I’m not sure. I’m finding that soap may be OK overall for the adult form but maybe not for the softer-bodied larvae. I can find nothing about the effect of the rubbing alcohol on lady bugs. (Also, as with any alcohol spray, test a little area first to check for plant sensitivity, and do not apply in direct sunlight.) It might be safest to just let the lady bugs continue their task, since you have a good collection of workers!
