leech socks

I'm a bit concerned about the whole leech thing. I know I'm obsessed, but yeuch, ergh etc. can't really bear the thought of them. Spent some time googling leech repellent whilst the kids had a DVD. The only effective thing is to purchase some leech socks (not socks for leeches, which would be very small and slimy, but socks to stop leeches getting their evil little fangs into your lower limbs), apparently, so I might have to take a trip to Thamel this weekend...
