Quick Guide: the 60-second version
On Long Island, ticks concentrate in edges: wooded borders, leaf litter, trail-side vegetation, and dense landscaping. If you want fewer ticks, focus on the edges first.
- Blacklegged (deer) tick: tiny; the main Lyme disease concern. Leaf litter and shaded edges.
- Lone star tick: female often has one white dot; aggressive biter, expanding regionally.
- American dog tick: larger; grassy edges, trails, and fields.
- Asian longhorned tick: invasive and monitored in NY; found more often on animals than on people.
After any outdoor time near edges or brush: do a full tick check, shower, and toss clothes in a hot dryer. Found a tick? Remove it with fine-tipped tweezers, save it in a sealed container, and watch for symptoms.
Why Long Island Gets So Many Ticks
Long Island has a mix of conditions ticks love: humid coastal air, shade from mature trees, wooded preserve trails, deer and rodent activity, and neighborhoods where lawns blend into natural edges. You do not need to live deep in the woods to have ticks. All it takes is a few connected hot zones: leaf litter under shrubs, a brushy fence line, or a trail edge your dog brushes on every walk.
The pattern is especially strong in communities with greenbelts, preserve access, or yards that back to woods. If you have ever found a tick after a quick moment outside, that is the edge effect in action: ticks wait where hosts pass, and hosts pass where people like to walk.
Tick-Borne Diseases Tracked in New York
New York State public health resources list several tick-borne diseases of concern statewide, including Lyme disease, anaplasmosis, babesiosis, ehrlichiosis, Rocky Mountain spotted fever, and Powassan virus. Knowing this list matters because it explains why identification and prevention get so much attention on Long Island.
Different ticks are associated with different pathogens. Suffolk County’s tick information materials specifically note that blacklegged (deer) ticks can transmit Lyme disease, anaplasmosis, babesiosis, Borrelia miyamotoi disease, and Powassan virus disease, which is one reason deer tick education is a big local focus.
Quick ID Chart: Long Island Ticks at a Glance
Built for busy homeowners. Deeper detail on each species follows below.
| Tick | Scientific name | What it is known for | Common Long Island hot zones |
|---|---|---|---|
| Blacklegged (deer) tick | Ixodes scapularis | Tiny nymphs; strongly linked to Lyme disease in NY | Leaf litter, shaded edges, wooded borders, under shrubs |
| Lone star tick | Amblyomma americanum | Aggressive biter; expanding regionally; alpha-gal discussions | Brushy edges, wooded transition zones, overgrown borders |
| American dog tick | Dermacentor variabilis | Larger; common along trails and brushy edges | Grassy edges, paths, trail borders, fields |
| Asian longhorned tick | Haemaphysalis longicornis | Invasive; monitored in NY; less attracted to humans than native ticks | Varies; reported more often on animals than on people |
Blacklegged (Deer) Tick
The blacklegged deer tick (Ixodes scapularis) is the tick most associated with Lyme disease in New York and the Northeast. It is often hard to spot, especially the nymphs, and it is commonly picked up in shaded, brushy, or leaf-litter areas.
Quick ID clues
- Size: nymphs are poppy-seed sized and easy to miss.
- Color: dark legs; adults have a darker shield near the head.
- Where they hide: leaf litter, shady edges, woods borders, under shrubs, fence lines.
Why nymphs matter
Nymphs are tiny and easy to miss, which is one reason many infections occur: people do not notice a tick until after it has been attached. This is also why tick checks after yard time and trail time matter so much on Long Island. Suffolk County notes blacklegged ticks can transmit Lyme disease, anaplasmosis, babesiosis, Borrelia miyamotoi disease, and Powassan virus disease.
Lone Star Tick
The lone star tick (Amblyomma americanum) is expanding in many areas and is frequently discussed on Long Island. Adult females often have a distinctive single white dot (“lone star”) on their back.
Quick ID clues
- Female marking: often a single white dot on the back.
- Behavior: aggressive biter; can be persistent about finding hosts.
- Habitat: brushy edges, woods borders, overgrown perimeter zones.
Lone star ticks are associated with ehrlichiosis and are linked in public health discussions to alpha-gal syndrome (a red meat allergy) in some cases. For identification photos, bite steps, and yard prevention specific to this tick, see our lone star tick guide.
American Dog Tick
The American dog tick (Dermacentor variabilis) is larger than deer ticks and is often encountered along grassy edges and brushy areas. CDC resources list the American dog tick among species that spread Rocky Mountain spotted fever, and CDC tularemia guidance also notes it can transmit tularemia.
Quick ID clues
- Size: adults are generally larger than blacklegged ticks.
- Look: often ornate patterning on the shield.
- Where they hide: grassy and brushy areas, trail edges, fields, paths.
