Do mosquito-repellent apps really work?

Posted: Updated:
MYFOXNY.COM -

What would you do if there was an app that repelled mosquitoes? Well, there are 2 free apps that claim they repel mosquitoes.

The Android app from Prothoughts releases high-frequency sound that mosquitoes reportedly don't like. And you can select several frequencies up to 22 kilohertz.

The iPhone app from Pico Brothers also claims to drive away mosquitoes. But this one says it cannot guarantee 100 percent success.

We went to an expert to see if these types of apps really work. Laura Harrington, the chair of Cornell University's Entomology Department, says published studies have shown that ultrasound has no repellent effect whatsoever for mosquitoes.

The apps offer frequencies beginning at 12 kilohertz, which humans cannot hear. But Harrington says mosquitoes can't hear it, either. She says the insects can't hear anything over 2 kilohertz.

We reached out to the app companies for comment but did not hear back.

    You've probably seen Airbnb commercials extolling the benefits of homeowners renting out their houses or apartments to out-of-town guests for a fee. Sharing is caring feel-good commercials.But housing activists say Airbnb is reducing available housing in New York City's increasingly expensive and shrinking housing market. They argue Airbnb is pushing thousands of apartments toward use as illegal hotels instead of affordable housing.

    A life-sized looking and sounding robot named the RoboThespian is an interactive, alert machine powered by algorithms and codes -- a form of artificial intelligence. It's the sort of thing that would have sounded like science fiction a generation ago. These days, robots like this are used mostly in showrooms and for entertainment. But researcher Cadell Last of the Global Brain Institute says that these bots will have a much bigger role and will make up a major part of the workforce.
