What is true about Milky Spore products?

• A. Milky spore products will control Japanese beetle grubs.
• B. They are ineffective against grubs.
• C. They must be used with other insecticides to work.
• D. They have no effect on turf pests.

Answer: (A)

Milky Spore products are a biological control that targets Japanese beetle grubs in turf. They contain Bacillus popilliae, a bacterium that infects and slowly kills JB larvae living in the soil. As the spores establish, they persist and provide long-term suppression of the grub population, rather than an immediate knockdown. Because this product is species-specific, it will not control other turf pests. It does not need to be used with other insecticides to work; it can be applied on its own, though results are gradual and depend on soil conditions and proper application timing.
