I made the mistake of baiting mice. They have since died and there is
a real bad odor. They seem to be in the ceiling area of my basement
but am not 100% sure. I don't want to do a tear out. I removed one 4x8
sheet of drywall where I thought they might be - but no. Will the odor
leave when they fully decompose? Any time frame on this? It's not an
unbearable odor - just unpleasant.
Oh, okay. One mouse (depending on the weather), three days to a week.
But, you've put out bait. That means there could be a steady stream of
rodents eating the bait and dying in your inaccessible places.

Think "mass of dead body" there is only so much "food" there.
Depending on local weather conditions (your level of sensitively to
smells) I'd guess a week (or two at the most.)
Mice are about 30g .... about an ounce, not much food there.
Rats tend to take 10- 14 days...hotter the temperature the fewer the
days the more extreme the odor...the cooler the temp not as strong but
can last longer. A single mouse should be a week or less. Cinnamon
candles mask it as well as anything.
I reside in a rural area with some feilds around. I baited the
perimeter (sp) of the home outside. It's a fairly old home and I have
sealed all areas (I think). The basement sump has a clay pipe for
overflow if the power fails or the sump fails. Tracing the pipe by
guesstimate it's opening some 30 feet from the house was unscreened. I

If a mouse can get his head through a hole, he can get the rest of his body,
too. That's about the size of a dime. Unless a house is built today, and
special attention and a lot of cash is spent on that aspect, it is
impossible to keep mice out. Or they just chew a hole through somewhere.
They sound like a much larger animal when chewing through wood in the dark.
I'm tellin ya. Look at the Tin Cats. You won't keep them down in the
fields, but you can get the ones that make it to the house. And if you're
the humane type, just take them all for a five mile ride. I'd dye a few,
though, just to find out if they make it back to their original home.

I sure wouldn't rip down a whole sheet of drywall because of a mouse.
Yes, the smell will go away. In fact I just found a mouse trap behind
my water heater with nothing but a skeleton and some fur. Probably
has been there for at least a year. I did notice a foul odor once
during the hot summer but thought it was sewer gas from the septic and
I knew my wax ring on the toilet was bad. I replaced the ring and
never smelled it after that. Maybe it was the mouse because the water
heater is in a closet next to the bathroom.
In your case, if that ceiling is all drywall, replace that sheet and
before you finish, spray a whole can of air freshner up there. Next
time, drill a 1/2" hole and use that same air freshner. Better yet,
use traps, or a cat and avoid the poison indoors.
Now here's something to think about.
On a scale from 1 to 10, (10 is REAL DEAD), how dead is this mouse?
What was his or her name.
Was it a male or female?
How old was it?
Is it's family grieving?
Was a proper funeral held?
Did it's soul go to heaven or hell?
Was it a smoker?
Did it shop at Home Depot?
Did it have an ebay account?
Where did it work?
How much money did it have in it's bank account?
Who is the next of kin?
Who inherited it's estate?
By the time you answer all these questions, the smell should be gone.
3 days for a dead mouse odor to disappear? I wish. My mice take about 2
weeks to de-odorfy. These are standard mice not rats. Maybe a air ionizer
cleaner will destroy some of the odor during those 2 weeks.
I get at least 1 dead mouse/odor a year in the house. Usually just before
the holidays. On the plus side, no one wants to come over for holiday meals
and if they do, they dont stay long.
Get a cat? I have one and he's dragged in more mice than he's dragged out
I bait but have never smelled a dead mouse. I've found some old
dessicated mice in traps but they did not smell. I would imagine that
if blow flies got to the dead mouse before it mummified, then there
would be an odor as the maggots do their work. Eventually odor will
clear as cadaverine and the odorants committed from a corpse are
volatile organic compounds.
