The Material Safety Data Sheet for Lysol(r) All-purpose Professional Cleaner (http://www.hescoinc.com/msds/ly74392.pdf <http://www.hescoinc.com/msds/ly74392.pdf> ) shows concentrations of quats over 3%. I have seen it for about $5 for a 22-ounce bottle online.

It has procedures from March. The supposedly final June versions are here: <http://www.fws.gov/northeast/wnscavers.html>. Note that in several places these new documents state that quaternary ammonium compounds with a concentration of >3% should be used. According to people I have spoken with, that is incorrect. It should state 0.3%. This is actually what the second USFWS document says in the table on page 5, in contradiction to what it says on pages 2 and 3 of the same document. This is very unfortunate. It is actually difficult to find these compounds in concentrations as high as 3%. Mark Minton
