You mentioned to someone to apply this in July, but is it better to apply during a certain ground temperature to more precise for different regions?
You would need to apply the Hi-Yield Grub Free Zone III prior to egg hatching for the Japanese Beetle and this timing can vary from region to region. We recommend you contact your local cooperative extension office to find the best time to apply product for Japanese Beetle Grubs in your area.
