1.3.3 Oxalic acid evaporation

Oxalic acid is harmful to health. Vapours or dusts of this acid must not be inhaled or come into contact with the skin. It must be handled with the greatest caution. In all cases, protective goggles, acid-resistant rubber gloves, an FFP3 protective mask and long-sleeved clothing must be worn.

During treatment, make sure not to stand in the oxalic acid cloud. Colonies must be treated from the outside (not inside the bee house). As it is impossible to completely avoid contact with the vapours, we recommend wearing a half mask or a full-face mask equipped with an activated charcoal filter. This provides effective protection. Attention: filters have an expiry date and must always be stored in a sealed plastic bag.
