The next time you have a pesky swarm of bees in your back yard, don’t call the exterminator. According to a recent study, apparently all you have to do is pull out your iPhone.

The calls act as an instinctive warning to leave the hive, but the frequency confuses the bees, causing them to fly erratically. The study found that the bees’ buzzing noise increases ten times when a cell phone is ringing or making a call – aka when signals are being transmitted, but remained normal when not in use.
