Milky Spore uses the naturally occurring bacterium, Paenibacillus popilliae. This bacillus primarily targets Japanese Beetle grubs, the soil-dwelling larval stage, before they become the destructive adults. These grubs target lawn and garden soil, causing unsightly damage to turf and crop loss where they are active. Once applied, Milky Spore must be ingested by the grubs as they feed. The more spores that are in the area, the greater the chance of infection. Once ingested, Milky Spore kills grubs within approximately 3 weeks and continues to propagate while Japanese Beetle grubs are active.
- Target-specific meaning it is safe for use around people, pets and beneficial insects.
- Considered harmless to food crops.
- Aids in keeping digging mammals out of the treated area by limiting their food source.
- Not affected by freezing or other adverse environmental conditions.
- Compatible with most fertilizers, pesticides, herbicides and other lawn chemicals.
Coverage Rate: Milky Spore Powder
- 10 oz for 2,500 sq. ft.
- 1 lb for 4,000 sq. ft.
- 2.5 lbs for 10,000 sq. ft.
- 10 lbs per acre
When To Use: Milky Spore Powder is a one-time application.
Milky Spore's effectiveness can be enhanced with the use of beneficial nematodes - specifically NemaSeek. This species of beneficial nematode actively seeks out grubs in the soil and spreads the Milky Spore as they do so. Apply Milky Spore dry, then water in the NemaSeek for complementary control of pests in your soil.
This Product Controls These Pests or Diseases: Japanese beetle (Popillia japonica Newman)
Many controls for pest insects require repeated applications with no end to it in sight. Milky Spore, however, has the added benefit of inoculating the soil after several applications. What this means is that the soil will carry enough of the bacillus that any grubs that hatch in the area will not survive. Depending upon your climate, fully inoculating the soil can take between 1 and 5 years:
- In warm climates inoculation requires 1 – 3 years.
- In colder climates inoculation requires 3 – 5 years.
Inoculated soil remains so for about 20 years. Please note that Milky Spore begins working as soon as applied so long as grubs are feeding. This means spring and autumn applications of Milky Spore are most effective because the grubs are most active at that time. Don't forget that beneficial nematodes are great for seasonal control of the Japanese Beetle. They are effective on a broad range of in-soil pest insects and they will help to more effectively distribute the powder form of Milky Spore.
How Apply Milky Spore Powder: 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, lay out the Milky Spore in a grid pattern first. Then, water in the nematodes. The beneficial nematodes will help disperse the bacillus through the soil. Refer to the Application Rates below for recommended treatment area.
