Mosquito Control in Nassau County

Mosquito control in Nassau County typically costs $300 to $600 for a full season of protection, with individual treatments running $75 to $150 per application. Most homeowners opt for a seasonal plan that includes treatments every 3–4 weeks from late April through October, providing consistent protection during Long Island's peak mosquito months.

Service Options and Pricing

• Seasonal mosquito program: A full-season plan typically includes 6–8 treatments from spring through fall. Pricing ranges from $300–$600 depending on yard size and treatment frequency. This is the most cost-effective approach and provides the most consistent relief.
• Individual treatments: One-time applications for special events (outdoor weddings, graduation parties, barbecues) or occasional use cost $75–$150 per visit. These provide 2–3 weeks of significant mosquito reduction.
• Mosquito misting systems: Permanent automated misting systems installed around the property perimeter are a premium option at $1,500–$3,000+ for installation, plus ongoing maintenance and refill costs. These are most common at larger properties in areas like Sands Point, Brookville, and Old Westbury.

What Affects Mosquito Control Pricing

Yard size is the primary cost driver — larger properties require more product and application time. Properties adjacent to marshlands, retention ponds, or other standing water sources (common along Nassau County's South Shore and bay communities like Merrick, Bellmore, and Massapequa) face heavier mosquito pressure and may benefit from more frequent treatments. Heavily landscaped yards with dense shrubbery, ground cover, and shade areas provide more mosquito resting habitat and require more thorough application. Properties with pools, birdbaths, ornamental ponds, or poor drainage need additional attention to breeding site management.

A seasonal mosquito program from Nassau County Pest Control includes targeted barrier spray treatment of vegetation, shrubs, and shaded resting areas; larvicide application to standing water sources that cannot be eliminated; breeding site identification and recommendations; and treatments timed to Nassau County's specific mosquito activity cycles.

While a few mosquitoes in the yard are a normal part of Long Island summer life, there's a clear point at which professional mosquito control becomes necessary for both comfort and health safety. Here's how to assess your situation in Nassau County.

Signs You Need Professional Mosquito Control

• You can't use your outdoor spaces: If mosquitoes are preventing you from enjoying your deck, patio, pool area, or yard during summer evenings, professional treatment can dramatically improve your outdoor quality of life. You shouldn't have to choose between going outside and getting bitten.
• Multiple bites in short outdoor periods: Getting bitten within minutes of stepping outside indicates a heavy local mosquito population that DIY remedies like citronella candles and personal repellents cannot adequately address.
• Standing water you can't eliminate: If your property has drainage issues, low spots that collect rainwater, ornamental water features, or borders marshland or waterways, professional larvicide and source reduction services are needed.
• Outdoor events planned: Weddings, parties, graduations, and other outdoor events in Nassau County during mosquito season benefit enormously from a professional barrier treatment 24–48 hours beforehand.

Public Health Triggers

When Nassau County's Mosquito Control Division reports elevated West Nile Virus or EEE activity — typically announced through public health advisories during summer and early fall — homeowners should take mosquito protection seriously. These mosquito-borne illnesses pose genuine health risks, particularly to adults over 50, young children, and immunocompromised individuals. Professional yard treatment combined with personal protection measures significantly reduces your household's exposure risk.

Seasonal Timing on Long Island

Mosquito season in Nassau County runs from late April through October, with peak activity from June through September. The optimal time to start a seasonal treatment program is late April or early May, before mosquito populations build to their summer peak. Starting treatments early disrupts the reproductive cycle and keeps populations lower throughout the season. The Asian tiger mosquito, which is an aggressive daytime biter increasingly common across Nassau County, extends active biting hours beyond the traditional dusk period.

DIY vs. Professional

DIY measures like eliminating standing water, maintaining screens, and using personal repellent are valuable complements to professional treatment but cannot replace it when mosquito pressure is high. Store-bought yard sprays provide limited, short-duration protection compared to professional barrier treatments that use microencapsulated products designed to adhere to vegetation and remain effective for weeks. For comprehensive seasonal protection, call Nassau County Pest Control at (516) 517-9150. We serve every community in Nassau County from Elmont to Oyster Bay.

