Dormant Oil — Your Most Powerful Late-Winter Investment
The most effective time to control scale, mite eggs, and adelgids on your trees and shrubs is before they hatch. Our late-winter dormant oil applications smother overwintering pests on the branch while plants are still dormant — a single treatment that pays dividends all season.
Understanding the Risk on Long Island
Local conditions in Suffolk County create specific pest pressures that homeowners shouldn’t underestimate.
Timing Is Everything
Dormant oil is most effective when applied after the hardest freezes but before bud break. That narrow late-winter window — roughly February through early April on Long Island — is when overwintering pest eggs are most vulnerable.
Prevention Over Cure
Scale insects, woolly adelgids, and mite eggs are far easier to eliminate in their overwintering stage than after they hatch and populations explode. One dormant application can prevent 3–4 summer treatments.
Hemlock Woolly Adelgid
Hemlock woolly adelgid is devastating Long Island’s eastern hemlock population. Dormant oil is one of the most effective and environmentally responsible tools available for adelgid management.
Safe for Beneficial Insects
Applied before bloom and before pollinators become active, dormant oil treatments have minimal impact on beneficial insect populations — one of the most ecologically responsible timing windows in pest management.
How We Treat Your Property
Every application follows a structured, science-backed process — no guesswork, no unnecessary treatments.
Pre-Treatment Inspection
We inspect targeted trees and shrubs for overwintering pest populations — scale crawlers, mite egg masses, adelgid ovisacs, and aphid eggs — and confirm bud break status to establish optimal application timing.
Full Coverage Application
Thorough coverage of all branch surfaces, bark crevices, and bud scales is essential. Our technicians apply horticultural oil at the correct dilution to ensure complete coverage without phytotoxicity risk.
Spring Follow-Up
We recommend a post-bud-break inspection 4–6 weeks after dormant oil application to assess emergence of any surviving populations and determine whether a targeted follow-up treatment is warranted.
All-Natural. Every Time.
Every product we use in our dormant oil treatments program is plant-derived, naturally occurring, or OMRI-listed for organic use. We made a commitment when we started this company: no synthetic pyrethroids, no organophosphates, no compromise on the health of your family or Long Island’s ecosystem.
Complete Your Yard Protection
Our services work best together. Many Long Island properties benefit from combining two or three programs for full seasonal coverage.
