This is something that actually is a pain in the Amazon, the itch mite
is easy to get in the jungle. We always recommend to our tourist to wear
swamp boots, long socks and before getting into a walk to put some
Jhonson oil on their legs.
There is this product that you must have it in you first aid kit, Crotamiton in lotion is really good for this kind of itching and will get rid off the itch mites.
