If not treated, they can kill the roses eventually. Water the plants well within the restricted parameters, and then spray the undersides of the leaves with Avid. This can be had from rosemania.com. See link below.

If it isn't on too many roses, you can fill a spray bottle with water and give them a hard squirt that way.

OR a hard blast with a garden hose, FROM UNDERNEATH the foliage.
If you are not using broad spectrum insecticides, the spider mite infestation should be pretty easy to knock down with water.

If she's under water restrictions, she can't blast 'em off. Buford they say soapy water sprayed on a plant with kill the mites. I just use a few drops of dish soap & the rest tap water in a squirt bottle. Make sure the undersides of the leaves are sprayed. If that doesn't do the trick, get a mitacide (sp?).

I'm still not sure they are spider mites. I just went out and now the 'little white' spots appear to be hopping around. Possibly adult thrips?I did see a thrip in one half opened bloom. Again, these are on blooms, not leaves or undersides of leaves.

Is need oil effective on mites? I last used insecticide sparingly in buds to get rid of thrips. That was last year.

Spider mites look like salt and pepper on the backs of the leaves. You need a magnifying glass to get a good look at them. There's a little webbing on the leaf back but to me it isn't noticable. Insecticide won't kill them, you need Avid. In hot, dry areas you may get mites every summer even though you've used insecticide sparingly. Roses planted close to the eaves ALWAYS get mites in my garden. If you can see little insects jumping on the blooms, that isn't mites.

Whitefly, maybe????
But they FLY, rather than HOP.

ok, it's not spider mites. Possibly white aphids? I took this photo with my super macro lens. I couldn't even see the brown aphids until now:

Buford, aphids periodically shed their skin and leave behind white casings in the shape of their bodies and these casings usually stick to the plant surface. I think that's what you're seeing.

Thank you Mike. They do look like little aphid ghosts. I do think it's aphid related. The leaves seem fine. I had a bad lace bug infestation on my azaleas a few years ago, so I know how that looks.

I am wondering what that small fly looking creature is in between the two smaller buds. A predator I hope!

The aphids look bad, but I don't think they are doing any damage.

Definitely aphid carcasses. (Now aren't you glad you didn't blow hundreds of dollars to kill pests that aren't there.)
At the suggestion of spider mites, my first thought was that it's still too cool. The only spider mites I've seen in May were in a garden with lots of large stones, full sunlight and next to a asphalt driveway that had just been reblacked.
What I've done when I've had a rose that seemed to be spider mite buffet was dig the rose up (they've almost always been short roses genetically) and then pot it up, keep in in a raised area and treat with a water from a spray bottle. Then, once cured, back the ground.
Predators are out there, but once you start killing, you wipe out the predators as well.

Yes Ann, I was seeing that $108 price tag and thought I'd wait it out.....

Isn't it too early for spider mites?

We, here in the coastal region, again, got less rain than any of you inland but the weather was coolish and little the rain it was I think do not warrant spider mites yet, maybe with the exception of some plants coming from greenhouses where they didn't pay attention to this issue. But most respectable nurseries would not allow spider mites take over their crop.

The fly-like creature is a winged adult aphid. Not all aphid adults are winged, but a portion are and that's one.
