Mystery dead fish smell??
We have been plagued by a mysterious "dead fish" smell in our house on and off for about 4 weeks.
We are baffled. There is one spot in our den where you can smell it terribly. But, it comes and goes. Maybe twice a day, maybe twice a week.
My husband checked the attic and found nothing. Tipped over all the furniture and everything is in tact (no signs of chewing/destruction).
The smell is near the fireplace, but when we open the fireplace and smell--it doesn't seem to be coming from there.
If something died, theoretically it would smell for a while (like "death") and then go away, right? This smell is not the typical "death" smell, but dead fish, and it keeps coming and going. Any ideas?
