Blister beetles are insects that can release a toxic substance called cantharidin when they feel threatened or are crushed. Cantharidin can cause skin blisters and irritation, hence the name “blister beetle.” So, it is generally not recommended to touch blister beetles.
If you come across a blister beetle or if it lands on you, it is important to remain calm and avoid any sudden movements. The first instinct might be to slap or crush the beetle, but this should be avoided at all costs. Instead, gently blow on the beetle or use a soft object to brush it away.
If the beetle happens to land on your clothing, it is best to remove the clothing carefully and ensure that the beetle is not trapped inside. Once the beetle is safely removed, it is important to wash the exposed areas of your skin with soap and water thoroughly. This will help to remove any traces of cantharidin and reduce the risk of skin irritation.
It is worth noting that not all beetles contain cantharidin, and not all species of blister beetles produce the toxin in high quantities. However, it is difficult to determine which beetles are safe to touch and which ones are not, so it is best to err on the side of caution and avoid touching them altogether.
Additionally, it is important to remember that blister beetles can also be harmful to animals if ingested. They are known to be toxic to horses and can cause serious health issues if consumed. Therefore, it is crucial to keep an eye out for blister beetles in areas where horses or other animals may be grazing.
It is generally recommended to avoid touching blister beetles due to the potential for skin irritation caused by the release of cantharidin. If you come into contact with a blister beetle, gently remove it from your skin or clothing and wash the affected areas with soap and water. Taking these precautions can help minimize any potential harm caused by these insects.
