Pest control and security

A small museum contacted us with the following questions. Could
anyone offer advice?

    1.  Do you know if any museums use those sonic pest control
        devices? They're supposed to emit a high pitched frequency
        that drives away mice. I haven't read anything that proves
        these actually works, but if anyone has had good luck with
        them I'd certainly be willing to give it a try.

    2.  Do any of your museum security pals use battery powered
        motion detectors in exhibits? Do they make ones that use
        beam technology or have a narrow cone of detection? I'm
        using some little Radio Shack screamers. They're ok, but I'd
        love to have something that's fairly inexpensive and
        portable.
