    I am planting annuals and notice a good amount of tiny grubs, white, about 1/4" long (max) , & about an 1/8" in diameter. They are about 1/4 of the size of other mature grubs I have seen. The Homeowner had planted things their before, that should of thrived but did not, & said she encountered the grubs when she planted before.

    Any suggestion on control measures? She would prefer organic, but might accept chemical. I need something that will kill/control the existing now, so the annuals thrive.

    Another question: Would the new style fluorescent street lights attract beetles, associated with these grubs?

    Are they June bug or Japanese beetle?

    I put out Milky Spore in my flower beds to combat the Japanese Beetles that eat up my roses.

    It did seem to have an effect last year

    In turf, a level of grubs that requires treatment is about 10 or more per square foot. If she found less, then the flower failure may be due to something else.

    Check soil moisture, fertility, acidity, excess shade, fungi, other insects.

    I am concerned about root development. There has been no sign of foilage being damaged.

    Milky spore is only effective on jap beetle grubs, must be applied properly and generally takes 3 years to begin to see results. There are other "natural" products that have proven more effective and faster acting on most grub species.

    This year the beetles aren't out yet
    I find adults like to chew on the roses more than the grubs
