Even healthy trees and shrubs are vulnerable to attacks from invasive insects like the Emerald Ash Borer, Leafminer, Japanese beetles, Bagworms, Aphids, Lacebugs, Webworms, Sawflies, and more. Once these insects attach themselves to your trees and bushes, they won’t go away on their own. You need help from a professional arborist and pest control specialist.
At Aspen Lawn and Pest Control our specialists can identify and treat any problem you may discover in your trees and bushes. Contact us today and ask about our 6 Step Plant Health Care Program.
