Hi Yield grub free
By Joe on April 22, 2011
Verified PurchaseApplied day after receipt, still have some grubs a couple weeks later. Armadillos are still feasting on them digging up my yard. Grubs in Florida may be immune to this stuff now. I need to find good old liquid chemicals.

QJapanese Beetles
When do I treat, I am tired of loosing my garden each year what is my best attack method....thanks
AYou would need to apply the Hi-Yield Grub Free Zone 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.
