If you’ve noticed more "uninvited guests" in your home this month, you aren’t alone. Between a wet spring in Southwestern Ontario and a rapid thaw in the North, London and Thunder Bay are seeing a massive surge in pest activity.

At Toodaloo Pest Control, we aren't just about "spraying and praying." We use tech-forward solutions to find out exactly where pests are hiding. Here is what you need to know to protect your home this season.

What are the most common pests in Ontario right now?

The Direct Answer: In May 2026, London residents are seeing a spike in Silverfish and Pavement Ants due to high humidity. Meanwhile, Thunder Bay is experiencing a surge in Carpenter Ants and Rodents as they migrate into structures following the spring thaw. Identifying "frass" (sawdust) or discarded wings near windowsills is the first sign of an active infestation.

Local Spotlight: London vs. Thunder Bay

While both cities are in Ontario, their "pest profiles" this week look very different:

London: The Humidity Challenge

Southwestern Ontario's humidity is a playground for Silverfish. These nocturnal pests love damp basements and crawlspaces. Because they can live for years and eat through book glue, wallpaper, and clothing, early detection is key.

Thunder Bay: The Structural Threat

In the North, Carpenter Ants are the primary concern. Unlike termites, they don't eat wood; they carve galleries into your home's framing to build nests. If you see large black ants inside during a rainstorm, there is likely a colony already established in your walls.

3 Steps to Protect Your Home This Weekend

Dehumidify the "Dark Zones" (London Focus): Keep your basement humidity below 50%. This naturally "dries out" Silverfish and makes your home uninhabitable for them.
The "Quarter Test" (Thunder Bay Focus): A rat can fit through a hole the size of a quarter. Walk your perimeter and seal any gaps in your siding or foundation with steel wool.
Trim the "Pest Bridges": Ensure tree branches and shrubs are trimmed at least 2 feet away from your roof and walls. This prevents ants and squirrels from using your trees as a highway onto your house.
