Problems for People and Property
Dripping excrement, stinging wasps and sour odor are often ugly consequences of Spotted Lanternfly.
Winged adults can attack a single tree in swarms. With so many feeding at once, the droppings (aka “Honeydew”) can look like rain pouring through the tree.
Honeydew coats everything under the tree, including cars, hardscapes, and decking. Once there, black, sooty mold begins to grow.
The combination of Honeydew and black, sooty mold creates an unpleasantly sour stench. It is also very difficult to remove from surfaces.
Even worse, the odor attracts stinging wasps. They can’t resist the tantalizing smell of the honeydew. Wasps will swarm your property for a taste. It’s particularly a problem for children playing in the area.
