How to eradicate smell of dead critter

organica(7RichmondVA)July 17, 2005

A squirrel crawled under my shed and died. The smell is hard to take and of course it's adjacent to my veg garden, where I spend a lot of time. It's going to be hard to get the corpse out of there - any suggestions on something that will eliminate the odor?

If you can't reach the corpse, there really isn't anything that's going to get rid of the odor except for time. Luckily, squirrels are small, & it really shouldn't take long for the body to dessicate.

We had a racoon die under our porch... urrrgkle.

Took about a week for the smell to go away. This hot weather should speed things up.

Can you see the squirrel? How big is your shed? Maybe you could rig up a hook of some sort, or use a hoe, and pull it out. (Or hire a teen-age boy to do it for you.)

I know what it's like trying to cope with that dead animal odor! We were living in Indonesia when I was expecting my first child. A few days before Christmas, it became obvious that a mouse or something had died in the attic. I begged the company driver to go up there (no access from inside the house) and get it because the odor was unbearable, and I couldn't imagine having Christmas dinner there.
From inside the house we could hear the poor guy gagging, and with each sound from him, his tip increased. By the time he came down with, not a mouse, but an enormous cat(!) in a bag, he had a nice holiday fund!

Can you blow some lime in the hole?

I had the same problem once. This might not help with the outdoor smell but it may be useful for inside the shed. If you fill several plastic cups with vinegar and place them in different locations inside the shed the vinegar will absorb the ordor. Keep the jars away from other pets.We had a critter die in the attic once and the smell inside the house was horrible. It didn't get rid of the odor 100% but it we were able to live with it without gagging everytime we entered the house. I would say it made about an 80% improvement. I also burned alot of incense!

Byron, any particular kind of lime? I have some horticultural lime left over, will that work?

Thanks, folks, for these suggestions and stories. Not long after we moved into our house, an odor started to grow stronger and stronger in the bathroom. Turned out to be a dead mouse in a trap, thoughtfully left behind by the seller. We still haven't completely gotten rid of the smell but spraying bleach on it helped.

There's nothing like that dead animal stink.

I don't know if this will help with dead critter smells, but I once got a good hint from a flight attendant on dealing with (in her words) big smells in small rooms.

She put the coffee filter pack for the coffee machine in the restroom, and it did a good job of absorbing all the offending odors.

I just scored a bunch of coffee grounds. In fact my husband and I were discussing the deodorizing power of same, but I failed to make this connection re the dead animal smell. Thank you!

My husband's a former truck driver and he explained that coffee grounds were useful in eradicating the smell of the previous load. If for instance he had just hauled onions and was on his way to pick up strawberries, he had to get the onion smell out or the strawberry supplier wouldn't cooperate.

I'll try it!

When my father was dying of cancer, he started to get bedsores and the smell was bad. We were nursing him with the help of the local hospice at home. We put 3 charcoal briquets around the room (the ordinary kind that you use to grill with) and the smell just about disappeared!

I tried the coffee grounds yesterday afternoon, and it seems that this morning the stink is gone! I just dumped them along the opening where the unfortunate squirrel crawled in.

I just bought a used freezer and thought it was great. Only after I got it home did I smell a "dead mouse" smell. (No, the smell isn't in my clean garage) I've cleaned it thoroughly and still can't bear the thought of putting my food in it. Also I vacuumed underneath after I cleaned the inside. About 20 minutes ago I tried pouring Clorox bleach down the drain located at the bottom-back, inside the freezer. Don't know yet if that will help. The freezer has been airing with door open in partial sun in the open doorway of my garage for three days. Don't want to spend another $50 to have it returned to the previous owner. I will also try the coffee and charcoal tips but will continue to watch this "dead critter" blog in hopes of getting even more good tips.

uhhh uhhh....the dead mouse smell is more than likely dead meat!! LOL your gonna have to spray that bleach up in the bottom of the under part, been there done that, when moms electricity went out, theyare truck drivers and we had to go check on stuff. forgot about the freezer downstairs. and when they got in... well lots of meat went to waste. and so we cleaned it good, but that smell!! so i had to spray the bleach up under and back and it finally worked. also letting the bleach drain down the hole was a great idea!! use a bathroom toilette brush to knock anything loose. it'll clean it good. then spray it one more time. then go ahead and give it a good spray with the hose. your done. but let it dry good befor ya turn it on. LOL i know. duhhhhhhh!!! LOL **big grinn*** its a mommy habit!! LOL ~Medo

Hello :-)
We have "something" that died under our home and the smell is getting to where we are going to move in with the kids at their home until the "animal" death smell is gone or at least tolerable.

