Hmmmm. I'll add to Eric Metzler's off-the-cuff comments. First of all, why
are these moths referred to as Millers? Sounds like they might be able to
bore into wood as larvae. Secondly, and this is just an extension of the
first point, is there any reason to question whether they are in fact
entering as larvae and pupating indoors? My problem with the idea that the
moth is squeezing indoors as an adult is that this doesn't seem to fit their
design (relatively flat as they may be). Still, if they really wanted to
get in, they wouldn't need much of an opening.
Now would be a good time for someone with some real insight to step in...
