Roses almost always get spider mites on them. They usually always attack the tips, the flowers and the new buds. I have to keep a constant check on mine. My husband sprays them, I'll have to ask him what he uses. I have heard that you use sprays for spiders not your normal insecticide. I'm sending a picture of my roses to you to show you what they look like. They are very hard to see because they are tiny and green. I hope this will help you out on your issue. Let me know.
Editor's Note: These look like aphids. Spider mites are so tiny you really can't see them, just the webs they leave. You can get rid of these by just spraying them with a good stream of water, just spray them off. You will need to do it regularly.
