Our suggestion is the repellent net
With this proposal, we can cover the air shafts and recesses. The placement of the net is done in a way that makes it visible only from a few meters away. The net is made from polyethylene so it is not able to be destroyed by the sunlight.
The repellent system has certain characteristics:
» It is harmless
» It is effective in all cases regardless of the attack’s size of intensity
» It is permanent and does not need maintenance
