Milky Spore Powder - 40 oz

by Pet Foods Shop

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 inhabit the soil of your lawn 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 that are in the area, the greater the chance of infection. Each infected grub dies within approximately 3 weeks and releases new spores.

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 NemaSeek. This 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.
