Hi all,
Formic acid, I use it! But CAUTION,PLEASE, you must add ACID TO WATER not the
reverse, if you add water to dilute then explosions sometimes occur, like when
there is lime in your water.
 
You can use a cloth on a saucer to evaporate acid from below the brood at 85%
or from above at 65% and as you were advised previously temperature is
critical, there are many evaporats available from Europe which are very
effective, I use those made by Weinold in Berlin from a design of Herr Becker
which was tested at the  Berlin Free University Frau Dr. Eva Rademacher, Prof B
Schricker and B Polanski, I have translated their published work which you can
get by emailing me direct. [log in to unmask]
 
You can also pick up the Swiss webpage from Apiservices.com  German language
webpage, the Swiss page is in german, but should be available in Italian swiss,
French swiss or even Romande.
 
Used carefully and safely, formic acid is effective and cheap!!
 
Best wishes
 
Peter Hutton
