It's always better to be prepared when it comes to ticks.
Ticks can be annoying and dangerous.

The CDC does not endorse this method because the objective is to remove the tick as quickly as possible. Using tweezers is the quickest way to remove a tick, but if not done carefully, it can cause the head to stay under the skin.
