Do dryer sheets keep mosquitoes away is common myth, but scientific evidence shows dryer sheets have little to no proven effectiveness as mosquito repellent and should not be relied upon for protection. The myth originated from anecdotal reports that scented dryer sheets like Bounce contain linalool and beta-citronellol, compounds found in some natural repellents, and placing sheet in pocket or rubbing on skin might repel mosquitoes. However, studies by entomologists at Kansas State University and University of Illinois tested dryer sheets against mosquitoes and found no significant repellent effect, with mosquitoes still landing and biting at similar rates, and any slight effect disappeared within minutes. EPA does not register dryer sheets as insect repellent, and CDC does not recommend them, instead recommending DEET, picaridin, oil of lemon eucalyptus, or IR3535. Dryer sheets are designed to soften fabric and reduce static, not repel insects, and their fragrance is too mild and not concentrated enough to overwhelm mosquito olfactory receptors that detect carbon dioxide and lactic acid. Some people report placing dryer sheets around patio reduces mosquitoes, but this is likely placebo or coincidence. Effective methods include barrier sprays with pyrethroids, removing standing water, using fans, wearing long sleeves, and using EPA-registered repellents. Dryer sheets may make laundry smell good but do not keep mosquitoes away reliably.
