While you may not see any insects on your shrubs we take steps in the winter to prevent insect infestations on trees and shrubs next spring. Horticultural oils are used on woody ornamentals and trees to kill scale, aphids, mites, and other soft-bodied insects. The oils work by smothering the insects their eggs or disrupting the way some insects (generally aphids) feed.
Horticultural oils may also control powdery mildew and prevent the spread of plant viruses transmitted by aphids. If you have questions or concerns or would like to set up a free evaluation call 757-631-9773 today!
