Hinder that start of a Japanese beetle infestation with the St. Gabriel's Milky Spore Granular Japanese Beetle Grub Control (3-Pack). Made from natural bacteria, the milky spore granules kill Japanese beetles in their grub phase by eating the grubs from the inside. Grubs feed on the roots of plants and can kill home crops or produce dead spots in your carefully cultivated yard. This granular powder can be used around waterways, and won't harm humans, animals, plants, or beneficial insects. Guaranteed to perform for up to 10-years, the milky spore grub granule application has the potential to last up to 20-years. This container of grub insecticide needs application in Spring, Summer and Fall for 2 consecutive years, for up to 7,000 sq.ft. each time. Use a drop spreader (sold separately) for easy, uniform application, and gently water your lawn within 24-hours. Your lawn should not be mowed until the granules have dissolved into the soil. Keep you lawn and garden Japanese beetle grub-free for up to 20-years with the St. Gabriel's Granular Japanese Beetle Grub Control, 20 lbs. (3-Pack).
