Are Inflated beetle harmful to humans?

Inflated beetle neither bites nor stings, and the cantharidin contained in it is highly toxic. Direct skin contact with inflated beetle does not poison people.
It should be noted that when the inflated beetle is frightened, it will secrete a small amount of cantharidin from the leg. The skin after contact will be red, swollen, painful, and burning, and blisters will appear within 48h. After waking up, many people will be confused by the blisters that somehow grew out of. Fortunately, the blisters caused by the inflated beetle are temporary. Most people's symptoms will disappear within a week, and most of the recovered skin will not leave unsightly scars.

Does the Inflated beetle cause allergies?

Interaction with inflated beetle's larvae can result in allergies in a small number of susceptible individuals. Contact with these insects may provoke symptoms ranging from mild to severe, depending on personal sensitivity. Allergic reactions are triggered by toxins and occur through direct contact, advising caution around larvae. As the degree of risk varies, those affected should manage exposure accordingly.
