Wireworms are very thin, yellow, pink or orangish worms that feed on potatoes.
Wireworms also feed on other plants in the vegetable garden such as lettuce, beans, peas, beets and carrot plants. Wireworms are very shiny garden pests. These insects have hard, jointed bodies which can be a light creamy pink color to shades of yellow and orange. They are rarely found singularly, and more often than not if you see one wireworm you will see several more very close nearby at the infestation site. Damage from wireworm infestation appears in the form of potato plants' growth being stunted or incredibly slowed as compared to normal growth patterns of potato plants.
