I have the smell of rotten onion in my basement, we can't find the source. Do you have any suggestions?
I googled "rotten onion smell in basement" and got some really good articles, including one from here in 06. I hope that helps.
Could this be an animal marking its territory, or nesting? I have cats, so don't have such issues. An animal in your case might even be a snake, since they may deposit odors. It is winter and animals seek the warmth of the indoors. I hope you figure out what it is. It seems like an animal must be the source.
Check to see if you have any dry sink or bath tub drains. If you have a bathroom or wetbar sink that isn't used regularly, a dry trap can let sewer odors back into the home. Do you have a dry sump pump?
That could be a decomposition of a mouse or other animal .had that smell coming in my house when winter came and we put the heat on eeventually it must have dried out smell went away but it was around two weeks

We have had this horrific smell coming from the basement for about 5 days. It's working it way upstairs. We went through a storage area where the smell was coming from, but we didn't find anything dead. That's how bad this smell is. The smell is in the bi-fold door to the storage area, but we can't figure out what's causing it.It's Saturday and I called a company that handles odors in the home, but they were closed. We do not have any gas in our home and my husband checked all the drains. Can you give any suggestions? Please?
I am pretty certain that what you are experiencing is a dead animal. I have had this happen to me before, especially at times when i was putting out traps for rodents.
I once spent 2 days where all I did was look for the decaying corpse of something in our apartment. I did eventually find it, but it was not fun. It involved going in the attic, pulling apart a bunch of boxes, pulling the whole house away, etc
Most likely the thing died inside your walls, which is why you can't find it.
it could also be a sewage problem, but I think you would know what sewage v decomposing body smells like.
if it is a dead thing and you just can't find it, take heart: if it's a mouse, it should not last longer than a week. But if it's a bigger thing, you might be stuck with it for up to a month. The thing will smell until the animal has decomposed to the dry bones.
it's caused by rain and the sewers outside your home-dead leaves and other garbage decompose and the smell has nowhere to go but up and out. try and get the neighbors not to rake leaves into the street
How do I remove pet odor from a concrete basement floor?
By ann hr from Indianapolis, IN
Use the "Pee Recipe" - it's not just for pee.
2 c. peroxide
2 t. baking soda
2 small drops liquid dish detergent
Mix gently and then pour on area. Do not wipe up - let it dry on it's own, undisturbed, for however long it takes. The smells will be gone.
My basement flooded. After the water drained it left a terrible odor. What can be used to remove the odor?

My son is selling his house and the basement has a horrible dog odor from where the dogs were kept. Can anyone suggest a solution I can apply to neutralize the smell? The area has a concrete floor.
