Bug Protector Natural Mosquito Repellent is an all natural bug spray. The active ingredients are all plant based including Lemongrass Oil, Geranium Oil, Peppermint Oil, and Cinnamon Oil; because of this Bug Protector smells wonderful instead of a heavy chemical scent. In addition, Bug Protector really works. I live and work in places where the bugs can get very heavy. With Bug Protector I noticed a large decrease in the bugs that were bothering me. For application, I felt safe using this on my whole family, including my three year old. There was also no greasy or heavy residue from this spray. After being most of the day, I noticed that re-application was needed after a little more than two hours.
