If I recall correctly, the Director states that the monsters were given to the Organization by the Ancient Ones, which implies that the Ancient Ones either created the monsters or have some way to control or influence them. If that's the case, then it makes sense that the monsters only go after humans; the Ancient Ones want to humanity to suffer, so that desire is reflected in the actions of the monsters.
