Top 5 Seasonal Pests in Ottawa and How to Prevent Them
As the seasons change, so does the variety of pests that can invade your home in Ottawa. Understanding which pests are most prevalent during each season and how to prevent them can save you time, money, and stress. Here, we explore the top five seasonal pests and provide effective prevention tips.
Spring: Ants
With the thawing of the snow, ants become active and start seeking food sources. They often infiltrate homes through tiny cracks and crevices.
Prevention Tips
To keep ants at bay, seal any entry points and maintain cleanliness in your kitchen. Store food in airtight containers and regularly sweep up crumbs. Consider using natural repellents like vinegar and essential oils.

Summer: Mosquitoes
Ottawa's warm summer months are ideal for mosquitoes, which breed in standing water and can quickly become a nuisance.
Prevention Tips
Eliminate standing water around your property, such as in birdbaths or clogged gutters. Use mosquito nets and consider installing screens on windows and doors. Planting citronella or using citronella candles can also help deter them.

Fall: Spiders
As the temperatures drop, spiders seek warmth and shelter inside homes. While most are harmless, they can still be unsettling.
Prevention Tips
Reduce clutter and regularly vacuum corners and crevices where spiders may hide. Seal cracks and use peppermint oil as a natural repellent. Keeping outdoor lights off can also reduce their attraction.
Winter: Mice
When winter arrives, mice look for warmth and food inside homes. They can cause significant damage and spread diseases.
Prevention Tips
Seal entry points and use steel wool to block any holes. Store food in sturdy containers and maintain cleanliness. Traps and baits can be effective, but consider professional pest control for severe infestations.

Year-Round: Cockroaches
Cockroaches are a persistent problem that can occur at any time of the year. They thrive in warm, humid environments and are often found in kitchens and bathrooms.
Prevention Tips
Keep your home clean and dry. Fix leaks promptly and ventilate damp areas. Use cockroach baits and traps, and regularly inspect under sinks and around pipes.

By understanding the seasonal habits of these pests and taking proactive steps, you can protect your home and enjoy a more comfortable living environment. If infestations persist, it may be time to consult a professional pest control service to address the problem effectively.
