Catch leeches can be stirred in the water with a net, because leeches are very sensitive to the movement of water, water frogs are very sensitive to the movement of water, and after the water moves, leeches will enter the water from the soil and grass, at this time you can catch them with a net.

2) You can also use vinegar, wine, salt water, e-liquid water or cool oil to apply it to the leech and the adsorption site to make it come out naturally.

3) Do not pull forcefully, otherwise the leech suction cup will break into the skin and cause infection.

It is only necessary to apply iodine to the wound to prevent infection.

It's okay. It's nothing, it's just a little red.
