简单说就是用沾了洗涤剂的棉球把tick捂住，它就自己下来了。
Apply a glob of liquid soap to a cotton ball. Cover the tick with the soap-soaked
cotton ball and swab it for a few seconds (15-20), the tick will come out on its
own and be stuck to the cotton ball when you lift it away. This technique has
worked every time and its much less traumatic for the patient. Unless someone
is allergic to soap, this would not be damaging in any way.
