@Erin-Arthur have you tried any of these yourself?
No I have not ..I do have ladybugs and praying mantis and spiders on the dirt they are eating stuff

Most of this only applies to large mature trees. I came here for helpful info, but you're telling ppl the aphids barely harm the tree, yet I have them killing young trees. The leaves will shrivel up and die off... It's an absolute disaster..
