Hedonists who consume alcohol beer, do not wash, share a bed and shun sunscreen might be extra eye-catching to insects– at the very least, that’s what a study of festivalgoers found.
For their Mosquito Magnet Trial, Sara Lynn Blanken at Radboud University Medical Centre in the Netherlands and her coworkers visited the 2023 Lowlands Festival, near Amsterdam. They asked 465 guests to finish a set of questions regarding their health , diet regimen, hygiene, sunscreen application, any kind of material usage, blood type and whether they had actually slept alone the night prior to.
The team also established a makeshift laboratory in delivery containers, having 1700 captive-reared mosquitoes ( Anopheles stephensi , which can send jungle fever.
Between 20 and 35 mosquitoes were taken into a series of clear plastic containers with a perforated divider panel separating the participants’ arms from the pests, so they can try to arrive on the revellers, yet not actually attack them.
The researchers counted the amount of times the mosquitoes attempted to arrive at the festivalgoers’ arms in 3 mins compared to a decoy of cotton pads taken in sugar.
“Mosquitoes showed a clear choice for the well-hydrated, on jumps and grapes, that is,” according to the researchers. “Arm touchdowns were significantly higher in beer drinkers contrasted [with] those that had nobly abstained for a minimum of 12 hours.”
Blanken says she will not let this placed her off beer. “I would certainly simply put on lengthy sleeves and bug spray,” she says.
The scientists also discovered that the “participants that successfully tempted a fellow human right into their tent the previous night likewise verified more enticing to mosquitoes”. Sun block seemed to ward off the mosquitoes, possibly by concealing skin odor or functioning as a repellent. The scientists discovered no proof that various blood group bring in or push back the parasites.
“We found that insects are drawn to those that stay clear of sunscreen, beverage beer and share their bed,” according to the team. “They simply have a preference for the hedonists amongst us.”

Cameron Webb at the University of Sydney says it’s an enjoyable research study that he wished he ‘d thought of, yet it included just one varieties of insect, and the results would most likely vary with other types.
The researchers additionally discovered that only 4 of the participants had actually absolutely no attempted touchdowns on their arms. “The greatest take-out message for me is that the substantial majority of individuals, irrespective of all the other aspects thought about, brought in insects searching for a blood dish,” says Webb. “The reality is that if we simply advised ourselves to put on mosquito repellent and invested less time considering why insects attack us, we would certainly all probably receive fewer attacks and reduced our risk of mosquito-borne disease.”
