Leech bite: Treatment, Infection, Cure & Mark Prevention

Leeches are mostly found in the damp area. They love living in a wet place. They are mostly found in the tropical and subtropical climate. So, chances are higher that leeches would be found in the South-East Asian countries where there is a rainy season, often called as the monsoon in India.  Thus, the monsoon is a big time when you would find a lot of leeches on every square foot in the forest.

Where are leeches found?

  • Leeches are found in the dump areas
  • They could be hiding underground or on the twigs or leaves. They could simply be found anywhere in the forest
  • Leeches are mostly found in the low-land area with thick forests somewhere around up to 3000 feet
  • The higher you trek, the lower their density would get with altitude
  • Thus, in South India rain forests, leeches are mostly found in the forests with thick tree covers. Once you trek and reach open grasslands after 3000 feet, you would see that the number of leeches has gone down drastically.
  • If you happen to go on any western ghats treks in the monsoon, you can find a lot of leeches. Some of the treks are Kumara Parvatha, Kodchadri, Tadiandamol, Kudremukh, Bandaje arbi etc.

How do leech bites happen?

  • There is no rule on the trek or hiking inside a forest that the person walking in the front would get lesser leech bites. This would be true only if the person does not stop at all for others walking behind. Most of the times, the person walking at the front stops and waits for others which give more than ample time to leeches to crawl over.
  • Leeches are sensitive to vibrations and body heat.

  • Since they are sensitive to body heat, thus they would mostly prefer the body areas where body heat is usually higher like armpits, under the feet, belly etc. So cover these areas to avoid leech bites
  • Leeches in south India treks can suck blood from both sides. so be careful

Myths about leeches:

  • Leeches can jump. No, they can not.
  • They can grow when cut half. No chance
  • Any other stories: apply your brain pls

How to avoid leeches:

Avoidance or prevention is better than cure. Here are the tips on how to avoid leeches from sticking to your body.

  • Applying salt (during monsoon, salt easily gets washed away and moreover, this solution is effective only after the leech attack)
  • Make a mix of Coconut Oil and tobacco and apply to your body especially on lower and exposed areas like legs and arms.
  • You can also mix a mosquito repellant cream with tobacco and apply on the exposed part of your body. Leech does not like the smell of tobacco.
  • Wear leech socks or Trail-Gaiter (A thick cloth socks which won’t allow leeches to slip in through)

  • Keep walking and not to lean on any plants/ tree in the forest (The best for a leech to come into contact with you)
  • Do not stop to remove the leeches (By the time, you take out some, a few another would already be there on your socks)
  • Cover yourself properly 
  • You can also use Ladies Knee Length Stockings
  • Strong smell of Dettol also repels the leeches
  • or, the last resort is they would suck up blood; get fatter and roll down  themselves like a lazy fat insect

Leech bites Precaution:

  • Do not scratch that area. It will itch a lot but scratching would never allow new cells formation over the wound
  • Do not panic or scream, they are very week insects and leeches do not carry poison.
  • Due to anticoagulant, the leech bites would not allow stopping the bleeding. Better would be put a piece of paper over there and bleeding stops most of the times.

    I have heard that to stop bleeding of leech bite, a piece of cotton cloth should be burnt and the ashes should be applied to the wound. I have not got any scope to apply it so far. In October this this year, while visiting East Sikkim, I will be carrying a cotton cloth piece …. I will be waiting for a leech bite on any of our six-members… Only then I can prove whether this remedy is fruitful.

    Thank you and just wow for such comprehensive insight on avoiding and treating leech bites. I’m in wonderment of these tenacious creatures, but I just couldn’t overcome my fear of leeches whenever they made way to my legs. Because its such a personal phobia to me, I just wanted to jump in on an additional tip that helped me a lot during my last trip to Nepal Annapurna. Perhaps as an additional protection on top of any leech socks one would prepare so to keep them completely out.

    We were haunted by the horde of leeches while trekking towards ABC. Unfortunately it was during the monsoon season but fortunately my guide brought along and recommended a ‘barrier’ repellent called Leech Hound to us during our trek. It worked very well preventing leeches at our shoes like there’s an impenetrable shield. I’ve been looking for it on the internet since I returned. So far only found 2 sources from ebay and Amazon – https://www.ebay.com.au/itm/263810846962

    I’ve done much research to on leech protection. Just thrilled to know that there is a functional specialized product. I am glad I came across your blog to know about how other people deal with leech situations. Hopefully this helps another fellow adventurer.

      best solution for the leach bite infection will be..take a TT injection and apply FUBAC ointment so that itching will be reduced and infection will not spread..it will heal very soon.. injection helps a lot.

    While wading in a fresh water pond on Cape Cod, I was bitten by a leech between my toes a week ago. Redness, swelling and itching developed after a day. I consulted a doctor by phone and he prescribed Sulfamethoxazole Trime 800mg tablets twice a day for 7 days. Halfway through the course, the irritation is a little less. Eczema lotions, benadryl (an antihistamine) gel and tablets, and Bactine liquid with Lidocaine help to control the itching. If it does not substantially clear after 7 days of treatment, I’ll go back to the doctor.

    I went trekking today and unluckily got a leech bite.The bleeding won’t stop and the area where it bit is a bit swollen so what should I do? I’m really worried.

    • trekkerp Post author

      Apply the area with mild soap water. While sleeping put the legs up so that the blood pressure is lesser. if the blood still does not stop. See a doctor

    hi. i went to a camp last year (nearly 12 months). i was bitten by a type of leech which is smaller (can be found easily around Asia). it has swollen and has blood like blister, swollen and very itchy on that spot. i always scratch it and it is gotten worse. the skin is getting darker and always bleed as i l always scratch it. the spot becomes bigger. my concern is that, months later (till today), i have the same few spots which is getting bigger around my legs. i thought it was scabies but nothing happen when i treated it with anti-scabies. now i have a few around my legs. is it because of the leech bite or something else? and what should i do?

    Hello! Are there any places close to Bangalore (which can be accessed in a day’s trip) where I could find leeches? Most places that I know of are too far away to be covered in a single day.
    (I need the leeches for a project on animal behavior, that is why I am looking for them.)

  12. Koushik Chattopadhyay

    Hi, I was bitten by a leech about 10 months back. It occasionally itches and a small area around the bite had become quite stiff. A few days back, a blackish red blood oozed out. The lump has reduced since then. What treatment should I follow?

    Should I consult some doctor (if so, what specialization)? What are the long term effects of the leech bite?

  13. Koushik Chattopadhyay

    Hi, I got bit by a leech about 10 months ago. Occasionally it itches but only for a short period of time. A small area around the bite has become very stiff. A few days back, while itching blackish red blood oozed out. The lump has reduced a little after that.
    How should I cure it completely? Should I consult a doctor (if so, which specialization)? Is there any long term side effects?

    • trekkerp Post author

      Hi Koushik,

      Since it is a very old bite, I would suggest you consult a doctor (Skin specialist/ dermatologist). Yes, it has long term effects like eczema and darker skin on that area.

      Please do not scratch or itch until you see a doctor. Use moisturizer and keep it open until that time.

      Let me know the doctor’s advice

      Hi Lily,

      If you could explain your problem in little more detail, I think I can help you. Else please visit a doctor.

    Really a perfect post. Actually leech bite cannot be taken easy. Treatment post leech bite is very important. Infact without treatment it can lead to serious cellulitis and eczema after which the wound may become big and take even 6 months to heal. I believe its mandatory to leech socks especially if trekking in forests with leeches.
