How to Get Rid of Disease Spreading Norway Rats & Rodent Burrows in Larkspur, CA

Norway rats are also known as brown rats, sewer rats and wharf rats. Even though they are called Norway rats, they aren’t from Norway. They are native to Asia and arrived in England via Norwegian ships before they made their way to the United States. These are the rats that populate most American cities.

Norway Rat Appearance & Behavior

Norway rats are large rodents that have small eyes, ears and short tails. They have furry brown and gray bodies with ears and tails that are absent of hair. Their tails are shorter than their head and body. Norway rats can be 10 to 2 inches long, including their tail. As fall approaches, and food and water become scarce, they will enter your home. They can get their bodies through an opening the size of a quarter. They like to live in burrows and will often dig holes that surround your home. You may notice grease stains along walls and chew marks on wires and food items. Their droppings are capsule-shaped and will be found along the paths they travel.

Norway Rat Damage & Diseases

Norway rats are primarily nocturnal. If you see one during the day, you have a problem. They breed very quickly! They reach reproductive maturity at 3 months of age. Females go into heat every 4 or 5 days and can mate just a day or two after they’ve given birth. They will breed all year long but fall and spring are peak times for breeding. The average female rat can have 4 to 6 litters each year with 8-12 pups per litter. These numbers make it clear to see how dangerous a rat infestation can become inside your home. Norway rats can carry disease and chew through wiring that can cause electrical fires. They can also contaminate food because they can bring fleas into the home.

Norway Rat Prevention

Norway rats need food, water and shelter. The best way to get rid of them is to cut off their food supply. This can seem like a difficult task considering they eat anything and everything. Even your garbage isn’t safe; they actually love it! They will chew though almost anything, so use metal trash cans instead of plastic ones. Inside your home, seal all food in glass or metal containers. They are also attracted to pet food, so try not to keep it out and make sure it’s sealed in a metal bin. You should also remove piles of wood and debris they will use for shelter. If you do have firewood, stack it away from your home. Norway rats are good climbers so make sure tree limbs that might give them access to your home are trimmed. Seal any opening you find that are larger than ¼ inch. Make sure you take care of any moisture issues in the home that might attract them.
