Question: I think I have identified my bug problem, but want to make sure  I'm correct.  Are there indian meal moths in PA? I really noticed them flying in the house tonight It appears as if they are a red color under their wings. They cling to light. I see them during the day near my plants & climbing the sunlight filled windows.
