   It is just possible to see a dust mite under a magnifying glass, when the subject is well lit and placed on a black background. A typical house dust mite measures 420 µm in length and 250 to 320 µm in width.

   you really can’t see dust mites, that’s why it’s a good idea to vacuum your mattress often.

   House dust mites, due to their very small size (250 to 300 microns in length) and translucent bodies, are not visible to the unaided eye. For accurate identification, one needs at least 10X magnification.

   Microscopic. They actually don’t harm you, unless you are allergic.
