St. Gabriel Organics Milky Spore Powder

Milky Spore contains a naturally occurring bacterium called Paenibacillus popilliae. When Japanese Beetle grubs ingest the powder while feeding on grass roots, the bacteria multiply within the grub, eventually killing it and releasing more spores into the soil to protect your lawn for years to come.

Yes. Milky Spore is an organic, non-toxic solution that is safe for use around children, pets, and beneficial insects like earthworms and bees.

No, this is a one-time application product. Once established in your soil, the spores can provide effective grub control for up to ten years, with the potential to last as long as twenty years.

Milky Spore is specifically formulated to target the larvae of the Japanese Beetle. It is not designed to control other types of grubs, such as European Chafers or June Beetles.

For the most even coverage, you should use a dedicated Milky Spore dispenser or a hand-held spreader. Place the powder in spots spaced about four feet apart in a grid pattern across your lawn, then lightly water the area to help the spores settle into the soil.

Because Milky Spore is a biological control, it is not an instant fix. It typically takes one to three years for the spore population to build up sufficiently in the soil to provide full, long-term protection.
