Milky Spore
The #1 Japanese beetle control! Milky Spore (Bacillus popilliae) attacks the white grubs of Japanese Beetles. Spreads naturally as each infected beetle larvae dies, decomposes and releases billions of new spores into the soil. Time must be allowed for this process to completely saturate a treated area (2 to 4 years), but only one application is required as the disease continues to multiply on its own, as long as larvae are present. When there is no longer a grub infestation, the disease remains dormant, waiting for subsequent populations. This product is NOT registered for sale in California, Washington, Oregon, and Montana.
According to the USDA, this product can suppress the development of large Japanese beetle populations. It is NOT harmful to humans, pets or wildlife. Visit the Environmental Protection Agency (PDF) to learn more about B. popilliae.
