The bee assassin bug typically has a mild venom that is secreted through fangs, mainly as a defense mechanism or to subdue prey. Adults are known for their toxic stage, and the venom affects both large and smaller animals, though the severity may vary. While humans might experience minor symptoms such as local pain or itching, smaller animals like dogs or cats could have more intense reactions. Nevertheless, the mild nature of the toxin generally does not cause severe harm to most animals.
