Western corsair bug possesses a mild toxicity that is delivered through stinging, which is a characteristic defensive and offensive mechanism active in adult stages. When western corsair bug stings, humans might experience a minor local reaction, typically slight pain and swelling. Sensitivity to the toxin may vary, causing more pronounced discomfort among some individuals. Domestic pets like dogs and cats can also be affected, showing similar symptoms. Other animals, specifically smaller creatures, may suffer more due to their size and sensitivity to toxins. This contact does not generally result in severe consequences but serves as an effective deterrent against potential threats to western corsair bug.
