Lanternfly Obsession
August 1st, 2023
Since the prolific spotted lanternfly first showed up in America nearly 10 years ago, it’s been causing near panic as it spreads from one area to the next.
Some people go crazy when these inch-long flying bugs and their spotted nymphs show up en masse, fearing they’re going to kill the whole landscape and make outdoor life as we know it unbearable.
They’ve been fighting back by stomping, swatting, engaging in social-media “squishathons,” and in worst cases, hauling out homemade weapons such as kerosene, vinegar-and-soap concoctions, propane torches, and at least in one case reported by Penn State Extension, spraying trees with hairspray and igniting it.
This is where I begin to worry… not about the lanternflies but what destruction people are going to do to plants, the landscape, and themselves.
I’m not minimizing what an annoying nuisance these bugs are.
They mass, they disgust people, they suck the sap out of trees and plants, and they can “rain” honeydew (their liquid waste) down on plants and picnicking people. The honeydew can lead to black mold on plant leaves, fences, outdoor furniture, and such.
On the bright side, though, lanternflies don’t bite, don’t sting, don’t spread human diseases, and don’t even bring any stinky carcasses inside in winter like that previous hysteria-inducing insect, the stinkbug.
Penn State Extension even points out that other than grapevines, the weedy tree-of-Heaven, and possibly a few species of tree saplings, lanternflies don’t kill plants.
“While lanternfly feeding can stress plants and cause localized branch damage, it is not known to directly kill other plants,” Penn State Extension says. “It is currently considered to be primarily a nuisance pest in residential landscapes.”
