Common Rodents to Look Out for This Fall

November 21, 2023

Mouse,Risk.As the weather starts to cool down and the leaves begin to change, many of us look forward to the cozy comforts of fall. However, it’s important to remember that rodents are also preparing for the upcoming winter season. Just like us, they seek warmth and shelter, and our homes can provide the perfect refuge for them. In this blog post, we will discuss some of the most common rodents to look out for this fall and what you can do to prevent them from invading your home.

1. House Mice

House mice are undoubtedly one of the most common rodents found in homes around the world, and they are particularly active during the fall season. These small pests can squeeze through even the tiniest cracks and gaps in your home’s foundation, doors, and windows. Once inside, they can reproduce rapidly and cause extensive damage to your property. To prevent a mouse infestation, it’s important to seal any openings and keep your home clean and clutter-free.

2. Norway Rats

Norway rats, also known as brown rats, are another rodent species that tend to become active in the fall. These rats are larger than house mice and can cause significant damage to both your property and your peace of mind. They are known to burrow underground and can enter your home through sewer lines, utility pipes, or open doors. To keep Norway rats out, make sure your home is well-sealed, especially at the ground level, and keep your outdoor areas clean and free of debris.

3. Roof Rats

Roof rats, also called black rats, are excellent climbers and are most commonly found in attics, ceilings, and upper levels of homes. These rodents are highly adaptable and can squeeze through small openings, making it easy for them to access your home. Roof rats are known carriers of diseases, and their droppings can contaminate surfaces and food. To prevent a roof rat infestation, trim any overhanging trees or branches near your home, seal any holes or openings in your roof, and keep your attic well-ventilated.

4. Squirrels

In the fall, squirrels are busy collecting and storing food for the winter months. While they may seem harmless, squirrels can cause significant damage to your property by chewing through electrical wires, insulation, and even wooden structures. They can enter your home through openings in the roof or eaves, and once inside, they can create nests and breed. To deter squirrels, make sure all openings to your home are sealed, and consider installing metal barriers or wire mesh around potential entry points, such as chimney tops and vents.

5. Chipmunks

Chipmunks, with their adorable appearance, may seem harmless, but they can cause trouble around your property. These small rodents are known for digging burrows and can damage your lawn, garden, and foundation. They can also enter your home through gaps and cracks in your walls, foundation, or vents. To keep chipmunks at bay, fill any holes or openings around your home, and remove any debris or food sources that might attract them.


Fall is the season when rodents like mice, rats, squirrels, and chipmunks start to seek shelter and warmth in our homes. Preventing these unwanted visitors requires vigilance and proactive measures. By sealing up any potential entry points, keeping your home clean and clutter-free, and removing food and water sources, you can significantly reduce the risk of a rodent infestation. Remember, if you do suspect a problem, it’s crucial to seek professional pest control services to effectively and safely remove these pests from your home.
