Here's a weird thing: Every winter, as soon as the rain starts, one of our bedrooms starts to smell like rotting oranges. It only happens when the weather is cold and wet, which immediately makes one think of mildew, but it's not a mildewy smell at all -- it has a definite citrus smell to it, very tangy.
It's elusive, too; we've tried to find the source with our noses, but no luck.
There's no mildew in the closet, or in the rest of the room; I dread pulling up the carpet to see what may be growing under there, or opening up the walls, but it looks like I might have to.
So, before I start the demolition, does this sound like ANYTHING ya'll have heard of?
