Does anyone else have brown moths on their windows in their pole barn? I just vacuumed up around 20 under each window. They are dark brown about an inch long. What are they, and how do I get rid of them? I will try to get a picture later.
Do you have any grain or cereal products in your building? Bird seed?
You might have an infestation of Indian Meal Moth
They arrived in my house in a bag of bird seed.
Ended up having to toss everything in the trash: rice, flour, sugar, coffee, tea, cocoa - they get into everything.
IF that's what they are, let your local agricultural people know about it.
