Most Common Rodents in Houston

Norway Rats

The Norway rat, also known as the brown rat, is a common inhabitant of Houston. These giant rats measure up to 10 inches long and add another 8 inches with their tails. This species exhibits coarse brown or gray fur and has a blunt nose. Norway rats strongly prefer burrowing and are found in basements, crawl spaces, and building foundations. They are nocturnal and prefer unsanitary conditions.

Roof Rats

Roof and black rats are the other most common rodents in Houston. They have a thin body, large ears, and long tails. In color, they are either black or dark brown, and this discrimination itself is a mark of difference from the Norway rats. Roof rats love high places and are often found in attics, trees, and upper parts of buildings. They have an agile climbing lifestyle and are more common in the coastal and warmer regions, making Houston an ideal habitat.

House Mice

House mice are small rodents commonly found in homes and businesses in Houston. They have a small body, about 2-4 inches long, large ears, small eyes, and a pointed nose. The fur is either light brown or gray. Along with rapid reproduction, these beings have the danger factor of making infestations hard to handle.


Houston is also typical for gray squirrels and bushy-tailed fox squirrels. The fur color varies from gray to reddish-brown. They usually inhabit attics, chimneys, and wall voids, constructing their nests from insulation and other materials.

What Are the Signs of a Rodent Infestation?

The most common signs you have a rodent infestation include: 

  • Droppings: These are generally sighted near the food sources, drawers, under sinks, along the baseboards, and close to hidden areas. Droppings are small, dark, pellet-shaped.
  • Gnaw Marks: Rodents have ever-growing teeth and continually need to gnaw. Look for gnawing marks on furniture, walls, food containers, or wiring materials. 
  • Nests: Rodents build their nests in secret places of shredded paper, fabric, insulation, and other soft materials. The familiar areas are attics, basements, and wall voids.

Rodent Prevention Tips for Homeowners

The best approach is to prevent rodents from entering your house. 

  • Sealing Entry Points: Block all their way through, such as the holes, cracks, or gaps in the walls, doors, and whatnot. 
  • Proper Food Storage: Maintain food in covered containers and immediately clean up spills.
  • Regular Cleaning: Keep the whole house clean and free from clutter to reduce the places where rodents can hide.
