I was recently researching the use of DEET insect repellent for campers. It sounds like there is some discrepency about whether or not it will be harmful to children. Does anyone have insight about the use of DEET on children and how harmful it can be, if at all. We are located in WA state and have a fair amount of mosquitos, but nothing that seems to be health threatening (such as the severity of insects in other regions of the US and New Zealand) - only an annoyance. Any thoughts?
