Invasion of Japanese beetles!

September 20th, 2012

Have you noticed an increase in grubs or moles in your lawn this summer? We have seen much more mole damage this year due to the increase in Japanese beetles. Japanese beetles came to America from Asia in 1916 and have become a serious problem, in grub form they feed on the roots of grass and when they mature into adult form they feed on over 300 plant varieties. Their favorite varieties are linden trees, birch trees and roses.

Treatment: There are a few options to protect your landscape from this destructive bug. If you are seeing unexplainable yellow patches in your turf there is a good chance you have a high population of grubs feeding on the roots of your grass.

As adults they will attack your trees and eat the leaves and flowers rapidly. They make thousands of small holes in the leaves/flowers and they will fall off. The only effective treatment for the beetle is to spray the trees or plants as soon as you observe the beetle. The insecticide will kill the bugs in 24 hours. Call the office to discuss with questions or to discuss treatment.
