Hosting rodents inside your home can bring a number of unwanted issues.

Because these pests can carry pathogens that can transmit harmful diseases to humans and pets, as outlined by the CDC, a rodent infestation can pose significant health risks - such as leptospirosis, rat-bite fever, and salmonellosis. Not only that, they’re also capable of causing damage to the interior of a home, from chewing through electrical wires, nesting in insulation and contaminating food supplies.

Norway rats can be destructive to the home and the areas around the home. Unlike other rodents, like mice, which rarely grow to be larger than 2 inches in length, Norway rats average about 16 inches in length. Though they prefer to live in outdoor habitats, cold weather may drive these pests indoors in search of warm shelter.

Identifying Norway Rat Damage

A house that is hosting Norway rats may begin to quickly show the warning signs of Norway rat damage. They may dig burrows within flower beds and packed soil located close to a home’s structure, with each burrow entrance spanning between 2 to 4 inches wide. Unfortunately, it only takes approximately three weeks for pregnant rats to give birth to a new litter of babies. With the average litter containing 6 - 10 rat pups, one single rat nest can become a full-blown infestation within a matter of a few weeks.

Standing water outdoors, like in birdbaths and pet water dishes, can also attract these pests.

Keep food supplies secure

Along with heated shelter, Norway rats are drawn to available food sources. Any home that leave s pet food and birdseed outside or in the garage is at risk of a Norway rat infestation. Keep all pet food and birdseed stored in airtight containers, and clean up any loose pieces of food immediately to avoid attracting these pests.
