Ant Extermination in Harrison
Ants are the most common pest complaint in Harrison and throughout Westchester County, especially in spring and summer when colonies send foragers into homes seeking food and moisture. While most ant species are a nuisance, carpenter ants pose a genuine structural risk to Westchester's older housing stock — particularly homes with aging wood, past water damage, or mature trees nearby.Westchester County Pest Control provides professional ant extermination that targets the entire colony, not just the foragers you can see.
Ant Species Common in Harrison
- Carpenter Ants (Camponotus pennsylvanicus): The most important structural pest ant in Westchester County. Large and black, they excavate galleries in moist or damaged wood. Spring emergence of large ants indoors — especially near windows, in bathrooms, or near a fireplace — is a warning sign. Harrison's wooded setting and older homes make carpenter ant management a top priority.
- Pavement Ants (Tetramorium caespitum): Small, dark ants that nest in soil under pavement, driveways, and foundation walls. Common in Harrison's older neighborhoods. They forage into kitchens for sweets and greasy foods.
- Odorous House Ants (Tapinoma sessile): Small, dark brown ants that smell like rotten coconut when crushed. Nest in wall voids, under flooring, and in insulation. Highly persistent — colonies split under pressure from repellent sprays.
- Acrobat Ants & Citronella Ants: Less common but present in wooded areas of Westchester County. May swarm indoors in late summer.
Why Perimeter Spray Alone Doesn't Work
Many homeowners buy perimeter spray products that kill foragers but never reach the queen. The colony simply sends new foragers from a different direction within days. Effective ant control requires slow-acting bait — either gel bait or granular bait — that foragers carry back to the colony, poisoning the queen and brood. For carpenter ants, we supplement bait with direct void treatments and dust injections into satellite colonies inside the structure.

Are carpenter ants destroying my home in Harrison?+
Carpenter ants are the most structurally damaging ant species in Westchester County. Unlike termites, they don't eat wood — they excavate smooth galleries in soft, moist, or decayed wood to nest. Common locations include window frames, door frames, porch columns, and areas around roof leaks or plumbing failures. Large (¼–½ inch), black carpenter ants seen indoors in spring, especially in large numbers, indicate a satellite colony inside the structure. Finding the parent colony — often in a tree stump, wood pile, or fence post within 100 yards — is critical for complete elimination.
