Remove the tick properly. Using sharp pointed tweezers, or specially made tick tweezers, grasp the tick as close to your skin as possible, as close to its embedded mouthparts as you can. If you squeeze the body or head, you risk compressing the guts and salivary glands and expelling even more organisms through their mouth into your body.
