One type of these wasps feed on aphids. The other type feed on the insects aphids prey on. Both types are likely to make use of already damaged or weakened canes for nesting purposes.
In either case, they are not likely your main problem, but rather a secondary problem arising from either a current or past infestation of aphids.
If you see your canes starting to be damaged, cut off the damaged part of the cane. The nests are usually fairly shallow, and can be repruned to a lower bud, or you can look for where the borer got in, and try sealing up the hole with wood glue (like Elmer's).
Once you reprune or seal up the holes, the wasps should try and seek out other food sources. To prevent cane borers in the future, your best bet is to be vigilant about controlling aphids.
The brown bugs you are describing may be earwigs or pincher bugs, roll up a newspaper get it damp and leave near the rose bush base, in the morning, throw the damp paper roll in a baggie and tie off, the earwigs love damp/moist places and will crawl into the paper roll. do this until you don't have any more problems, usually takes a few days. Good Luck! Dee
The brown bugs that get in between the petals are japanese beetles and they do alot of damage. You can buy japanese beetle traps at Lowes or Home Depot.

Can you tell me what bug is on this rose? Thanks.
Roses can be a happy place for several types of bugs but most respond to home-made sprays.
