Rodents, including rats and mice, can cause damage to homes and pose a threat to human health. It is important to recognize the signs of a rodent infestation early on to prevent further damage and ensure the safety of your family. In this article, we will discuss the various signs of rodent infestation and what steps you can take to get rid of them.

Rodent Infestation Signs

What are rodents?

Before we delve into the signs of rodent infestation, let's briefly discuss what rodents are. Rodents are a group of mammals that are characterized by their continuously growing incisors. There are many species of rodents, including rats, mice, squirrels, and chipmunks. Rodents are found all over the world and are known for their ability to adapt to different environments.

Signs of rodent infestation


Rodent droppings are a clear sign of a rodent infestation. They are typically small, dark, and pellet-shaped. You may find them in areas where rodents are likely to feed or travel, such as near food storage areas or along walls.

Gnaw marks

Rodents have a constant need to gnaw on objects to keep their teeth sharp and healthy. As a result, you may notice gnaw marks on wires, furniture, or walls. If you find small holes in food packaging, this is also a sign of rodent gnawing.


Rodents often build nests in areas that are hidden from view, such as inside walls, attics, or crawl spaces. If you find shredded paper, fabric, or other materials in these areas, this is a sign of a rodent nest.

Unusual noises

If you hear scratching, scurrying, or squeaking noises in your walls or ceiling, this is a sign of a rodent infestation. These noises are often more noticeable at night when rodents are most active.

Grease marks

Rodents leave grease marks on surfaces that they frequently travel across. These marks are often found along walls or near food sources.


Rodent footprints are another sign of an infestation. You may notice small footprints in areas where rodents are likely to travel, such as along walls or near food sources.

Foul odor

Rodents have a distinct smell that is often described as musty or urine-like. If you notice an unusual odor in your home, this may be a sign of a rodent infestation.


Finally, the most obvious sign of a rodent infestation is actually seeing a live or dead rodent in your home. If you spot a rodent, it is important to take action immediately to prevent further infestation.

Getting rid of rodents

If you suspect that you have a rodent infestation, there are several steps you can take to get rid of them:

Seal entry points

Rodents can enter your home through small holes or cracks. Seal these entry points with caulk or steel wool to prevent further infestation.

Remove food sources

Rodents are attracted to food sources, so it is important to keep your home clean and free of crumbs and spills. Store food in sealed containers and clean up spills immediately.

Set traps

Traps can be an effective way to get rid of rodents. Place traps in areas where you have noticed signs of infestation, such as near droppings or gnaw marks.

Call a Professional

If you are unable to get rid of the rodents on your own, consider calling a pest control professional. They can provide more effective and long-lasting solutions to your rodent problem.

Here are some types of professionals who can help with rodent infestations

Pest control companies

These companies specialize in treating and preventing pest infestations, including rodents. They can provide a range of services, such as inspection, trapping, and baiting, to help eliminate the infestation.


Similar to pest control companies, exterminators are trained to identify and treat pest infestations, including rodents. They may use chemicals or other methods to eliminate the infestation.

Wildlife removal specialists

If the rodents you're dealing with are wild animals, such as rats or squirrels, a wildlife removal specialist can help. These professionals are trained to safely capture and relocate wild animals.

Building maintenance professionals

In some cases, rodent infestation may be caused by structural issues in a building, such as gaps or cracks that allow rodents to enter. Building maintenance professionals can help identify and address these issues to prevent future infestations.

When choosing a professional to help with a rodent infestation, be sure to do your research and choose a reputable and experienced provider. You can check reviews and ratings online, and ask for references from friends or neighbors who have dealt with similar issues.
