Mealybugs look like white puffs of cotton. They suck plant juices and heavy infestations will coat the leaves with sticky honeydew. Use house plant insects sprays according to label directions.
Scales are usually brown, hard shells attached to the stems or undersides of the leaves.
Sprays are not effective since the shell protects the insects. Heavily infested plants should be discarded. Physically removing the scales and then controlling immature stages with sprays may control the problem on lightly infested plants. Visuals associated with this text.
