Stealth Carpet Beetles

Posted by Neil Radisch on June 28, 2000 at 08:55:39:

What can be done if the source of the infestation
is not apparent? I find about a dozen of the
beetles every day, but they seem to just appear
out of mid air. Is it possible for these things
to be breeding in the walls? We had rats in
the walls the year before I saw the beetles, and
though the rats are gone, I wonder if they're breeding
on a rat carcass, or droppings or something.

HELP!!!!
