Over-the-counter products are built for the pest you can see. That’s their design limit. They can’t reach the nesting sites behind your walls, the egg masses tucked under appliances, or the entry points that keep letting new pests in after each treatment.
If you’ve sprayed, seen results for a week or two, and then watched the problem come back — that’s not bad luck. That’s how OTC products work.
Professional home bug treatment in New York City addresses the full picture. We locate harborage areas. We identify entry points. We treat the cycle, not just the visible population. For a single-family home in neighborhoods like Marine Park, Bay Ridge, or Howard Beach — where your house sits on its own foundation with its own perimeter — that distinction matters more than it would in a high-rise apartment where the building’s infrastructure is someone else’s concern.
The homes we service most often in Brooklyn and Queens are pre-war and post-war construction with decades of accumulated gaps: old plumbing penetrations, deteriorated mortar, original window frames that haven’t sealed properly in years. These aren’t cosmetic issues. They’re pest highways, and no spray-and-leave treatment closes them.
