well I would try to avoid bio stuff since you are going to be inhaling or ingesting the plant. I would use something that gets rid of a variety of pests..... Have you checked your soil mixture for bugs?
I have never seen this before something new to me. Cause without seeing what pest did the damage I could not say a remedy so since they keep coming back it's obviosly something is there!
Since you are using ladybugs now I would wait to use other stuff that would be put on the plant unless it's safe to use with ladybugs.
You put your plants outside?
Or do they grow in a grow room?
