Full Answer

Milky Spore powder must be applied directly to the lawn and not premixed with water and sprayed on. If possible, apply Milky Spore shortly before rainfall. If there is no sufficient rainfall available, water your lawn with a hose for 15 minutes or longer to allow the treatment to soak into the soil. It is best not to apply the treatment to frozen ground, but any other season is fine.

Milky Spore powder can also be applied to the ground using a dispenser. A homemade dispenser consists of a coffee can with 15 nail holes punched into the lid. Tape the can 6 inches from the bottom of a 4 foot stick, and sprinkle Milky Spore onto the ground. One application of Milky Spore lasts approximately 10 to 20 years.

Milky Spore is a non-toxic, naturally occurring bacterium called Bacillus popillae that is harmful only to Japanese beetles. The grubs of Japanese beetles become infected and die by ingesting a bacteria spore. Milky Spore is safe for both pets and children, and it is not a chemical pesticide.
