I have succeeded in killing infestations of thrips and spider mites on D.
aliciae by submerging the potted plants in a bucket of water over night. I
removed the plants during the day to allow the roots to breathe and the
leaves to get some light. Two or three nights were enough to kill off the
infestations. This saved the plants further distress from insecticidal soap.
