How to Get Rid of Wire Worms in a Garden

By Heather Bliss ; Updated September 21, 2017

Wire worms are a common garden pest in the United States. White or yellow in color, the worms thrive in warm climates, congregating in moist soil until they turn into beetles in the spring. Wire worms are a detriment to a garden because they devour garden plants--particularly fruits, vegetables and flowers. Getting rid of wire worms is easy to do by luring them out of hiding with objects you may already have around the house.

Cut a raw potato into large chunks at least 1 inch thick and 2 inches long.

Dig 6-inch deep holes every yard or so in your garden. Wear gloves and pick out any visible wire worms in the holes.

Skewer the potatoes on the sharp end of barbecue skewers. Place the pieces of potato in the holes with the stick jutting out and fill the holes with dirt.

Dig up the potato chunks in the evening. Destroy the potatoes and the wire worms they have collected.

Replace the potato on the end of the skewers and repeat until you have successfully rid your garden of wire worms.
