METHOD AND MEANS FOR REPELLING ANIMALS

摘要

For repelling elk, hart, roe deer and similar animals from plantations, orchards, road sections etc. one or more natural or synthetic steroids of the type occurring on human skin or hair or in human sweat or urine are used. Also derivatives of these steroids obtainable by subjecting the steroids to air, moisture or micro-organisms may be used. The steroids are combined with a carrier into a repellent unit which may liberate molecules of the repellent substance to the air for maintaining a concentration perceptible to the sense of smell of the animals.
