Think of them as the Storm Troopers who hunt out easy prey and raze Jakku in the Star Wars epic The Force Awakens. Or the hulking Orcs who obliterate everything in their path in Lord of the Rings. Or the Dementors who suck the life and soul from the good hearted in Harry Potter.
You get the picture. They're nasty.
But it need not be apocalyptic. You can repel them, or in the least mitigate damage by observing five basic tips.
