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?
