I have been battling a small group of these persistent bugs on my plumeria and I just cant seem to get rid of them completely. In fact they have been ever present since I got it in September. For awhile I kept them at bay with neem, then tried Azamax and most of the leaves fell off so I didn't do the follow up dose. I have also been sprinkling DE on the surface. At this point should I just continue with Azamax or is there something stronger?

And I have many plants under and near the plumeria but have never seen any thrips on them...do they just like certain types of plants?

How did you use the Neem? I ask because it is the best thing since sliced bread.
I use a quart sized spray bottle.

Fill it 95% with water
Add 1/4 tsp. Neem Oil
2 drops mild dish detergent.
Spray one day
Spray #2 a week to 10 days later
Spray #3 a week to 10 days later
Spray everything up, down over and under each time.
Then treat again a month later
Then treat again a month later
Neem is good for insect control and fungus and bacterial issues. AND it is a systemic and the plant takes it internally. If you follow my program I can guarantee success. Once into the program if you miss a month, the systemic nature of the control will keep your plants protected.
You have to be faithful in the beginning. Do not miss a step. If you follow me on this, bugs wont bother you again!!! I tip my hat to you.

You might try a product containing spinosad. Bonide Captain Jack's Deadbug is one brand, there are others. Insecticidal soap could also be helpful. I'd do a small trial first, to see if either one is toxic to the plumeria itself. Thrips like to hide, so it's hard to get any product to contact them--repeated applications will be the rule.
Yes, some plants are more attractive, and show more damage, from thrips. You're seeing them mostly on the plumeria, but I suspect there are at least small populations on your other plants.

I use Neem in a spray bottle like you do and spray/soak the plant and soil. I try to keep a good schedule but I'm sure I let it lapse. The plumeria didn't mind it, as opposed to the azamax which being concentrated was a shock. I'm open to using the neem but at this point I'd really like to eradicate the infestation quicker. And I agree, I'm sure the thrips are on other plants and the neem will help stop those cycles in the long run. I'll try the Dead Bug and just stick to something and see it through. Thank you!
