  • Patent number: 5549902
    Abstract: A method of repelling birds from a source, comprising the step of applying to the source an aversely effective amount of a liquid bird aversion solution including a bird aversion agent in an amount of from 5 to 50% by weight of a total weight of the solution; a terpene chosen from terpene hydrocarbons, oxygenated terpenes and a mixture of terpene hydrocarbons and oxygenated terpenes in an amount of from 10% to 50% by weight of a total weight of the solution; and alkylesters chosen from saturated fatty acids having from 4-20 carbon atoms and unsaturated fatty acids having from 10-18 carbon atoms esterified with an alcohol having 1-8 carbon atoms in an amount of from 10 to 50% by weight of a total weight of the solution. The bird aversion agent can be selected from methyl anthranilate, ortho-amino acetophenone, 2-amino-1,5-dimethyl acetophenone, veratroyl amine, dimethyl anthranilate, cinnamic aldehyde or esters, and combinations of these compounds.
