Carpenter ants are significantly larger than common household ants (up to ½ inch long) and are typically black or dark brown with a rounded thorax. Unlike termites, they don't eat wood but excavate it to build nests, leaving behind piles of sawdust-like material called frass. You may also hear faint rustling sounds inside walls or see large winged ants (swarmers) in spring, particularly near windows or wooden structures in your Hempstead home.

Yes, carpenter ants are very common throughout Hempstead and Nassau County due to the abundance of mature trees, older wooden homes, and Long Island's humid climate that creates moisture-damaged wood where colonies prefer to nest. The area's mix of residential properties near wooded areas like Hempstead Lake State Park and Cathedral Gardens provides ideal habitats for these pests to establish satellite colonies indoors, especially during spring and summer months.

Most Hempstead homeowners notice a significant reduction in carpenter ant activity within 7–10 days of initial treatment, with complete colony elimination typically achieved within 2–4 weeks. The timeline depends on colony size, location, and whether we're treating a parent colony or satellite nests. We often schedule follow-up visits to ensure all colonies are eradicated and provide ongoing monitoring to prevent re-infestation in your Long Island home.
