Carpenter ant and frass pile at a baseboard gallery

Signs You Need to Call an Exterminator for Ants

A few ants on the counter is annoying. Sawdust under the baseboards is a structural emergency.

Quick Answer

If you are consistently seeing large, black ants (Carpenter Ants) indoors, finding piles of fine sawdust (frass) near window sills, or hearing faint rustling sounds in your walls at night, you need a professional immediately. Over-the-counter baits rarely kill the main carpenter ant nest.

The Ankora Advantage

  • Non-Repellent Sprays

    We use specialized sprays that ants can't detect, allowing them to carry the product back to the queen.

The Rotted Deck Ledger

A client in Lakeville noticed a few large black ants on their deck. By the time they called us a year later, the ants had completely hollowed out the deck's ledger board, requiring $3,000 in carpentry repairs before we could even begin treatment.
