Even though Bonide Liquid Copper Fungicide Concentrate does not have any insecticidal properties, it can still be harmful to caterpillars and other beneficial insects. We would recommend contacting Bonide directly for advise on when this would not harm the Monarch Caterpillars. Bonide can be reached at 315-736-8231.
