Surely as these bugs are monitored by a normal FM radio, all you
have to do is to turn on your own FM radio in the house and go through all
the frequencies until you hear feedback. at this point you know the
frequency of the bug. I assume you could also use a radio to then detect
the exact location of the bug.
