Quick Facts About Ticks

  • Ticks are not insects. They are parasitic arachnids (related to spiders and scorpions) with eight legs and no antennae. 
  • Ticks feed on blood and require it to survive. Many ticks will bite and feed on humans, dogs, deer, mice, and other wildlife.
  • Tick saliva contains a natural anesthetic, so people often do not feel or notice the initial bite—this is especially dangerous as ticks are known to carry dangerous pathogens. 
  • They are carriers of Lyme disease, Anaplasmosis, and Babesiosis, and may also be co-infected, meaning a single bite could expose you to two or more different pathogens simultaneously.
  • Ticks feed on blood until they are full and then drop off the skin, but this process can take several days. The longer a tick feeds on a person or animal, the more likely it is to transmit diseases like Lyme disease

Habitat, Diet, Life Cycle, and Behaviors

Where Do Ticks Live?

Ticks love moist, shady environments where lawn meets woodland, thick shrubbery overgrowth, tall grass, and leaf piles. Stone walls, brush piles, and dense ground cover are all prime habitats for ticks.

Suburban neighborhoods near parks and reserves, including areas in Westchester County, Bergen County, and Fairfield County, can harbor ticks. On Long Island and in parts of New Jersey, ticks are commonly found in landscaped yards where deer or rodents frequently pass through.

Ticks don’t jump or fly. Instead, they wait on grass, leaves, or shrubs and latch onto a person or animal as it brushes past. Pets can bring them indoors after a walk, while people can carry them on clothing, shoes, or outdoor gear.

What Do Ticks Eat?

Ticks feed exclusively on blood by attaching to a host’s skin. In the Northeast, they may feed on mice, chipmunks, birds, squirrels, rabbits, deer, dogs, cats, and people.

Before feeding, ticks are thin and flat. Once attached to a host, they begin to siphon blood—a process that typically takes three to nine days but can last up to 12. As they feed, they swell immensely; for example, female ticks can increase their volume by up to 100-fold, growing from the size of a sesame or poppy seed to that of a coffee bean or small grape.

In contrast, male ticks do not expand much because most of their back is covered by a hard shield called a scutum.

Tick Life Cycle

Ticks complete a complex, four-stage development cycle: egg, larva, nymph, and adult. This entire process typically spans two years, though warmer weather conditions can significantly speed this up. Crucially, ticks are parasites and must consume a blood meal from a host to pass from one life stage to the next.

  • Eggs can take anywhere from three weeks to two months to hatch 
  • Larvae are immediately ready to feed; they will attach to a host and feed until they become engorged before dropping off and molting into the nymph stage 
  • Nymphs require another blood meal to continue their development, eventually molting into adults
  • Adult ticks typically feed one final time; female adults then lay thousands of eggs before dying, completing the life cycle

Behaviors

Ticks do not jump, fly, or drop from trees. Instead, they wait on the tips of grass, shrubs, leaf litter, and other low vegetation—a behavior called questing. When a person, dog, deer, or other animal brushes against the vegetation, the tick grabs on with its front legs.

They generally suck blood around the ankles, armpits, underarms, ears, or scalp. You may find the tick burrowed into your skin, or you may see a swollen, red welt. This welt may itch or hurt. Ticks may also latch onto pets around the eyes, paws, shoulder blades, lower legs, noses, or ears.

After a week, some tick bites may develop a “bullseye” rash with an outer ring. This can sometimes be a sign of Lyme disease, though not all ticks carry the bacterium that causes Lyme disease.

Dangers and Health Risks of Ticks to Humans

When a tick bites, it inserts its mouthparts into the skin and secretes a cement-like substance to stay attached. It then feeds slowly on blood. During this time, disease-causing bacteria can pass from the tick into the host.

In our region, deer ticks, American dog ticks, and lone star ticks all bite humans and pets. Deer ticks are the main concern because they can carry Lyme disease. Symptoms include a rash, headache, nausea, swollen lymph nodes, weakness, muscle or joint pain, and fever or chills. Some people develop a bullseye-shaped rash, but many don’t show any signs.

Moreover, Rocky Mountain Spotted Fever (RMSF), transmitted by the American dog tick, can be life-threatening, with symptoms including respiratory issues and abdominal pain. These adverse effects make ticks a source of stress for families, pet owners, and property managers.

Types of Ticks

Ticks are small (approximately ⅛ inches to ¼ inches) parasitic arachnids that feed on “blood meals” to survive. Depending on the tick species, they’ll latch onto animals, such as dogs, deer, mice, fowl, or onto humans.

The New York tri-state region is home to several tick species, including the Asian longhorn tick and the Gulf Coast tick. However, the three most problematic species are: blacklegged (deer) ticks, American dog ticks, and lone star ticks.

Blacklegged Ticks (Deer Ticks)

Deer ticks are tiny, particularly at the nymph stage, and often no bigger than a poppy seed. They have dark legs, a dark shield near the head, and a lighter brown body. Because they’re so small, the host often doesn’t realize they’ve been bitten. Deer ticks are the primary carriers of Lyme disease.

American Dog Ticks

American dog ticks are larger and easier to see. They have a mottled brown-and-white pattern on their backs and a hard, shield-like body. When engorged, they can look swollen and grayish. People often panic after finding an engorged American dog tick, which can cause Tularemia and RMSF.

Lone Star Ticks

Lone star ticks are named for the white dot found on the back of adult females. They have longer mouthparts than other ticks, which can make bites more irritating. These ticks are aggressive and actively seek hosts rather than passively waiting. A bite from this tick can trigger a red meat allergy that can lead to anaphylaxis.

How To Get Rid of Ticks

 

Reasonable tick control starts with everyday habits. Simple maintenance and hygiene practices go a long way toward reducing exposure, especially in communal yards, parks, and outdoor spaces that see regular use. 

How to minimize the risk of tick bites:

  • Wear protective, light-colored clothing to reduce exposed skin and make ticks easier to spot before they attach
  • Use repellents such as DEET or permethrin to discourage ticks from latching onto your skin during outdoor activity
  • Avoid tall grass and overgrown areas where ticks wait along trail edges, fence lines, and yard borders
  • Maintain lawns and remove debris by mowing regularly and clearing leaf litter, brush, and clutter that holds moisture
  • Combine routine upkeep with professional tick treatment to reduce active populations and prevent ticks from returning season after season

Frequently Asked Questions

In the tri-state Area, ticks are most often found in shady, humid outdoor spaces like wooded areas, woodland edges, tall grass, and brush. However, they are not limited to remote hiking trails and can also turn up in suburban yards, city parks, dog-walking areas, and around woodpiles or bird feeders that attract wildlife.

Ticks hide in vegetation like tall grass and wait for humans or animals to brush past before attaching themselves. They use specialized mouthparts to anchor themselves in the skin while they feed on blood.

Tick season in the New York tri-state region generally ramps up in early spring and runs through fall, but ticks don’t follow calendars; they follow temperatures. When conditions are mild, ticks stay active. In places like the Hudson Valley, Long Island, and coastal Connecticut, warmer weather can extend the season well beyond what you might expect.

No, not every tick carries disease-causing germs, and not every bite from an infected tick results in illness. The risk depends on the tick species, whether it carries a pathogen, the location of the bite, and how long it was attached—so it is always best to take tick bites seriously.
