How & when do I use Neem Oil to kill Japanese Beetle grubs in turf?

Answer:

Bonide Neem Oil Concentrate is not labeled for grubs and would not be recommended. Neem Oil could act as a suffocant for adult Japanese Beetles at the time the insects are present.  Hi Yield Grub Free Zone would be a better option for grubs. The best time will vary depending on the region you are in. You should contact local cooperative extension office to determine the best timing for grubs in your region.  We have a great article as well on "How to Get Rid of Grubs"
