Ant control is among the most common pest issues we treat in Prospect Heights. The mix of historic brownstones and larger pre-war apartment buildings means both shared-wall ant and cockroach issues in the row houses and elevator-borne bed bug spread in the multi-storey buildings.
Ant control in Prospect Heights: what to know
Prospect Heights sits on the northern edge of Prospect Park — the park's large green footprint is a major outdoor rodent and stinging-insect habitat that feeds pressure into the residential brownstone and apartment buildings immediately adjacent, particularly in autumn as conditions cool.
Vanderbilt Avenue's concentrated restaurant scene is one of Brooklyn's most active dining corridors; food-waste pressure from the strip drives rodent activity into the surrounding pre-war residential buildings along Washington and Underhill Avenues.

- Large black ants (12–25mm) foraging indoors, especially at night

- Soft or discoloured wood on original joists, sill plates, or basement framing
How we treat ant control in Prospect Heights
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.
