Scale insects are parasites on many evergreen and deciduous plants. They can occur on leaves, twigs, branches or trunks. These small pests feed on sap drawn directly from the plant’s vascular system. These pests are often controlled with horticultural spray oils, biological control or pest resistant plants.
Preventive maintenance is the most cost-effective way to keep your landscape trees and shrubs from infestations. Healthy plants resist insects, diseases and damage. As such, it is important to have an arborist inspect your property and recommend appropriate action.
