Objective of research: studies of the grade of environmental contamination in the objects of outdoor environment - poultry farms by chicken ticks Dermanyssus Gallinae and evaluation of the efficacy of preparation Biorex GH against arachkoentomoses. Materials and methods: 20 scrapes from the objects of outdoor environment (floor, wall surface, passageways etc.) were taken to determine the grade of the poultry farms contamination by infection elements of D.gallinae. The number of ticks including egg, larva, nymph and imago stages, were calculated under a microscope in a Petri dish. Biorex GH concentrate 2,5% (active ingredient - cypermethrin ) was applied for desacarization of the poultry farm during the preparation period at a working concentration 0,005 % by consumption rate 150 ml /1 m2 and exposition within 24 hours. In the final stage of preparation the desacarization was conducted using the same drug concentration by consumption rate 75 ml/ 1 m2. The drug efficacy was determined weekly over the first month, then every two weeks based on the calculation of the amount of ticks in the installed traps. Results and discussion: The 45% infestation of examined samples was reported based on the fact that 3–12 examples D.gallinae was found in one sample. Scrapes from the wall surface were infested by ticks by 40 %, technological equipment - 20 %, passageways - 10 %. The drug efficacy in different terms after treatment was 88,5 and 85,1 %. The treatment with Biorex GH had a positive impact on preservation, productivity and other production and economic parameters.
