Bill: Look I appreciate your POV but the paper quoted is quite intensive for reading and goes into great detail on the photodegradation process on all aspects of fluvalinate and I talked it over in great detail with Jerry Hayes when he was with Dadant on getting the fluvalinate out of beeswax, even to the usage of special lights when I wrote the actual chapters in "The Way Back to Biological Beekeeping" (free book, posted at beesource.com). It is a paper used by the chemical companies producing fluvalinate, and is restricted reading for just outright usage/field without permission. The penetration of sunlight with the wax is not very deep like only about 1/8 inch would be a lot and 1/16 would probably be closer to the actual breaking down, and this is just not done in solar wax melters. You'd get better breakdown of the fluvalinate, throwing the waxed frames out in sunlight for the cell walls to face the sun themselves when empty, then in a solar wax melter.But remember to flip them over to photodegradate the other side with the sun the following day or so. Perhaps you should try to request a copy of the paper if you can and read it. Respectfully submitted, Dee A.
