You knew those three things would be combined in a headline one day, didn't you? I've been thinking about this lately because my house is plagued in the summer months by pantry moths. They seem to arrive in foodstuffs, though I've never been able to pin down the exact source. In any case, they arrive in Spring and try to live with me until Autumn. (However, I have a BugZooka so the moths end up living outside after I catch and release them.)
