In my Chemistry class, we covered insecticides. Yes, the 100% DEET stuff is what to go for. Or you can try to find 150 or 200% superconcentrated stuff, but I have never seen those. My chemistry teacher recommends Woodsman or Benz. OTOH throwing in a good mosiquito net would be very helpful, but I'm one to talk. <img src="images/graemlins/grin.gif" alt="" />
