In this video, Kansas State University veterinary entomologist Cassandra Olds explains the importance of insecticidal ear tags for fly control in cattle herds. She notes two common pests for cattle: horn flies and face flies.
Insecticidal ear tags, she explains, work by releasing a small amount of insecticide on the cow’s hair as the animal moves. Then, the natural oils in the hair spreads the insecticide to the rest of the animal’s body.
Flies may feed on male and female animal blood up to 40 times per day, causing production losses in cattle herds.
“Tags are a great method of control for both of these fly species,” Olds said. Applying the tags within a recommended period can help producers experience an increase of $17-$18 profit per head when using ear tags. “They definitely are a worthwhile investment.”
