Carpenter ant control: locate the nest, fix the moisture

Large black ants indoors, especially at night, often mean a colony in wet wood nearby. Treatment works best when the moisture is fixed too.

Seeing big black ants in wood? A carpenter ant exterminator starts by finding the damp wood the colony lives in.

Call if you notice:

  • Large black ants indoors at night
  • Small piles of sawdust-like debris under wood

What carpenter ants tell you about your house

Carpenter ants don’t eat wood. They excavate galleries in wood that is already softened by moisture, then push out coarse "frass." Atlanta’s mature trees, frequent summer storms and older wood trim make roof eaves, window sills, porch columns and bathroom walls common spots. If you’re unsure whether you have ants or termites, see carpenter ant vs. termite.

Signs of carpenter ants

  • Large ants indoors at night

    Often seen in kitchens and bathrooms in spring.

  • Frass piles

    Sawdust-like shavings with insect parts below a gap or crack.

  • Winged reproductives

    Indoor swarmers mean a mature colony.

  • Rustling in walls

    Sometimes audible near nest galleries.

Treatment approach

  1. Inspection

    Trace foraging trails at dusk, find moisture-damaged wood, and check trees and stumps touching the structure.

  2. Colony treatment

    Targeted baits and labeled void treatments at nest sites.

  3. Moisture correction

    Repair leaks, flashing, gutters and rotted trim. Without this, colonies tend to return.

How it works

  1. Call

    Tell us what you’re seeing, where, and for how long. Photos help.

  2. Inspection

    A technician checks the house, crawl space or basement, attic access and yard, and finds the source, not just the symptoms.

  3. Your plan

    You get the treatment options that fit your home, what each involves, and the factors that set the cost, before any work starts.

  4. Treatment & follow-up

    Targeted treatment, practical fixes you can make, and follow-up visits where the pest needs them.

Frequently asked questions

Are carpenter ants as bad as termites?

They usually cause slower damage than termites, but they signal moisture problems that can also damage wood.

Do carpenter ants mean I have rotten wood?

Often, yes. They prefer wood softened by moisture, so look for roof leaks, damp window sills, gutters overflowing onto trim, and plumbing leaks near where you see them.

Can I just spray the ants I see?

Spraying foragers rarely reaches the colony, and carpenter ants often have satellite nests in walls. Baits and treating the nest sites, plus fixing the moisture, give longer-lasting results.
