The fly repellent block is an innovative solution designed to protect animals against the negative impact of flies, bees and animal flies. Regular exposure of animals to these insects can lead to irritation, stress and reduced meat and milk production. Our block has been created using a special repellent formula that effectively keeps flies away from animals. The organic and inorganic mixture is fully metabolized by combining with animal secretions such as sweat, tears, mucus, saliva, feces and urine. This provides comprehensive protection against flies. It is worth emphasizing that the block does not kill flies, but only deters them from approaching animals. Regular consumption of the block helps to reduce animals' interest in unstable substances because it effectively satisfies their appetite. Additionally, natural aromas arouse the animals' appetite. Analytical ingredients include sodium, magnesium, sulfur and do not contain calcium and phosphorus.
