Yes, thrips can be a problem in hot, dry weather especially. And I see you are in zone 9a. For me, I prefer to use organic controls instead of poisonous sprays that throw the insect ecosystem out of balance. Refer to

I have not had any problem with either aphids or thrips since I ordered ladybugs (from a vendor on Amazon) and let them loose on my my affected plants after dusk one evening. That was about 5 years ago. By morning they had eaten every aphid off of my infested plants. It was so amazing! They are simply voracious little eaters!
If that doesn't work adequately, then you might also try lacewings. There is even a predatory mite that eats thrips, but I've not heard of it being commercially available.
Of course a last resort would be sprays, but I hope you don't have to resort to that. I used to have 25 tea and grandiflora roses, and used lots of sprays. But then I ended up with both monoclonal gammopathy and scleroderma. I suspect I basically poisoned myself. I wouldn't want anyone to repeat my experience!
