Leeches are a problem - If you have been trekking in Nepal during the monsoon, then you soon learn about leeches. They are not harmful, but they sure make a bloody mess of your socks and boots. The Leeches wait on the grass and the leaves of the brush until you walk by, then they fall onto your boots. They crawl up to your socks and burrow their way through your sock into your leg. You don't even notice them, until they are thick with your blood and then have spilled most of it all over your socks and boots.
The simple solution is a durable brushed cotton leech-proof sock that is worn over your normal sock and inside your boot. You don't even notice it. The leeches cannot penetrate it, and it is difficult for them to climb up. The sock is comfortable to wear, because it is so thin. It is secured by two elastic nylon cords above your knee and along your calf, so that it won't fall down. The Anti-leech sock can be worn with pants or with shorts. It is rugged enough to be worn every day for a two week expedition, and it is resistant to tears from brush or thorns. If you wash it, it is light-weight enough to dry quickly. The Anti-leech sock comes in one size which will fit comfortably over socks on big or small feet. The sock collapses comfortably in the boot around your sock, so it will not interfere with the fit of your boot.

Developed and tested in the jungles of Southeast Asia by scientists and wildlife conservationists in the field. I have used this sock during Tiger camera-trapping excursions in the Khao Yai National Park in Eastern Thailand and in the lower Himalaya of Nepal. There are many leeches there, and this sock works extremely well. I did learn one additional secret from the Thais, Cambodians and Burmese that I was working with. They all wore various versions of this Anti-Leech Sock, but they also took tobacco leaves with them in a plastic bag. They would mix the tobacco with water, and let the tobacco seep into the water. Then they would squeeze this caramel-colored water from the bag and rub it onto the anti-leech socks. This technique was extremely effective against leeches. The leeches were strongly repelled by the tobacco residue on the sock, and they were unable to bite through nor climb up the sock. They just fell off.

If you are planning any trips into the Jungles of Asia or South America, then don't forget these Anti-Leech socks. They are extremely good value for money and they are well made. They will last you many expeditions. Don't forget the tobacco! more information on leech bites.

Assistant Professor Sara Robinson from Oregon State University in Peru. I purchased your leach socks right before a trek to the Amazon rainforest in Peru (an area near Madre de Dios). Peru has minor numbers of terrestrial leaches, but has an incredible number of biting ants and huge mosquitos. Having done work in Thailand, where leach socks are a necessity, I brought this pair along to see how they did. I research fungi and their interactions on wood, so I am often crawling around on the forest floor, getting all kinds of nasty bites. I think you can safely add to your list of benefits that even thought I encountered Tangarana ants, fire ants, mosquitos the size of footballs, and other fun biting things, I got ZERO bites on areas covered by the socks. I suspect my Peruvian field guides, all of whom had to make at least one dash to a shower to rinse of ants, will be purchasing their own soon. Thanks for making such a great product! (May 2013)
