Breeding season for certain tree and shrub damaging insects is in the fall, particularly mites and borers. An application of dormant oil helps manage pest population by coating the insect’s spiracle, effectively smothering and preventing insect larvae from hatching in the spring to infest your trees and shrubs. Dormant oil is a cost effective option for pest management.
The optimal time for dormant oil applications is in the cooler months when trees are dormant before new growth occurs. Application timing is very important. For best results, we recommend treatments from winter to early spring, or December to February. It can be applied to trees, shrubs and other plant material. Dormant oil can also be used to treat for shot hole disease and mildew. Call us today for more information.
