Are Norway Rats Dangerous?

Yes! The CDC states that Norway rats can expose humans to very serious diseases and bacteria including plague, rat-bite fever, salmonellosis, hantavirus, Seoul virus, and more!

These diseases are spread mostly through the rat's hair, urine, droppings, saliva, and dust created by them as well as through the contamination of food and cookware.

Therefore, care should be taken to avoid contact with any rat-infected materials.

Damage Caused by Norway Rats

A Norway rat infestation can lead to serious damage to structures and belongings. It's important to understand that rats have front incisors which continuously grow and so must be worn down by gnawing on hard surfaces.

Given that our homes are built of hard materials like wood studs, headers, roof trusses, floor joists, soft concrete, drywall, and sheetrock, it explains why rats destroy buildings. Furthermore, they also gnaw through electrical wiring, posing a fire hazard.

Safety Tips for Handling Rodents

  • Always wear protective gear such as masks, gloves, and boots when handling rodents or their urine or droppings.
    * Masks protect against dust but do not protect against viruses.
  • Have damaged and contaminated insulation professionally removed and replaced.
  • Do not vacuum or sweep around contaminated areas as it can stir up dust that may contain contaminants.
  • Spray and wet down dead rodents, nests, droppings, urine, and other contaminated materials with a 10% bleach solution (1 part bleach to 9 parts water) or other disinfectant product and let this soak for 10 minutes or as instructed on the label.
  • Double bag contaminated materials for disposal.
  • Wash hands with soap and water after handling any infested materials.

Why is it So Hard to Get Rid of Norway Rats?

There are many reasons why it is difficult to get rid of rats. One reason is that they breed more prolifically than common rat control measures can keep up with.

For example, female rats reach sexual maturity at 2-5 months and can have three to 12 litters per year with each litter having 4-22 young.

Consequently, DIY solutions are largely ineffective, because they do not address the root of the infestation. Additionally, they pose a safety risk to users.
