We recommend using a pyrethroid insecticide or repellant such as Talstar P? or a natural insecticide like Essentria IC3? to control adult Japanese beetles. Spraying susceptible plants every 3-4 weeks while beetles are active with the highest allowable rate on the label is important. Please visit our Japanese Beetle Control Guide for the most effective Japanese beetles treatments.
