Does anyone on here use them? I made an impromptu roller of mosquito repellent this evening for my husband. I used lemon, peppermint, tea tree, and lavender since those are oils I had on hand. It seemed to work well enough as my husband worked in the garden and he can't use commercial bug spray without getting sick from the fumes. I'm going to have to research recipes for a better recipe and get the stuff for it. Does anyone have any tried and true uses for oils or for homemade recipes for mosquito repellent?
