I have a Hoya rope plant that I’ve had for years, and I love it dearly, but it has a reoccurring mealybug issue that I just cannot seem to get it to shake! I currently have it soaking in the hopes that it will help this current infestation but I am at my wits end, no matter how often I wipe it down, or soak it, or do any other kind of maintenance care, it just seems to keep coming back. Any suggestions on what to do about this insect menace?
