No updates that I am aware of. Its hard to tell if the products work in my opinion because as was mentioned above a wind off the ocean pretty much eliminates the bugs that way. We tried some products with high levels of deet and also the skin so soft, but since you can't see the bugs to tell if they are around it is just a guess that the repellent or skin so soft oil is working. My daughter has used California Baby products on our grandchildren that are more friendly than deet products if you are worried about putting repellant on kids. We have been to Vero about 8 times over the years and only had a problem twice.
