Mosquito Control for Scarsdale Homes
Westchester has two distinct mosquito species with different breeding habits. Effective control means targeting both. That takes barrier spray, larvicide, and a 21-day re-treatment cycle all season.
Quick answer: Mosquito control here means barrier spray on vegetation and larvicide for standing water. One application suppresses adult mosquitoes for about 21 days. Full-season coverage means re-treating on that cycle from May through September.
What's Included
Our Mosquito Control Service Includes
Property inspection identifying standing water and active breeding sites across the yard
Larvicide treatment of water features, catch basins, gutters, and low spots
Barrier spray to perimeter vegetation, understory shrubs, and shaded resting areas
Scheduled re-treatment every 21 days through the active season
Habitat modification recommendations to eliminate breeding sources
Single-event treatments are also available for one-off outdoor gatherings, weddings, and parties
Mosquito Pressure in Westchester: What You're Actually Dealing With
Two mosquito species drive most complaints in Westchester County, and they behave very differently. Culex pipiens, the Northern house mosquito, is the primary West Nile virus vector here.
It breeds in stagnant, organic-rich water. Clogged gutters, birdbaths, and low spots that hold rain all qualify.
So do catch basins and containers holding water for a few days. Culex is most active at dusk and dawn.
Aedes albopictus, the Asian tiger mosquito, is a tougher pest to manage. Unlike Culex, it bites aggressively during the day.
It breeds in tiny water volumes. Tree holes, leaf axils, flower pot saucers, even a bottle cap of rainwater all work.
Tiger mosquitoes arrived in Westchester in the mid-1990s. They're now the dominant nuisance species in local yards.
Controlling them takes thorough breeding-site elimination plus repeated barrier treatments. New adults keep emerging from hard-to-find micro-sources.
Effective mosquito management addresses both species at once. Larvicide applications to identified water sources interrupt the Culex breeding cycle at the source.
Barrier spray targets vegetation and shrubs where both species rest by day. It knocks down adult populations fast and leaves residual protection behind.
Pyrethrin-based products break down with rain and UV, so 21-day re-treatment isn't optional. It's what keeps suppression continuous between visits.
When Mosquitoes and Ticks Overlap
Worried about deer ticks and Lyme disease too? Our LymeShield program pairs the same barrier spray with targeted deer tick nymph treatment. It runs through spring and summer.
It's the more complete option for wooded or deer-heavy properties. Standalone mosquito control fits properties that have already handled tick risk separately. It also suits homeowners who want seasonal coverage for one stretch or event.
Where the Pressure Comes From Locally
Westchester's wetland corridors act as regional mosquito breeding reservoirs. That's especially true for properties along the Bronx River and its smaller tributary streams.
Nearby neighborhoods feel the higher baseline pressure most. That includes parts of Scarsdale, Eastchester, Ardsley, and Bronxville.
Our site inspection pinpoints the breeding sources on your property. It also flags whether the pressure is on-site or drifting in from nearby wetlands. That distinction shapes the treatment plan.
Mosquito-Borne Disease Risk in Scarsdale
Beyond the nuisance factor, mosquito exposure carries real health risk for families and pets. Westchester County is a recognized surveillance zone for these threats.
- West Nile virus, tracked annually by the Westchester County Health Department and transmitted by Culex mosquitoes breeding in stagnant water.
- Eastern Equine Encephalitis, a rare but serious neurological infection found in wooded wetland corridors near Westchester.
- Dog heartworm (Dirofilaria immitis), transmitted to dogs and cats through a single mosquito bite.

Our Process
How Our Mosquito Control Process Works
Site Inspection & Breeding Source Mapping
We walk the entire property identifying standing water sources, drainage issues, resting habitat in dense vegetation, and evidence of high mosquito activity. Breeding sources are documented and prioritized for larvicide treatment.
Larvicide Treatment
EPA-registered larvicide products, including Bti (Bacillus thuringiensis israelensis) granules for organic water sources, are applied to gutters, water features, catch basins, and any standing water that cannot be drained. Larvicide interrupts the breeding cycle before adults emerge.
Barrier Spray Application
Pyrethrin-based barrier spray is applied to the undersides of leaves, perimeter shrubs, tree lines, and shaded resting areas where mosquitoes shelter during the day. Treatment targets both Culex and Asian tiger mosquito resting habitat.
21-Day Re-Treatment & Monitoring
Scheduled re-treatments every 21 days maintain barrier effectiveness as products naturally degrade. Each visit includes a reassessment of breeding sources, removal of any new standing water, and updated larvicide applications as needed.
The 4 steps aren't a one-time sequence. Step 4 loops back into step 3 every 21 days for the whole active season.
