Milky Spore

Eliminate Japanese Beetle Grubs for 10 Years or More!

Milky Spore is a naturally occurring microscopic bacteria (Bacillus popilliae) that kills Japanese beetle grubs before they can grow into ravenous adults. It's a long-term solution because it survives winter temperatures. The Milky Spore population increases each year, reaching peak effectiveness about three years after application, and lasts ten years or more.

Safe for people, pets and beneficial soil organisms

Use in tandem with our Grub Guard for protection during the first two years while this control reaches maximum effectiveness

For easy application, use the Milky Spore Applicator, sold separately

What Our Customers Say

"Everyone keeps asking me: what did I do to get such beautiful roses? And I have to say, it truly is the Milky Spore that has done the trick. If not for Gardener's Supply Company and Milky Spore, my garden would be infested with those shiny Japanese beetles from flowers to stems to roots."
