Enjoying the great outdoors also means sharing it with other creatures — including biting insects. The Entomologist from Heretic Parfum is an EPA-Compliant, 100% natural spray comprised of a signature blend of essential oils known to be high in phyto-chemicals that deter biting insects. It's free of DEET and other toxins used in most insect repellent products, and has an aromatherapeutic scent that is both invigorating and purifying.
