Antifer – solution is used with an absorbent material by the means of evaporation. Apply the product e.g. by dripping it on a cloth or cellulose, placed in a perforated plastic bag or on carpet strips of approximately 10 x 30 cm, and hang it on posts at the height of 50-100 cm and 20-50 m apart on the perimeter of the protected area. The product is effective for a period of 14 - 21 days, depending on the weather. After this time, it is suitable to use a different variant of the three manufactured products (Antifer Red, Antifer Green, Antifer Blue) - each of them contains a different ratio of fatty acids (different odour). In this way you will prevent the wild animals from getting used to one type of odour. One set of Antifer 3*1,000 ml products is able to protect for at least one month an area of 50 - 80 ha or length of3 km, depending on the terrain roughness.
