If you would like to make your own bug repellent but not have to spray yourself or the kids with oils which can get on nice clothes why not try these lotion bars from Homemademommy. I love the shapes she used and that you can carry them in your purse in a tin or box and not have to worry about them spilling all over everything like you do the spray.
