St. Gabriel Organics - 15 Pound Milky Spore Granular Natural Japanese Beetle Grub Control and Repellent for Lawn and Garden Care

So far haven't seen any beetles emerge. I'm going to use as directed, 3x yearly for 2 years to reduce the population of Japanese beetles in the area. Milky spore is harmless to wildlife, livestock, cats, dogs, and other insects, but it will build up and replenish itself after regular application over two years.

Easy to apply and I’ve noticed less Japanese beetles!

Great for getting rid of moles. Kills the grubs theyfeed on. Find a mole run and put the spores down. Complete areas of my yard are free of moles and voles.

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.

I placed milky spores granular grub control on my dry grass spring, summer and fall of 2024 and 2025. The granular product to me looked like small broken down rocks. My first outing I used a setting of 3-1/4. This setting wasn’t conducive as the minced rock like spores would clog the opening on my Scott’s EdgeGuard Mini Spreader. I would stop and go often clearing the constant clogging in the spreader. I adjusted to a setting of 4-1/2 which worked for me. I always spread Milky Spores the day before rain. If it doesn’t rain water your grass after spreading Milky Spores. April of 2026, I noticed a significant reduction of grubs in my back yard. My backyard is 1,540sqft. I dug up various dead grass sections as needed for patch work re-seeding. After digging in about 1,026 sqft I only removed 5 grubs! Since Milky spores reduced grubs significantly in my backyard I will do a third year to see if I see any grubs next April 2027. I can’t wait to see what the reduction of grubs looks like in my front yard this year! I used a mask, goggles, rain boots and old clothing that I didn’t mind getting messy as the spores emitted powder as I pushed the spreader. I without any reservations, highly recommend this product in the granular form!

Not much science that supports this fungi working to control japanese beetle grubs in the ground. What support there is, takes 2-3 years of 2 applications a season. So in effect you spend at least 3 years to find out it works or not. In my case, not.

Easy to spread. We'll see how effective this application was when it's summer.

This product has helped me to get rid of a multi year grub infestation which impacted my ability to grow a lawn. It is safe for pets children and wildlife. Highly recommended!
