The other day someone posted something interesting about leeches. Apparently you can use anti-mosquito spray to make them detach from the skin in minutes.

Saw that comment and I’m pretty sure that it is a bad idea since the article explicitly mentioned that stressing the leeches causes them to “vomit blood back into your bloodstream” and introduces a risk of bacterial infections. The advice was to use a credit card to quickly break the suction seal and force the leech to detach.

We've used pocket hand sanitiser to make Leeches to detach.
