Pyrethrin spray, early morning or after 6 PM, when beetles are active. Do not spray if bees, other beneficials are on plant, as spray will kill them. Spray tops and bottoms of leaves where you see beetle activity. Repeat weekly.

Car33328662, early next year, apply NEEM oil to plants, before beetles emerge from yards.
