Oak Tree Caterpillars
Be on the look-out for oak tree caterpillars in your oak trees. They cluster together in large groups feeding on the leaves of your trees or you may notice poop under your tree (on your patio or walk.) They can be killed with Thuricide sprayed onto the leaves or with Spinosad. If your trees are too large to spray or you just don’t want to, they will not kill your trees. The tree will leaf back out in the Spring. I have had customers say that early in the mornings they could hear them chewing the hard oak leaves. Crunch, Crunch, Crunch!
