    DH said they came off of the leaf really easily; like dirt. Is that still scale?

    Yep, absolutely!

    On the "bright" side, scale is one of the most common orchid pests around (in the US, anyways.....)

    The tough outer shell on red scale can be pretty hard for soap and "mild" things to penetrate. Personally, I'd use an insecticide and not futz around, maybe putting the plant in the garage or something to get it out of reach of kids / pets for about a week.

    Definitely scale. I've seen it before, and the kind you have seem easier to take off than the soft shell ones. I'd personally (having a little one I know the precautions used) take it out side or in a garage, spray it with a systematic insectidide (one that is good for scale), let it dry, and put it somewhere the liitle guy can't get to it.

    I'm really set against using insecticides right now. So should I throw the plant out? I'd be sad but not break my heart...

    Well, I wouldn't toss the plant because of a little scale. If all you have are a few on one leaf like that, try the Safer's thing or the rubbing alcohol / q-tip thing, seperate the plant from your others for a while, and just keep an eye on it to make sure more of the stuff doesn't pop up.

    I agree with what Louis said. if you only have a plant or two afflicted, you can wipe all the leaves, top and bottom, with a generous dose of rubbing alcohol (cotton puffs are my vehicle of choice) and keep a close eye on the plant. anything suspicious needs to be removed and re-wiped. if you do this for a while, maybe a few weeks, you stand a good chance of wiping out all the scale. the theory i suppose is that all the eggs will eventually hatch, and if you're wiping out all the juveniles before they can breed...

    I don't think you need to panic. Just stay on top of the situation and be observant. I think people run into problems with critters when they only water their plants, but never really look at them. Giving each plant a "once over" is just part of my weekly routine now. When I had a mealy problem, it was my own fault. By the time I noticed them, they were everywhere. This winter I did find a couple of stray critters and just treated the plant and a few more immediately. Never saw another one.

    Sorry about the scale! Nasty business.

    Just in case it wasn't mentioned, ISOLATE this plant until you are certain ALL scale is gone. The immature stage, crawlers, will go where ever they want. In fact, those "mealies" you mentioned having...might be worth checking those plants again...you might be seeing crawlers instead. Never hurts to double check?

    Wishing you a speedy kill and good luck...
