In this article, we will explore the best times to seek the expertise of an ant exterminator scarborough and provide valuable insights into keeping your home ant-free.

Seasonal Patterns of Ant Activity

Ant activity levels vary throughout the year, and understanding these patterns is crucial for knowing when to be proactive about ant control.


Spring is a time of rejuvenation for many insects, including ants. As the weather warms up, ant colonies become more active, with worker ants bustling about. They emerge from their winter dormancy, seeking food sources and expanding their nests. During this time, it’s common to see foraging ants exploring indoor and outdoor spaces. Homeowners may notice ants scouting for crumbs and sweets in kitchens and gardens, making spring the ideal season for preventive measures.


Summer marks the peak season for ant infestations. The combination of warm temperatures and abundant food sources creates the perfect environment for ants to thrive. Ant colonies reach their maximum activity levels, and infestations become more pronounced. Observing a surge in ant activity within your home during the summer months indicates that action is needed. Addressing ant infestations promptly during this season is crucial to prevent their population from spiralling out of control.


As temperatures cool in the fall, ants begin preparing for the impending winter months. This transition prompts some ant species to enter homes for warmth and shelter. These intrusions can lead to indoor infestations if not addressed promptly. Fall is a critical time to take action against ant infestations, as it helps prevent them from overwintering within your property. Addressing the issue in the fall can minimize the chances of a resurgence in the following spring.


While ant activity slows significantly during the winter, it’s important to note that it doesn’t come to a complete halt. Some ant species, such as pharaoh ants, remain active indoors, especially in heated buildings. Winter can be an ideal time to lay the groundwork for preventing future ant infestations. 

Conducting a thorough home inspection and sealing potential entry points can help ensure you’re caught on time when spring arrives. Being proactive in the winter can minimize the risk of a full-blown infestation once the weather warms up again.

Vacuum floors to pick up crumbs and food particles. Additionally, be mindful of emptying trash cans regularly, as the odours from discarded food can attract ants.

Trim Vegetation and Branches

Ants often use branches and overgrown vegetation as bridges to access your home. Trim trees, bushes, and shrubs that touch or overhang your house. Creating a gap between your home and outdoor vegetation reduces the likelihood of ants finding their way inside. This simple landscaping measure can act as a natural deterrent against ant infestations.

Regularly Inspect and Clean Outdoor Trash Bins

Regularly inspect and clean your outdoor trash bins to remove any residues that might entice ants. Consider using trash bin liners and securing the lids tightly to minimize odours and prevent ants from accessing the contents.
