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!

  1. Last year my Oak trees were infested for the first time since two years ago when I moved in my house. There were yellow cocoons everywhere! They attached everywhere under the eaves, on the brick, on garbage cans, on my pots, etc. I mean everywhere!! They look disgusting. How can I prevent that from occurring this year again.

  2. Check for caterpillars and if they are present, spray with Spinosad. Thuricide will stop them from feeding, but if they are finished feeding and are migrating looking for a place to spin a cocoon the Spinosad will kill them.
