Influence of treatment of cattle with synthetic pyrethroids on the number of insects in their activity areas

Blood-sucking dipteran insects (mosquitoes, black flies, horse flies, and biting midges), commonly known as gnat, cause significant disturbance to farm animals during the summer grazing period, which negatively affects their health and productivity. Nowadays, treating the skin with insecticidal preparations to protect animals from gnat has become widespread. This provides comprehensive protection for animals due to the irritant-repellent effect of the insecticides used, as well as the death of insects upon contact with the treated hair, which is accompanied by a decrease in the total number of gnats on pastures.
