Why Do Spotted Lanternflies Feel Gross?
Understanding their harmless nature, huge swarms, and sticky honeydew
Are Spotted Lanternflies Poisonous?
Spotted lanternflies can look intimidating, especially when large numbers gather on trees, buildings, fences, and other surfaces. However, these insects are not toxic or poisonous to humans.
Accidentally eating a spotted lanternfly is not recommended, but they are not known for being poisonous to people. Consuming them could potentially cause a mild upset stomach, so they should still be avoided as food.
Why Do Spotted Lanternflies Feel So Gross?
The unpleasant feeling many people experience around spotted lanternflies is largely caused by their behavior and the sheer number of insects that can appear together.
They can swarm in massive numbers and may crawl or fly around people without showing much fear. Seeing hundreds or thousands of insects covering a surface can make an ordinary outdoor area suddenly feel uncomfortable.
Their presence can become even more unpleasant because of the sugary substance they leave behind.
The Sticky Problem: Honeydew
Spotted lanternflies feed on plant fluids. As they feed, they excrete a sugary liquid commonly called honeydew.
Honeydew can accumulate on leaves, branches, vehicles, outdoor furniture, sidewalks, and other surfaces underneath heavily infested plants.
What Happens to the Honeydew?
The sticky honeydew provides a food source for fungi. Over time, a dark, slimy-looking growth called sooty mold can develop on surfaces coated with honeydew.
This combination of sticky surfaces and black mold is one of the main reasons areas with large spotted lanternfly populations can look dirty and feel unpleasant.
Three Reasons People Find Them Unpleasant
Massive Swarms
Large groups can gather together, making their presence difficult to ignore.
Unafraid Behavior
They may remain around people instead of immediately fleeing, which can make encounters feel uncomfortable.
Sticky Honeydew
Their sugary waste can coat surfaces and encourage the growth of dark sooty mold.
Are They Dangerous to Touch?
Spotted lanternflies are not venomous insects and do not have a stinger like bees or wasps. Their unpleasant reputation is mainly associated with their appearance, swarming behavior, and the honeydew they produce.
As with any wild insect, it is sensible to avoid deliberately eating them or handling large numbers unnecessarily.
Spotted Lanternflies and Their Mess
One reason a spotted lanternfly infestation can be especially noticeable is that the insects may gather in large concentrations. When many insects feed in the same area, the amount of honeydew can increase significantly.
Surfaces beneath infested plants may become sticky, while sooty mold can create a black coating. This visual and physical mess contributes greatly to the “gross” reputation of spotted lanternflies.
Fact: Spotted lanternflies are not toxic or poisonous to humans. Their unpleasant appearance and the mess they create are different from being poisonous.
