Those of us with particularly good hearing will be aware of the very high-pitched noise which many TVs emit, especially when they are switched on but the screen is black. The frequency of this tone is around 15.5 KHz and is determined by the scan rate of the television.
Ultrasonic pest control products
are already on the market. They emit pulses of ultrasound with a frequency around 32 to 62 KHz which rodents find very irritating.
Most computer screens can be set to run at a variety of resolutions and refresh rates. What if a computer screen could be set to generate the precise 32 to 62 KHz sounds which have the power to drive mice and other pests away?
The Rodent Repellent Screensaver does exactly this! While you are not using your PC, the screensaver changes the resolution and refresh rate of your computer monitor and alternates between a blank screen and a white screen to create the necessary pulses of ultrasound. The Rodent Repellent Screensaver could quite possibly be the world's first pest control product to be delivered over the internet, in a matter of seconds.
(?) Cell phone ring tone repels mosquitos?

I'd like proof those ultrasonic pest repellers work. |

Also works as an Canadian elephant repellant. |

Is that like a seeing eye mouse, Farmer? |
|

I am also worried that this will result in your mouse skittering away and hiding as far from the computer as it can get, gibbering and slobbering in a pool of newfound madness. |

Yes, [po], that's when we put the fear of cod in them. |
|
| |
I thought that was The Codfather? |

Expect a seahorse's head in your bed. That must be what they meant by sleeping with the fishes. |

In my experience they don't |
|

Depends upon what you pay. The ones higher up the range work reasonably well. |

Perhaps madradish has deaf pests. |

I seem to recall a former boyfriend of hers, who doesn't listen. |
