I noticed recently that there are a few tiny bugs crawling around my laptop. And I seen it on a few other places like around my aquarium tank and my piano keyboard. They are about slightly larger than a grain of salt and sort of a off white color. Sometimes it crawls on the monitor then crawls and hide somewhere inside the keyboard, they move fairly quick. I rarely eat while using my laptop and I clean it regularly with a vacuum. Tried looking online but can't identify what kind of bug it is. Thanks.
