ChinaDoll, Go to Walmart's and buy Watkins bug replellent. Its a creme, not greasy, and after 3 trips to Roatan with many idfferent people, we all agreed the Watkins worked best. The only time I got any bites is when I forgot to put it on.
We have also used Cactus juice, Muskoil, Deep Woods Off, and Regular Off. Watkins still comes out on top.
Watkins is just DEET. Nothing special.
