Abstract : The hygiene of beehives is of the utmost importance for the protection of the health of bees and bee products. Disinfection is a very important hygienic measure that is carried out in order to prevent and suppress infectious diseases of bees and contamination of honey and other bee products with harmful microorganisms. The disinfection procedure is very complex, and its efficiency depends on a large number of factors. In beekeeping, as well as in other branches of animal husbandry, preventive, liquid and final disinfection is carried out. During the disinfection, the following factors must be taken into account: the spectrum of action of the disinfectant, the method of application, the concentration of the disinfectant, the exposure time, the properties of the environment to be disinfected. The active substances of disinfectants usually affect the metabolism of microorganisms. For disinfection in beekeeping can be used: chlorine preparations, iodine preparations, bases, acids, quaternary ammonium compounds, aldehydes (glutaraldehyde, glyoxal), oxidizing agents (hydrogen peroxide, acetic acid). There is no ideal disinfectant. Due to the toxicity and other harmful effects of disinfectants, and often their insufficient efficiency, preference should be given to physical methods of disinfection, whenever possible. Chemical disinfection is often not successful, especially when it comes to the causative agents of American bee brood plague, which form very resistant spores. In that case, the only way is to burn the hives, so that they are not a source of infection. Against the spores of Paenibacillus larvae, the most effective chemical disinfectants are chlorine preparations, warm solution of sodium hydroxide, oxidizing agents, therefore, these disinfectants are most often used in beekeeping. However, the negative properties of these disinfectants should also be taken into account.
