During the colder months of the year, many rodents look for warmth and shelter inside their homes. While a larger infestation will be obvious, smaller ones may go unnoticed for a while

Even though it can be hard to tell if you are dealing with a rodent infestation, there are some tell-tale signs of a problem. Keep reading to learn about the signs. You need to contact a professional exterminator for help with a rodent problem. 

Chew Marks

Discovering smaller chew marks on cardboard, wood, or other materials is a tell-tale sign of a rodent problem. Rodents of all sizes can gnaw through almost everything. If you notice these signs on wires or baseboards, it’s a good idea to call for an exterminator right away. 

Musky Smell

Most rodent infestations will create a musky odor. The smell will typically grow stronger as the problem gets worse. 

Rotting Smell

When a rodent dies inside your home, the smell is going to be apparent. It’s a good idea to call a professional to find and remove any dead rodents in your home, along with other pests. This can be a hazardous process, which is why it is best to leave it to the pros. If you decide to remove dead rodents alone, be sure you use gloves and wear a mask to prevent any issues. 

Pets Acting Strangely

Has your cat or dog started to scratch at the walls? Do they seem erratic in certain parts of the home? If so, it may be a sign of a rodent problem. Be sure to note where your pets are showing this behavior and give it to the exterminator you hire. 


Rodent droppings are some of the most easily seen signs of a problem. Usually, the droppings will be small, dark brown, and have a pointed end if you have mice. Rat droppings are larger and may vary in shape or size based on the type of rat present. When cleaning up droppings, be sure to wear gloves and a mask to protect yourself from any potential hazards. 


Have you noticed tiny rodent footprints around your house? If so, it’s another sign of an infestation. You should look for these footprints up in higher areas where dust collects. 


Rats and mice may gnaw smaller holes in thinner materials or walls to create a new entry point. This is going to let them have easier access to your home in the future. 


It’s often difficult to figure out the cause of allergies, but allergies caused by pests are sometimes overlooked. The droppings and fur from rodents can result in allergic reactions in many people. 

If you believe you have a rodent problem, there are more than a few things to consider. However, it is a good idea to call professionals for help. Doing this will ensure that your pest problem is handed, and the professional can give you tips and resources to ensure the pests don’t come back.
