When fully grown these pests are about ¾ in. long, yellow or yellowish-brown, with hard, smooth skins. Land recently broken up from grass is frequently infested. Wircworms do considerable damage to potato tubers, lettuces, dahlias, carnations, pinks, delphiniums, Michaelmas daisies, lupins etc. Aldrin or gamma BHG (lindane) insecticides are the best remedies and should be applied strictly according to the manufacturer’s directions.
