When we handle a silverfish infestation in New York City, the process starts with a thorough inspection not a quick walkthrough, but a real assessment of where silverfish are harboring, what moisture conditions are sustaining them, and how they’re moving through your home or building.
From there, we apply residual treatment to the harborage areas that matter: wall voids, cracks and crevices, under baseboards, bathroom vanities, basement corners. These are the places silverfish actually live, not just the surfaces they cross. We also apply NYS DEC registered materials that keep working after we leave.
After treatment, we set up a maintenance schedule weekly, monthly, or bi-monthly depending on what your situation calls for to replenish materials over time and make sure the infestation doesn’t quietly rebuild. That follow-through is what separates a real solution from a temporary fix. Most customers start seeing results within one to two weeks, with full elimination typically achieved within three to four weeks.
