How to kill wireworms Images

The wireworm, larvae of the click beetle, poses a serious threat to various crops such as potatoes, barley and corn. Most active during a wet, cool spring, wireworms damage crops by consuming the roots, stalks and crowns. The plant will wilt and die from the wireworm's heavy feeding or become severely stunted.

Chestnut in colour, the hard-bodied worm often measures up to 1 1/4 inches in length.

Till the field thoroughly before planting. Wireworms thrive in fields that have been allowed to accumulate abundant thatch. Thoroughly tilling the soil will expose worms and adult beetles to weather conditions, which will cut down on the population.

Apply a soil liquid insecticide labelled for wireworms prior to planting the field. Spray the insecticide when the soil temperature is 10 degrees C or above. Insecticides that contain bifenthrin and imidacloprid will help control wireworms.

Spread granular insecticides labelled for wireworm control directly into furrows. Follow the directions on the insecticide label to determine the correct amount to spread.
