Adults rest under leaves making them difficult to spray. Eggs and young are not affected.
Adults lays hundreds upon thousands of eggs. There are males and females but mating is not necessary for reproduction.
Removal is a good control. The normal cycle from egg to adult is 30 days in a warm environment.
Maintaining a temperature below 62°F will slow hatching. White flies hatch from eggs that look like white dust on the underside of leaves. Whiteflies die if frozen.
Biological control is obtained with a species of mite.
