Each winter in the United States, 21 million homes are infested by rodents. Mice, rats, and even squirrels commonly invade Worcester homes and businesses. Rodents aren’t just a nuisance; they are also dangerous and destructive.

Rodents have lived among humans throughout history, relying on us for water, food, and shelter. They can easily gain access to structures through small holes and gaps—rats only need openings the size of a quarter, while mice can squeeze through holes as small as a dime. Once inside, they quickly breed and multiply, which makes controlling them a challenge for property owners.

In this post, we’ll investigate which rodents pose the biggest threats to Worcester homes and businesses, the dangers they present, and how to prevent and control them.

The Most Common Rodents In Worcester

House Mice

House mice are the most prevalent of the commensal rodents. They are usually gray with cream-colored undersides, with pointed muzzles and large ears. Their bodies are between 2½ - 3¾ inches long, and their tails are generally 2¾ to 4 inches in length. House mice breed rapidly. A female can produce six babies every three weeks and up to 35 offspring per year.

Norway Rats

Norway rats, also known as street rats or sewer rats, arrived in the United States in the 1700s on ships from Europe. They are 7-9½ inches long, with blunt muzzles and small eyes and ears. They are typically brown with some black hairs interspersed, with gray or white bellies. Norway rats are notorious for their ability to chew through just about anything, leading to severe property damage.

Roof Rats

Roof rats, also known as black rats or ship rats, are often found living in the attics or rafters of buildings. Their bodies are about 6-8 inches in length, and they have long, scaly tails. They are brown with some black and have gray, white, or black undersides. Like other rodents, roof rats damage property and are vectors for disease.


While less likely to enter homes and businesses than rats or mice, squirrels will sometimes come indoors seeking food or shelter. Squirrels are typically gray with some white and brown and are known for their bushy tails and climbing abilities. They are not known to spread disease, but they can inflict both interior and exterior property damage.

The Dangers Of Rodents In Worcester

Rodents are a serious threat to homes and businesses in Worcester. Not only do they cause property damage through their incessant gnawing of materials, but mice and rats are also carriers of numerous diseases.

Both Norway and roof rats are known for spreading typhus, jaundice, rat-bite fever, trichinosis, and salmonellosis. House mice are transmitters of leptospirosis, tularemia, salmonellosis, and lymphocytic choriomeningitis (LCM.) Both rats and mice also contaminate food and cooking surfaces. Rodents may also trigger allergic reactions and bring other pests onto your property, such as fleas and ticks.
