When a leech bites you, it sticks to your skin using small suckers. It bites with its mouth and starts drinking your blood. You usually don’t feel anything because the leech puts in a chemical that numbs the area and stops your blood from clotting. That’s why it might keep bleeding for a while after the leech is gone.
What to do if a leech bites you:
Stay calm – leeches aren’t dangerous in most cases.
Don’t pull it off quickly, or part of it might stay in your skin.
Gently slide it off using your fingernail, a stick, or something flat like a card.
Wash the bite with clean water and soap.
Put on antiseptic to stop germs from getting in.
You can cover it with a bandage if it keeps bleeding.
After the bite, the area might itch, swell, or bleed a little – that’s normal. But if it gets red, very swollen, painful, or has pus, it might be infected, and you should see a doctor.
