You just mix up some pollen, sugar and water, and whatever active ingredient you want to put in, and you just give it right to the bees. No chemicals involved, just immune boosters.
Amesteci polen, zahăr, apă şi orice ingredient activ doriţi să adăugaţi şi îl dai direct albinelor. Fără chimicale, doar stimulatori de imunitate.
