That’s according to this article. A study has found that the insects are more likely to fly towards a person after they have consumed a pint or more. Researchers believe that they are attracted by the odour and breath changes caused when you consume alcohol. It might also be that they have to come to associate beer odour with a lack of defensiveness from drinkers. The research was part of a study into the insects to try and halt disease spread by mosquitoes. Tests were conducted on a group of people aged between 20 and 43. They were given a litre of beer and insects were given the option of flying towards traps containing either open air or the human odour of the participant. It was found that 65% of mosquitoes flew towards the human odour after the person had consumed beer compared with 35% before any beer was consumed. I wonder if the same applies to wine.
