My family and I are happily leaving for St. John this Tuesday! I was wondering if we will need the Deep Woods Off with the 25% deet as opposed to the Family Off that is like 7%. I ask because when we were in Costa Rica last year, the bugs would laugh at 7%, we sprayed liberally with Deep Woods, but still wound up with some bites. That is the true rain forest, granted. I have some of both, but am trying to decide if I need to buy more of the Deep Woods.
