The Japanese Beetles are back. Usually appearing in late June, they were actually a week or two early this year. And while they have been feeding voraciously already, there are still several weeks to go of their damaging presence, possibly well into July.
The adult beetles eat the leaves and flowers of over 300 plants by eating the tissue between the veins. The larvae, called white grubs, feed on plant roots and organic matter in the soil, especially under turfgrass. This feeding may result in dead patches of turf that can be picked up like a loose carpet.
There are several approaches to controlling the beetles and their larvae, and the damage they do: it is most important to understand that the first, scattered beetles you see are scouts. Once they have found promising feeding grounds, they release a scent to attract all the later emerging beetles to the area.
