      A lot of research is being carried out on this as it has emerged thatmosquitoes do prefer some people’s blood to others

      Scientists do know that genetics account for a whopping 85% of our susceptibility to mosquito bites. They’ve also identified certain elements of our body chemistry that, when found in excess on the skin’s surface, make mosquitoes swarm closer.
