Are moths dangerous?

"I’ve never been too bothered by moths, but someone told me that they can bite. Are moths dangerous?"

While moths are a common pest in American homes, frequently circling porch lights and keeping to themselves, they’re not unproblematic. Moth larvae are responsible for holes in clothes and can infest stored food. But are moths dangerous, and can a moth bite?

The short answer is no: most moths are not harmful to humans. They don’t bite or sting, and they aren’t poisonous. Adult moths typically have a proboscis (a straw-like mouthpart) used for sipping nectar, not biting humans. The notion of a moth bite is a myth.

What about moth dust or wing scales? Some believe that moth wing powder is poisonous, but it isn’t. The dust that comes off their wings is simply tiny scales. While it can be irritating if it gets in your eyes or if you have allergies, it’s not toxic.

Why moths can still be a problem

Even though moths aren’t dangerous in the sense of harming people directly, they can still cause issues. Clothing moth larvae feed on wool, silk, and other natural fibers, leading to damage in closets. Pantry moths infest dry foods such as grains and cereals. Infestations can spread quickly if not addressed.
