Good Questions: Ultrasound Pest Repellers?

Hi Apartment Therapy,

Do you know whether those ultrasound pest repeller devices actually work? They claim to be effective against roaches and mice. And will they drive my cats (or me) mad?

Thanks much for any help! Margaret

We don't know definitively, except that our mother uses them. We suspect that given the evolutionary genius of roaches and mice, they will ultimately find this amusing. That said, however, the truth is in trying and for $40 or so, we would give it a whirl. MGR
