The beauty of your landscape is enhanced by healthy trees and shrubs. One Call's protective treatments will keep your landscape free from pests and insects all season long.
Part of that protection is applying a dormant oil spray to your ornamental trees at exactly the right time of the year to be most effective and provide the best protection. Dormant oil kills many of the insect eggs that were laid on ornamental trees the following season. Timing of this application is critical.
Not only does dormant oil control these harmful insects, but it also reduces the threat of many diseases these insects carry and can infect your valuable ornamental landscape plantings.
