Economical 5 L oral biostimulant to support multiple hives through critical periods of stress and transition.
Five litres will see a mid-sized apiary through the season. What they will not do is treat anything.
BeeVirol® in a 5-litre container: an oral biostimulant solution for bees, within the nutritional management of the colony. It is the commercial format — at the maker's dose, one container covers between twenty and thirty-three hives.
01 · WHAT IT IS AND WHAT IT IS NOT
It is a nutritional supplement, not a veterinary medicine. It does not treat or prevent disease, and it replaces neither an authorised treatment nor a vet's diagnosis.
And one point deserves to be blunt: American foulbrood and European foulbrood are notifiable diseases. On suspicion — sunken brood, the characteristic smell, perforated cappings — what is called for is notifying the official veterinary services, who diagnose and decide the measures. No supplement enters that conversation.
02 · THE ARITHMETIC OF THE FORMAT
The maker's dose is 150 to 250 ml per hive, so five litres work out at between 20 and 33 hives per container, depending on how much you use.
Below that figure the 1-litre format is the one that suits: shelf life is 24 months and it keeps between 0 and 25 °C somewhere dry and ventilated, but a container left open half a season is not a better buy for being cheaper by the litre.
03 · HOW IT IS GIVEN
Sprayed directly onto frames and bees; in syrup, mixing that same amount into each litre of liquid feed; or worked into winter paste, in the same proportion per hive. The maker places it above all after the harvest and as an autumn boost.
The usual caution with anything applied inside a hive: never with honey supers on.
04 · WHAT IS IN IT
The maker declares quaternary benzyl amine, propolis, maltol and cobalt chloride. It is a whitish-yellow liquid with a characteristic smell, and the product is declared GMO-free.
It is made by SC CIRAST SRL in Romania. If you work with certified honey or under production rules that limit inputs, go over that composition with your certifier before using it.
05 · BEFORE YOU BUY

| ✓ FITS | Operations applying it to more than twenty hives in the same season. |
| ✕ DOESN'T FIT | Treating a disease: that is an authorised veterinary medicine. |
