Janice:
There's one thing I must mention in conjunction with aromatic woods and
small mammals: I have read, more than once, that aromatic woods can give
off gasses ("out gassing") that can harm small mammals.  This is why most
who know anything about it, don't use cedar chips in critter cages.
There is some controversy about it, but it goes to figure that, if it is
strong enough for a person to smell, it may be too strong for critters.
Why do you think they use it in clothing storage containers?  It repels
moths with it's odor.  Just something to be aware of.
 
As for moth balls, we used to use them in Texas to kill fire ants.  Just
one moth ball, shoved into a large, healthy fire ant mound, will kill it
completely overnight!
 
That's interesting about using the R/C car in the attic.  It would
probably take one larger than the one I have, but they now make them
big enough for a small child to ride. :o)
 
They make and sell, in alarm supply houses, a "Wrist Rocket" slingshot
with a Zebco fishing reel attached to the handle, just for getting wires
across attics.  To date, that's about the best way to do it.
 
But, when it comes to ferrets doing the job, one thing just came to mind:
fiberglass insulation.  I don't think that would be too good for any
animal (although mice and rats seem to thrive in it).  I certainly
wouldn't want to expose *mine* to any insulation.
