Well, this is the lowest tech advice you can follow. You can find it discussed here on GW if you search "spider mites". The mites love hot, dry and dusty conditions. Your plants are water stressed, that's a given. Get out early in the mornings with a water wand and drench the plants with plain old water. The water wand permits to to flush the under sides of the leaves where you'll find the webs and most of the mites. Wash them really well and repeat this a couple of times a week at first, then you can probably taper off. You'll be cleaning off the dust, dirt, chemicals, smog and bugs with their webs as well as hydrating the plants. Leaves take in water just as they release it to the air. Bathing your roses will jump start them like you won't believe. You'll drown many of the insects and make conditions so unfavorable for many others, they'll leave. Why put any more chemicals on the plants or in your garden during this heat when what will most likely be the most beneficial and effective is good old fashioned water? You do need a water wand for best results. You need to be able to reach inside the plant and thoroughly rinse off the backs of the foliage. Kim Here is a link that might be useful:

The red eye in the center means this rose must be a hybrid of Hulthemia persica. "Eyeconic" and "Sweet Spot" are the names of two series of roses with this red blotch; Bull's Eye is another I can think of. Looking up some of these varieties on HMF might turn up the identity of this variety.
