Insect control device for prolonged treatment of animals containing coumaphos and diazinon.

摘要

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 and diazinon, polyvinyl chloride, and a plasticizer. The coumaphos and diazinon are generally used in an amount that would prolong the insecticidal activity without detracting from the suitability of the device.