We have had 2 men go under the home and cannot find the "animal". They said there was a lot of "poop" but it was hard and not fresh.

Since they could not find the "animal" there was really nothing they could do!

Any help will be wonderful. We've already called Christmas Dinner off and having at the kids house.

Thank You,
Pamela

Baking soda is an old standby for eliminating odor. Either throw some on the body, or if you can reach it, mix up a storng solution with water and spray it on with a garden sprayer. Do it every day or so until it rots away. Baking soda works wonders with odors.

Not completely related, but close...

You can use baking soda on your carpet as well, but don't do what I did...

I had a sick dog (I had some red onions curing, and the box got moved from it's higher location, and i suspect he ate some). Let's just say, he's a big dog, and it was not pretty, what I woke up to find in the morning. So, now I had a couple spots to clean on my carpet. After I cleaned up and shampooed it with my little green machine, there was still a pretty unpleasant odor. I had a really big box of baking soda, and dumped quite a lot on the moist carpet. Then I brushed it down into the carpet with a scrub brush.

The odor was gone (thank goodness!!) but I'm still working on getting the baking soda out. I have vacuumed. I have "rinsed" by pouring clean water on and sucking it back up with the little green, many times. I've poured water and used a towel to absorb it. It's become an ongoing project. I need to work on it some more this week...

I'm so grateful for all the advice in this thread! We have something dead (probably a mouse) in the basement wall. The whole basement is filled with dead animal odor and unfortunately for us the heating system is sucking that dead animal smell all over the house. YUCK! We can't get to the problem without ripping walls open and we're not quite sure where it's even coming from. After living with the smell for 5 days, I found this thread. This morning I puts cups of vinegar, a bunch of charcoal briquets around and 2 boxes of baking soda. I found a small hole in the wall where some of the smell seemed to be coming from and shoved a few briquets in the wall and left one in the hole. Anyways it's been a few hours and I would say that the smell is about 80-90% better! YAY! Thanks again!

I'm going to try the coffee grounds too... does anyone know if they should be wet or dried out?

First of all, thanks to everyone who posted on this page. My husband and I walked into our house almost two months ago (coming home from work) and it hit us. That is the worst smell imaginable. I tried everything on these pages, and I have to tell you that none of them really worked very well. We had people come in and try to find "the critter." It was in the basement, but not behind a wall (we broke through a wall, not there), but under the cement floor, and it would have been too costly and disruptive to break through the cement floor. So, we waited. Used all kinds of "deodorizers" -- coffee grounds, baking soda, charcoal briquets, vinegar, air fresheners, nothing really helped. I did pour some lime down the hole (there was a small hole behind the wall in the cement) and that may have helped a bit. It does go away eventually, and it is easier once the warm weather comes because heating system seems to blow it all over the house. There is a product called OdorCide and that does help if only temporarily. Keep spraying it every few days until the odor goes away on its own. It was a nightmare. But it did make it easier to read about everyone else's trials and tribulations with this problem. And to anyone who has this problem, let me just say that IT WILL GO AWAY with time.

We buried our sweet cat just shy of 4 weeks ago in our garden, though about 18-19" down we hit a bedrock of sorts, having broken one shovel & one pickaxe. We lined his grave with straw, then carefully placed Colby, then more straw...and mounded dirt on top, finally surrounding his grave with stones. One caveat - he's in our veggie garden; I intend to plant flowers on/around his grave, but am also curious about just how far away is far away enough to consume produce grown near an animal's grave...?

