Although NOT SCIENTIFICALLY PROVEN, it is said that there are certain frequencies that repel some animals such as mosquitoes, flies, wasps... It is said that the frequency used, for example, to repel female mosquitoes (those that generally bite) is that of 15khz. MOST SCIENTISTS THINK THAT THESE THEORIES HAVE NO BASIS. You can do the test yourself and decide whether or not it is true that ultrasound works as an insect repellent.
