By killing the larvae, or grubs, of these beetles, milky spore disease effectively and safely eliminates them. Does this Spark an idea?
-
The Problem
-
Japanese beetles are destructive in lawns and gardens, as they eat fruit, flowers, shrubs and other plants. The grubs eat grass roots and plant stems.
Ingredient
-
Milky spore powder contains the bacteria Bacillus popillae. It can be purchased at home and garden shops, as well as online.
-
Application
-
The powder should be applied at 10 lbs. per acre, or 4 oz. per 1,000 square feet. Distributors recommend applying it in a checkerboard pattern in rows 4 feet apart on grass, mulched areas and gardens.
Climate Considerations
-
In warm climates, milky spore disease can become established within a year, while in colder areas it can take up to five years. Milky spore disease kills Japanese beetle larvae for at least 15 years.
EPA Approval
-
Milky spore disease is approved by the Environmental Protection Agency (EPA) to not harm beneficial insects, birds, pets or humans. It also has no effect on wells, streams or ponds.
