part 2 because this seems to happen at least twice a year here...
My house smells like an 800 pound man's farts after eating chili, cabbage, and Mexican food! I can't find the smell, AGAIN! I threw all of the potatoes out, all of the garbage in the house, cleaned the fridge.... It still smells! My dog likes to take things out of the garbage and hide it for later. I find things all over the house that she has hidden. I have no idea where or what the smell is. It is just horrible. The cable guy came here today and I am surprised he didn't puke. I wish I could bottle the smell and send it out over the internets so you could help me identify the source. It may be time to just burn it down and start over.
Have you had new carpet installed or perhaps new drapes??
When you buy new sheets the package tells you to wash them before use, new bed spreads or new furniture.??
You say twice a year, could the smell be coming from the ground outside?? A small gas leak with the rotten egg smell could be your problem or even a pin hole in the septic system can by climate build up inside when the windows and doors are kept closed for months.
Heating systems and the air vents that get gross when not cleaned every couple of years, mold and mildew in air conditioners can also give off a putrid smell
.MAMA, smell is a survival method for people and animals to tell us what is good and what is bad. The smell of liver being cooked will gag me and I do not know why.
Couple times a year something is going on due to humidity, temperature and most likely is not a dead rodent in the walls. Something is activating the smell or you would have it year round.
Not to scare you ----News last month told of people in an apartment complex kept complaining of bad smells to the owner and the public works. Both did an investigation and could not find the reason for the smell. When TSHTF and half a block was blown sky high due to a pinhole leak in the natural gas pipes.
Please investigate and ask questions of neighbors this is not normal, and have your water tested, as a precaution.
