Hi all - just thought I should pass on a really bad error I made last night - and quickly rectified.
Story is this: I have just finished the last Apiguard treatment on my hives and took off the tin trays prior to starting the winter feed as the hives are quite light.
In my ignorance, as there was some Apiguard left on one tray, I though it would be a good idea to add this to the winter feed to give the bees the full treatment.
I would add that what was left was almost like a fine lattice work (held together by something like a spiders web though it clearly wasn't.
Well I boiled up my feed and added the extra (lattice) and instantly there was a very strong odour of Thymol (the main ingredient) OK I thought, this is what was left post treatment so there can't be much so it will be OK to add it.
WRONG!!! it would appear that the thymol is purely there to vapourise and when you take the remainder it is in the pure form and as such is extremely toxic to the bees.
As soon as I put the feeder on and loaded with the mixture several bees came up and were overcome by the feed. Luckily I stayed and watched what was happening so was able to quickly take the contents off and have ditched everything today.
The thymol had crystallised inside the feeder and I was amazed how much there was - sorted by multiple washings of boiling water but the feeder still smells quite strong. And SWMBO is very cross as the pan I boiled up the feed in still stinks of Thymol!!
From what I have seen, the bees take the sugar from the Apiguard but leave the thymol (hence the latticework. I maybe totally wrong but the purpose of this post is to make sure none of my fellow beekeepers make the mistake I did.
Hope this has been helpful.
