> > >I used Apiguard and it did its job, but the lingering smell..... Oddly, that's not something that we notice. Perhaps due to our different climate. I'm curious as to the mechanism of how the thymol got into your combs. Thymol evaporates very slowly. Since Apiguard is applied in a pan or on a card, the granules must be carried by the bees for removal from the hive. I'll see whether I can track its distribution this summer, using a fluorescent tracer. -- Randy Oliver Grass Valley, CA www.ScientificBeekeeping.com *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
