Beekeeping is a sector that in many countries serves as a source of employment, income and a way to protect and preserve health. The Republic of Croatia has favorable conditions for beekeeping and is traditionally a well-known country in the beekeeping sector, but it still does not sufficiently use all its potentials in this activity. The beekeeper is engaged in beekeeping, and every beekeeper must comply with certain legal regulations and norms. Accordingly, a number of associations and communities headed by the Croatian Beekeepers' Association operate in this country. In the beekeeping business, it is necessary to regularly and properly maintain the health of bees, cleanliness and safety of their hives, but also the environment. Every bee is susceptible to some diseases and the most important thing is that the beekeeper recognizes the disease in time and cures the bee. Because bees live in communities, the infectious disease spreads very quickly and easily to other bees. Various treatment methods are used for this purpose, depending on the severity of the infection, the type of bee and the like. However, beekeeping is not a simple activity at all, but it is certainly not used to the maximum in the Republic of Croatia, which is really a pity.
