Signs You Have Carpenter Ants in Your Long Island Home
You have carpenter ants in your Long Island home if you see large black ants indoors year-round, small piles of coarse sawdust-like frass along baseboards or below window frames, or hear a faint rustling inside walls at night. Wooded Suffolk County properties, shoreline homes in Nassau, and any house with a history of gutter overflow or deck flashing issues are the most common calls. Satellite nests often form in door and window frames, dishwasher voids, and around chimney flashing. Winged reproductives appearing indoors in spring are a strong signal that a mature colony is nesting inside the structure, not just visiting from outside.
How Bobby Bugs Treats Carpenter Ants
Bobby Bugs treats carpenter ants on Long Island by locating the parent and satellite nests, injecting non-repellent product directly into affected voids, and treating the exterior perimeter to intercept foraging trails. Expect a free estimate first, then a 6-month written guarantee.
- 1Free on-site inspection: identify affected wood, moisture sources, and likely nest locations.
- 2Written estimate before any work begins.
- 3Direct injection of non-repellent product into wall voids, window frames, and other identified nests.
- 4Non-repellent exterior perimeter treatment to catch outbound and inbound foragers.
- 5Moisture-source flagging so structural or roofing issues can be addressed by a contractor.
- 6Written 6-month guarantee with return visits if activity resumes.
How Long Does It Take to Get Rid of Carpenter Ants?
Most Long Island carpenter ant jobs show a sharp drop in indoor activity inside 2 weeks, with the parent colony collapsing over 4 to 8 weeks as foragers move product back into satellite nests. Mature multi-nest infestations in older wooded Suffolk homes sometimes need a follow-up visit inside the 6-month guarantee window. Moisture repair speeds recovery. Any bounce-back inside the guarantee is covered.
How to Keep Carpenter Ants From Coming Back
To keep carpenter ants out of your Long Island home, keep gutters clean and downspouts extended at least four feet from the foundation, flash deck ledgers correctly, replace any consistently damp trim, and cut tree branches at least six feet back from siding and roofline. In shoreline homes, watch window sills and door frames after heavy nor'easter rains. Bobby Bugs will flag every moisture source found during treatment so it can be repaired promptly.

Frequently asked questions
Carpenter ants vs termites: which do I have?
Carpenter ants leave clean, sanded-looking tunnels and small piles of coarse sawdust called frass, and workers are large and black. Termites leave mud tubes, hollowed wood packed with dirt, and swarm in spring. Both damage structure. A free inspection tells you which one, and the treatment is very different.
Do carpenter ants mean my house has water damage?
Often, yes. Carpenter ants on Long Island strongly prefer wood that has been softened by moisture, so nests commonly show up around leaking gutters, deck ledgers, poorly flashed windows, and shoreline homes with high humidity. Treatment includes finding and flagging the moisture source so the ants do not return.
Can carpenter ants destroy a house?
Yes, over years. Carpenter ants do not eat wood, but they excavate galleries inside it to nest, and mature colonies can span thousands of ants across multiple satellite nests. Left alone, they compromise sills, headers, and framing near moisture points. Treatment inside the first season of activity is almost always cheaper than repairs.
What does sawdust near baseboards mean?
Piles of clean, sawdust-like frass along baseboards, window sills, or in basements strongly suggests an active carpenter ant nest inside the wall or framing above. The frass is coarser than termite droppings and often mixed with wing fragments. A free Bobby Bugs inspection confirms location and severity.
