Carpenter ant control Surrey BC is one of our most requested services every spring and summer. Carpenter ants are one of the most destructive pests in Surrey homes — they excavate wood silently inside walls, roof voids, and structural timbers, often for months before any signs appear. This guide covers everything Surrey homeowners need to know about carpenter ant control Surrey BC.
Signs You Need Carpenter Ant Control Surrey BC
Knowing the signs of carpenter ant activity early is the key to minimising damage. Here’s what to look for before calling for carpenter ant control Surrey BC:
- Frass — Fine, sawdust-like material near baseboards, window frames, or in crawl spaces. Unlike termite frass, carpenter ant frass contains insect parts and looks like pencil shavings.
- Large black ants indoors at night — Carpenter ants are 6–12mm, usually black or dark brown, and most active after dusk
- Rustling sounds in walls — A faint crackling or crinkling sound inside wall cavities at night
- Winged ants (swarmers) indoors in spring — The clearest sign of a mature, established nest inside your Surrey home
- Soft or hollow-sounding wood — Tap window frames, door frames, and fascia boards near moisture-affected areas
Why Carpenter Ant Control Surrey BC Is Urgent
Carpenter ant colonies grow over time. A parent colony establishes satellite nests throughout the structure as the population expands. A mature carpenter ant colony can contain 2,000–3,000 workers causing ongoing structural damage. The longer carpenter ant control Surrey BC is delayed, the more extensive and expensive the damage becomes. Surrey’s wet climate also means moisture-damaged wood — the primary nest site — is common in older homes throughout Newton, Cloverdale, and Fleetwood.
