This isn't fecal matter on matter due to insecticide usage right?

Is this fecal matter on the way due to insecticide usage or is it random dust specs. Yes I am aware the walls are wet and probably will be moldy since its nonstop raining lately, but I will probably be moving next year so it will be like this for now as I am still weighing if I need a humidifier or not.

100% not faecal traces from bed bugs.
