Dormant Oil Insect Control

 

Dormancy refers to the time of year when deciduous trees and shrubs have lost their leaves and are not actively growing. Dormant oil sprays can be used any time between leaf drop in the fall and bud break in the spring. The purpose of Dormant Oil applications is to kill mites and insects, such as scales and aphids, that spent the winter on the trees and shrubs. This treatment is a good insect preventative to add to your tree and shrub care program.
