This year is shaping up to be a big one for grubs.
Grubs are the larvae of insects -- in our area, mainly Japanese beetles. They live in the soil and feed on the roots of grass, often causing significant damage to lawns. Compounding the problem, raccoons and skunks can tear up grass in search of grubs to make a meal.
This summer, Japanese beetle populations have been heavy in Northeast Ohio, insect expert Dave Shetlar reported in the most recent issue of Ohio State University's Buckeye Yard and Garden Line. More Japanese beetles mean more beetle babies. And this summer's unusually heavy rainfall has kept soil moist, providing the perfect conditions for beetle eggs to develop into grubs, he said.
The time window has closed on applying grub control products such as Merit, but Shetlar says insecticides containing dinotefuran, such as Zylam, can be applied in early August.
