The intensification of the hunting industry leads to an increase in the number of animals and creates conditions for the spread of invasions, incl. helminthic. The transboundary position of the Western regions of Ukraine contributes to the expansion of the species composition and habitats of helminths, which in the current climate change can complicate the epizootic situation of dangerous invasions. On the basis of the literature and the results of our own research, potential risks to the hunting economy for the emergence of new helminthiasis caused by the species-species have been identified. In the work the influence on the helminth fauna of ungulates, kept under conditions in the aviary, modifying and regulating environmental factors, is analyzed. The modern changes in the phenology and ontogeny of pathogens of mass infestations, first of all in geo-helminths, have been investigated. For the causative agent of dictiocaulosis, prolongation of the seasonality of invasion by larvae has been established. It is shown that the decrease in the extent and intensity of invasion of individual trematodes correlates with the dynamics of their intermediate hosts. The data on the effectiveness of remediation with aqueous solutions of polyhexamethyleneguanidine chloride, landing sites were obtained by decontamination of soil in wildlife clusters, in order to minimize their infestation by nematode larvae. The proposed remedy is an organic compound, does not scare away animals, but by contacting organic and inorganic constituents of the soil and lose their potential toxicity. Efficiency of destruction of larvae of Strongylid and Strongylate in the sample ranged from 78 % to 87 %, and in the surface (up to 5 cm) soil layers – 96–100 %. Research findings should be reflected in planned antiparasitic measures.
