Hello, Mr. Davison:|
Miller moths are really a difficult proposition. They will get in the tiniest
cracks. We don't have the problem here in the east, but my brother has recently moved to Montana and
he wrote me about them also.
Insecticides are a waste of time and money, and overkill for a nuisance
pest such as this. You have been doing what is best. Make sure your house is sealed up as tight as
possible, of course. Using your vacuum and those yellow bug lights inside and setting up florescent lights
on the outside, with the sapy water trick is the best idea. Be sure to use florescent lights with the
soapy water, they have a spike in the spectrum that the insects are attracted to. Place them AWAY from
the house, if you can, because you don't want them near the house. Any outside lights should shine on
the house from a location AWAY from the house.
That's just about it! One of the bugs you can
do very little about. Every region has a few of these pesky bugs, some more than others. Weather does
have a lot to do with it, it seems that wet springs have the most effect on the miller moth populations.
Sorry I can't be of more help!
