Mosquito Larva Control, New York City

The City Treats the Marshes. We Treat Your Property.

Every year, the NYC Health Department conducts aerial larviciding over marshes and wetlands in Brooklyn, Queens, the Bronx, and Staten Island. It’s a real program, and it helps — but it covers nonresidential areas only. Your backyard, your rooftop, your basement window well, your gutters? Those are on you. That’s where mosquito larvicide treatment comes in. Larviciding targets mosquitoes during the larval stage — while they’re still in standing water, before they emerge as adults and start biting. It’s the most efficient intervention available because larvae don’t move. They stay in the water where they hatched, which makes them far easier to eliminate than adult mosquitoes that scatter the moment you walk outside. We’ve been doing this work across Brooklyn, Queens, Manhattan, the Bronx, and Staten Island since 1971. New York City properties aren’t simple — flat brownstone rooftops, attached row house gutters, basement-level window wells, rooftop garden planters — each one is a potential breeding site that a quick pass with a hardware store dunk won’t find or fix.

What Changes After Larvicide Treatment

When you eliminate larvae before they emerge, you're not just reducing bites — you're cutting the population at the source, season after season.

You reclaim your outdoor space — backyard, stoop, rooftop — without being driven inside every evening.

Every larva eliminated is a biting adult that never exists, which means fewer mosquitoes across the entire season.

Professional-grade larvicide products provide 14–30 days of residual control in treated water sources, not just a one-day fix.

You get a property inspection that finds breeding sites you didn’t know about — clogged gutters, HVAC condensate lines, low-lying yard corners.

Only NYSDEC-registered materials are used, so your family, pets, fish, and garden aren’t at risk when treatment is applied correctly.

You’re ahead of the season, not reacting to it — larvicide applied before peak summer prevents population explosions, not just slows them down.

Brooklyn and Queens Have the Highest West Nile Burden in New York City

In 2024, Brooklyn and Queens each recorded 12 confirmed human West Nile disease cases — the highest of any borough in New York City. And in 2025, NYC mosquitoes tested positive for Jamestown Canyon virus for the first time. These aren’t distant statistics. They’re happening in the neighborhoods we’ve been treating for over five decades. Mosquito-borne illness isn’t something most New Yorkers think about until someone they know gets sick. But the public health data is clear, and the geography matters. If you’re in Brooklyn or Queens — especially near Jamaica Bay or in low-lying areas that flood after heavy rain — your property sits in some of the highest-pressure mosquito habitat in the city. Larvicide treatment applied at breeding sites before the season peaks is the proactive decision. Waiting until you’re already getting bitten means the population has already had weeks to compound. New York City’s mosquito season runs from April through October, and it’s getting longer. Warmer winters and earlier springs — documented by the NYC Health Department — are pushing the active season earlier each year. That’s not alarmism; it’s the pattern we’ve watched develop over 50-plus years of work in this city.

The Breeding Site You Haven't Found Yet

Mosquitoes can breed in water as small as a bottle cap. That’s not a figure of speech — the NYC Health Department uses that exact language in its public guidance. Which means emptying your birdbath and dumping the flower pot saucers, while helpful, rarely solves the problem. The standing water you don’t see is where the real issue lives. In New York City’s layered building stock, that means flat rooftop drains that never fully empty, clogged gutters in attached row houses where one blocked downspout affects the whole block, HVAC condensate lines that drip into corners, and basement window wells that collect rainwater with nowhere to go. These are breeding sites that a DIY mosquito dunk from the hardware store won’t reach — and that most homeowners never think to check. Before we apply anything, we inspect. We walk the property looking specifically for standing water — including the water you haven’t noticed. The inspection is the service. The larvicide is what we apply once we know exactly where the problem is. That distinction matters, and it’s why our approach gets results that a quick product application alone doesn’t.
