Are the leeches in Sinharaja Forest really that bad?

Question

I want to do a rainforest trek, but I am terrified of leeches. Are they unavoidable in Sinharaja?

Sunil Perera · Accepted Answer

Yes, they are unavoidable, especially if it has rained recently. But they are completely harmless. Your guide will provide you with "leech socks" (thick cotton bags that go over your pants and shoes) and will spray your shoes with a salt-water mixture. You will be fine.

Leeches in Sinharaja are real and common, but they are manageable with the right preparation — they are not a reason to skip one of the world's most extraordinary rainforests.
The honest truth is that leeches are essentially unavoidable on the forest floor, especially during and after rain, or in the wet season (roughly May–September and November–January). They are tiny, fast, and surprisingly good at finding gaps in your clothing. Most people pick up several during a half-day trek. However, they are not dangerous — Sri Lankan forest leeches are not disease vectors, their bite is painless (you usually don't feel it), and the main annoyance is a small amount of bleeding that can last a while due to the anticoagulant they inject.
Here is what actually works to protect yourself:
Wear long socks and tuck your trousers into them tightly. Dedicated "leech socks" (thick cotton or purpose-made ones) are sold near the Sinharaja entrance and are worth buying for a few hundred LKR.Apply salt, tobacco, or a DEET-based repellent to your socks and trouser cuffs before entering — guides swear by this and it genuinely reduces attachment.Check yourself every 20–30 minutes on the trail, especially ankles, behind the knees, and waistband.Carry salt in a small container — sprinkling it on an attached leech makes it release immediately without leaving the head embedded (avoid burning or pulling, which can cause infection).
Your guide is your best asset here. Sinharaja requires an official guide anyway, and they are expert leech-spotters who will help you check and remove them calmly. Most experienced trekkers come out of Sinharaja with a few bites and a great story, and the birds, purple-faced langurs, and ancient trees make it completely worth it. Go in the dry season (February–April or August) if you want the least leech activity, though even then expect some.

Okay, the leech socks make me feel a lot better. I will brave it. The biodiversity sounds too good to miss.

Another trick is to rub Ayurvedic "Siddhalepa" balm on your ankles. They hate the smell of it and drop right off.

Devin Kumar · Answer

I wore the leech socks and not a single one got on my skin. Just don't stand still in the wet leaf litter for too long!
