I dunno. Mealys are bad enough that I think you're going to need more than soap. Yes, leaving water on fuzzy leaves can make permanent marks on them, especially if the plants are in sun when you get them wet. But, you know, leaving mealybugs on fuzzy leaves is going to kill your plant, and possibly any other plants in the vicinity too (in fact, you should inspect any nearby plants very carefully, I think, because where there's one infestation, there are likely others). So it's kind of a question about whether you want an ugly plant or a dead plant. If it were me, I'd probably be inclined to take a few cuttings and chuck the rest of the plant in the trash: it's not worth fighting mealybugs, to me, just to have a plant that's as easily propagated as Gynura aurantiaca is. (Granted, the cuttings might have mealys too. But if you taken enough cuttings fast enough, you should be able to outrun them.) If you have sentimental attachment to the plant that makes you want to save it, I'd go with some kind of spray containing imidacloprid, follow the label directions (which usually allow for you to spray the plant weekly), and move the plant out of direct sun until the crisis has passed. The safest bet of all is to do both: cuttings and spray. If the spray works, you have multiple plants; if the spray fails, you at least have the cuttings as back-up.

Jean, yes, inspect ALL your plants.. It's the crawlers, (babies) that are hard to find.. That's the reason it's important to spray all parts of your Agave/s. Leaves/stems, etc. I think Baby Wipes contain Rubbing Alcohol, right? It's been a long time, lol. If it does, alcohol will help somewhat, but Jean, to rid those suckers, literal suckers, you better get to work. Clean and inspect daily until you get hold of Bayer or whatever you choose to use. They multiply fast. Are these guys hard-shelled? Yuck, plant bugs are gross looking, especially when magnified. I read an article that explained how eggs are in waiting, during winter months, then when climate is 'just right' they come out of hiding. Hatch. As much as I dislike Scale, IMO, they're easier to rid than Mealy.. I purchased an Olive tree from an online nursery. I ordered from this place several times, and never ever found insects, but there's always that first time, you know? The olive tree arrived. I set it beside a group of citrus and other tropicals. (BTW, it was winter, days cloudy, and my eyes aren't what they used to be.) I can't recall how many days later, while misting, I spotted a brown lump on a leaf..then another and another. Jean, I wanted to cry..there were hundreds of scales..truly that many and more. Then, I looked at citrus neighboring the olive..all branches growing nearest the Olive had loaded..which is one advantage..scale move slower than say, mites. What do you do with a hundred scale? Hand-pick each? What? Earlier in that summer I spoke with a woman in Fl who owns a citrus nursery. She's the person who told me they use Fish Emulsion as a scale preventative and insecticide. I phoned her, explained the situation, asked the portion of FE to water. She gave me the recepie, and it worked! Talk about grateful. One thing that bothered and still troubles me to this day. The olive was delivered in winter. It was very cold outside. Yet, the cold didn't bother or kill the scale. This was pre-heat-pack days..the cold didn't bother the tree either, so I don't have an answer. The olive is alive and well to this day. So are the citrus. So, IMO, scale aren't terribly destructive IF something is done, but if left to live, bye-bye plant.Good luck, Jean, Toni

My old eyes can't tell from the picture. But the easiest way to tell is to use a q-tip dipped in some rubbing alcohol and dab the spot. If it comes off or turns reddish-brown, it's a mealy bug. Mealy bugs are my nemesis.

Hi Meg, Thank you! I'm thinking of hand picking off what I see, then rinsing each stand in an alcohol solution. Most strands have dried out about an inch or so at the soil line and it all needs repotted/ rooted anyway. This plant is going to make me crazy trying to find out how often to water to keep it happy. LOL! Most of my collection is outside. This was hanging in the house, with one other plant about 4' away, I hope it's just the string of pearls affected. Good luck to you too! I know these things can be a pain! JoJo
