Following on from the mosquito repellent question, I would like to ask about another insect which for me is much harder to deal with, sand flies.
Answering a recent question about Honduras brought back vivid memories of being forced to leave a Garifuna village due to our inability to prevent sand flies from attacking us, or to make it bearable in any way. Anything we had with us for dealing with mosquitoes seemed to be useless.
So what does work to keep sand flies away, is it DEET or does something work better for these critters? And if you do get bitten what should you do?
I'm also specifically interested in home remedies. If you didn't pack some modern western chemical and find yourself under siege in a remote location what kind of things do poor local people use to prevent or relieve sand fly bites?
