A Plague of Moths

I have a moth problem. They're everywhere in my house. I go into the bathroom, they're fluttering around the lights. Go downstairs, they're battering themselves against the windows. I probably kill around 5 a day, their scaley residues are smeared all over the place. I recently discovered where they're all coming from. Cleaning up aeround the house I pushed back an old couch and noticed alota dead moths all over the place. I peered around and noticed a hole in the backing. I got a flashlight and looked inside.
What followed was one of those moments when you realize you're in the wrong place at the wrong time. They were living inside the couch, eating it's innards and reproducing. They're silvery bodies crawled over each other as the light disturbed them, I half expected some sorta Mothra queen mother moth to start screeeching at me or something and go for my neck. Not pleasant at all. But at least I know where they're all coming from....
