Honeydew drippings from plants can be efficiently monitored using water-sensitive paper, which is commonly used for monitoring insecticide droplets and calibrating sprayers. --- Soft scale is covered with a protective waxy substance and is somewhat easier to kill than hard/armored scale. Dreistadt, S. H., J. K. Clark, and M. L. Flint. Calif. Div. Food Agric. Monitor and record scale densities and use the density that caused damage (dieback or unacceptable honeydew) as your preliminary control action threshold.
