I have nuke proof Citrus Mealybugs this year. And had some Aphids. Brought ladybugs into the garden for eradication this year. Normally release early as preventative. Took 25 3 weeks to propagate. I now have almost no pests and hundreds of alligators and beetles. Best thing ever after infestation of soft bodied parasites. I knew they worked. But never saw them in action with prolific food sources. Been lucky most years. Knock on wood. If you can spend $50? And have a few weeks before harvest? I would highly recommend.
