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
Park Slope's brownstone and limestone row houses are largely late-19th to early-20th-century construction, with original timber floor joists and, on many blocks, masonry that's original or only partially renovated. That combination — old wood, old brick, mortar gaps that were never resealed — gives carpenter ants exactly the moisture-damaged material they need to excavate a colony.
The ants foraging across a kitchen counter are rarely the whole story. In row houses this old, the parent colony is more often in a damp basement or garden-level void, a deteriorated sill plate, or a section of original floor joist that's held moisture behind unrenovated masonry for years. Treating only what's visible upstairs is why a DIY approach tends to fail season after season.
