What you'll see: Poor or stunted plant growth; oval or round brown insects on stems and leaves.

Management: You can usually rub the scales off with your fingers; wear a rubber glove if you don't want to touch the scales. For minor infestations, simply prune off the affected leaves. A cotton swab dipped in alcohol and brushed onto the scales will kill them; the alcohol dissolves the waxy coating that protects the pests. Be sure to repeat every two to three days.
