The epidemiological and epizootic importance of ticks has been known for a few decades since of the
discovery of their role as vectors of many new diseases, and the better detection of those already known. Given the
durability of chemical preparations in the environment and the increasing problem of developing tick resistance, natural
strategies for biological control are sought. A promising alternative to chemical pesticides is the use of
entomopathogenic organisms for effective integrated pest management of low environmental impact. A number of
promising microbes have been identified during the search for effective means of controlling the tick population, but
the knowledge about the impact of these pathogens on the environment and other non-target organisms is still
insufficient. Previous research has still not provided a definite answer about the safety of their use. It is known, however,
that the chemicals which are currently used have a negative impact on the environment and/or cause resistance. No
efficient biocompound has yet been devised for commercial use. Potential microorganisms for tick biocontrol (mainly
bacteria and fungi) are natural tick pathogens, living in the same environment. With their adhesive properties, and their
ability to digest the cuticle, they may constitute an appropriate ingredient of bioacaricides. Until now, fungal insecticides
have been used only to control crop pests
