I have noticed and read that being clean (no sweat) helps. Some 3rd world people try to bath 3 times a day for this reason. Others cake grease and/or clay on themselves as a barrier against these critters. Bay leaves (Umbellularia Californica) were used to repel fleas and lice. Some use them to keep bugs out of dried food like grains and beans. But they seem to do nothing to mosquitoes and the like.
