What are Leafhoppers? Leaf Hoppers are a destructive species of pest known to suck-sap from plants and cause plant diseases such as sooty mold. While plant damage from a single Leafhopper is insignificant because they are so small, if there is a large outbreak of them feeding on your plants, they could be at risk.

Apply diatomaceous earth to plants and/or spot treat with insecticidal soap to keep pest populations under control. Thorough coverage of both upper and lower infested leaves is necessary for effective control.
