The head of the leech is actually the sucker by which the leech attaches itself to your body for its sucking the blood task. So firstly you need to find out the sucker of the leech and even if there is one leech sticking on to you, do check for other leeches because there may be a probability that another leech may be clinging to you and you may be completely unaware.

  • Treating the wound

During a leech bite, an anticoagulant is injected inside the body by the leech which prevents the blood from forming a clot. When the leech is removed, there are chances that the affected area may bleed continuously as clots are not formed. So do not panic in such a case and instead focus on treating the wound to avoid any further Infection and cure the wound by applying a bandage at first. An open wound has more chances to catch infection so make sure that you bandage regularly until the wound heals and is covered at all times. You can also get an itching sensation during the process of healing of the wound but do not panic and stay calm.

  • Fill and drop

Leeches drop down and detach from the host’s body as soon as they are filled and fall on their own after an approximate of twenty minutes. So you can wait till this happens on its own so that the sucker part is not left inside when you try to pull the leech by yourself. From ancient times leeches have been used for treatment by the bloodletting process thus it is not something to be afraid of when you get a leech bite. So if you manage to gather courage for yourself, then you can wait till the leech drops by its own.

  • Avoid extraction of leech by other methods

There are other methods such as burning the leech, pouring salt on them, spraying repellents, etc. But it is advisable that you stay away from such methods because these methods will surely help you to remove the leech but in return, they can vomit on the wound which may increase the infection and cure may be a long process in such a case. So it is better that you use the fingernail method above all the other techniques of leech removal.

  • Find out the depth

Many times it happens that the leech burrows themselves in your body at greater depths especially when you are swimming in places where there is leech population nearby. In such a case it is quite probable that the leech may sting at places such as your ears, mouth, etc. So in such a case, you need to take help of somebody who can help you out to identify the sucker part of the leech and then remove the leech by the fingernail method. If you are not able to find out, then try to stay calm and wait till the leech drops by itself. If the leech happens to be in your mouth, then you can use alcohol for rinsing your mouth which will in turn help in detaching the leech from your mouth. Once you clean your mouth with alcohol, you need to spit it off and check if the leech has come out or not. If the leech has not yet left its place, then you need to gargle again and again till it leaves its grip and comes out. If alcohol is not available at that moment, then you can also use hydrogen peroxide in its place. Also, seek medical attention if this happens to be your case.

  • Leech puncture

If you happen to be in a place where you cannot seek medical attention nearby, then the next thing that you should do is to puncture the leech as soon as possible. If the leech happens to attach itself to your nostrils, then it may cause you breathing problems, so make sure that you puncture the leech and kill it at once. Once the leech is dead, remove its body and wash the affected area.
