Yellow ladybugs are not poisonous to humans. You can safely let one crawl on your finger. Just don’t eat it like a gummy vitamin.
Like most ladybugs, they have a bitter taste. That’s their defense, not poison. Your tongue will just go, “Bleh,” and you’ll be fine.
But Wait—There’s a Catch
Some people call them “poisonous” because they can cause mild skin irritation. If you squish one, the yellow fluid (hemolymph) might sting a bit.
Think of it as nature’s pepper spray. Annoying? Yes. Deadly? Absolutely not. Unless you’re a tiny aphid. Then, run for your life.
