Flowers such as roses may be destroyed by large adult populations. Look for adults from late June through early August. In late summer roll back dead patches of lawn to determine the number of grubs present. Milky spore disease can be disseminated against grubs. Weekly sprays in July with bendiocarb will provide only partial adult control.
Traps are counterproductive unless used over a community-wide area.
Euonymus Scale - This armored scale attacks and frequently kills most species of evergreen euonymus. Light infestations on bark cause no obvious damage. In heavy infestations, leaves are covered mostly with white male covers and develop yellow spots. Dormant oil sprays should control light bark infestations. In heavy infestations, use a systemic insecticide.
