I actually just bought an all natural mosquito repellent this weekend because I have a hard time putting Deet on my 2 year old. So I went to the Mustard Seed (all organic store) and asked one of the ladies there. I ended up buying:
All Terrain: Kids Herbal Armor Insect Repellent (Deet Free Pump Spray)
I can not tell you at this point how well it works because I ended up not using it we had a constant fire to keep bugs away. But will be using it soon, I am sure. I will let you ladies know, but according to the ladies here and the self it is popular.
There is a website if you would like to look it up:
Hope this helps?
