Ladybugs are not poisonous to people. Most species are harmless if handled or touched, though a few can cause irritation for sensitive individuals or trigger allergies. Some orange or Asian lady beetles can secrete irritating fluids when bothered, which may irritate the skin or eyes, and in rare cases may provoke an allergic reaction. Ingesting large numbers can upset the stomach, especially for pets, but the insects themselves are not typically life-threatening to humans. Sections you might find helpful:
- Basic answer
- Most ladybugs are safe for humans. They do not carry diseases for people, and bites are uncommon. Allergic reactions are possible in sensitive individuals, particularly if there is repeated or prolonged contact with certain species or their defensive fluids.
- When to be cautious
- If you are allergic to insects or have a history of skin or respiratory allergies, limit handling and wash hands after contact.
- Orange/Asian lady beetles may release a foul-t tasting fluid as a defense; avoid crushing or squeezing them on skin or near the eyes or mouth to minimize irritation.
- Pets and household considerations
- Ingesting a small number is unlikely to cause serious harm to most pets, but large deposits can cause GI upset. If a pet eats many, monitor for vomiting or diarrhea and contact a veterinarian if symptoms persist.
If you’d like, I can tailor this to your situation (e.g., you’re dealing with an infestation indoors, concerns about a specific species, or worries about a pet).
