Thank you for sharing that vivid (and completely relatable) late-night bathroom encounter! That “whap” against the light is unmistakable—and yes, it absolutely makes you jump.
You’ve done half the work already by figuring out it’s not a June bug. Let me confirm your identification, explain why it was in your bathroom, and—most importantly—tell you what you should (and shouldn’t) do if you find another one.
Good News First: The Cockchafer Is Harmless to You
First, take a breath. The cockchafer (Melolontha melolontha), sometimes called a “May bug” or “doodlebug,” is not dangerous to humans or pets .
It does not bite or sting. Those pincers on its head? They’re for eating plant leaves, not for pinching people.
It is not poisonous. No venom, no irritation.
It does not infest homes. It’s an outdoor insect that accidentally flew inside because it was attracted to your bathroom light .
So why did it pick your bathroom? You already figured it out: light.
