Beer drinkers may be more attractive to mosquitoes than those who don’t drink, according to recent research from the Netherlands. The study suggests that lifestyle habits, particularly alcohol use, could affect how often someone is targeted by these biting insects.
The research, led by Felix Hol from Radboud University Nijmegen, was conducted during the 2023 Lowlands music festival. Researchers created a temporary field lab made from shipping containers and recruited approximately 500 volunteers for the study. Each participant completed a survey about their recent habits, such as hygiene, alcohol use, and sleeping arrangements.
To measure mosquito attraction, each volunteer inserted one arm into a specially designed cage filled with mosquitoes. The insects could sense body odor through small holes in the cage but couldn’t make direct contact. Cameras recorded how many mosquitoes landed on the arm compared to a sugar solution also placed in the cage.
Drinking beer may attract mosquitoes
Analysis of the recordings revealed a strong link between beerconsumption and mosquito attraction. Participants who drank beer were around 35% more likely to attract mosquitoes than those who hadn’t. The researchers believe alcohol may change body odor in a way that makes people more appealing to the insects.
Other factors also appeared to influence mosquito interest. People who had recently shared a bed with someone were more likely to draw mosquitoes, suggesting that close human contact may affect scent. Conversely, those who had showered recently or applied sunscreen were less attractive to the insects.
Researchers noted that these findings reflect how daily habits could influence mosquito behavior. The study, which is currently available on the bioRxiv preprint server, highlights a need to better understand personal risk factors in mosquito exposure.
Insights may help reduce risk of disease
Though limited to one event and group of participants, the study provides valuable clues about how to avoid mosquito bites. The results may be especially useful for public health campaigns focused on preventing mosquito-borne illnesses such as malaria and dengue.
Researchers emphasized that simple lifestyle changes — such as reducing alcohol intake, maintaining good hygiene, and using sunscreen — could help individuals lower their chances of being bitten, particularly in areas where mosquito-borne diseases are common.
Mosquitoes remain a global health concern, especially in tropical regions. In Colombia, a surge in yellow fever-related deaths triggered a massive vaccination campaign nationwide. Studies like this may offer low-cost, practical ways to reduce risk and limit the spread of serious illnesses.
