Abstract
Compositions and methods for repelling an animal from an area or object are described. The compositions include an animal repellent dissolved or dispersed in a polymer where the repellent is released from the polymer over a period of time in an amount effective to repel an animal from the area. Capture of the repellent in the polymeric matrix allows for concentration of the repellent in an easily movable or removable device. Moreover, the repellent is not diluted by contact with water. The composition is provided in a usable form as a film, a sheet, a shaped article, pellets, or microparticles. The method for repelling an animal from an area or object includes preparing a device incorporating the above compositions and placing the device in an area or near or on an object desired to be protected. The devices can be manufactured by solvent evaporation, solvent removal, coextrusion, spray drying, and hot melt encapsulation. In a preferred embodiment the polymer is ethylene vinyl acetate copolymer and the repellent is methyl nonyl ketone or animal predator urine.
