Insect Problems

What Is Eating My Oak Tree?

Various species of caterpillars chew on the leaves of local oak trees. These species include: Western tussock moth ( Orygia vetusta), California oakworm (Phryganidia californica ), and Fruittree leafroller (Archips argyrospilus) to name a few. There are other larvae that may chew oak leaves. Certain conventional insecticides or formulations of Bacillus thuringensis may be used to control larvae populations. Conventional insecticides are generally non-specific to their targets, while the Bacillus thuringensis sprays are target specific to moth and butterfly larvae.

The crew that trimmed my trees has to be classified as par excellent. They sure knew how to trim trees. This is the best that my property has ever looked. Thank you. Charlie, Palo Alto
