Intervention??? INTERVENTION????
What's wrong with liking cartoons and sci-fi? I allready KNOW I'm a geek, so I might as well live up to it.

And Dent is correct, Aliens take on the characteristics of the hosts they breed from, and they are a bio engineered species (the thing in the ship in the first movie was a member of the species that created the Aliens, they would wipe out EVERYTHING)

However, Predators prepare based on the nature of the hunt, if, say, Earth became infested and a gigantic super queen nested somewhere beneath the surface, the Predators WOULD use a weapon of mass destruction to clear the surface, then move a squad of hunters in to track down the queen.

And we haven't even STARTED discussing human Berserker Teams, super elite, super secret squads of human warriors whose sole purpose is to infitrate a nest, deposit a berserker, and fall back before the carnage starts. Berserkers are the shattered remains of a human, wired into a highly armored, small nuclear payload carrying, acid resitant body armor, which constantly pumps them full of various drugs and stimulants once activated (including Alien Royal jelly, perhaps the most powerful drug in this fictional future univers).. by the time the berserker is done, the suit is trash, but there aren't any, I repeat ANY Aliens left alive.
