The Q&A Archives: Caterpillars Stripping Pines

Question: I have gray caterpillars with black and brown lengthwise stripes eating all the needles off my white and Austrian pines. They work in groups, starting at the end of a branch and working down until all the needles are consumed. Then they move as a group to the end of another branch and repeat the process. These little monsters are about to set my landscaping back about 20 years. They are horribly quick and destructive, and I'd like to return the favor. Any suggestions?

Answer: I say you saw a saw fly! Sawfly larvae are ravenous critters all. You can spray with neem or a light summer oil to stop them in their tracks. Both are available from Gardens Alive, ph# 812/537-8650, e-mail Best of luck!
