Overview

Milky Spore targets and kills Japanese beetle grubs, a familiar destructive pest, before they can grow into adult beetles. At the immature stage, Japanese beetle grubs feed on the roots of lawns, turf, and other grassy areas. The adult beetle feeds on flowers, ornamental plants, trees, shrubs, and the foliage of some field crops.

Originally developed by the USDA, Milky Spore is a naturally occurring bacteria Bacillus popillae host-specific to Japanese beetles. In areas treated by Milky Spore, Japanese beetle grub eat the spores during their normal feeding patterns. Then the spores reproduce inside the grub, eventually killing grub within 7-21 days. As the grub decomposes, it releases millions of new spores and these multiply and kill other grubs.

Milky Spore is safe for people, pets, wildlife, beneficial insects, and soil microorganisms. It does not affect streams, ponds, or groundwater. Product is approved and registered with the US Environmental Protection Agency.

Features & Benefits:

  • 10 oz. Box can treat up to 2,500 square feet
  • Targets Japanese Beetle grubs feeding on roots
  • Naturally occuring bacteria Bacillus popillae
  • Kills grubs within 7-21 days while releasing even more spores
  • Developped by the USDA and approved by the US Environmental Protection Agency
  • Safe for people, pets wildlife and waterbodies

Application:

Coverage: 10 oz. box treats 2,500 square feet.

Apply one teaspoon of Milky Spore powder to turf every 4 feet in rows 4 feet apart. It should look like a grid pattern when finished. Areas between direct applications will be inoculated naturally. Best results can be expected once the entire area is inoculated. Milky Spore requires only one application, lasting ten years or more.

It is most effective to apply Milky Spore in the summer and early fall. The soil must be above 65 degrees F when the grubs are actively feeding, which is the best time for application. It works best to apply just before rainfall, or water in lightly after application to soak into soil.

To apply Milky Spore, you can make a homemade dispenser by punching 15 nail holes into a 1 lb. coffee can, and attaching with duct tape to a 4 foot stick six inches from the bottom.

You can purchase a Dispenser Tube here.

    Milky spore powder

    Trying to control Japanese Beetle in Colorado. Easy to apply with the tube device and a moveable line staked across the yard to create the grid needed, horizontal and vertical. We are hopeful for good results next July- September

    Fingers crossed

    Used with your tool as directed. Rained that day. Hoping for excellent results against lawn grubs.

    I am giving it all the credit

    I have two cherry trees and the Japanese Beatles simply swarmed them in July! I have killed over 1000 in 2 years with traps and literally standing on a ladder and snatching them off my trees by hand and drowning them in a bucket of water (it was sort of a fun game, TBH). Last year I put down Milky Spore in August and this year I had a DRAMATIC reduction in my infestation. I think my traps killed maybe 100 and I killed another 100 or so by hand. I gotta believe the milky spore is what did it. I am getting ready to put down another application this year and hope to see even less of the critters next year.

    WORKS REALLY WELL!!!!!!

    I used this product for the first time 11 years ago. I was having a serious problem with Japanese beetles. This product almost completely eliminated the problem. Only had to deal with an occasional "visitor" to my rose garden. Also eliminated the problem of skunks digging holes in our lawn. No grubs for them to find. Tube dispenser didn't work for me. I use a small plastic container (cool whip) and a plastic spoon. Eliminates the dust problem and I water lawn every few rows so I don't have to walk over area when I'm through applying product. I strongly recommend this product. It was very potent for 10 years. I reapplied it again this Spring, 11 years after the first application. GREAT PRODUCT!

    Great Product

    The Milky Spore is very effective against the larvae of Japanese Beetles. Hundreds of them were dead in my lawn just 2 days after I treated.

    Improvement is needed to make it easier to get the milky spore out of the bag and into the applicator.

    This is what I ordered and it came

    The order arrived and I followed directions in applying. Can't tell yet if it works, need to wait until next season.
