Help!

Not sure what these are called a fib or something like that I have a Tahitian Gardenia that has them all over. I cannot keep up on it. I’ve tried everything, Neem oil, pesticide, plant soap ,cannot seem to shake these little buggers. Any suggestions would be awesome. At this point, I’m thinking of just cutting it way back to try to get a handle on it. I have two other Tahitians in the nearby vicinity that don’t seem so susceptible to these things. Thanks again for any help you got.
