Carpenter Ants: The Silent Structural Threat of Summer

Carpenter Ants: The Silent Structural Threat of Summer

Carpenter ants are among the most destructive summer pests in the Fraser Valley. Unlike typical nuisance ants, they excavate wood to create nesting galleries.

Left untreated, damage can become extensive over time.

Why Summer Is Peak Carpenter Ant Season

Warm weather triggers:

  • Increased foraging activity
  • Expansion of satellite colonies
  • Swarming events

Moisture-damaged wood is particularly attractive to nesting carpenter ants.

Where They Commonly Nest

Inspections often uncover carpenter ant activity in:

  • Deck posts
  • Window frames with water damage
  • Roofline trim
  • Bathroom wall voids
  • Garages and sheds

Because colonies often exist in multiple locations, simply treating visible ants is rarely sufficient.

Warning Signs of Carpenter Ant Activity

  • Large black ants indoors
  • Fine sawdust-like debris (frass)
  • Rustling sounds in walls
  • Winged ants during mating season

Early detection can prevent expensive structural repairs.

Why Comprehensive Treatment Matters

Professional carpenter ant control focuses on:

  • Locating parent and satellite nests
  • Treating structural voids
  • Addressing moisture issues
  • Preventing future nesting
