What are the common ticks of the Northeast?


Ticks are actually arachnids (the 8-legged class that includes spiders) and are found around the world. These are some of the common ticks in the US:

  • Blacklegged tick/Deer tick (Ixodes Scapularis)
  • American dog tick (Dermacentor variabilis)
  • Lone star tick (Amblyomma americanum)
Ticks have four stages in their life cycle - the adults are tiny, but the larva and nymphs are even smaller. For example, these are the estimated sizes at each stage:
  • Eggs
  • Larvae (0.7 - 0.8 m)
  • Nymphs (1-2 mm)
  • Adults ~6 mm)
