To the person who posted the chemical smell problem - I have it too! I am original owner of a 10 year old house, slab on grade (no basement) in South Carolina. Smell started from middle floor of closet. Ripped out carpet, sealed floors, new padding and carpet. The smell "moved". Smell moved to my bedroom floors. Ripped out carpet, sealed floors, new pad and carpet. Smell moved to my bathroom and between door jams. There were no cracks in concrete and no visible water. Its so bad, you can lay a towel down on the floor, wait 5-10 minutes and then pick it up and you would be knocked over by a pesticide smell (smells like you soaked towel in can of Raid). Ive called pesticide division at Clemson and had everyone out here trying to figure out what it is - no one knows. I do NOT have exterior bug spray or termite treatment in years (but Clemson said that's not it because it would disapate - not get worse). None of my neighbors have problems. Smell comes and goes. Tonight it is so bad, you can smell it from the front door (and its raining hard outside. Anyone have any ideas? (and its not a dead animal - its been getting worse for the last 4 years, no cracks in floors, no water noted, checked with pest control, contractors, plumbers, electricians - just think about a can of Raid - that's what it smells like). No one comes to visit anymore and some even think I might contact a priest! Please help!

Found this post on a google search... I would love to hear from the poster to see what they found or anyone else. I just bought a house in NC about 2 months ago. Recently getting that "raid" type smell up on my second floor.

Wondering what it could be. I did have Air and Heating come out and to check the refrigerant might be leaking... Nope... Just had the county fire department come out and they couldn't find anything but smelled it also. We do not have carpets its all bamboo (2nd floor and tile 1st floor) Its isolated to one spot in the house and starting to grow in area. Its really strange.

Please email me at angelo.volpe@gmail.com

Thanks

Im original poster.
Had 3 different plumbing companies come out. They all smell it but found nothing. I tore out pieces of drywall around the home (yes - its making me that crazy!) to see if there was a mold issue causing the problem. Nothing.

Not only has it continued to get worse, but it is spreading. Its almost unbearable and we are confined to living upstairs with the windows open.

Any other suggestions would be appreciated

Is there any spray foam insulation in the attic? Almost makes me think there is something synthetic that is outgassing.

Has anyone found the source of the raid smell? We have it outside, I suspected farmers but, have reason to think it is not. I researched for any plants/trees that smell JUST LIKE RAID, nothing. After reading here I am suspecting the septic system and glad our problem is outdoors! How can a septic system smell like raid? Did anyone ever get any answers?

Had a house built 3 years ago and the walk out basement concrete stinks. We thought it was the carpet so tore it out. It wasn't. I smelled the concrete and that's where it's coming from. I'm wondering if the concrete has flyash in it and it's gassing off. I can't even go down there.

I do not have an answer...but i do have the same darn issue. It came up a few days ago. I thought it was Freon but I learned that Freon is odorless. The weird thing is that the smell comes and goes. Two story cape built in 1988 in MA, No HVAC, forced hot water 2 zone furnace in basement, separate water heater. The smell wanders from room to room for random periods of time (several minutes to several hours) and then completely goes away. I have not smelled it in the basement.

I'm posting because I smelled "raid" in the neighborhood a day or so ago.

A Raidy-refrigorator-airconditioner smell is the best I can come up with. The sites I've visited all say "just keep sniffing" but I'm getting dizzy!

Hi...Im the original poster..again. no luck and it gets worse. Thank you to the poster who suggested a dehumidifier. I bought 2 plus 2 high end air purifiers that run 24 hrs a day. Smell comes and foes but some days its unbearable. To the poster that said his was "outside". In another subdivision, workers were digging up pipes and plants at a gated entry to a Country Club and when I went by, I smelled it! Its crazy! Im going to try a Rainbow Machine...companycomes out and uses a charcoal system to clean air...ill let you all know if it works.

Has anyone figured out the source of this odor? Our garage started smelling like pesticide two days ago. We have lived in the house 10 years and never experienced anything like it.

I have the same problem. I just had the fire department out and they can smell it but can't identify where it is coming from. They said that the smell seemed to move and would be strong in one spot and then disappear. The smell was strongest around sewer pipes where they went in to the soil. The smell was very similar to fingernail polish remover or acetone. No body can pin it down. It's crazy. Maybe it's the ghost of a dead bug that I killed with raid! Lol

Hi all, I think I have an answer for you.. My garage started with the nasty smell a couple of weeks ago and I could not find any source, it got so bad I hated going in there as it gave me a headache. The barn was built over 30 years ago with no issues until now. After reading all these posts it got me to wondering if it was the stack of bagged cement left over from a project. It has been there for about 5 years now, covered with a tarp. We took the tarp off and by this afternoon, the smell has gone. So, is there something in the concrete mix itself? Just an observation, I hope it steers you all to a solution, maybe sealing your floors or ?

