Your trees and shrubs can be saved from insect damage by applying dormant oil to them. Some of the insects that can be controlled with a dormant oil spray include aphids, mealy bugs, mites, scales and whiteflies.
When using the oil, take these precautions to help get the best results:
First, read the label directions carefully, and use dormant oil only on plants that the label recommends.
Use dormant oil on a clear day when the temperature is expected to remain higher than 50 degrees for at least 24 hours.
Don’t apply dormant oil when severe freezing weather is expected within three or four days after application.
Don’t apply dormant oil when the temperature is above 70 degrees.
