According to current legislation, the farm area should be fenced. The fence itself should prevent or make it very difficult for wild animals, dogs, cats and rodents to enter the farm.
In the case of the latter, this is quite difficult in practice. The introduction of companion animals (dogs, cats) should be prohibited on the farm. In order to minimise the entry of rodents, vegetation on the farm should be systematically cut back. Specialist poison stations have mechanisms in place to count the number of visits so that the effectiveness of control of these pests can be assessed. It is also necessary to check whether there are any so-called signs of rodent habitation (droppings on surfaces, burrows, dirt on walls, physical presence, etc.).
