    Do You Have Carpenter Ants?

    Carpenter ants do not eat wood. They hollow it out to nest, usually where wood is damp, and the damage builds every season they stay.

    Large Black Ants

    Big black ants indoors, much larger than the small ants that trail to food. Seeing them in winter often means a nest inside.

    Sawdust and Galleries

    Piles of coarse sawdust, called frass, below trim, windows or beams, and smooth tunnels inside damaged wood.

    Ants Coming From Outside

    Trails from trees, stumps and woodpiles to the house, often at night along the foundation or utility lines.

    Other signs: winged ants indoors in spring, faint rustling inside walls, and wood that sounds hollow near leaks. How to tell whether carpenter ants are damaging your home.

    How It Works

    From Finding the Nest to a 90 Day Warranty

    Locally owned and family operated since 1987. Call before noon, Monday through Friday, for same day service.

    1. Inspection. We trace trails and look for frass and damp wood to find where the colony is nesting, inside or out.
    2. Treatment. Treatment is aimed at the nest and the paths the ants use, not just the ants you can see.
    3. Ongoing service. Choose year round or quarterly service to keep carpenter ants from coming back.
    4. 90 day warranty. Carpenter ant service is backed by a 90 day warranty.

    How We Treat Carpenter Ants

    The goal is the nest. Killing the ants you can see does little if the colony is still in the wall.

    Inspection and Treatment

    A carpenter ant inspection follows the ants back to where they nest, then treatment goes where the colony lives and travels. Carpenter ants vs termites.

    Carpenter Ant Questions

    Carpenter ants are large black ants, much bigger than the small ants that trail to crumbs. Other signs are piles of coarse sawdust below trim, windows or beams, and winged ants indoors in spring. If you see big black ants inside during the winter, the nest is likely inside the house.

    Carpenter ants do not eat wood the way termites do. They hollow it out to make room for the nest, usually where the wood is damp, and the damage grows as the nest expands. Because they leave the nest to look for food, they are usually easier to spot than termites, so call as soon as you see them. Here is more on carpenter ants vs termites.

    Usually not. Bait traps can lure more carpenter ants to the area and only deal with a few adults, while the colony keeps producing new ants. Nests inside walls, floors, sheds and trees can quiet down in the winter and come right back in the summer, which is why treatment needs to reach the colony.

    We start with an inspection to find where the colony is nesting, then treat the nest areas and the paths the ants use. Year round or quarterly service keeps them from coming back, and carpenter ant service is backed by a 90 day warranty. Call 412-822-7610 to schedule your carpenter ant inspection.
