Garden Tool Variegated cutworms are in full force in the garden this time of year(Feb-May). Some of their favorite foods include primrose, foxglove, variegated water figwort, bearded iris, and chives. The little vandals only feed at night, so if you have suspicious holes on the leaves of your plants go out at night with a flashlight. Hand picking works, but must be done frequently. Spraying with Bt (Bacillus thuringiensis - Green Light BT Worm Killer is one name brand) works too, but plants must be re-sprayed after each rain. More information: North Dakota St. University
