Ant control in Park Slope: what to know
Park Slope's signature brownstones and limestone row houses are beautiful and old — the same deep voids, shared walls and original plumbing that make them charming also make them prone to rodents, ants and cockroaches moving between floors and homes.
The neighbourhood's location on the edge of Prospect Park means added seasonal pressure from rodents, mosquitoes and ticks, and from outdoor ants foraging indoors in warm months.
Family-dense brownstone blocks and the restaurant corridors along Fifth and Seventh Avenues keep food-source pressure high year-round.

How we treat ant control in Park Slope
Carpenter ants (Camponotus pennsylvanicus) are the large black ant species NYC residents actually need a licensed exterminator for — pavement ants foraging for crumbs are a nuisance, but carpenter ants excavate galleries in wood, and finding the parent colony behind that damage takes trained inspection, not a can of spray.
Since 2006, our technicians have learned to read NYC's building stock for the moisture patterns carpenter ants exploit: pre-war brownstone floor joists near grade, flat-roof parapet failures, window sills softened by condensation. The colony you see in the kitchen is usually a satellite; the parent nest sits in the moisture-damaged void feeding it. Treating only what's visible is why DIY attempts fail, and why so many customers call us after a previous provider's spray wore off in weeks.
