All leaves eaten
My flower shrub is eaten; already sprayed with ortho insect mite and disease but it is not getting better and I can’t find any insects on it. Please advise.

You might try going out at night with a flashlight and looking for Japanese beetles. They lay eggs and the larva eat holes in the leaves. The spray you are using should take care of them but you need to reapply every 7 to 10 days and/or after rain. Also, if you see them, pick them off and drop them into a dish of soapy water. New leaves should resprout soon.
