Carpenter Ants


Carpenter Ants, the name brings to mind images of little builders; however, these ants might more appropriately be named demolition ants because they burrow into already damaged or aging wood and cause it to deteriorate faster. In nature, Carpenter Ants are invaluable as they expedite the decomposition process of dead trees; however, they cannot differentiate between a dead tree and the wood in our homes making our houses attractive nesting sites. In addition to their destructive habits, they are also very intrusive as they forage throughout our homes looking for sugars and fats.

Prevention Tips

    • Keep firewood and scrap wood piles at least 100 feet away from structures and off the ground if possible
    • Fix any damaged or rotting wood on the structure as this is a likely entry point for Carpenter Ants
    • Repair any moisture problems such as roof or plumbing leaks
    • Trim back tree branches and foliage at least 3 feet away from structures to eliminate access for pests
    • Seal cracks and spaces in the foundation and around plumbing and electrical fixtures entering the house
    • Remove any tree stumps close to the house as they provide a great nesting location for Carpenter Ants


Carpenter Ants are the largest ant species, but size is not always the most accurate way of identifying them because workers can be various sizes (1/4 inch to 1/2 inch). Often times in the Seattle area, the Carpenter Ants are black with red legs and a smooth back, but can also have brown, orange or yellow leg colorations. Often times, home owners see winged reproductive ants when they leave the nest and swarm in the spring. In addition to sightings of ants, homeowners may also notice sawdust (frass) from the ants burrowing into the wood and a rustling sound from inside the walls much like walking through dried leaves. When you call Eagle Pest Eliminators, we positively identify the ant species and provide recommendations to ensure effective and safe treatments, and your 100% satisfaction.
