my hoya has had mealy bugs ever since i could remember. she’s grows non stop but the bugs will. not. leave. i have tried so many things MULTIPLE times. I’ve tried: -soaking the entire plant in a cinnamon bath -spraying diluted rubbing alcohol on the plant and in the soil. it kills the bugs on contact but the next day they’re back again -i bought a pest spray specifically designed for mealy bugs -ive repotted the plant (shes HUGE) please help me!!
