Entomology (Study of Bugs)/Small white things in one bedroom
QUESTION: My daughter has these (no more than 20), hanging from edge of walls. Will vacuuming keep them from returning and what are they?
I can't see them clearly enough to be certain but these may be plaster bagworms, a type of clothes moth. They are harmless. Try removing them and see if more return which may indicate a nearby infestation. Post a follow up if this occurs (and a closer photo).

QUESTION: I have added new pics, hope it is a better view for you, we removed them, but they are coming back. How do we eliminate them?
Yes, they do look like plaster bagworms. General cleaning is the best way to manage these insects since there is no "source" that can be eliminated. Again they are not harmful so I'd just clean and pay particular attention to anywhere that accumulates spider webs since these insects are sometimes associated with these webs (they eat spider silk).
