The adults lay eggs inside stems and under the surfaces of leaves. Wingless nymphs feed on plant sap. They excrete a clear liquid, mixing it with the sap and air to create their protective foam. Though not overly harmful, in large numbers they can weaken a plant, stunt growth and reduce crop yields. Spittlebugs especially like strawberries, corn and legumes.
Nymphs are easy to remove by hand-picking.
Or a spray of water will knock them off the plant, preventing more damage. Destroy all infested foliage to prevent overwintering of eggs. August Home Publishing Co. All Rights Reserved.
