An important factor in the infestation of a house is its proximity to a forest and generally to places where there are nests of wood-eating ants, another important factor is the humidity of the wood, as these insects want wood with a relative humidity of more than 15%.
These insects always come from outside, in many ways such as from wiring, from tree branches in contact with the roof, from firewood
Wood -eating ants create nests at a distance of up to 90 meters from the parent.
