    i've discovered scale on my odbrs today - i inspect everyone every day, mostly because they're all so new, i want to make sure i know what they look like normally, and today was the first day i saw it. four dark brown, little limpet like creatures, clinging to the underside of my odbrs.

    i've read that paph and oncidium alliegnce (i spell quite poorly after a few drinks, it seems), are particularly vulnerable to scale. is it possible those spots were caused by scale? i'm not used to my plants getting sick, so i'm not so familar with bug trace-routes.

    i've googled quite a bit, and there are plenty of pictures of scale and soft brown scale, but no pictures of the sort of havoc they play when they're not noticed right away.



    and sadly, the spots have not gone away with the listerine, and seem to be spreading despite my best efforts. i'm tempted to toss it out, to preserve my cat and my other orchids. both my paphs have it, and now i'm starting to see spots on my other orchids -- which, i freely admit, is very likely to be a figment of my imagination at this point.

    Well, the spots are never going to go away. Clearing up an infection just means you're not going to get any more of them. The listerine treatment will clear up bacterial problems but not fungal ones. You'll have to use the cinnamon for that.

    Scale thrives where it's warm, moist, and dark. They can cause spotting over time, but if there are spots and no critters, I doubt they're what's causing the problem.

    If there was a way you could keep the cat away from the plants for a while, your best all-around solution is to just buy some systemic insecticide / disease control, spray the plants a few times, and have done.

    You're right, they arent going away. They're spreading -- I cut off all the original brown spots I could, and then it just got itself some new ones. I'll have to figure out some sort of solution to this, pretty soon, before I run out of plant.


    I'll go ahead and tell myself the odbrs had scale before it came to me, for my own comfort. It's getting so much light at my window, it's actually starting to freckle.
