Obviously there are different species of dust mites, but the ones I'm familiar with are nearly invincible. They are able to cling onto smooth surfaces even with a vacuum cleaner right over them. I've noticed that they are 'directional' in their grip though: when the vacuum cleaner is behind their direction of travel, they'll hold fast, but if you move the vacuum in front of them they'll be sucked up. Thus, drawing the vacuum nozzle back and forth repeatedly seems to me to be essential for reliably getting rid of them.

As for UV, I have no idea. They seem to survive on surfaces that get exposed to sunlight though windows, but apparently glass blocks most UV radiation. You'll have to make a new post with your results if you try it :)
