Mealybugs...!!
Two weeks ago a tiny small orchid of mine had a mealybug laying on it's leaf. I freaked out and tossed it away... Today I found a mealybug laying on a piece of bark in my growing area. I took the bark and tossed it away. I don't know if I should be worried or not, how do I destroy it? What should I do? I don't really want to repot my orchids since they all had been repotted the last two months.

Ugh! Hate mealybugs! The only thing I've found that works without hours and hours of effort is a systemic--I use Bayers Rose and Garden, which has imidacloprid, I think. I use it cautiously and don't leave any blooming orchids outside after use, as it is bad for bees. I know others who use alcohol and a q-tip, but I just can't manage the time for that. And when I have used that method, I found that it didn't really quell the infestation. |

Ewwww mealy bugs. I use insecticidal soap if only a few. I also use Bayer Rose and Flower insect killer. Will alternate between the 2. I save the Systemic for infestations. These can be found at Lowes,Home Depot, Walmart or just about any garden center. Bayer Advanced 24 oz. Ready-to-Use Rose and Flower Insect Killer-502570 - The Home Depot Bayer Advanced. Get More From The Blue Bottle. |

Bayer R&F is fine for orchids. I spray the top and not of leaves and also spray the growing medium. Although you can move the plant indoors if you like, I find that bees the United States very rarely visit tropical orchids. Since you have spotted mealies twice, I suspect you will keep seeing them in your plants. Treat with Bayer R&F as directed on the package (requires repeated treatment for a few weeks) and they will go away. BTW the imidacloprid pesticide in Bayer R&F is the same chemical in Advantage- brand flea treatment used on dogs, except Advantage is 100s of times more concentrated.

My idea of using cautiously: I don't do preventative spraying, so I am not spreading droplets all over my back yard (where the orchids are during the summer). I do keep a covered bucket of the stuff mixed up and when I see bugs, I either dip the plant in the bucket for a drench of the plant + medium, or I spray the individual plant with a hand sprayer. I use the bucket when repotting also. On bees: I haven't seen bees on my plants either, Catt, but I have had a few dendrobiums get pollinated and form seed pods. Something must be visiting them. Also I am concerned about droplet drift for any plants that are downwind of my shade structure. |

I've lost a few this year to mealy bug and even the systemics struggled to keep them at bay. I think I've finally got on top of it but it took a while. Sends the catt's yellow and then black.
