The first buzz of a mosquito is an unpleasant reminder that summer fun comes with a pesky price. We examined the science behind common mosquito myths and found that while some have a basis in reality, many are plain bunk. Mosquitoes are more than a nuisance — they carry harmful diseases such as encephalitis and malaria.
Here’s what you need to know about the season’s most unwanted guest:
1. Lemon dish soap and Listerine repel mosquitoes
Fiction: This myth has been widely circulated around the Internet. According to the Florida Medical Entomology Lab at the University of Florida, these household products do not work to thwart mosquitoes. One of the most effective repellents is DEET. The Centers for Disease Control also recommends repellents with Picaridin and oil of lemon eucalyptus.
If you use a product containing DEET, read the label and do not over-apply. DEET is a powerful chemical that can be harmful if used incorrectly. Make sure the repellent has an EPA-approved label and registration number. Use caution with small children and stick with a formulation that is made for kids.
2. Ultrasonic devices repel mosquitoes
Fiction: Save your money. According to the Department of Entomology at Purdue, these gadgets don’t work. Bug zappers do kill mosquitoes, but they also electrocute many beneficial insects including those that eat mosquitoes, so the scientists at Purdue recommend against using them.
