Abstract: An animal tag assembly is disclosed having at least one relatively wide section along the length of the body of said tag, thicker than the body of said tag and containing a connector and optionally a washer to enable the tag to rotate. The body of the tag including edge beads is extruded from a powdered or finely divided compounded plasticized vinylchloride polymer insecticide releasing composition at temperatures below about 150.degree. C., preferably below about 125.degree. C., to provide a tag after extrusion with retention of at least about 90+% by weight of the migratory and volatile insecticide which is initially contained. The connector and washer, free of insecticide, are suitably compounded and molded from tough, impact resistant and relatively hard thermoplastics such as one of the acrylonitrile-butadiene-styrene copolymers, polystryenes, polyvinyl acetals, rigid polyvinyl chlorides, nylons and poly alpha olefins.
