All-Natural Pest Control Services
for Long Island Homeowners
Scientific Horticulture brings family-owned expertise and garlic-based, eco-friendly treatments to Smithtown, Stony Brook, Port Jefferson, and communities across Suffolk County — protecting your yard without harsh chemicals.
Suffolk County Deserves Better Than Synthetic Chemicals
Long Island’s North Shore landscape — from the hardwood forests of Nissequogue to the shoreline neighborhoods of Poquott and Old Field — is too beautiful to treat with toxic pesticides. At Scientific Horticulture, every treatment is designed to protect your family, pets, and local ecosystem while delivering real results.
Why Garlic Oil?
Our signature garlic oil spray is a powerful, all-natural repellent that disrupts pest behavior without leaving synthetic residue in your soil or water table. It’s safe for honeybees, butterflies, and beneficial insects — something most conventional pesticide companies can’t say. It’s our difference, and our homeowners love it.
Our Pest Control & Landscape Protection Services
Each service is tailored for Long Island’s specific pest pressures, seasons, and soil conditions.
Tick & Flea Control
Suffolk County is one of the highest Lyme disease counties in New York. Our tick barrier treatments target deer ticks, lone star ticks, and fleas in their most active zones — tall grass, leaf litter, and wooded edges — before they reach your family or pets.
Mosquito Control
Summer on Long Island shouldn’t mean surrendering your backyard. Our mosquito treatments disrupt breeding cycles and eliminate adult populations in the vegetation where they rest — so you can actually enjoy your outdoor space from May through September.
Mite & Beetle Control
Spider mites, elm leaf beetles, and Japanese beetles are a regular threat to Long Island landscapes. Left unchecked, they strip foliage and weaken ornamental trees and shrubs over successive seasons. We treat early and effectively before populations explode.
Dormant Oil Treatments
Late winter is the most powerful time to act. Dormant oil applications smother overwintering scale, mite eggs, and adelgids on your trees and shrubs before they hatch in spring — giving you a head start on a pest-free season with a single all-natural treatment.
Deer Repellent Services
Deer pressure is intense across the North Shore — from Smithtown to Nissequogue, browsing deer can undo years of landscaping in a single winter. Our all-natural deer repellent applications create a scent barrier that reliably deters deer without fencing or harmful chemicals.
Inchworm Control
Spring inchworm outbreaks can defoliate mature oak, maple, and cherry trees within weeks. Our treatments use Dipel — a naturally occurring soil bacterium (Bt) — to stop caterpillar feeding before your trees experience the stress of full defoliation.
Tree & Shrub Pest Control
From scale insects and aphids to spongy moth caterpillars and hemlock woolly adelgid, Long Island trees face an ever-growing list of pest threats. Our comprehensive tree and shrub program covers all of it with eco-friendly, targeted treatments across the full growing season.
One-Time Party Spray
Hosting a summer barbecue, graduation party, or outdoor wedding in Suffolk County? Our one-time party spray gives you a single mosquito and tick treatment timed for your event — no seasonal commitment required. One flat fee, one application.
Protecting Long Island, Naturally
We believe pest control and environmental stewardship aren’t opposing goals — they’re the same goal.
Plant-Based Actives
Our garlic oil, Naturecide, and botanical-based treatments are derived from plants — not synthetic petrochemicals — and break down naturally in the environment.
Pollinator Safe
We apply treatments in the early morning or evening and avoid bloom periods to protect honeybees, native bees, and the butterflies that make Long Island gardens thrive.
Protecting Long Island Water
Our area sits above a sole-source aquifer. We use natural, low-runoff treatments that won’t leach synthetic chemicals into the groundwater Suffolk County depends on for drinking water.
Safe for Wildlife
From the raptors of Nissequogue to the shorebirds of the Long Island Sound coastline, our treatments are non-toxic to birds, mammals, and aquatic life when applied as directed.
The Long Island Difference
Family-Owned & Local
We’re not a franchise. We’re a Suffolk County family business that knows these neighborhoods, these trees, and these pest pressures firsthand.
Seasonal Timing Expertise
Pest control on Long Island is seasonal. We know when to act — from dormant oil in February to tick barriers in April to mosquito programs through September.
100% All-Natural Treatments
Every product in our program is plant-derived, OMRI-listed, or naturally occurring. No synthetic pyrethroids. No organophosphates. No compromise.
Customized for Your Property
A quarter-acre in Smithtown has different needs than a wooded acre in Nissequogue. We assess your property and build a program that makes sense for your landscape.

Pest problems don’t observe business hours. We’re available Monday through Sunday, 8 AM to 5 PM, to schedule service or answer questions.
