As above Jungle Forumla, anything with 50% DEET (100% seems a little OTT, especially when I've seen 50% eat the rubber seals on my kayak cag!) or the Avon stuff (I use it all the time when climbing and its gentle on your skin [leaves you smelling like a puff though]). I use Life Systems 50 now and never have any problems.
