Well the Japanese Beetles have attacked. They especially like my knock out roses in the front of our house. They come every year when it gets warm outside. The only way to get rid of them is to pick them off and drop them into a bucket of soapy water. They sell Japanese Beetle traps but the garden societies do not recommend them as the traps basically attract the beetles from all over the neighborhood and cause you to have more beetles than they kill. It is sad though the damage they do in a short time,.
