Bugs BeGone is a DEET-free natural insect repellent, comprised of six different essential oils whose aromas, so pleasing and attractive to humans, keep the bugs away. The oils are combined in a synergistic way to magnify their effectiveness and then blended into a base of water, aloe vera, and polysorbate. The main essential oil is Eucalyptus Citriodora, or Lemon Eucalyptus, which has a fresh, sweet, lemon-like fragrance.
