JAPANESE BEETLES ON TREES & SHRUBS IN GRAND BLANC

Japanese beetles are starting to hatch out in the Grand Blanc area. First discovered in the United States in 1916, the adult Japanese beetle lives for 30 to 45 days. These insects feed heavily on several common landscaping plants used in Grand Blanc including, flowering crabapple, Japanese maple trees, linden trees, Norway maple, ornamental cherry trees, rose bushes and sycamore trees.

Using Japanese Beetle Traps

Japanese beetle traps are highly effective at attracting adult beetles, but do not necessarily prevent damage to your ornamental trees or shrubs. If you decide to give Japanese beetle traps a try, place them on the border of your property and away from susceptible landscape plants.

Because Japanese beetles move around extensively, frequent tree spray applications may be needed to keep the beetles from causing significant damage to valuable landscape trees. Even with a tree spray program some feeding damage is likely to occur. Our Japanese beetle control program includes up to three tree sprays starting in late June to early July, and continuing through early to mid-August.

After Japanese Beetles Are Gone

The larva of the Japanese beetle is a white grub that feeds heavily on grass roots. Grub feeding in August puts a lot of stress on a lawn because of warm weather and drought stress. If you’ve experienced a lot of Japanese beetle adults feeding on your trees there is going to be some eggs laid in your lawn. You might need to consider a grub control treatment for your lawn to minimize feeding damage from grubs.
