My Dendrobium Victoria-Reginae has been in the master-bath shower now for more than a month, and it still has bugs. It keeps blooming, so it likes the location, but each time new buds appear, they are covered with bugs almost immediately. I have been spraying it with insecticidal soap, but that does not seem to stop this infestation. The problem is that the scale has plenty of places to hide on the branches, which have a lot of feathered covering.
I will have to use a stronger solution on this plant if I want it to move back into the orchid room.
