Well, since I am now suffering from a rash due to poison ivy...I will be sure to put on my jungle juice each and every time I go anywhere near the sand at dusk. I am really sensitive to bites and had a horrible trip one August when I had to have at least 30 bites on each ankle. I do not want to be itching like I am right now on vacation.
Since then, I never go near the beach without stuff on. Our last trip in October, hubby got bit up on the deck by the swim-up bar. I was lucky and had gone back to the room to get ready.
We take Jungle Juice--we buy our stuff at REI or the camping section of any sports store (walmart might even have it in their camping section). It has a really high concentration of deet--you use just a few drops and spread it around. I don't smell the best but I am not scratching either!
I do think it all depends if the bugs like you...and they obviously like me!
