Insecticide-impregnated cattle ear tags release small amounts of an insecticide which are distributed over the animal in skin oils and during grooming or rubbing. Ear tags can provide long term control of horn flies and some reduction in face fly numbers. Some things to consider in selection and use follow.
Read the label before you buy. All tags are labeled for beef cattle, but not all are approved for use on lactating dairy cows. Also, check for any limitations for use, such as animal age.
