Poolside Pests, Invasive Species to Look Out For

— Written By

Pool owners, be on the lookout when cleaning your filters this summer. What are you looking out for? Spotted Lanternfly and Asian Longhorn Beetle. These two invasive pests have been spotted in neighboring states. Spotted Lanternfly has active populations in Northern Virginia and Asian Longhorn Beetle has a confirmed population on the coast of South Carolina. Please continue reading to see what these pests look like and why they are such a threat.

Spotted Lantern Fly feeds on the sap of many species including, grapes, hops, apples, birch, tree of heaven, maple, poplar, and more. They are able to spread quickly and create a large amount of honeydew, which can produce black sooty mold on plants and objects around those plants. The two stages you would see here in the summertime are pictured below.

Asian Longhorn Beetle adults are not a threat but the adult life stage will most likely be a homeowner’s only way to identify the presence of the beetle. The larvae of this beetle will bore into hardwood trees and will eventually result in the death of the tree. The beetle feeds on 29 species of hardwoods but prefers maple trees. With North Carolina being home to many important hardwood species it is pivotal that North Carolinians be on the lookout for this beetle to preserve our forest.
