A host specific bacterium that is effective against Japanese Beetle grubs. In their immature beetle stage, the grub enjoys feeding on grass roots. The spores that are applied to your turf are swallowed by grubs during feeding. It controls grubs for 10 to 15 years. As the grubs die they decompose and release billions of new spores.
10 oz. treats 2500 sq. ft. or 40 oz. treats 10,000 sq. ft. Control of the Japanese Beetle can be achieved with one application of Milky Spore Powder; however, it takes time to develop and take effect in the soil. Initial application is an inoculation of the soil allowing the bacteria to propagate in the soil. Once applied, it will remain active in the soil for years (up to twenty years in some cases). Place 1 teaspoon of Milky Spore Powder every 4 feet so that you create of grid of the powder. Water in thoroughly. If you are using beneficial nematodes for grub control, apply them with this watering. The beneficial nematodes will help disperse the bacillus throughout the soil.
