Do not use alcohol
Some people immediately grab a bottle of alcohol as soon as they detect a tick. The idea behind it is not really surprising, because the alcohol numbs the animal. However, it is a bad idea to use alcohol when removing a tick. The tick then vomits its stomach contents on your skin. That is something you want to avoid.
It is best to remove the tick with special tweezers. Grasp the bug with the tweezers as close to the skin as possible so that it is least likely to break off, with its head in the skin. First, twist the tweezers to the left or right to release the tick, then pull it out. If a piece of its head remains in the skin, don’t worry, it’s harmless. It comes out on its own, just like a splinter that cannot be grasped with tweezers.
