We're committed to environmental stewardship, consumer health, and sustainable innovation. Trusted by homeowners and gardeners alike, St. Gabriel Organics delivers pest control that's tough on pests while being gentle on the planet. St. Gabriel Organics specializes in eco-friendly lawn, garden, pest control, and pet care products. We are especially known for Milky Spore products used to control Japanese beetle grubs naturally. The spores are ingested by Japanese beetle grubs while they feed underground. The bacterium multiplies inside the grub, destroying it and releasing more spores back into the soil. Our diatomaceous earth products are for pest control, livestock care, and feed applications. Protect your lawn the natural way with Milky Spore Granular, an organic solution designed to target and control Japanese beetle grubs at the source. Powered by Bacillus popilliae, a naturally occurring bacterium, Milky Spore works by infecting and eliminating grubs before they can damage your turf. Once applied, the spores multiply in your soil, creating long-lasting protection that builds with each season. This slow-release, self-replicating system means fewer applications and better control year after year—without harming the environment. Safe for people, pets, pollinators, and earthworms, Milky Spore is ideal for eco-conscious homeowners and organic gardeners looking to maintain a lush, grub-free lawn. With no harsh chemicals, no re-entry wait time, and no harm to your local ecosystem, it’s a smarter, safer way to guard your green space. Milky Spore doesn’t just kill grubs—it builds a natural defense system in your lawn. Once applied, the spores multiply as grubs ingest them, creating a self-sustaining cycle of protection. Over time, your soil becomes naturally fortified, helping to reduce future infestations for years to come with minimal maintenance. Get back to enjoying your yard right away. Milky Spore Granular is completely safe for children, pets, and people—there’s no need to wait after application. Simply spread and resume your outdoor activities with peace of mind. Unlike harsh chemical treatments, Milky Spore targets only Japanese beetle grubs. It won’t harm beneficial insects like bees and butterflies, nor will it disturb earthworms or essential microbes in your soil. It’s a smart choice for gardeners who care about pollinator safety and overall soil health. Milky Spore is powered by Bacillus popilliae, a naturally occurring bacterium that specifically affects Japanese beetle larvae. It’s a targeted, biological solution that aligns with organic gardening practices while being highly effective at reducing grub populations. Timing is key: apply Milky Spore during the grub's active season—typically spring through fall—for best results. Whether you’re using a broadcast spreader or a handheld powder dispenser, Milky Spore’s granular formula is easy to apply across your lawn and garden beds. Milky Spore is an eco-conscious solution you can feel good about. It poses no threat to nearby water sources, wildlife, or surrounding landscapes. Whether you’re treating a backyard garden or a large lawn, you can trust that Milky Spore works in harmony with the environment.

Happy with results so far. Great product for grubs and moles
Size: 15 LB Bag Style: 15lb
So far so good. I have horrible issues with Moles and Japanese beetles. After a lot of research I came across Milky Spores. I have applied two application and I am seeing results. I do plan following the suggested treatment plan until I reach two years. I do recommend if you are looking for something that is sustainable and long term ... show more

No grubs seen after application of four of six bags
Size: 15 LB Bag Style: 15lb
This is hard to find locally so I was glad to find it here to continue with our lawn care. Instructions say to apply 6 bags over two years for 10-15 years of grub control. We applied three bags last year and just applied a fourth. I was planting flowers this week, I didn't come across a single grub so I can safely say this works. ... show more

Should use a drop spreader!
Size: 15 LB Bag Style: 15lb
Last fall and through the summer raccoons were destroying areas of my backyard every night looking for grubs and poisons and motion detector alarms wern't working. I had thousands of grubs in my yard that the raccoons were digging for. The adult grubs are Japanese beetles that stripped my grape vine leaves later when they transformed. I didn't know they were different stages of the same creature! The Amazon ad has several photos and one is someone pouring the product into a broadcast spreader but the instructions stress to only use a drop spreader because the product is very dusty, even the granules. I only had a Scotts broadcast spreader so I had to use eye and breathing protection and was very careful to walk slowly. It worked but a drop spreader would have been much more effective. I applied the product in early November and it's not very cold yet here in north Georgia so I hope it wasn't too late for my first application. The instructions say to apply 3 times a year for two years for most effective results. Keeping my fingers crossed I am saving my yard and my grape vines! ... show more

Help for Japanese Beetles
Size: 15 LB Bag Style: 15lb
This bag is expensive, and I have a huge yard, but I have noticed a major difference in the amount of Beetles in my yard so far this year.

Seems to work on eradicating Japanese Beetles
Size: 15 LB Bag Style: 15lb
Have had HUGE issues with Japanese beetles. Already applied the milky spore for a complete year and had 20% less last year after only ONE of three treatments. This is my second year, and it is easier to buy from Amazon and have it delivered! I recommend subscribe and save so that you get it in time to apply in Spring, Summer, and Fall. This year, hopefully, I will have next to none. The two neighbors had bad Japanese beetle infestations last year while mine dropped to around 20%. I convinced them to purchase this from Amazon and use it. If you do get this, also inform your neighbors as the more lawns that do not have these grubs, the better. This is SAFE for animals and humans! ... show more

Talk about Shrinkflation!
Size: 15 LB Bag Style: 15lb
Don't get me wrong, I like the product. What I didn't like was the fact that over the past year the bag went from 20 lbs. to 15 lbs. and the price increased from about $39.50 to $45.50. That's a 25% decrease in product coupled with a 15% increase in price. That's ridiculous! I'm looking local next year to get my Milk Spore. Talk about taking advantage of consumers. This is a classic example!!! ... show more
