Spring burns reduce tick and fly populations in pastures

By Scout Nelson

Cassandra Olds, a veterinary entomologist with K-State Research and Extension, explains that spring burning is a potent method to control pests such as horn flies and ticks in pastures. Research indicates that such burns can reduce horn fly populations by up to 40%.

According to a 2023 study at K-State’s Beef Stocker Unit, cattle grazing on areas that underwent spring burning showed significantly lower horn fly burdens early in the season and demonstrated higher weight gains later.

Addressing tick control, Olds highlights that the effectiveness of burning varies. While burns generally decrease tick populations, spring burns are particularly impactful.

This is due to the ticks’ life cycle; they spend the winter hidden in leaf litter, insulated against the cold, and emerge when conditions warm. Spring burns effectively destroy this protective litter before ticks can emerge and find hosts.

Olds emphasizes the dual benefits of this practice: reducing pest populations and enhancing cattle health and growth, making it a valuable strategy in sustainable pasture management.
