Hello, I'm an expert in entomology, the study of insects. I'd be happy to help answer your question about ladybugs.

Ladybugs, also known as ladybirds or Coccinellidae, are generally considered beneficial insects. They are predators of many common garden pests, such as aphids, scale insects, whitefly, and spider mites, which can be harmful to plants. By eating these pests, ladybugs help to control their populations and protect the health of plants.

However, it's important to note that while ladybugs are not harmful to humans in the sense that they do not bite or sting (except in very rare cases where they might bite if mishandled), they can sometimes be a nuisance. For instance, they may congregate in large numbers in homes, especially during the colder months when they seek warmth. Additionally, they can leave a small amount of excrement or a slightly unpleasant odor if crushed.

In summary, ladybugs are not harmful to humans and are actually quite beneficial to the environment due to their pest-controlling habits.
