Vaseline is petroleum jelly...it will kill the mites. Change all the bedding and dust the brooder well with DE or mite powder bought from the feed store. Then you can bring them back inside.
Mites do not affect humans but clean your room well and vacuum. You could spread the mite powder on the carpet (if you have it), let it sit a bit and then vacuum.
