GrubOut® is an organic, OMRI listed grub control. It will help your lawn defend against damage caused by grubs and animals that feed on them.

Containing the natural soil bacterium bacillus thuringiensis (Bt) galleriae, GrubOut® is as effective as chemical treatments without any of the negative side effects or damage to beneficial insects and pollinators like bees, butterflies and ladybugs.

GrubOut® works by controlling grubs while they are looking to feed on your lawn, preventing them from causing extensive damage. Controlling grubs also keeps animals like moles, skunks, and raccoons from digging up your yard while trying to get their paws on a tasty, grub-flavored snack. Grubs grow up to become beetles, emerging from your lawn looking to feed on things like gardens, trees, and shrubs. Controlling grubs will also help to control the population of other pests like Japanese, oriental, June, and Asiatic beetles, along with chafers, weevils, and emerald ash borers in your yard. 

Safe for all turfgrass and ornamental plant species, GrubOut® is also family-friendly, allowing children and pets to get back to enjoying your yard immediately after it has been applied. For best results, water the product in after application.

What Does OMRI Listed Mean?
The Organic Materials Review Institute (OMRI) is a non-profit, third party that reviews and verifies products for organic use. The designation of an OMRI listing means that GrubOut® has passed the review process and is compliant with organic standards. OMRI listed products are the best organic products available.
