PURPOSE: To obtain a repelling composition having higher effect than a conventional harmful animal repellent, excellent long acting effect, having low toxicity to men and beasts and mild smell and further capable of feeling even aroma.
CONSTITUTION: The objective composition consists essentially of a mixture of natural terpenoid monomer having low toxicity to men and beasts or terpenoid oligomer or cooligomer naturally metabolized in a natural plant body and copolymer compound of these terpene monomers and phenol, vinyl, styrene or maleic acid based monomer and having ≤3000 molecular weight, usable to harmful animal whose range is wide, having low toxicity to men and beasts and capable of use jointly with other agricultural chemical. The composition suppresses ecospecies which is relatively harmful to men while existing together with harmful animals having same life system as human on the earth and can substantially bring out coexistence of human and these harmful animals.
