Ant control in Carroll Gardens: what to know
Carroll Gardens is known for its unusually deep front gardens on brownstone-lined streets between Court and Smith — a variant of the classic Brooklyn row house with the same shared walls, old plumbing and basement voids that let rodents and cockroaches travel between adjoining homes.
The gardens and mature street trees add seasonal ant and occasional-invader pressure, while the busy Smith Street and Court Street restaurant strips sustain rodent pressure into the surrounding residential blocks.

How we treat ant control in Carroll Gardens
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.
