Summer Vaporising with supers present

[The Poot]

Hi, do any of you use "Hiveclean" for Summer varroa treatment? If so, have you had good results? I think it has OA as part of the concoction.

I think it's no longer available because Apibioxal has been registered as the only oxalic acid treatment which can be legally used
If it did reappear for sale it would be without any oxalic content

If you have taken your honey and supers off then Thymol which could be Apilife Var or Apiguard is a good Summer option
The treatment period is quite long and so covers the Varroa reproductive cycle if you follow the instructions
The kill rate would be at least 70% probably more
(Thymol was another main constituent of Hiveclean)

From some of the reports I have read, hiveclean was not that effective..
This time of year is difficult as varroa numbers are increasing - perhaps to dangerous levels - but if the supers are still on the hive, treating for varroa is difficult.
