Norwegian rats, also known as brown rats, are a common pest in San Diego. These rodents are known for their destructive behavior, as they can cause damage to buildings, contaminate food, and spread disease.

Norwegian rats are larger than the more common black or roof rats and can grow up to 18 inches long, including their tail. They have stocky, brownish-gray bodies and scaly tails that are shorter than their bodies. They are primarily active at night and are excellent climbers and swimmers.

One of the main reasons for the presence of Norwegian rats in San Diego is the availability of food, shelter, and warm weather. These rats can thrive in a variety of environments and can survive on a wide range of food sources. They are known to scavenge in garbage cans, compost piles, and gardens. They can also enter homes and buildings through small openings in search of food, water, and shelter.

Norwegian rats are big. Because of their size, they can cause significant damage to buildings and infrastructure, as they will gnaw on electrical wires, pipes, and wood structures. They can grow to a length of nearly 16 inches! Their front teeth constantly grow, so rats need to constantly chew to keep their teeth from getting too long.

To prevent a rat infestation, it is important to eliminate sources of food and shelter. This can include storing food in sealed containers, keeping trash cans sealed, and removing piles of debris. It’s also important to seal any openings in buildings, such as cracks in walls or foundations, and to eliminate any standing water sources.

If you suspect a rat infestation, it is important to contact a professional rodent pest control company. They will be able to identify the type of rat and determine the best course of action to eliminate the infestation. This may include traps, baits, or exclusion methods.

Regular inspections and maintenance can also help to prevent a rat infestation. This can include regular cleaning and sanitation, as well as monitoring for signs of rat activity, such as droppings, gnaw marks, and burrows. You may also see a grease trail along wood fences, conduit, or even downspouts. These indicate rodent activity as they constantly leave a trail of urine and feces.

Norwegian rats can be a serious problem in San Diego, and it’s important to take preventative measures to avoid an infestation. They can contaminate food and spread diseases such as salmonellosis, hantavirus, and leptospirosis. By eliminating sources of food and shelter, sealing openings in buildings, and contacting Bite Away Termite and Pest Control, Inc. if an infestation is suspected, you can help to protect your San Diego home and community from the destructive and unhealthy impact of these pests.
