Think Fuddy's suggestion of borrowing a dog is a good one.

Any chance you have a dog food bag or similar stored in there somewhere?

Is your lawnmower in there?...fermenting grass under the deck?

You might have phantosmia, a condition where you smell things that aren't there. I'm pretty sure I have it because I often smell smoke that isn't there.

Could it be mildew from a roof or wall leak? Maybe something in storage like a paint can that has rusted through and is leaking.

May not be relevent but I'll post it anyway.
Many years ago I stupidly used a T-shirt I had left in the car to wipe the inside of the rear window. The glass was a bit foggy, I still smoked then, and it just seemed (at the time) like a handy thing to use. The next day I couldn't believe the smell! It was like I had three sweaty construction workers riding with me everywhere I went. I used Windex and paper towels several times for days afterward, but the smell still lingered. I was quite a while before it went away.
Have you left a undershirt or something like that in your shop?

Probably a result of all the figs you’ve been eating;)
