Not only is use of Coumaphos a problem over time, contamination of new
foundation made from old wax is increasing.
I can't say I've seen any of these problems, but then most of my comb is
new, I don't use coumaphos, and I use plastic foundation (originally due to
it's other benifits).

What do the big beekeepers use?  Do most use the big commercial drugs?  Do
any use IPM and alternate treatments? (FGMO, formic acid, mite solution/bee
calmer, wintergreen oil or other)  I see many different things used
successfully by small beekeepers, but I understand some are probably just
impractical for larger operations (like fogging hives every week)
