The second wave of mealybugs appeared after the first attempt to eradicate the infestation two weeks ago on my Hoya Krimson Queen. They brought spider mite friends this week. I used Dawn spray foam dishwashing detergent because it is sticky and acts like a car wash completely covering all areas including the crevices where spider mites like to nest. The teaching moment is some insects may live and continue to spread especially if their eggs hatch after the first insecticidal treatment. You have to regularly inspect your plants.
