A pharmacist, Richard Harrison of Asda, offers guidance on how to tell different insect bites apart and how to treat them. The articles describe his advice as a way for people to recognize what kind of bite they may have and to respond appropriately rather than assuming all bites are the same. Harrison is presented as explaining that some insect bites can cause different skin reactions, and that certain symptoms may indicate a more serious problem developing after the bite. The reporting focuses on practical identification cues and treatment steps, emphasizing that reactions can vary by insect type and by the individual’s response. It also frames the guidance around the need to watch for less typical or worsening signs that warrant medical attention. While the articles use strong language about the potential severity of illness following an insect bite, they present Harrison’s recommendations primarily as consumer health advice: compare the bite’s appearance and progression, use appropriate care for mild reactions, and seek professional help if symptoms suggest complications.
