Unscrew or Wiggle Out Anchors

For screw-in plastic anchors, simply use a screwdriver to back the anchor out counter-clockwise. For expansion anchors (that spread behind the wall), first remove the screw. Then, try gripping the anchor's lip with needle-nose pliers and gently wiggling and pulling it straight out. If it resists, you may need to push it slightly into the wall or carefully cut the lip flush with the wall and spackle over it.
