I seem to remember a certain species of cockroach that
was quite fond of
wire insulation...
I really doubt that, sincd cockroaches eat human food. (Termites, maybe?)
My brother usta work in an abandoned building. His screen went funny, and
he looked down -- a rat large enough to require a driver's license was
gnawing on the cable. (This was over 10 years ago, just to _pretend_ to
keep this on topic).
