Mike, you raise some valid questions. I only became interested in this after reading a BeeL post by Bill Ruzicka [log in to unmask] last March 27. Bill is a fairly large and very successfull beekeeper. Seeing I had the time now, I thought it a good idea to do some research. I have not used Glade, but for now I will keep an open mind.

At http://www.cdpr.ca.gov/docs/mee/2001-47mee.htm I found the following information:
191551 - (4822 - 293)
S.C. JOHNSON & SON, INC.
GLADE AIR SANITIZER
USE: DISINFECTANT - FOR THE CONTROL OF BACTERIA, ODORS, SMOKE AND MILDEW
TYPE: SECTION 3 LABEL AMENDMENT - TO ADD A CLAIM FOR CONTROL OF "GERMS"
ACTIVE INGREDIENT(S):
TRIETHYLENE GLYCOL
CAS NUMBER(S): 112-27-6 

Also here two excerpts from: http://www.nicnas.gov.au/PUBLICATIONS/CAR/NEW/NA/NASUMMR/NA0800SR/na817.asp :
"of very low acute oral toxicity and low acute dermal toxicity"

Mike, you asked about the persistance, here is an indication I think;

"Due to the rapid biodegradation of the chemical, it was not possible to generate ecotoxicity......"

Best to read the whole page though.

I am not trying to establish any absolutes. I'am simply interested to get as much imformation as possible to see where Glade fits into the picture:  nothing  in the hive > a ounce a year 1 second puff of Glade > 40 days of Apistan > 40 days of Checkmite. I know Apistan and Checkmite are approved, but then again Bayer's billions can get (almost) anything approved!

Cheers, Bob
