Most professionals recommend pulling each one off by hand and placing them in a bag of some sort prior to disposing of somewhere far away from the garden. Once you have removed them it is still not a bad idea to spray the tree or shrub with an all seasons dormant oil. Be sure to read the label and make sure that you use a product that is labeled for use during the growing season.
If you have any questions please don't hesitate to ask.
