The new Mosquito Repellent app claims that it can keep the bugs away by running in the background of your Android phone and broadcasting a very high frequency that only mosquitoes can hear.
The Mosquito Repellent app is not supposed to drain away any of your smartphone's battery, notes CBS Miami.
The Anti-Mosquito Sonic Repeller app is supposed to work for iPhone users, but neither app promises 100 percent success.
The M Tracker app tells Android users where mosquitoes are likely to be buzzing around in their area.
However, Dr. Joon Lee, a medical entomologist at UNT’s Health Science Center in Fort Worth, Tx., says DEET, an active ingredient in insect repellents, is the best defense against mosquitoes.
“Most of the other products are unregistered [with the EPA], which means they are posing minimal risk, but the effectiveness is unproven,” Dr. Lee told CBS Dallas-Fort Worth (video below).
Dr. Lee says that products with 15-30% DEET are safer for human skin than those with 100% DEET.
Dr. Lee is not sure how effective smartphone apps would be on mosquitoes. While the apps may keep male mosquitoes away because they rely on antennae more than females, it's the female mosquitoes that bite humans.
