I've recently had a problem with mold/dust/PC mites in my room, and I find a couple on the outside of my PC ever so often. I also see a few inside on the ceiling of my case, but none on the actual components of the PC (GPU, MOBO, CPU, etc), or at least I can't see them. I wipe any off that I see, but I'm not home all the time because of work and school so I want to know if this little pests will harm my PC in the long run, and also if anyone knows of any repellent that works well. Thanks!
