Flies are small insects that can cause big problems. They are pests that drain cattle of nutrients through bloodsucking while also transmitting a variety of diseases. Fly damage costs the U.S. cattle industry an estimated $1.5 billion annually, of which horn flies alone make up $850 million1. That can equate to approximately $30-50 per head per year loss for the average producer1. A horn fly feeds about 20-30 times on each animal per day, which equals approximately one pint of blood per animal per day. This can result in a 13-14% decrease for the average daily growth rate of nursing calves 2. Flies also cause constant stress to the animals as they must defend themselves against the biting, which in turn weakens their immune system and makes them susceptible to diseases such as anaplasmosis and pinkeye.
