    Is there a natural way to get rid of these scale insects on evergreens?

    Hi Chuck –

    I’ve always cut out heavily infested areas and used horticultural oil to kill scale. It works by suffocating pest insects, and their eggs, and can be sprayed on most plants. A quick look at the label, shows that it can be used on conifers and broadleaf evergreens, but that it “removes the glaucous (blue) bloom from such evergreens as Colorado Blue Spruce and Koster Spruce.” Use caution and test spray oil sensitive plants. Here’s a link that will help you get rid of these sap-sucking insects using least-toxic methods.

    Hope it helps!
