As for bug spray, the only time I allow it for my own children is camping because there are so many bugs that within moments they can be covered from head to toe. This is an exception and really only means it is used a couple times a year on my own children so minimizes their contact with the chemicals. There are far more effective ways to repel bugs by consuming certain foods that I find effective...garlic for example when consumed means the bugs can not smell your blood and is highly toxic and poisonous to them.
