Problem with Scales

I have a question for some experienced growers out there, I currently have an active battle I'm fighting, thought I was done after my last tour in Iraq lol. Scales have found their way into my room and they seem to like their new home. I have heard that if you used a 50/50 alcohol/ water or, or even stronger on "veg" and I say again "veg" plants only it will kill the scales. They do not seem to be doing much damage as I squish them when I see them however, I would like them nuked.

Thank you,
