Do It Yourself
In small numbers, budworms can be hand picked from a young evergreen tree or shrub. Another trick is to prune and destroy the infested shoots.
Spray infested trees with Spinosad as the buds burst in spring. Tests in eastern Canadian forests showed an 80 percent mortality rate of spruce budworms in trees sprayed with Spinosad.
