Plant-based, family-safe barrier spray treatments for Nassau County, Suffolk County, and the Hamptons. Seasonal programs and one-time event spraying.
Long Island's warm, humid summers create ideal breeding conditions for mosquitoes and deer ticks — two of the most persistent threats to outdoor enjoyment and family health. Cardi Design & Build offers professional organic mosquito and tick barrier spray treatments that protect your property throughout the season using plant-based, family-safe formulations.
Our organic program uses essential oil formulations — cedar oil, rosemary, peppermint, and clove — that are highly effective against mosquitoes and ticks while being safe for children, pets, and the pollinators that Long Island gardens depend on. Treatments are applied by our licensed technicians to the perimeter of your property, targeting shrubs, ground cover, wood edges, and leaf litter where mosquitoes and ticks harbor.
As a full-service landscape design and build company, Cardi Design & Build brings a unique advantage to pest control: we understand your property's landscape. Our technicians treat with precision — targeting the specific areas where ticks and mosquitoes concentrate — rather than blanket-spraying the entire yard.
Our organic treatments use essential oil formulations — cedar oil, rosemary, peppermint, and clove — that are highly effective against mosquitoes and ticks without synthetic chemicals.
Organic barrier sprays are safe for children and pets once dry, typically within 20–30 minutes. No need to vacate your property for hours after treatment.
Unlike synthetic pyrethroid sprays, our organic formulations do not harm bees, butterflies, or beneficial insects when applied correctly — critical for Long Island's garden landscapes.
Our organic program provides 14–21 days of protection per treatment. Seasonal programs run May through October with treatments every 3 weeks for continuous coverage.
Full-season organic coverage from May through October. Treatments every 21 days using plant-based barrier sprays. Ideal for families with young children, pets, or pollinator gardens. Covers all of Nassau County and Suffolk County.
Professional-grade synthetic barrier spray for maximum mosquito and tick knockdown. EPA-registered products applied by licensed technicians. Treatments every 21 days from May through October.
Planning a backyard party, graduation, wedding, or outdoor event? A single treatment 24–48 hours before your event creates a mosquito and tick-free environment for your guests. Available in organic or conventional formula.

Most mosquito and tick companies treat every property the same way — a blanket spray of the entire yard on a fixed schedule. Cardi Design & Build takes a different approach. Because our team designs and builds Long Island landscapes, we understand exactly where ticks and mosquitoes concentrate on your specific property.
We target treatments to the high-risk zones: the wood edges, the dense shrub borders, the areas with leaf litter accumulation, the shaded ground cover near the pool — the places where deer ticks and mosquitoes actually live. This precision approach means better results with less product applied.
Our organic program is particularly well-suited to the estate-scale properties we serve across Nassau County's Gold Coast and Suffolk County — large properties with mature plantings, pollinator gardens, and children and pets who use the outdoor spaces daily.

Organic barrier sprays using essential oil formulations are highly effective against mosquitoes and ticks, though they may require slightly more frequent application than synthetic pyrethroids — every 14–21 days versus every 21 days. For most Long Island residential properties, organic programs provide excellent protection throughout the season.
Yes. Our organic spray program is safe for children and pets once dry, typically within 20–30 minutes of application. Our conventional program requires a 30–45 minute dry time. We recommend keeping children and pets off the treated lawn until the product has fully dried.
Yes. Our barrier spray treatments target both mosquitoes and ticks simultaneously. We treat the perimeter of your property, focusing on shrubs, ground cover, wood edges, and leaf litter — the primary harborage areas for deer ticks and dog ticks on Long Island properties.

Cardi Design & Build offers mosquito and tick control as part of a comprehensive landscape care program. Our team understands your property's landscape — the plantings, the drainage, the areas where ticks harbor — because we often designed and built it. This integrated approach means treatments are more targeted and effective than a standalone pest company that doesn't know your property.
