Carpenter ants are one of Southern Ontario’s most destructive structural pests. They don’t eat wood—they excavate it to build galleries, weakening your home over time.
Early warning signs include:
- Large black ants appearing indoors, especially at night
- Sawdust-like debris (frass)
- Rustling sounds inside walls
- Ant trails along foundations or decks
Carpenter ant colonies can grow to tens of thousands, making early detection critical. Professional treatment targets both parent and satellite colonies for full elimination.
