Milky Spore

Produced to USDA standards, MILKY SPORE is the safest material ever developed for control over the larvae (grubs) of Japanese Beetles.

St. Gabriel Organics’ Milky Spore is a naturally occurring host specific bacterium (Bacillus popillae-Dutky). This product is lethal to a familiar destructive summer-time pest. It targets and discriminately works to attack the white grubs of Japanese Beetles.

The adult beetle feeds on fruits, flowers, shrubs, garden plants and the foliage of some field crops. At the immature beetle stage, the grub enjoys feeding on the roots of grass and other vegetation to include stems of plants.

Turf inoculation treatments / applications with MILKY SPORE puts in place an on-guard protective blanket on your lawn.

Considered the weakest link in the chain and the most vulnerable point to introduce an infection, resident spores in treated turf are swallowed by grubs during their normal pattern of feeding; this starts the demise of healthy grubs. Milky Spore disease then begins to cripple the grub, and within the next 7-21 days will eventually die. As the grub decomposes, it releases billions of new spores.

Milky Spore is not harmful to beneficial insects, birds, bees, pets or man. The product is approved and registered with EPA, Milky Spore will not affect wells, ponds or streams.

The ideal way to combat area infestation is through organized community efforts. Large areas treated with Milky Spore can result in long term control.
