Have you done any painting,staining type work recently?

Nope. No painting, no staining. Well, I painted in November but that's not particularly recent. It seems to be concentrating in my upstairs bathroom, which makes me think I should call a plumber. (Still doesn't smell like gas, though.)

I think it would be a very good idea for you to call in an HVAC professional. If there is any problem with your furnace venting, you want to know immediately.

Just a reminder, CO is colorless, odorless and deadly. Better to have the furnace checked out.

Wimsey 70 If you can read my post did you every find out, about the aerosol scent that you were smelling came from, If you did, could you please let me know, yes in 2007 -20014 i used to smell a fishy like smell like cat litter type of smell in the air. Now just about a month ago, I am beginning to smell this strong aerosol toxic fumes smell air all around my house, i would appreciate if you could let me are someone on this post to know, if you found out where the smell is coming from.

I recently started smelling this outside of my house in 2019!

The past couple of days, it smelled like hairspray in my first floor bathroom. I thought my daughters might have been playing with an old can from under the sink but they swear they haven’t. Has anybody figured this out??

Any responds on the hairspray smell outside of house...I live in northern mich and just the last month or so I can smell the hint of hairspray...not every day but often enough to notice and only when the windows are open...I see others are experiencing the same through the last couple years and this is first time it has been happening here 🤷‍♀️🤷‍♀️

I am house/dog sitting and after immediatey arriving I asked if anyone else smelled hairspray? No one else smells it but I have been here for 2 days now and it seems to be getting stronger for me. I am kinda nervous about being here with the smell (and there are 2 dogs). Has anyone gotten an answer to what this smell may be?

Locate and smell plastic storage containers or other plastic objects that may off-gass fumes. If the plastic feels oily, it is likely off-gassing. I trashed over $100 of clear storage bins from a major retailer due to the odor. The odor increased over several weeks when the windows were closed until I could no longer tolerate it.
