Stop Deer Damage with All-Natural Repellent Applications

Deer browsing pressure on Long Island’s North Shore is intense — especially from November through April when natural food sources are scarce. Our Deer Out and garlic oil applications create a persistent scent barrier that reliably deters deer without fencing, chemicals, or harm to wildlife.

Understanding the Risk on Long Island

Local conditions in Suffolk County create specific pest pressures that homeowners shouldn’t underestimate.

North Shore Deer Pressure

The wooded neighborhoods of Nissequogue, Head of the Harbor, Stony Brook, and Setauket experience some of the highest deer density on Long Island. Without deterrents, browsing damage to ornamental plantings is nearly certain each winter.

Investment Protection

A single winter of unchecked deer browsing can destroy arborvitae hedges, rhododendrons, and ornamental plantings that took years to establish. Prevention is far less expensive than replacement.

No Fencing Required

Our scent-based deterrents work through deer’s acute sense of smell — the most effective non-physical repellent mechanism available. Applications are invisible and don’t alter the appearance of your landscape.

Seasonal Reapplication

Repellent efficacy diminishes with rainfall and new plant growth. We schedule reapplication at intervals matched to your local deer pressure and the season to maintain consistent protection through peak browsing months.

How We Treat Your Property

Every application follows a structured, science-backed process — no guesswork, no unnecessary treatments.

1

Landscape Assessment

We identify the most vulnerable plantings — arborvitae, yew, rhododendron, hosta, and young ornamentals — and map deer entry corridors to focus treatment where it matters most.

2

Repellent Application

Deer Out and garlic oil are applied directly to foliage and branch tips — the deer’s primary browsing targets. The scent is undetectable to humans at a few feet but highly aversive to deer.
