Abstract: A natural repellent is based upon the use of pine oil as the sole active ingredient, in combination with inert ingredients (such as denatured ethanol or ethyl alcohol) and a proper conveying medium. The pine oil may take the form of a refined oil of pine, aromatic compounds thereof, or any derivative or monoterpene compound thereof. In particular, the repellent is based upon the use of 0.01-50% refined pine oil (by volume) and is particularly well-suited for use as a tick repellent, as well as for controlling the presence of other biting/non-biting insects and arachnids.
