Hello –

It sure sounds like you’re having problems with Japanese beetles, which spend about ten months of the year in the ground in the form of a plump, white grub (3/4 inch long). Like most grubs, they feed on grassroots and are especially injurious to lawns, which will show irregularly shaped patches of wilted, dead or dying grass. The adults — those shiny, green-black beetles as big as a fingernail – feast on foliage, preferring most of all your prize roses.

Japanese beetles are the worst problem many lawn-owners will face, and perhaps the worst turf pest in North America. Click on our Pest Problem Solver page to learn organic and natural methods for getting rid of Japanese beetles on lawns and landscaped areas.


Hope it helps!
