Hi, am not looking to buy but keen to know how to self-dismantle the bi-fold door? any advice?

Does any one know how to dismantle the HDB BTO bi-folding door located at between the kitchen and the service yard? The dismantling is only for the door, not the frame, and should be able to re-install it if required to at later time. A step by step instruction is much appreciated.

Recently I found this tiny crawler on the walls and ceiling of my unit which is barely 1 year after moving in. These crawlers are scattered and are so tiny they are easily missed. As my walls are painted white, they became slightly more obvious when they moved and I managed to take a close up photo of one of them. Can someone help to advise what are they and how to rid them for good? Many Thanks!
