The Asian lady beetle, also known as Harmonia axyridis, is a species of ladybug that has been introduced to North America and other parts of the world as a biological control agent. While these beetles are generally beneficial to the environment, feeding on aphids and other pests, they can also pose a nuisance to humans. One of the concerns associated with Asian lady beetles is their tendency to bite, which can be painful and may cause an allergic reaction in some individuals.
Asian lady beetle bites are typically not serious and do not transmit diseases. However, the bites can be painful and may cause redness, swelling, and blistering at the site of the bite. In some cases, the bite may also trigger an allergic reaction, which can range from mild to severe. Symptoms of an allergic reaction to an Asian lady beetle bite may include itching, hives, and difficulty breathing. If you experience any of these symptoms after being bitten by an Asian lady beetle, it is essential to seek medical attention immediately.

Why Do Asian Lady Beetles Bite?
Asian lady beetles are generally not aggressive and only bite in self-defense. They may bite if they feel threatened or if they are handled carelessly. The beetles have a unique defense mechanism, where they release a foul-tasting fluid from their leg joints to deter predators. This fluid can cause skin irritation and may lead to an allergic reaction in some individuals.
Prevention and Treatment
To prevent Asian lady beetle bites, it is essential to exercise caution when handling the beetles. If you must handle them, wear gloves and avoid touching your face or eyes. If you are bitten by an Asian lady beetle, wash the affected area with soap and water and apply a cold compress to reduce swelling. In cases of severe allergic reactions, seek medical attention immediately. Antihistamines and topical creams may be prescribed to alleviate symptoms.

|---|---|
| Pain | Sharp, stinging sensation at the site of the bite |
| Redness and Swelling | Area around the bite becomes red and swollen |
| Blistering | Small blisters or bumps may form at the site of the bite |

Long-Term Effects and Complications
In rare cases, Asian lady beetle bites may lead to long-term effects or complications. For example, some individuals may experience persistent skin irritation or allergic reactions, which can be challenging to treat. In severe cases, the bite may trigger anaphylaxis, a life-threatening allergic reaction that requires immediate medical attention.
Asian Lady Beetle Infestations
Asian lady beetles can also infest homes and buildings, particularly during the fall season. The beetles may enter through cracks and crevices, seeking shelter from the cold weather. While the beetles do not typically cause significant damage, they can be a nuisance due to their sheer numbers and tendency to secrete a yellowish fluid that can stain surfaces.
To prevent Asian lady beetle infestations, seal all cracks and crevices around windows, doors, and vents. Use door sweeps or weatherstripping to seal gaps under doors. In cases of severe infestations, consider consulting a pest control professional for guidance on safe and effective removal methods.
