systemic will work Lisa but for FAST results do make a spray gallon and spray also.
Ive never seen anything like that but Im sure Bayers will help!
Its also what I use for Japanese Beetles and they will be swarming the Roses,Cannas,Bananas,Grasses,Yuccas and Crape Myrtles ! They are my most hated pest but Bayer keeps them flying somewhere else
