High-frequency sonic device for pest control?

[Phisherman]

I was wondering if anyone tried those high-frequency sonic plug-in devices to ward off plant-eating pests? I grow plants under fluorescent lights and I'm wondering if these sonic devices would help with mealy bugs, aphids, scale, etc? Are these devices a hoax?

This devices are completely phony. Here's my article on the topic, with citations:
