Carpenter Ant Control on the Nassau South Shore

Carpenter ants are damaging structural wood in homes across Long Beach, Freeport, and the Nassau South Shore. Here's how to identify and eliminate them.

# Carpenter Ant Control on the Nassau South Shore

If you're seeing large black ants β€” up to half an inch long β€” inside your Freeport kitchen, emerging from a wall void in Oceanside, or trailing across your Merrick deck, you likely have carpenter ants. They don't eat wood like termites β€” but the galleries they excavate in moisture-softened structural timber can cause serious damage if left untreated for years.

Why the South Shore Is High-Risk

Moisture and wood decay: Carpenter ants strongly prefer wood softened by moisture. The South Shore's coastal environment β€” elevated humidity, salt air, and direct water exposure in waterfront communities β€” accelerates wood deterioration. In Freeport, Hewlett Bay Park, Atlantic Beach, and Lawrence, we routinely find carpenter ant galleries in deck joists, porch framing, and basement sill plates with years of moisture exposure.

Tree proximity: Large mature trees in Rockville Centre, Merrick, and Baldwin often harbor carpenter ant parent colonies. Satellite colonies extend from these trees into nearby structures. Removing infested trees and stumps is sometimes necessary.

Older construction: Homes built in the 1940s–1970s throughout the South Shore have original wooden structures that have accumulated decades of moisture exposure β€” prime carpenter ant habitat.

Warning Signs

β€’ Frass: Pale sawdust-like material near wall openings, windowsills, or on basement floors β€” carpenter ant excavation debris

β€’ Large black ants indoors: Especially in spring when foragers become active

β€’ Rustling in walls: Distinctive papery sound of ants excavating wood galleries, audible at night

β€’ Winged ants in spring: Carpenter ant swarmers (April–June) are larger than termite swarmers, with unequal wing length and a distinctly pinched waist

Professional Treatment

Effective treatment requires locating the colony (not just spraying perimeter), injecting residual insecticide directly into galleries to reach the queen, exterior perimeter treatment to prevent reinfestation, and identifying and correcting the moisture source that created the vulnerable wood.