I was chopping down some mini bamboo today in my backyard in Tulsa, OK and noticed it smells EXACTLY like raid pest control. Anybody who lives by these plants or has bamboo in their house might want to take a closer look at them possibly causing the raid smell. If it isn’t the bamboo itself maybe it’s something that initially grew on the bamboo such as a fungus that’s made itself at “home” in your home.

I just moved into a brand new development and I’m having the same issue. It’s a smoky chemical smell. It’s in all my clothes now too. I can smell it coming from one wall in particular. It’s like fumes coming from the walls. I catch a whiff time to time when walking through the house. The whole hiss and garage has the smell. When I live for trips and return after several days (doors and windows all shut and no ventilation while I’m gone) the smell is horrific! It’s a nauseating smell too. I can taste it in my water if I leave a cup of water out. Management can’t figure it out. I think it’s whatever material they used to make the walls because now that it’s summer it seems that the walls are heating up and releasing more of this smell.

Did anyone found the source. I have the same issue of chemical like smell. It’s also similar to biting oil like. The only place I get is my study room facing outside on 1st floor and garage. Funny that no other room has it with the exception of once when entire house fitnesses it. It was so sharp that I got up from my sleep but after that it’s only in one room. The smell only comes in the morning and disappears. Nearest I have been able to locate outside is at the corner of my patch where I see a big hole dug and once I saw a squirrel come out of it. The size of the hole is big and almost feels like some skunk dig it.

Has anyone figured out what (or where) the bug spray smell might be coming from? I haven't noticed it until today, not until I was walking the property shortly after an afternoon deluge. I thought it might possibly be our sewer backing up because of all the rain today, but it's been super dry for more than a week, so I don't see any reason why it would be backing up. The air has a sweet bug spray smell to it, and it doesn't seem to be any stronger near the drain field than it is in the field behind the barn. It's like it's everywhere. Fortunately, I'm not experiencing the smell inside the house. Not sure if it makes any difference, but our house is 130yrs old with a red granite foundation, and we do NOT have any concrete or cement in the construction except for a four inch layer in the cellar. As for the smell being outside, we do have a cottage-like structure at the back of the property that was originally built to be a garage. Three quarters of the building is constructed from cement block. That being said, there is no smell on the interior of this particular building. I'm completely baffled by this. Before I hire my sewers cleaned, I thought maybe I'd check here to see if anyone figured this phenomenon out.

Having the same problem just started 3 days ago in my apartment complex. Only in one room,manager came over and she said it smelt chemically but can't pen point it. Horrible smell can't stand it. And definitely don't know exactly where it's coming from. And like many others posted it comes and goes.

This whole thing sounds like satans handy work.. everybody complains of the same smell that propegates and subsides at specific times, gets worse when hot out, some smell it outdoors but it still only gets generated in specific areas... makes me think of decomposing material happening below the surface, like radon.. dunno. I got same issue but is not raid smell. Mine is like the breath of somebody after they ate a garlic pill and old milk.. like a odd seawage gas smell.. is bad and wonr fo away either..

I think I finally discovered the issue: poor ventilation from the sewage pipes. As waste decomposes it gives off a gas. The ventilation or layout for these pipes was not done correctly. That is why I smell a rotting sour smell AND a gas smell. It’s the smell of the waste before and after it decomposes. The smell is really strong at the wall right where the pipes are that run from my upstairs neighbors unit down through my unit. The smell from the wall is a strong smoky, gas, chemical like smell and the smell that permeates throughout the house is a sour, rotting food like smell. I’m calling the city health department tomorrow. I hope I’ve figured this out but I also hope this hasn’t affected my health. I’ve been nauseous for months now.

My house is 4 years old. Same chemical smell. Put in to whole house dehumidifiers with outside air dampers. Works pretty good until dehumidifiers shut off. Then smell comes back. I think it is the cinderblock or the concrete. Cold walls inside on hot cinder block . Makes a bad smell. If you close all your windows and doors and tyrn on ur exhaust fans you can smell the smell being sucked in just put your nose by the electrical outlets on an outside wall.
