D.E.R stands for Recurrent Summer Dermatitis (Dermatite Estiva Recidivante)- commonly known as Sweet Itch. Bites from blood-sucking insects, especially the female Culicoides (small midge) cause skin lesions and severe itching.
An effective insect repellent and a very good coat conditioner as well. Lavender Water, Geranium Essential Oil, and Neem Essential Oils are rich extracts from plants known to repel insects. Lavender and Geranium Oils in particular exude an essence that is very pleasant to humans, but highly repellent to insects. Historically, lavender bouquets were placed at special points of houses to keep out flies and mosquitoes. Geraniums were placed on balconies and windowsills to repel all annoying flying insects. Formulations made of neem oil also find wide usage as a biopesticide for organic farming, as it repels a wide variety of pests including biting flies that plague horses.*
