Jolt, I know you are probably trying to go the natural way, but lemon eucalyptus probably is not going to cut it. There is another new chemical spray out. The main ingredient begins with a p, but I can't remember the name. My friend who can't use Deet, uses it. Why don't you check that out? Otherwise, I would go with the regular Deet stuff, especially with the amount of rain we have been having.
