Full Answer

When rotating crops, plant crops that are unfavorable to wireworms in previously affected areas of the garden. Alternately, apply beneficial nematodes to the garden during planting.

To deter wireworms between growing seasons, plant cover crops that are unfavorable to wireworms, or till the soil and apply a 2-inch layer of mulch over the area. Directly before planting, shallowly cultivate the garden. When planting tubers, allow the soil to warm before planting to ensure the pests do not damage root crops.

In areas where wireworms are present, cut a potato into several pieces, place each piece of potato on a wooden skewer or stick, and bury the pieces of potato 2 to 4 inches deep every 4 to 10 feet apart in the affected areas of the garden. Remove and destroy the potatoes at least once per week until the wireworms are no longer present.

If other methods of prevention or control do not yield results, apply a pyrethrin drench to the affected areas of the garden according to the instructions on the product packaging.
