I now have holes throughout my yard where the beetles have emerged. This year, I did not water my grass in July, since I read that was supposed to help kill them. I have completely replanted grass some years and other years I just let it grow back on its own. I have tried everyone retail product available and used them annually on my yard for the past 12-14 years and they still come back in certain areas every year. What can I do to kill the grubs? They are killing my yard over and over again! Shouldn't Grub-Ex, Spectracide, or Milky Spore work to at least reduce the grubs? I know Milky Spore takes YEARS to become fully effective, and that you need to leave infected grubs in the soil to spread the bacteria, but none of the grubs I have found seem to be infected. I don't want these grubs to kill the grass that is now growing, but I can't seem to get rid of them. ![]() Today, in a two-square foot area of the yard, I found 40 grubs. ![]() I killed all the grubs I could find, reworked the soil, spread humus and seeding soil, and reseeded last weekend. Again, I went out to investigate and found HUNDREDS of grubs again. I read that you can do that when you first put out the Milky Spore, but that you don't want to do it after the first application.īy late August, about three weeks after putting out the Milky Spore and the Grub-Ex, at least 90% of my grass was dead. It was getting worse and worse, so in August, I decided to try Milky Spore, but also spread some Grub-Ex to kill as many of the grubs as I could. Suspecting white grubs, I pulled up the patches and found HUNDREDS of white grubs (remember, the Spectracide is supposed to kill grubs!). In July, though, the yard started dying in patches. I did what I always have done and treated the yard in the spring (with the plan to treat it again in the fall). Everything was going well until this summer.Īlthough I am primarily an organic gardener, I do treat my yard with Spectracide to keep the ticks, fleas, and grubs reduced in number. SO, I ripped out the yard and planted fescue.
