definitely consider Pest Management Systems, Inc. in the near future. ”

    Signs of a Norway Rat Infestation

    Gnaw marks anywhere in the home are a good indication of rat activity. Spotting droppings, which are capsule-shaped, is another key indicator of a rat problem. Norway rats’ droppings have blunt ends, while those of roof rats have pointed ends. Other signs include footprints, greasy and dark rub marks from oily fur against pathways, burrows, runways with stacked food, and damaged or rummaged-through food products.

    How to Prevent Norway Rats

    Norway rats can reproduce quickly, giving birth to about three to six litters each year. This makes it all the more important to take proactive measures, such as Norway rat control, to prevent an infestation from taking root.

    These rats are often drawn to piles of wood, so homeowners should keep firewood stored well away from the structure and remove debris piles to reduce ideal nesting spots. It is also important to seal any holes on the outside of the home with gnaw-proof material to block potential points of entry. It is best to eliminate sources of moisture like leaky pipes, especially in crawl spaces and basements, as the dampness can attract rats in search of drinking water. Also eliminate potential sources of food, such as garbage, dog food, bird seed, etc. If you see signs of a Norway Rat infestation, please call PMi.

    How to Get Rid of Norway Rats

    The safest and most effective way for homeowners to get rid of Norway rats is to work with a professional. PMi can help with these infestations.

    Threats

    Thanks to their propensity to gnaw through almost anything, Norway rats can cause damage to properties and structures, making them a threat to homeowners. Equally important, these rats are carriers of serious diseases, including jaundice, rat-bite fever, cowpox, trichinosis, and salmonellosis. Rats also pose other health threats, as they can contaminate food and introduce fleas into a home.
