    Angry One of these days I will learn to quarantine new arrivals!

    In September I bought a Brassia and brought aphids into my house. in December I received 3 plants from my orchid society, and discovers this morning I have mealy worms or something that leaves white fluff on the leaves. The aphids I just wash away when I see them , but white fluff I find annoying.

    So, my question is, being a window sill grower, what do you suggest to use as a systemic pesticide?

    If you are a window sill grower you could just take the new plants to the bathroom sink and wipe them down with alcohol, maybe soak them in the bathroom sink with a few drops of ajax dish soap. Some plants are sensitive to the harsher chemicals so be careful.

    I agree with the mild dish soap, wash the leaves and rinse, if it's not that many plants

    Dishsoap can be tricky to dilute properly. Rubbing alcohol is a good solution. First wash the plant completely over and under. Throw out the soil (they can actually live there too). Clean the area kept with bleach. Repot the plant. Most households use 70% rubbing alcohol so you will need to dilute it. I find two tblsp. per one cup water works without damage.

    You will still want to keep it seperate from the other plants. Mealy bugs do not spread rapidly but they do spread. Once they spread it can be awhile before you notice them on the other plants. You wouldnt want to get one plant cleaned up only to have it get reinfected later by another plant.

    I hate, hate, hate mealy bugs! I had a severe outbreak once that was only brought under control with a pesticide that you apply in a spray and also by watering with it. The damage they did was horrible! If its a small number try the mentioned solutions and maybe even use qtips to hunt them down one by one. Check under all leaves and in any crevices, folds and especially blooms. Good luck!

    Thanks for all the great suggestions. Guess I'll go with alcohol and Q-Tips, and see if that stops them. IThe one with 'fluff" is a Massy, so I sent it outside!

    Just hope you learn your lesson soon. As John said a massive outbreak can lead to an expensive chemical solution that can damage your plants.

    Oh, the pesticide I used didn't do any damage at all... it was the meally bugs. Ravaged the bloomes, attacked the new growth etc... blasted little vermin! lol

    Alcohol should work good, but FYI a second line of defense you might try is Insecticidal Soap. I find it works pretty well for a variety of pesties (including aphids, mealybugs, mites, scale).

    JH what did u use? Inquiring minds need to know. I've been using rubbing alcohol (just specifying, never know if a newbie might try vodka or something ) to a success but my problem has not ever (yet) went above minimal. Would be nice to have this advice just in case.
