They can damage property, contaminate food, and spread diseases. While rodents can be an issue all year round, there is a specific time of the year known as “rodent season” when their activity tends to increase. In this blog post, we will explore what rodent season is, why it happens, and how long it typically lasts.

1. What is Rodent Season?

Rodent season refers to the time of the year when rodent activity becomes more prevalent. It is usually during the colder months, specifically in the fall and winter. During this time, rodents seek shelter, food, and warmth, leading them to invade buildings and homes. This increased activity can be attributed to a few factors, including the natural behavior of rodents and the changes in their environment.

2. Natural Behavior of Rodents

Rodents, such as mice and rats, are known for their ability to reproduce quickly and adapt to various environments. They are opportunistic creatures that are constantly searching for sources of food and shelter. In the wild, rodents would typically find ample food sources during the warmer months. However, as the temperature drops and the availability of food decreases, they become more desperate and more inclined to invade human spaces.

3. Changes in their Environment

The changing seasons bring about changes in the environment that can contribute to an increase in rodent activity. As the weather gets colder, rodents sense the drop in temperature and the potential scarcity of food. They instinctively seek out warm and sheltered areas for survival. Buildings, homes, and even vehicles provide ideal places for them to seek refuge. Additionally, the fall season is when crops are harvested, leading to an abundance of food sources. This attracts rodents to areas where food is plentiful, including residential and commercial properties.

4. How Long Does Rodent Season Last?

The duration of rodent season can vary depending on several factors, including geographical location and weather patterns. In general, rodent season tends to last throughout the fall and winter months. It typically starts in late summer or early fall when temperatures begin to drop. This is when rodents start looking for warmer places to nest and food sources to sustain themselves during the colder months. Rodent season persists until the arrival of spring when the temperatures rise again and natural food sources become more abundant.

However, it’s important to note that while rodent activity may peak during the fall and winter, rodents can still be a concern during other times of the year. In warmer climates or areas where food is readily available year-round, rodents may not experience a significant decrease in activity during the summer months.

5. Preventing and Managing Rodent Infestations

As rodent season approaches, it is crucial to take proactive measures to prevent and manage infestations. Here are some steps you can take:

– Seal any cracks or holes in your building’s exterior to prevent rodents from entering.

– Store food in airtight containers and keep your premises clean and free of crumbs or food debris.

– Keep garbage tightly sealed and dispose of it regularly.

– Trim shrubs and trees near your property to eliminate potential entry points.

– Remove clutter and stored items that can provide hiding spots for rodents.

– Consider implementing pest control measures such as traps or bait stations, or consult with a professional pest control service for more comprehensive solutions.

By taking these preventive measures, you can reduce the likelihood of a rodent infestation and protect your property from the damages and health risks associated with these unwanted visitors.


Rodent season refers to the time of the year when rodent activity increases, typically during the fall and winter months. This can be attributed to the natural behavior of rodents and the changes in their environment. While rodent season may vary in duration, it generally persists throughout the fall and winter until the arrival of spring. By being proactive in preventing and managing rodent infestations, you can safeguard your property from the damages and risks associated with these pesky creatures all year round.
