Don’t use salt, fire or lighters on leeches. The leech is attached, gave you a light anesthetic, punched a hole through your skin to a blood vessel and now drinking the blood by sucking through the hole. When you use salt or fire in the leech, you’re shocking it with extreme pain which makes it vomit through the hole it’s sucking on … basically puking into your body. This has the danger of causing an infection or even a reaction to whatever was in the leech stuff that went back into your body.

Carefully and slowly pinching and nudging them is the safest way to get them off.
