Replying to Small blue shit on my sink

This is a terrible place to ask this question but...

In the bathroom in my apartment (which has terrible ventilation and is always muggy), I have to clean the surfaces in my bathroom every week or so because these little strands that look like tiny blue hairs, about .5 mm long cover everything. What the fuck is this shit? its probably some type of mold but i was hoping some of you domestic ass fools had any knowledge about these tiny pubes growing everywhere. just curious to what it is.
