Do the Orange Ladybugs Bite? Understanding Risks, Allergies, and Prevention Tips

When you think of ladybugs, you probably picture those cute red insects with black spots. But what about their orange counterparts? These vibrant little critters often spark curiosity and concern, especially when it comes to whether they bite.

I’ve noticed a lot of confusion surrounding orange ladybugs, and it’s time to set the record straight. Are they just as harmless as their red relatives, or should you be wary of them? Let’s dive into the world of orange ladybugs and uncover the truth about their behavior.

Key Takeaways

  • Orange Ladybugs Explained: Orange ladybugs, scientifically known as Halyzia sedecimguttata, are non-biting members of the Coccinellidae family, primarily serving as natural pest controllers by feeding on aphids and other small insects.
  • Bite Risks and Behaviors: While most orange ladybugs do not bite, they might do so if they feel threatened or during extreme conditions to seek moisture. These bites are generally harmless, causing only minor irritation.
  • Human and Pet Reactions: Some individuals and pets may experience mild allergic reactions to orange ladybugs, including rashes, itchy eyes, or respiratory issues. Proper handling and monitoring are crucial to minimize these risks.
  • Management and Deterrence: Use natural deterrents like bay leaves, essential oils, and diatomaceous earth to manage and prevent orange ladybug infestations. Seek professional pest control if natural remedies are ineffective or if infestations become severe.

Understanding Orange Ladybugs

What Are Orange Ladybugs?

Orange ladybugs, known scientifically as Halyzia sedecimguttata, belong to the Coccinellidae family. These beetles display a range of orange hues, often with multiple white spots. Their distinct coloration helps differentiate them from other ladybug species. Originating in North America, these insects adapt well to various climates. Predatory by nature, they primarily feed on aphids, mites, and other small insects. This pest control makes them beneficial for gardens and crops.

Common Misconceptions About Ladybugs

Several misconceptions exist about ladybugs, including those regarding their color. Many people assume all ladybugs possess the same behavior and characteristics, regardless of color. However, different hues often indicate varying species with distinct traits. A common myth suggests that the brighter the ladybug, the more dangerous it is. Actually, the coloration mainly serves as a warning to predators rather than indicating aggression towards humans. While red ladybugs are better known, orange ladybugs perform similar ecological roles without posing increased risk to people.

Differences Between Biting and Non-Biting Species

Orange ladybugs, like other ladybugs, belong to the Coccinellidae family. However, not all ladybugs bite. Orange ladybugs, specifically Halyzia sedecimguttata, are generally non-biting. Biting species, such as the Asian lady beetle (Harmonia axyridis), tend to be more aggressive. By observing behavior patterns and feeding habits, one can often distinguish between biting and non-biting species. For instance, while most ladybugs feed on aphids and small insects, biting species might also seek moisture or food from human skin in extreme conditions.

Situations When Orange Ladybugs Might Bite

Although orange ladybugs are typically non-biting, they might bite under certain conditions. If these beetles feel threatened or stressed, they may bite defensively. Additionally, during the scarcity of their usual prey like aphids, orange ladybugs may occasionally bite humans in search of moisture or salt. These instances are rare, and even when they occur, the bites are relatively harmless, causing minor irritation at most.

Impact of Orange Ladybugs on Humans and Pets

Potential Allergies and Reactions

Orange ladybugs, while generally harmless, can cause mild allergic reactions in some individuals. If someone has an allergy to ladybugs, contact might result in symptoms like rash, itchy eyes, or respiratory issues. A 2006 study by Dr. Kevin T. Loo pointed out that ladybug allergies, though rare, can lead to asthma or conjunctivitis. Pets might show similar reactions if they come into contact with these insects. It’s essential to monitor pet behavior around ladybugs, especially if the pet shows signs of discomfort or itching.

How to Safely Handle Orange Ladybugs

Handling orange ladybugs safely ensures minimal risk of bites or allergic reactions. When picking up a ladybug, gently scoop it onto a piece of paper or a soft brush to avoid direct skin contact. If bitten, rinse the area with water to reduce irritation. Wash hands after handling ladybugs to remove potential allergens. For pets, discourage them from playing with or ingesting ladybugs. If an adverse reaction occurs, consult a medical professional or veterinarian promptly.

Natural Remedies to Deter Them

Several natural remedies can help deter orange ladybugs. Using bay leaves, for instance, can repel these insects when placed around entry points and common areas. Essential oils like citrus, clove, and citronella are also effective. Simply dilute a few drops with water and spray around doors, windows, and other potential entry points. Another method involves using diatomaceous earth, a fine powder that can be sprinkled around the home’s perimeter and known ladybug hotspots. The powder harms their exoskeletons, effectively deterring entry.

When to Seek Professional Pest Control

If infestation levels are high and natural remedies prove ineffective, it’s wise to seek professional pest control services. Indicators for professional intervention include persistent infestations, visible ladybug swarms, or structural damage caused by ladybugs. Pest control professionals can assess the situation, identify entry points, and apply targeted treatments. They may use tailored solutions that address the root cause while minimizing harm to non-target species. This ensures a safer, ladybug-free living environment.


Orange ladybugs play a vital role in controlling garden pests. While they can bite defensively or cause mild allergic reactions, these instances are rare. Handling them carefully and using natural deterrents can minimize risks. For persistent issues, professional pest control services offer effective solutions. By taking these precautions, you can enjoy the benefits of orange ladybugs without the drawbacks.

Orange ladybugs, like the Asian lady beetles, can bite, but they are generally harmless unless an allergic reaction occurs. While their bites are more of a nuisance than a threat, it’s important to be aware of the potential for mild skin irritation or allergic responses, as outlined by Orkin. Preventing infestations by sealing entry points and using appropriate pest control measures can help reduce encounters with these insects, as suggested by Pest World.
