Milky Spore is the bacterium Paenibacillus popilliae (formerly Bacillus popillae). This bacillus is primarily lethal to Japanese Beetle grubs. The life cycle of the Japanese beetle includes the immature beetle, called a grub. The grubs stay in the soil of your yard and garden, feeding on the roots of your grass and other vegetation.

Once Milky Spore is applied, the grubs ingest it as a normal part of their feeding. The more spores are in the area, the greater the chance of infection. Each infected grub dies within approximately 3 weeks and releases new spores.

In warm climates, good control of the Japanese beetle can occur with applications made for 3 consecutive years; in cooler climates application may need to be made between three & five consecutive years. Once applied, it will remain active in the soil for many years. 

Milky Spore is not affected by:

  • Freezing or other adverse environmental conditions.
  • Most fertilizers, pesticides, herbicides and other lawn chemicals.
Milky Spore Powder is considered harmless to food crops. It may be used in gardens, around pools and near wells. Milky Spore is not known to affect pets, beneficial insects, fish, bees, birds, other animals, plants, or man.

Milky Spore's effectiveness can be enhanced by the use of beneficial nematodes - specifically NemaSeekThis beneficial nematode is unharmed by Milky Spore and helps spread it as the nematode moves into the soil pursuing grubs, weevils and larvae in your soil. Apply Milky Spore dry, then water in the NemaSeek for complementary control of pests in your soil.
