What is stripping all the leaves off my berberis hedge?
Our Advice
This is the caterpillar stage of the Berberis sawfly, which produces several generations from May to September. Sprays of Resolva Bug Killer from Westland or Bayer Greenfly Killer'>Greenfly Killer from SMB/Bayer to kill adults and caterpillars. Also, keep disturbing the soil around the base of the plant so that the birds can find and eat the pupae.
