    I've got pure Neem oil, think I should use that? I'm no expert on pests, so I'm going by what to do from here! I thik I'll treat every plant that comes in from a trade from now on with insecticide regardless.

    Does anyone have a picture of scale? Logically, the word itself is an indicator, but.... Im not sure if I would recognize it if a plant had it.

    Here's what people are usually referring to when they mention scale on a house or greenhouse plant - hemispherical scale. But there are many others and some are serious agricultural pests.

    Thanks, Bruce. Can' say I've ever seen that on a CP, though.

    I've seen it on a Ceph; I think I found one on a Nep; but have never seen it on a Sarr. That particular scale doesn't overwinter outdoors in the north and there are plenty of predators outside that will control it. I think they attack the young crawler stage. But the predation ends as soon as plants come inside and scale can have a population explosion if they like the host plant. Citrus and spider plants are two I've noticed and, because of that, I don't have either anymore.

    For the Orothene I used like 1/4th of the directed Dosage and it got them away. Mine was mostly for Spider Mites though

    Cheers

    Scale love Darlingtonia plants. A good systemic insecticide, preferably a drench rather than a spray, used at full strength will deal with them without damaging your plants. It is not wise to use insecticides at half or quarter strength to deal with any insect attacks, insects can become develop immunities to insecticides when given mild doses.

    The scale insects have to be scraped off the plants. They will still remain attached even when dead, they don't do any harm once dealt with but they don't look very nice and if removed it is easier to see if there is any reinfestation at a later stage.
