You don’t have to be an outdoor adventurer to encounter a tick. In fact, people can encounter ticks where they live, work, learn and play, making it difficult to know exactly where the tick came from. Any time you step off the pavement, you could possibly encounter a blacklegged (deer) tick. Even if you don’t, lone star ticks you could be present in parking lots and board walks. Groundcovers such as pachysandra might contain blacklegged (deer) ticks. And don't forget that your pet can bring any of these ticks into your home.

Ticks are blood-feeding ectoparasites that quest for hosts in preferred environments. The three main tick species have different habitat preferences and tolerances:

  • The blacklegged tick, also known as the deer tick, requires high humidity or moisture to survive. Therefore, this tick is most often found in the forest and at the forest edge where tree cover, dense vegetation, and leaf litter provide a moist environment.
  • The lone star tick is able to survive in a wide range of habitats from the shade of the forest to the sun of a lawn.
  • The American dog tick can survive in warm, dry locations such as roadsides, trails and lawns.
  • Asian longhorned ticks have been associated with pastures, but have also been found in a wide range of habitats.
