Carpenter Ant Control in Orange County, NY
Carpenter ants are large black ants that hollow out wood to build nests. They don't eat wood like termites, but long-term colonies can weaken window frames, decks, sill plates and roof eaves. Wooded lots common around New Windsor and Cornwall see heavy carpenter ant pressure.
Peak season: April through August
Signs of carpenter ants
- Large black ants (1/4"–1/2") inside, especially at night
- Small piles of coarse sawdust (frass) below wood trim or in basements
- Winged ants indoors in late winter or spring — a sign of a mature indoor colony
- Faint rustling inside walls
Why they choose your house
Carpenter ants prefer wood that's been softened by moisture: leaking window sills, rotted deck boards, roof leaks, and areas where gutters overflow. Trees touching the roof and stacked firewood give them easy bridges inside.
How we treat carpenter ants
- Inspect for nests and satellite colonies inside and out
- Treat nest galleries and travel routes directly

Frequently asked questions
Are carpenter ants the same as termites?
No. Termites eat wood; carpenter ants excavate it to nest. Both cause damage but need different treatments, so correct identification matters.
Do carpenter ants mean I have rotted wood?
Often, yes — they favor moist or damaged wood. We'll point out what we find so you can address it.
