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.