Trail tip: trail edges are classic dog tick territory. Stay centered on trails when you can, and do a quick tick check after every outing.
Asian Longhorned Tick (What Long Island Homeowners Should Know)
The Asian longhorned tick (Haemaphysalis longicornis) is an invasive tick that has been detected in New York. New York State issued a public announcement in 2018 about the longhorned tick being found in the state, and agencies continue monitoring it.
What to know
- Invasive and monitored: detected in New York; researchers continue studying its role in pathogen spread in the U.S.
- Less attracted to humans: compared with native ticks (blacklegged, lone star, American dog tick), the CDC notes it appears less attracted to humans.
- Found more on animals: it can still be found on animals, so pets and livestock exposure matters.
Practical advice: if you find an unfamiliar tick, do not guess. Take a clear photo, save the tick in a sealed container, and use public health resources or a professional to identify it.
Where Ticks Hide on Long Island (and Why “Nice Yards” Still Get Ticks)
Ticks thrive where they can stay cool, shaded, and humid. That is why even manicured properties can still have tick activity, especially where the lawn meets natural cover. Long Island does not need messy yards to produce ticks. It needs edges.
- Wooded edges and property lines: the number one tick highway into the yard.
- Leaf litter under shrubs, hedges, and trees.
- Ornamental plant beds and groundcover: thick, shaded pockets.
- Stone walls, brush piles, and wood stacks: also attract rodents.
- Trail-side vegetation: ticks quest on the tips of grass and brush and grab passing hosts.
Why Suffolk County Tick Risk Gets So Much Attention
Suffolk County maintains tick education and surveillance efforts and calls out multiple diseases of concern, including Lyme disease, babesiosis, ehrlichiosis, and Powassan virus. The county also describes a tick surveillance program collecting ticks across townships and analyzing them for pathogens.
The practical takeaway: this is a known, ongoing public health focus, not a passing worry. Nassau County residents should not tune out either. The same edges, hosts, and habitat patterns run across the island.
How Ticks Find Hosts: Questing Behavior
Ticks locate hosts through a behavior called questing: they climb vegetation and extend their front legs to latch onto people or pets brushing by. This is one reason you can pick up ticks on quick walks. You do not need to go off-trail. If your legs brush tall grass at the edge, you are in the quest zone.
Long Island tip: stay centered on trails, avoid brushing tall grass and brush, and always do a tick check after outdoor time.
How Ticks Spread Disease
Ticks transmit pathogens during feeding. Some illnesses are more likely the longer a tick remains attached, which is why quick detection and removal matters. New York health authorities provide tick prevention and removal guidance statewide, including safe removal steps and when to seek medical advice.
Key point: the best time to act is the moment you come inside. Quick tick checks on kids and pets can prevent a long attachment time.
Preventing Ticks in the Yard: The Long Island Checklist
Yard prevention works because it changes the conditions ticks rely on: shade, humidity, shelter, and wildlife routes. The goal is not to erase nature. It is to make your high-use zones less tick-friendly.
Long Island yard checklist
- Remove leaf litter, especially along fences, woods lines, and under shrubs.
- Clear tall grasses and brush around homes and at the edge of lawns.
- Create a 3-foot barrier of wood chips or gravel between lawn and wooded areas to reduce migration into play spaces.
- Mow frequently during peak season.
- Stack wood neatly and keep it dry (discourages rodents).
- Keep patios, decks, and play sets away from yard edges and dense landscaping.
- Discourage deer and other wildlife with fencing where appropriate.
- Remove old furniture, debris, and clutter. Ticks and rodents love hidden, undisturbed spots.
Tick Bite Prevention for Families & Pets
Yard work is powerful, and simple habits help too. Build a routine: quick checks after woods-edge activities, gardening, hiking, and dog walks.
- Do tick checks on kids and pets after outdoor activity, especially near edges and brush.
- Use veterinarian-approved prevention products for pets (ask your vet what fits).
- Wear light-colored clothing on trails so ticks are easier to spot.
- Keep outdoor clothing contained after woods-edge activity instead of tossing it on the couch.
- Shower after heavy outdoor days; a hot dryer cycle kills ticks on clothing.
What to Do If You Find a Tick on You or Your Pet
If you find a tick, do not panic. The goal is safe removal and smart monitoring:
- Use fine-tipped tweezers and grasp the tick close to the skin.
- Pull upward with steady pressure. Do not twist or jerk.
- Wash the bite area and hands with soap and water or rubbing alcohol.
- Save the tick in a sealed container in case you want help identifying it later.
- Monitor for symptoms and contact a healthcare professional if you develop fever, rash, unusual fatigue, or joint pain.
- For pets, call your veterinarian if your pet becomes lethargic, feverish, limps, or seems off.

