Seems to Be Working; Good Value to Me
Started putting this on my lawn in mid-2023 to see if it would help with the Japanese Beetle infestation we get every year. They destroy my roses and crepe myrtles. I used it twice that year, three times last year, and will use it three times this year, then I will be done. It is supposed to last for several years. This year, I have only seen a handful of beetles! My crepe myrtles and roses are virtually untouched as of mid-July. I am hoping this is the reason, and I recommend it based on my experience so far. It has been easy to spread in my broadcast spreader. I do not have a huge yard, and this bag will do three treatments for me. If it continues to work, it is a great investment!

Worked great in combo with spectracide bags. Gold!
The value was a little price but I am very hopeful it will work. I am guessing you have to do it for many years as it did not kill on contact. I spread out before they nettles were to arrive. Not as many showed. But then I added spectracode Bags and boom! All gone. So combine this with the two and you are gold. Effective and achieve better plant health with no beetles. Oh I do think my rose bushes appears to be a bit smaller this year though

Thumbs up.
This stuff does work, but it must be reapplied. Keeps them at the edges of the property. My neighbors don't worry about the moles so this will always be a problem. It's very easy to use, just put it in a spreader. It didn't seem to harm any of my plants or bushes so thumbs up.

Dead grubs everywhere
It really works. I had a beetle infestation this year. They destroyed my cherry blossom tree and roses. I applied milky spore on a Sunday. In mid-October. It rained that night, but not much. The instructions say that the granules are water activated so I ran the sprinklers that Tuesday. Grubs started coming out of the ground immediately. I am a completely satisfied customer. It’s rare that you see product results so immediately. My yard is like a mine field of dead grubs I mostly live it because it’s safe for my pets and won’t kill the pollinators in my cottage style garden. The instructions say that it’s most effective with 6 separate applications. Apply in spring, summer, and fall for 2 years. I will be purchasing more for my spring application. For those complaining about it not working, it may be because you have a different type of grub. This product is solely for Japanese beetle grubs!

Best and Safer Product
This is a wonderful product in a world of forever chemicals. It is very natural and as promised it works. I have dogs so I put down before a rain or water just after to be extra safe. No worries. Once you do this treatment you really take control of the grubs. Give it a try. I doubt that you would be disappointed.

Excellent organic approach to deal with Japanese Beatles
I’m a second year of flower farmer, and for the past few years I have battled outbreaks of Japanese Beatles. Every year, I would forget about the Beatles until they would decimate my Rose crops. Last year I used milky spore in the summer, fall, and again this spring. I also put down beneficial nematodes last spring, and again this spring. So far I haven’t seen any Japanese beetle damage to my rose bushes. This product works very well, but does need to be applied three or four seasons in a row to be effective. Once you have done that three or four seasons, it remains active in the soil up to 10 years. A great organic and Safe way to deal with Japanese Beatles.
