WEST LAFAYETTE, Ind. (WLFI) – A low-flying plane is spraying pheromone flakes over Purdue’s campus to prevent the spread of gypsy moths.

The U.S. Forest Service applied the pheromone Thursday afternoon.

The flakes are not harmful to humans or other animals, but should disrupt the mating process of gypsy moths. The moths feed on oaks and other tree species and can slowy kill of forests around the area.

The spray of campus is a way to keep the moth population down and prevent them from spreading throughout the state.
