Milky spore japanese beetle grub killer granular ready to use omri listed size 20 pounds Milky Spore granular is a six step application using a drop spreader over 2 years (3 applications per year for 2 years). Apply spring, summer and fall (Memorial Day, July 4th and Labor Day) for 2 consecutive years for best results. An all natural bacteri a that controls and prevents the grub stage of the Japanese beetle for an entire season. Once in the soil, it will remain dormant until grubs begin feeding on grass roots and ingest the bacteria. Once the grub has ingested the spore it begins to multiply. Just 1 spore will multiply into 3 billion new spores in each grub. After about a week the grub will die from the spores. As the grub decomposes, it will release all of those billions of new spores back in the soil. Once back in the soil the spores will become dormant again until more grubs come along and repeat the cycle. Rids your lawn of unsightly brown spots while controlling grubs in the soil. Does not harm man, pets, shrubs or beneficial insects. Milky spore can be applied anytime the ground is not frozen. Developed by the USDA. Treats 7,000 sq. ft.
