Type B blood attracts mosquitoes is not true, because whether attracts mosquitoes and blood type does not have any relationship, whether attracts mosquitoes, mainly depends on a person’s body surface carbon dioxide concentration and body surface temperature. When a person’s body surface carbon dioxide concentration is slightly high, mosquitoes can feel the subtle changes, it is easy to attract mosquitoes to bite. If a person’s body surface temperature is high, will also attract mosquitoes to bite, so B-type blood mosquitoes is not really, the real reason for mosquitoes, is a person’s body surface temperature and carbon dioxide concentration increases.
