Lyme Disease and Deer Ticks on Long Island: A Homeowner's Prevention Guide

Long Island has one of the highest concentrations of deer ticks — and one of the highest rates of Lyme disease — in the United States. This guide covers the risks and the most effective prevention strategies.

Why Long Island Has So Many Deer Ticks

Long Island's mix of dense suburban yards backing up to wooded edges, large deer populations, and abundant white-footed mice creates the perfect ecosystem for blacklegged (deer) ticks. The Hamptons, Brookhaven, Smithtown, and Huntington see particularly high tick density.

How Lyme Disease Spreads

Deer ticks pick up the Lyme bacterium from infected mice in their nymphal stage, then pass it to humans through bites — often when the tick is still small and easily missed. Most Lyme cases come from nymphal-stage tick bites in late spring and early summer.

Yard Strategies That Work

• Maintain a 3-foot wood chip or gravel barrier between lawn and woods
• Keep lawns short and remove leaf litter
• Stack firewood neatly and away from the house
• Discourage deer with fencing or landscaping
• Schedule professional tick yard treatment
• Add deer tick tubes to interrupt the life cycle

Personal Protection

• Wear long pants tucked into socks in tick zones
• Use EPA-registered repellents
• Check yourself, kids, and pets thoroughly after outdoor time
• Shower within two hours of coming indoors
• Run outdoor clothing through a hot dryer for 10 minutes

If You're Bitten

Remove the tick promptly with fine-tipped tweezers, save it in a sealed bag for testing, and watch for the characteristic bullseye rash. See your doctor if any symptoms develop.

Yard Treatment Is the Highest-Impact Step

For Long Island families, regular yard treatment is the single most effective long-term Lyme prevention strategy. Pair with personal precautions for layered protection.
