Blacklegged Tick: Identification, Damage, Prevention & Control

What Are Blacklegged Ticks?

The Blacklegged Tick, commonly known as the deer tick, is a small parasitic tick that feeds on the blood of animals and humans. It is widely known for its ability to transmit certain diseases, including Lyme Disease.

Adult blacklegged ticks are very small, measuring about 3 to 5 mm in length before feeding. They have a dark brown to black body, with females showing a reddish-orange area behind the head. After feeding, their bodies can become significantly larger.

These ticks are commonly found in wooded areas, tall grass, shrubs, and leaf litter, where they wait for animals or humans to pass by.

Blacklegged Tick Life Cycle and Development

These ticks have a two-year life cycle: egg, larva, nymph, and adult. Larvae and nymphs feed on small mammals and birds, while adults target larger hosts like deer, pets, and humans. Nymphs are key in spreading tick-borne diseases because they are tiny and hard to detect. Ticks don’t jump or fly; they “quest” by clinging to grass or shrubs and attaching to passing hosts. Knowing their life cycle and behavior helps prevent tick bites and reduces the risk of Lyme disease and other tick-related illnesses.

Where Blacklegged Ticks Live

These pests thrive in moist, shaded environments where they can avoid drying out. Common habitats include:

  • Forests and wooded areas
  • Tall grass and dense vegetation
  • Leaf litter and brush piles
  • Shrubs and forest edges
  • Gardens near wooded environments


Around residential properties, ticks may be found in:

  • Backyards with dense vegetation
  • Areas with fallen leaves
  • Near stone walls or wood piles
  • Along property edges near forests


Properties that attract wildlife such as deer, rodents, or birds may also have higher tick activity.


Are Blacklegged Ticks Dangerous?

Blacklegged ticks are a major public health concern because they can transmit diseases to humans and pets, most notably Lyme disease. Symptoms of Lyme disease include fever, fatigue, headaches, joint pain, and skin rashes. Since ticks usually need to remain attached for several hours to transmit disease, early detection and removal are crucial. Pets can also be affected by tick bites and may bring ticks into homes, increasing the risk of exposure.
