The leaves on my knockout roses have holes. It appears that insects have eaten them. On the smallest bush, most of the leaves are missing.

    Yes indeed, it sounds like you have a beetle and perhaps a rose worm problem. I would recommend spraying them with an insecticide of choice. I use Bayer Complete insecticide spray when I have a major attack going on.
