Hiya! I've been dealing with a mealy bug outbreak on my monsters deliciosa off and on for about 4 months, now. I've been using rubbing alcohol and q-tips and wiping off all the visible ones and getting into the crevices of the plant. I've also been applying a healthy dose of neem oil all over the plant. Is there anything else I could be doing? I love this plant dearly and it worries me to see the yellow spots from damage on the leaves.

You to buy a good systemic insecticide and use it in conjunction with the regimen you are using. Mealybugs are one of the hardest sap suckers to eradicate

Non-toxic treatments such as neem or dilute alcohol and dish soap can be effective in permanently eradicating mealybugs. However, it does require a thorough coverage of all leaf and stem surfaces. Q-tips and wiping are not effective because that method fails to treat the translucent, nearly invisible juveniles that hide in tiny crevices and are out of sight.

When you spray, the solution must flow over all the plant's surfaces. Otherwise, some of the juveniles will survive between the spray droplets. Effective spraying is a messy task, but effective if done well. Do it outside in shade on a warm day so you don't have to worry about making a mess.

Thank you for the responses! I'll look into giving it a thorough wash when it's not quite so sunny outside.
