Ticks & Lyme Disease in Westchester & Rockland County: Identification, Risk & Control

Living with Tick Risk in the Hudson Valley — What Every Homeowner Needs to Know

Westchester County has long held a grim distinction: it is one of the counties with the highest rates of Lyme disease in the entire United States. Year after year, New York State Department of Health data shows Westchester and Rockland Counties among the top-affected areas in the nation. For families in communities bordering wooded areas — from Sleepy Hollow and Tarrytown along the Hudson to Stony Point and Haverstraw in Rockland — tick pressure isn't a seasonal concern. It's a year-round reality.

Understanding the ticks in our region, how to identify them, and what professional tick control can do for your yard is essential for protecting your family.

Tick Species in Our Region

Blacklegged Tick (*Ixodes scapularis*) — Deer Tick

The primary vector for Lyme disease, Anaplasmosis, and Babesiosis. Adults are approximately 3–5 mm (sesame seed sized), reddish-brown with a darker shield. Nymphs — the stage most likely to transmit disease — are the size of a poppy seed and nearly invisible. Deer ticks are active whenever temperatures are above freezing, making late fall and late winter tick checks a necessity. They prefer humid, leafy habitats — forest edges, overgrown lawns, and areas with heavy leaf litter.

American Dog Tick (*Dermacentor variabilis*)

Larger than deer ticks, patterned with white or yellow markings. Transmits Rocky Mountain Spotted Fever (rare but serious) and Tularemia. Most active spring through summer. More commonly found in open grassy areas than in dense woodland.

Lone Star Tick (*Amblyomma americanum*)

Identifiable by a single white spot on the female's back. An aggressive feeder that is expanding its range northward into our region. Associated with STARI (Southern Tick-Associated Rash Illness) and the alpha-gal red meat allergy syndrome.

The Biology of Lyme Disease Transmission

Lyme disease is caused by the bacterium *Borrelia burgdorferi*, transmitted through the bite of an infected deer tick. The tick must generally be attached for 36–48 hours to transmit Lyme — which is why daily tick checks are so important. Prompt removal within this window dramatically reduces infection risk.

In Westchester and Rockland, deer populations — and their associated tick loads — are substantial. The forested corridors of Harriman State Park, Palisades Interstate Park, and the numerous county and town parks create ideal habitat. Residential properties adjacent to woodlands, meadows, or even unmaintained areas along stone walls are at highest risk.

Infection rates in our region: Studies have found 20–50% of deer ticks in Westchester County positive for *Borrelia burgdorferi*. That's not trivial. Every tick bite in our region warrants prompt attention.

Property Risk Assessment: Is Your Yard High-Risk?

Your yard's tick risk depends on its characteristics:

Higher risk:

- Adjacent to or backing up to woodland or brush

- Significant leaf litter accumulation against the foundation or in garden beds

- Stone walls (rodent habitat = tick habitat)

- Tall grass or unmaintained vegetation

- Bird feeders or deer attractants

- Presence of deer, raccoons, or other wildlife hosts

Lower risk:

- Well-maintained lawn with defined border between grass and woodland

- No leaf accumulation

- Physical deer deterrents

- Reduced rodent habitat

If you're in a community like Rye, Bronxville, or New City with mature tree cover and abundant wildlife, your yard almost certainly falls in the higher-risk category.

Professional Tick Control for Your Property

BluesWay Pest Control offers targeted tick control services using methods that significantly reduce tick populations in your yard:

Perimeter Treatments

Targeted application of acaricides (tick-specific pesticides) along the lawn/woodland border, leaf litter areas, and foundation plantings. These treatments, applied 3–4 times seasonally (spring through fall), can reduce deer tick populations by 80–90% according to published research.

Granular Treatments for Rodent Hosts

The white-footed mouse (*Peromyscus leucopus*) is the primary reservoir for *Borrelia burgdorferi* — the bacteria ticks pick up before they can transmit it to humans. Biodegradable tick tubes containing permethrin-treated cotton (used by mice for nesting) kill larval ticks on rodents before they can become infected. This breaks the transmission cycle at its source.

Tick Inspection and Monitoring

Our licensed exterminator team can assess your property's specific risk areas and set up monitoring to track tick activity through the season.

What You Can Do on Your Own

Professional treatments work best in combination with property-level prevention:

• Mow regularly and keep grass under 3 inches

• Clear leaf litter from garden beds and foundation areas in fall

• Create a mulch or gravel barrier (3 feet wide) between lawn and wooded edges

• Stack woodpiles neatly away from the house in a dry, sunny location

• Remove bird feeders if deer are visiting your yard

• Conduct daily tick checks on all family members and pets after outdoor time

• Shower within 2 hours of coming indoors after outdoor activity — showering has been shown to reduce tick attachment

Personal Protection

Even with professional yard treatment, personal protection during outdoor activity is essential:

- Apply EPA-registered repellent containing DEET (20–30%), picaridin, or IR3535

- Wear light-colored clothing to spot ticks more easily

- Tuck pants into socks and shirts into pants in high-risk environments

- Treat clothing and gear with permethrin (not for skin application)

Don't Wait — Tick Season in Westchester Is Year-Round

Deer ticks in our region are active whenever temperatures rise above 35–40°F. The commonly held belief that tick season is "just summer" is outdated and dangerous. We get calls about tick exposure from Westchester homeowners in January and February during mild spells.
