Sears says there’s no Mosquito device at any of their locations. The person who picked up the phone at the Sears our reader complained about said there’s no high-pitched whining or buzz noises going on by the entrances or inside, intentional or otherwise. She had read the buzz about the complaint “on Twitter” and sent several “young associates” to check it out and they found nothing out of the ordinary, besides, of course, the plastic humanoids frozen for all eternity, forced to display an ever-changing array of affordable and sensible garments. A commenter says he thinks the real culprit is a cheapo CRT monitor:

UPDATE: We called the Sears in question and they say there’s no high-pitched ringing going on at this store. They didn’t install any Mosquito devices and they aren’t having any malfunctions right now that would cause such a ringing. The woman who picked up in women’s apparel said that in response to what was being said on Twitter, they even sent out some young associates to check out all the entrances and they didn’t hear anything.
