It does not go so.The only time I would consider side insulation is for a Nuc where the cluster is small.
Yes, we all know Thymol is toxic full on, but so is a bottle of aspirin. I assume the Apiguard delivery method and the dosage % against volumes of product must be so weak that any toxicity is rendered negligible! It is easy to be curt, why not ring Vita,for whom the product is maufactured in Europe, yourself? I am only repeating what I was told by the head of R & D....look at the contact list on the web site http://www.vita-europe.com/. You will see the cleaner's details there with Dr as his title!Thymol not toxic in any way,you must of been speaking to the cleaner.
'covering their *rse' perhaps?From that research it seems its okay to use thymol in the hives all year round if needed,does not make any difference if the supers are on the hives or not.So why do the apiguard instructions say not to use when supers are on,yet a 0 withdrawal period for honey,kind of a contradiction.
