Rodents in Winter: A Complete Guide to Detecting and Controlling Them

Reading time: 3 minutes

Winter is a key time to understand and manage rodent infestations. Here is a detailed and informative article that explores winter rodent behavior and offers tips for effectively detecting and controlling them.

Increase in Rodents in Winter

Contrary to popular belief, most rodents do not hibernate in winter. Species like mice and rats remain active, seeking shelter in homes to protect themselves from the cold and find food. In fact, winter can see a significant increase in rodent infestations in homes, as they seek to stay warm and feed.

Rodent Behavior in Winter

Rodents, such as mice and rats, adopt very specific strategies to survive during the cold months:

Food Storage:

They begin hoarding food as early as fall, foraging for foods like grains, birdseed, compost scraps, and even paper. These reserves help them survive during months when food is scarce.


Rodents build nests from a variety of materials, often in warm, isolated corners of homes. House mice seek out artificial structures for their nests, while field mice may use abandoned bird or squirrel nests. Either way, these two types of mice often gather together to keep warm during cold spells.

Rodent Entrance:

Mice can enter through openings as small as a dime, while an opening the size of a quarter is sufficient for a rat. These small passages, located under doors, in ventilation openings, or around cables and pipes, facilitate the entry of rodents.

How to detect a rodent infestation

To find out if you have rodents in your home in winter, you can look for the following signs:

- Noise: Scratching or chewing noises, especially at night.

- Material Damage: Bite marks on electrical cables, furniture, or packaging containing food.

- Excrement: These are characterized by small, black, pointed droppings.

- Odor: An odor of ammonia coming from rodent urine may be felt in your environment.

- Nests: Accumulations of materials such as paper or fabric in isolated areas of the house.

- Behavior of your pets: Dogs and cats can be disturbed by the presence of rodents, paying attention to unusual places in the house. A change in behavior in your pets can therefore be a sign of the presence of rodents in your home.

- Tracks and Tails: Small prints or trailed tail lines will appear in dusty areas

Prevention and Control

To prevent rodent infestations:

- Seal openings: Close and seal all openings through which rodents could enter. Effective products exist for this purpose such as anti-rodent copper net . It is important to know that mice can enter through holes the size of a pencil.

- Safe food storage: Store food in airtight containers.

- Cleaning: A clean and tidy house is less attractive to rodents. Regularly eliminating potential food sources and standing water is crucial to discouraging rodents from taking up residence

- Regular Inspection: Thanks to prevention traps , you can regularly check them to prevent rodents from entering your home and to determine if there have been any attempts.

Conclusion :

Understanding rodent behavior in winter and recognizing the signs of infestation is essential for effective management of these pests which can cause a lot of damage. With a proactive approach and, if necessary, the help of certain products, you can protect your home from these unwanted guests during the cold months.
