At first glance, the insect in these photos may look like just another harmless bug. But some insects can cause painful skin irritation when they are crushed or handled directly.
One important example is the blister beetle. Certain species contain a defensive chemical called cantharidin. When the insect is crushed against the skin, the chemical can cause irritation, redness, burning, and sometimes painful blisters.
⚠️ Should you touch it?
It’s best to avoid handling unfamiliar insects with bare hands. Don’t squeeze, crush, or rub them against your skin.
If an insect gets on you, gently brush it away or use a piece of paper or another object to move it. Wash the affected area with soap and water afterward.
What if your skin starts burning or blistering?
If you develop significant pain, swelling, blistering, or persistent irritation after contact with an insect, wash the area thoroughly and seek medical advice, especially if the reaction is severe or involves the eyes or mouth.
One important warning about viral photos
Photos circulating online often show dramatic skin reactions alongside an insect and claim that the insect definitely caused the injury. A photo alone cannot confirm the exact insect or the cause of a skin reaction. The insect shown here should therefore not be treated as a confirmed diagnosis.
The safest rule is simple: don’t handle unknown insects with your bare hands.
