So I did a hike in a forest infested with leeches. I ended up with quite a few leech bites (around 20). But, at the same time, another hiker got just one bite!
We both were wearing similar shoes, socks and trek suits. Hence, in theory we were pretty similar. Also, we did clean up the shoes/socks often. Yet, the number of leeches on me was way more than the one on the other trekker.
So what is it that attracts the leeches? Do they have a preference of going for a particular set of people? (Maybe driven by smell?).
