What kind of holes are they? Are they neat, semi-circular holes, or do the leaves look like lace? Are your roses large and missing almost all their leaves, or are they fairly small, so that any damage is exaggerated?

Is there any way you can post a photo? We need more info in order to help you.

By the way, if the holes are neat semi-circles, you don't have a problem at all. Leaf-cutter bees are using your rose leaves for their nests. It doesn't hurt the plant in the long run, and bees (of any kind) are a great thing to have in the garden. You don't want to do anything to poison them. On the other hand, if the leaves look like lace, you have a problem...

Well they are definately lacey, and the shrub itself is large, about 4ft now and the roses themselves are an average size about 3" diametre.

HEEEEEEEEEEEELLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPP my roses.

If the pests are skeletonizing your leaves, you may have rose slugs. Here's a great source of information for you. I hope it helps.

Here is a link that might be useful: Rose slugs

They are also called Pear Slugs, Lois Hole's Rose book says if they are dark green, about 1/2" long and look a bit like slimy tadpoles, they are pear slugs - the larvae of sawflies. Pear slugs usually appear in early spring. They eat holes in leaves from the undersides, causing a skeletonized effect. The damage can be quite speedy, so react quickly. Pear slugs are among the easiest bugs in the world to kill: either brush them off and squish them, or spray with insecticidal soap.

Look for those buggers and good luck!

I started having this same problem - try the Bayer 3 in 1 insecticide (Blue Bottle) you can get it at walmart even...

Make sure you spray the undersides of the leaves

Thanks for all the info, what nasty critters, sprayed my rose with water and tons of green slimy caterpillars (rose slugs I assume) were all over the sidewalk, stepped on them of course

Havent had a chance to go to the city yet for product but I am going tomorrow before I have no roses to look at.
