Milky Spore Granular for Organic Grub Control – 20 lb
Milky spore is a bacteria (Paenibacillus popilliae) that causes milky disease in Japanese beetle grubs. The grubs feed on the bacteria while also feeding on roots, which infects the grubs. The infected grubs then spread the disease through the remaining soil. Infected Japanese beetle grubs die about 1 week after infestation.