Effective mosquito control is part science, part local knowledge, and part consistent execution. Nassau County's geography — bordered by bays, crossed by creeks and canals, and dotted with marshlands — creates ideal mosquito breeding conditions that require an experienced, knowledgeable provider to manage.

Credentials to Verify

• NYSDEC Commercial Pesticide Applicator License: Mosquito control products, including adulticides and larvicides, are regulated pesticides that require DEC certification for commercial application. The applicator should hold appropriate category certification for outdoor pest management.
• Knowledge of local mosquito species: Nassau County is home to multiple mosquito species including Aedes albopictus (Asian tiger mosquito), Culex pipiens (northern house mosquito), and various salt marsh species. Each has different breeding habits, flight ranges, and active periods. Your provider should be able to identify the predominant species on your property and tailor their approach accordingly.
• Awareness of public health mosquito programs: Nassau County operates its own Mosquito Control program through the Department of Public Works, which conducts surveillance, larviciding of public waterways, and adulticiding when arbovirus activity (West Nile virus, Eastern Equine Encephalitis) is detected. Your private provider should coordinate their approach with this public program, not duplicate or conflict with it.

Questions to Ask

What products do you use, and are they safe for pets, children, and pollinators? How do you minimize impact on beneficial insects like bees and butterflies? What is your treatment schedule, and how does it align with Nassau County's mosquito season? Do you address breeding sites in addition to spraying for adult mosquitoes? What happens if it rains right after a treatment — do you re-treat?

Red Flags

Avoid providers who only spray for adult mosquitoes without addressing breeding sites — this is like bailing water without fixing the leak. Be cautious of companies that use broad-spectrum products without regard for pollinators and beneficial insects; responsible mosquito control uses targeted applications and timing to minimize non-target impact. Avoid anyone who claims to "eliminate all mosquitoes" — the goal of residential mosquito control is significant reduction, not total eradication, which is impossible in Nassau County's wet environment.

Mosquito control in Nassau County is uniquely regulated because it intersects public health, environmental protection, and pesticide law. With Nassau County operating its own government mosquito control program alongside private providers, understanding the regulatory landscape is essential.

Nassau County Government Mosquito Control Program

Nassau County operates one of the most active municipal mosquito control programs in New York State through the Department of Public Works, Mosquito Control Division. This program conducts countywide surveillance, monitoring mosquito populations and testing for arboviruses including West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE). When virus activity reaches threshold levels, the county may conduct truck-mounted adulticiding in affected areas. Private mosquito control providers must be aware of this program and coordinate their activities accordingly to avoid excessive pesticide application.

NYSDEC Regulations

All commercial mosquito control applications in Nassau County require NYSDEC certification. The DEC regulates which products can be used, where they can be applied, and how they must be documented. Key requirements include:

• All products must be EPA-registered and applied according to label directions
• Buffer zones must be maintained around water bodies, wetlands, and other sensitive areas — critical in Nassau County given our extensive coastline and bay ecosystems
• Application records must be maintained for three years
• The DEC may impose additional restrictions during mosquito-borne disease outbreaks

Environmental Protection Considerations

Nassau County's proximity to coastal ecosystems — including the Hempstead Bay, South Oyster Bay, and protected wetlands — creates heightened environmental sensitivity for mosquito control activities. Providers must comply with federal Clean Water Act requirements and avoid contamination of waterways. The use of Bti (Bacillus thuringiensis israelensis) larvicide is preferred in environmentally sensitive areas because it targets mosquito larvae specifically without harming fish, birds, or other aquatic organisms.

Pollinator Protection

New York State has taken increasing steps to protect pollinators, including honeybees and native bees. While there is no outright ban on mosquito control products that affect pollinators, best practices endorsed by the DEC include applying products at dawn or dusk when pollinators are less active, avoiding direct application to flowering plants, and using the most selective products available. Nassau County Pest Control follows all pollinator protection best practices and can discuss specific measures we take to protect beneficial insects on your property.
