Dergall does not use any active ingredients and it acts through a physical mode of action. When applied, it creates a three-dimensional, air-permeable net, that tightly surrounds the pest and immobilises them, making them unable to move and feed.
Quick and even spreading of properly prepared solution, helps the precise distribution on the parasite’s body. All developmental stages of the ectoparasites are tightly covered and immobilized.
External immobilization is a forward thinking solution for the pest management in poultry houses as pests cannot develop resistance to physical control.
