The rice-sized insect, known as the Paederus fuscipes or rove beetle, is a small insect that is approximately 1-1.2 cm long, with a slender body and a red-black color. This species does not actively attack or bite humans, but contact with its bodily secretions can cause severe contact dermatitis.

Inside the body of the Paederus beetle is a potent toxin called Pederin (C24H43O9N), which is 12-15 times more toxic than cobra venom. Although the amount of toxin involved in contact is usually small and limited to the skin, it can cause burning, redness, blisters, and in some severe cases, ulcers and infections.

Symptoms of contact with the Pederin toxin:

• Early stage (6-12 hours after exposure): Redness, mild swelling, and possible itching.

• Later stage (12-24 hours): Blisters of uneven size, with increased pain and irritation.

• Further progression: Blisters may burst, leading to ulcers, pain, and the risk of infection.

Prevention and Treatment Recommendations:

• Prevention:

  • Avoid contact with Paederus beetles by closing windows, using insect screens, and replacing fluorescent lights with yellow light bulbs.

  • Before sleeping, shake out bedding and carefully check sleeping areas to remove any beetles.

• Treatment if exposed:

  • Wash the affected area immediately with clean water and soap.

  • Avoid rubbing or applying unknown substances to the wound.

  • If severe symptoms like ulcers or infections occur, seek medical attention promptly.

Increasing awareness and taking preventive measures will help minimize the risk and impact caused by the Paederus beetle.
