FIRST AID Advice - How to Remove a Tick

Wood Tick Removal:

  • Use a pair of tweezers and grasp the wood tick close to the skin (on its head). See image.
  • Pull the wood tick straight upward without twisting or crushing it. Maintain a steady pressure until it releases its grip.
  • If tweezers aren't available, use fingers, a loop of thread around the jaws, or a needle between the jaws for traction.

Tiny Deer Tick Removal:

  • Needs to be scraped off with a knife blade or credit card edge.
  • Place tick in a sealed container (e.g., glass jar, zip lock plastic bag), in case your doctor wants to see it.

Note: Covering the tick with petroleum jelly, nail polish or rubbing alcohol doesn't work. Neither does touching the tick with a hot (like a match) or cold object.

Erythema Migrans Rash
Erythema Migrans Rash

The majority of cases of Lyme disease start with a bull's eye rash ("erythema chronicum migrans") at the site of the tick bite. The rash can occur days to weeks (typically 7-10 days) after a tick bite.

Treatment with antibiotics is indicated if this rash appears.

It is thought that Lyme Disease can be prevented if the tick is removed within 24 hours of attachment.
