In Bellevue, WA, carpenter ants are a significant pest problem that can cause serious structural damage to homes. Understanding how to prevent infestations is crucial for protecting your property and maintaining a safe living environment. This guide covers effective strategies homeowners can use to keep carpenter ants at bay year-round.

Understanding Carpenter Ant Behavior

Carpenter ants don’t eat wood like termites, but they hollow it out to create nesting galleries. In Bellevue’s moist climate, they are especially attracted to water-damaged wood found in homes, decks, and fences. Common signs of an infestation include sawdust piles (frass), rustling noises in walls, and the presence of large, black or red ants inside or around the home.

Top Strategies to Prevent Carpenter Ant Problems

1. Seal All Entry Points

  • Inspect and seal cracks, crevices, and gaps around doors, windows, siding, and utility pipes.
  • Repair damaged screens and weather stripping to block easy access.

2. Manage Moisture Issues

  • Fix leaks promptly, especially in the roof, basement, and around windows.
  • Use dehumidifiers in damp areas and ensure proper ventilation in crawl spaces and attics.
  • Maintain gutters and downspouts to direct water away from the foundation.

3. Trim Trees and Shrubs

  • Keep vegetation trimmed back at least 2–3 feet from the home’s exterior to prevent easy pathways for ants.
  • Remove dead tree stumps and fallen logs, which serve as prime nesting sites.

4. Store Firewood Properly

  • Stack firewood off the ground and away from the home.
  • Inspect firewood for ants before bringing it indoors.

5. Conduct Regular Inspections

  • Periodically inspect your home for signs of carpenter ants, especially in spring when they become more active.
  • Look for frass, listen for faint rustling noises, and monitor for the appearance of winged ants (swarmers).

What to Do if You Suspect an Infestation

If you notice signs of carpenter ants, it’s essential to act quickly. Contact a local pest management professional who specializes in carpenter ant removal. Professional treatment often includes locating the nest, using targeted insecticides, and providing moisture management recommendations to prevent reinfestation.
