Are Norway Rats Dangerous?

Written by Aptive Pest Control August 27, 2024

Norway rats, also known as brown rats, are unwelcome guests in any home. While they might not chase you down like in horror movies, these persistent rodents pose a significant threat to your health, property, and peace of mind.

This article explores the potential dangers associated with Norway rats, along with practical steps you can take to mitigate these risks and safeguard your home.

Health Risks from Norway Rats

Norway rats are not simply creepy; they can be carriers of several diseases that can be passed on to humans. These diseases can be transmitted through direct contact with the rat, its droppings, or even by inhaling airborne dust particles contaminated with rat urine or feces.

Here’s a closer look at some of the potential health dangers of rat infestations:

  • Leptospirosis: This bacterial infection can cause a range of symptoms, including fever, headache, muscle aches, and diarrhea. In severe cases, it can lead to kidney failure or meningitis.
  • Hantavirus Pulmonary Syndrome: This potentially fatal respiratory illness can develop after inhaling dust tainted with rat droppings or urine. Early symptoms resemble the common cold but can progress to difficulty breathing and even death.
  • Rat-Bite Fever: This bacterial infection can cause fever, chills, vomiting, and muscle pain. While uncommon, it can lead to severe complications if left untreated.
  • Salmonella: Norway rats can carry this bacteria, which can contaminate food or surfaces and cause foodborne illness. Symptoms include diarrhea, vomiting, and abdominal cramps.

Property Damage Caused by Norway Rats

Beyond the health risks, Norway rats are notorious for causing significant property damage. Their sharp incisors constantly grow, and they gnaw on virtually anything to keep them at a manageable length. This includes:

  • Wiring: Chewed electrical wires pose a serious fire hazard.
  • Pipes: Rodents can gnaw through water pipes, leading to leaks and potential water damage.
  • Walls and Insulation: Rats can burrow through walls and insulation, creating entry points and compromising the structural integrity of your home.
  • Furniture and Belongings: No object is safe from a Norway rat’s gnawing, including furniture, books, and personal belongings.

Protecting Your Home from Norway Rats

Fortunately, several measures can be taken to remove Norway rats and mitigate the risks they pose:

  • Seal Entry Points: Inspect your home for potential entry points, such as cracks around pipes, gaps around doors, and damaged weather stripping. Seal these openings with caulk or other appropriate materials.
  • Eliminate Food Sources: Store food in airtight containers and avoid leaving crumbs or spills on countertops. Secure garbage cans with tight-fitting lids and empty them regularly.
  • Address Potential Hiding Spots: Minimize clutter inside and outside your home, as rats like to nest in dark, secluded areas. Regularly trim bushes and vegetation near your foundation.
  • Set Traps: If you suspect an active infestation, consider setting snap traps or bait stations in strategic locations. However, be cautious if you have pets or small children in the house. Most professionals will dissuade from using poison inside a home, as it can be problematic dealing with rodent carcasses if they make it into walls or ceilings. It’s always best to leave trapping up to the professionals.
