ABSTRACT:
Annoying insects are controlled by attaching an insect control device to the body of the animal to be treated. The insect control device is a molded article, preferably in the form of an ear tag, which has been formed from a powder mixture of coumaphos, polyvinyl chloride and a plasticizer. The coumaphos is generally used in an amount such that from about 5 to about 30 wt % of the device is coumaphos. Other materials such as lubricants, pigments, stabilizers, etc. may also be included in minor amounts. The device may be formed by any appropriate technique but injection molding has been found to be particularly advantageous.
