Thanks for your question. By "Miller Moth", you are probably referring to Euxoa
auxiliaris,
also known as the Army Cutworm Moth. The Miller Moth term can sometimes be applied to any moth that gets in one's home.

Those moths, and most nocturnal moths, are attracted to the same frequencies. They are most drawn to the upper part of the UV spectrum, just below visible light. In the visible light spectrum, they are most drawn to blue and violet. Some vendors, such as BioQuip, even sell special lights that focus on these frequencies and spectrums. Ordinary bulbs inside and outside of homes contain some of these frequencies, so that although they do not look overly blue/violet, these lights are still are seen by moths.

Euxoa auxiliaris is unusual among most moths in its habits. They are very sensitive to both cold and bright light (i.e. sunlight), so try especially hard to hide from sun and find cooler areas during the day. That's why they often end up indoors.

I hope this information has been helpful to you. Thank you for requesting the information.
