I use adult formula Off, but not on the skin. I'll spray a little on my hand or cloth, then wipe on hat, clothing, etc. It seems to help. We lived in the forest at our old location so the mosquitoes were like bloody hummingbirds! Still got some bites, but greatly reduced. Something else that can be done is for the kids to hold a cloth or something over their face. Just spray a fine mist in the air above them and let it fall over them. It just takes a tiny amount...doesn't have to be slathered. When I'm in Central America or Caribbean where mozzies are AWFUL and horribly aggressive, I'll spray in in the air and walk through (like with perfume)...frontward s and backwards. I rarely get bitten on vacay, so must work
