Scale Insects


Cottony cushion scale on a citrus houseplant doesn’t look like an insect because it has no legs or wings and doesn’t move. Nevertheless, it’s a bug and it’s reproducing like wildfire. Treat it with insecticidal soap, horticultural oil, or rubbing alcohol; these are safe to use inside your home. Page 262 of our book, What’s Wrong With My Houseplant?