Laurie’s field note: Most of the tick calls I hear about follow the same pattern: a clean lawn that backs right up to a wild edge, and a family that never thought about the first ten feet of that edge. The fix is usually not the lawn. It is the leaf line under the hedge, the brush against the fence, and the shady corner by the shed. Handle those three spots and the whole yard usually calms down.
When to Call a Doctor or Veterinarian
Most tick bites do not automatically mean illness, but it is smart to be cautious. If you develop symptoms after a tick bite such as fever, rash, severe headache, unusual fatigue, or joint aches, contact a healthcare professional. If you are concerned, do not guess. Get medical guidance.
For pets: if your dog or cat becomes lethargic, feverish, limps, refuses food, or seems “off” after tick exposure, call your veterinarian. Early veterinary care can matter. Do not rely on home remedies to prevent tick-borne illness after a bite.
Long Island Tick Prevention: The 3-Layer Approach
The most reliable tick plan is layered. One layer helps. Three layers change your season.
| Layer | What it is | Examples |
|---|---|---|
| 1. Personal protection | Reduce bites during outdoor activity | Protective clothing, repellent, stay centered on trails, nightly tick checks |
| 2. Pet protection | Reduce ticks on dogs and cats and catch ticks early | Veterinarian-recommended preventatives, routine checks after walks |
| 3. Yard protection | Reduce tick habitat and contact zones around the home | Leaf litter cleanup, brush trimming, 3-foot barrier, targeted treatments in hot zones |

FAQ: Ticks on Long Island
What ticks are most common on Long Island?
The big three you will hear about most are blacklegged (deer) ticks, American dog ticks, and lone star ticks. Agencies also monitor the Asian longhorned tick in New York.
Why are deer ticks such a big deal on Long Island?
Deer ticks are strongly associated with Lyme disease in New York, and Suffolk County also lists anaplasmosis, babesiosis, Borrelia miyamotoi disease, and Powassan virus disease as concerns tied to blacklegged ticks. Nymph deer ticks are very small, making them easier to miss.
What is the Asian longhorned tick, and should I worry?
It is an invasive tick detected in New York that agencies continue to monitor. The CDC notes it appears less attracted to humans than native ticks like blacklegged, lone star, and American dog ticks, but it can be found on animals. If you find an unfamiliar tick, save it and get a professional identification rather than guessing.
What is “questing”?
Questing is how ticks find hosts: they climb vegetation, grip with their back legs, and extend their front legs to grab a passing animal or person. Both the CDC and Rutgers describe this behavior. Staying centered on trails keeps you out of the main quest zone.
Where should I focus yard prevention first?
Start with the edges: leaf litter, brushy borders, fence lines, under shrubs, and woods-to-lawn transitions. That is where ticks most often enter living-space yards. The Long Island checklist above walks through it in order.
Are ticks active in winter on Long Island?
Adult blacklegged ticks can be active during winter warm-ups whenever temperatures climb above freezing. Risk is lower than the spring and summer peak, but it is not zero. A mild January day can still mean tick exposure on a dog walk.
What should I do if I find a tick?
Remove it with fine-tipped tweezers using steady upward pressure, clean the area, save the tick in a sealed container, and monitor for symptoms. See your healthcare provider or veterinarian if symptoms develop. Our full tick-bite guide walks through every step.
When should I call a doctor after a tick bite?
If you develop fever, rash, severe headache, unusual fatigue, or joint pain after a tick bite, contact a healthcare professional. New York health authorities provide tick prevention and removal guidance statewide, including when to seek medical advice. Do not wait on a rash: not every tick-borne illness starts with one.
Does Bite Back service Long Island?
Not right now. We currently serve New Jersey and Staten Island, NY. This guide is here because Long Island families deserve straight answers too, and the prevention steps work no matter who does the treating. If you are in our service area, get your free yard assessment or call 732-333-3379.
How do I protect my dog or cat from ticks?
Ask your veterinarian about tick preventatives that fit your pet, do a tick check after every walk (especially ears, paws, and belly), and keep bedding areas clean. For the brown dog tick note in our NJ guide: repeated indoor tick sightings usually mean an infestation response with your vet, not more yard cleanup.
The Takeaway: Know the Tick, Work the Edges
Long Island’s tick pressure is real, but it is not random. Ticks cluster where shade, humidity, and hosts overlap, which means the edges of your property matter far more than the middle of your lawn. Identify the tick, target its favorite zones, and layer personal protection, pet protection, and yard work through the season.
If you are in New Jersey or on Staten Island and want help building a yard plan that actually reduces tick exposure, Bite Back is here. We focus on hot-zone targeting, prevention-first education, and an all-natural essential-oil approach designed to help families and pets enjoy their yards again.
