If left uncontrolled, southern red mites can cause the death of a heavily infested plant. Because the southern red mites are most active in cool weather, treatment for mite control can be applied at the end of summer or through the winter. Foliar applications of miticides at 2 week intervals may be needed to obtain control. For chemical information, call your local Extension Service for recommendations. Webbing and stippling along the midrib can mean mites are there.
