I began sniffing around in hopes of discovering the offender; to no avail. But, I had things to do, I couldn't be bothered with this pesky possibly-growth-stunting-chemical invasion of my house... I went downstairs into my room to work on high importance level project. I still noticed the smell, but didn't think much of it; I was busy.
Moments later my roommate came downstairs. She was concerned. The smell was apparently getting stronger upstairs... she was right. It was outright loud.
Like a true hero, I put my project on hold and I began a full fledged investigation upstairs.
Here were my findings:
Yesterday there was a minor ant invasion. We had sprayed. Could this smell be lingering ant spray? Seems unlikely, but as a true detective would, I took into account exterior factors: the oven was on; heat thus exacerbating the odor of the once stale ant spray. Furthermore, the spray had sat all day; thus could have germinated. Must just be the ant spray.
Returning to my room, I discover my room may actually be the vector. Eeek. Surveying my room, I decide to throw out my trash. I walk out to our shared garage space to the trash bin and discover this scene before my eyes:
Next door neighbor refinishing the garage floor at midnight. Nice. Buckets of lacquer and paint. He casually comments, "I bought the quick-dry stuff, the smell should be gone in about 5 hours." Translation: "This large bucket of poly-blah-blah has extra smelling chemicals in it and by morning you should be completely high. Hope your dreams trip you out tonight. Sleep well sucka".
