Can high-frequency sounds repel mosquitoes?

Dear Chris,

I was at the local store the other day and I happened to see a small device being sold that claimed to emit high frequencies (that humans can't hear) that repel mosquitoes. My question is :Is there any peer-reviewed evidence to suggest that high frequency sounds can keep mosquitoes away or are people swindled into buying a useless product?
