Dermanyssus Gallinae  pose a serious danger to birds. The biggest problem for the breeder in cage birds is the breeding time. Stressed male birds have low libido as well as low semen yield.  Although there are many options to be applied in the treatment, frequent repetition of the application affects the birds negatively. Carbamate insecticides used in the production season can pass into the eggs. Mite infestation was detected in 15 canaries with constant itching and restlessness during the breeding season. 2 weeks after the application of Selamectin, a serious decrease was observed in the complaints. It is predicted that the use of selamectin will be effective against the problem of Dermanyssus gallinae that can be seen in cage birds.
