If you have apple trees and want to monitor codling moths to determine the best time to spray, use our Codling Moth Traps.
Periodically looking into the trap in search of captured moths will alert you as to when the moths are present and therefore when to spray.
When codling moths first appear (usually when about 3/4 of the flower petals have fallen from the tree), wait one week and spray every 10 days with Captain Jack’s, (Spinosad) for 3 applications. Some gardeners have had satisfactory results spraying only Captain Jack’s, which is organic, others start with a single application of Sevin, which is not organic, followed up with 3 sprayings of Captain Jack’s. Replace traps monthly and repeat spray regime after additional generations of moths are trapped.
