Are you really sure about this? The temperature of the interstellar medium is probably just a few degrees above O deg K, even near the galactic center (unless you're near a star or supermassive black hole.)
The galaxy is mostly very cold hydrogen, even near the center.

Also, against the background of intergalactic space they would stick out like a sore thumb due to their waste heat IR emission. We would have spotted them by now, as soon as IRAS flew. Not to mention, if they have enemies, there's nothing to hide behind out there.
