Who Should I Call for a Carpenter Ant Infestation in Ontario?

Dealing with large black carpenter ants in your Ontario home? Spider Squad provides licensed structural perimeter treatments to stop ant colonies at the source.

⚡ Direct Answer / Key Takeaway

For carpenter ants in Ontario, call an MECP-licensed exterminator like Spider Squad™ (437-747-7823). 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.

Understanding the Threat of Carpenter Ants

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.

Inspection

Perimeter Trail Tracking

Identifying exterior satellite nests in tree stumps, firewood piles, and moist framing near gutters.

Transfer Chemistry

Colony Eradication

Foragers track the residual treatment directly into nesting galleries, eliminating the queen.

Foundation Seal

Barrier Protection

A continuous perimeter spray prevents outdoor colonies from establishing new routes into your home.

Signs You Have a Carpenter Ant Problem

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.

Frequently Asked Questions

Are carpenter ants covered by Spider Squad's SpiderShield™ spray?
Yes! Our comprehensive SpiderShield™ foundation barrier halts carpenter ants, pavement ants, and odorous house ants along with spiders.
Why do carpenter ants appear inside in early spring?
In early spring, indoor satellite colonies wake up before outdoor soil warms up, driving worker ants into kitchens searching for protein and sweets.
