@goldensrbest , it may take some time to see the effects of the milky spore (it creates a disease that disables the grubs).  Also, if the lawns around you are not treated you may not see a significant difference.

 

The good news is that eventually they will be gone.  A few more weeks.

Research here on LI, NY has shown that the soil needs to be continuously warm for milky spore to be effective. The milky spore only works on Japanese beetle grubs, not the other beetle grubs in the soil. 

 

What might be a better option is applying beneficial nematodes to your lawn which work by invading the grubs through their orifices & then using them as food ala Alien movie. The nematodes must have adequate water to travel into your soil so applying after rainfall or your sprinkler system being turned on would be optimal. Generally on LI, they would be applied in August. 

Local nurseries carry them & call ahead for availability.

@goldensrbest  I live in Western NY and we went to an airshow last week, and the field that we sat in was just full of Japanese beetles

The day i first posted ,they were some ,but not nearly as many as in past years, maybe the milky spore helped.

When you lose some one you L~O~V~E, that Memory of them, becomes a TREASURE.
