Structural Pest Control
Dealing with large black carpenter ants in your Ontario home? Spider Squad provides licensed structural perimeter treatments to stop ant colonies at the source.
For carpenter ants in Ontario, call an MECP-licensed exterminator like Spider Squad™ (905-938-7498). We apply structural perimeter treatments and non-repellent transfer barriers that eliminate satellite nests inside wall cavities and prevent ants from foraging from exterior trees into your foundation.
Carpenter ants are among Ontario's most destructive wood-destroying insects. Unlike termites, they do not eat wood, but hollow out smooth galleries inside structural framing, deck joists, and window headers to house their satellite colonies.
Spraying OTC bug spray only kills visible worker ants and often causes the colony to fracture into multiple nests. Professional non-repellent treatments allow foraging ants to carry active ingredients back to the queen.
Identifying exterior satellite nests in tree stumps, firewood piles, and moist framing near gutters.
Foragers track the residual treatment directly into nesting galleries, eliminating the queen.
A continuous perimeter spray prevents outdoor colonies from establishing new routes into your home.
Key warning signs include finding large black ants (1/2 to 5/8 inch long) in kitchens or bathrooms, discovering small piles of fine sawdust (frass) beneath baseboards, or hearing faint rustling sounds inside drywall voids at night.
