In my wall I having small type insect white colour, it's look very small. In my wall I have a lot until my wall also look spot marks.

The two main possibilities would be termites or aphids. Is there any mold or mildew present for aphids to feed on?

Its not termites or aphids.
The insect smaller then that, it just look like a dust, when watch deeply the thing moving.