Yesterday I went down to cut some mint (a good 15 feet away from where he was buried), and was hit with that distinct 'dead animal' smell. I didn't investigate; I was in a hurry & didn't confirm that the smell got worse the closer to Col's grave one got...though obviously I'm concerned that that's the case and that it's not another unfortunate animal. We live in Altadena (a suburb of Los Angeles) - it's August & the heat ain't going away any month soon. That being said, I'm hoping that it will make his decomposition happen faster (gruesome, but there you have it - life, and death, do what they do).

So - should I be making baking soda / lime solutions & soak his grave? Should I pour (possibly diluted) vinegar or coffee over the area? Or, heaven forbid, do we need to rebury our poor baby? I'm at a loss. I can put charcoal also around his grave; that might be a first start.

Any insight would be most welcome!

I have a dead squirrel somewhere in the wall and I need to ask about the coffee grounds to help with the odor.

Am I putting the grounds out in a plate or bowl of some sort in the area of the odor?

Thanks!!

My experience with dead animal smell was similar to some of yours we had a squirrel that found his way into our attic for storage of nuts, he was good at hunting around and found his way into a wall where he eventually was trapped - dead squirrel is not a good smell for the house. We found odorknockout a fogger that is used at car dealers to get rid of cigarette smell and gave it a try. It take a couple of hours but destroys all the smell. I recommend it for cigarette smells or dead critter smells. It is manufactured in Tennessee www.odorknockout.com

So, over Christmas I went home to my parents just as they had this awful dead mouse smell. They said they had discovered it the night before, and had vacuumed a dead mouse out of one of their floor vents, but the smell seemed to keep lingering/coming back. We would run the whole house fan and freeze out the house, but every time it kept coming back. Over the week I was there we tried EVERY suggestion on here. They helped some, plus my mom put out eucalyptus oil and candles, which combined with the vinegar basically created a pickled dead mouse smell that was slightly fainter. I went home, and the smell got worse for them. Two weeks ago they finally tore into the wall to try to find it, and nothing, but again the smell eased up. Finally, they were at the point that many other mice had been found dead, the dog refused to go into the house, and my mom said the mouse smell had started to have a chemical edge to it that my mom was concerned about going inside at all, let alone sleeping. Turns out, they had a propane leak. Propane is apparently scented to smell like dead mouse so that people will notice leaks. They had checked for leaks not knowing that propane is dead mouse scented, but had missed the bendy pipe which is where their leak was. I'm posting in response- just in case some future person has this smell that will not go away to be aware that you might check for propane leaks. They had visited home improvement stores several times trying to get help about the smell, and no one there knew, and I'm not sure that most people will think to search for what else smells like a dead mouse. Anyhow, hope this might help the next person.

Maybe you can use a strong soda solution or sal soda or even some lime in the drain. A soda paste will remove lots of odors. I always hate the way my pot holders smell like rancid grease. Soaked them in a strong soda and water solution and bravo, they smell nice again. Just washing doesn't seem to do it. I also have a guaranteed solution if you have skunk odor in the house.

For those having trouble finding the smell:

We had the same problem. We couldn't find it anywhere. Finally DH tore the side of the cabinets off. A small groundhog had died under the cabinets!! EWWWWWW

We are still dealing with the smell a little. I will surely be trying some of the tips here. I had to clean out a small storage space next to the cabinets because the stuff in there picked up the smell. Now I need to get the smell out of there too.

Thanks for the tips

The dead animal is somewhere in a rock retaining wall under my porch. I can see where the flies are congregating, but I can't take the wall apart to get the animal out. How do I use lime to get it into the spaces between the rocks? Is it liquid or granular?

Yuch! Last night there was a dead animal smell in a corner of my bedroom, today the whole bedroom stinks. A critter must have died in the attic. Not small, this is a huge smell. I thought about gas but then the first floor would have the smell also. I'm going to put coffee grounds and vinegar around the room. I have an air filter going. I'm sleeping in the den tonight. Thanks for the suggestions.

Brenda, agricultural lime can be found at any box home improvements store for a reasonable price, just bury the source of smell under a thich coating of this, if you can't remove the source.

(not suggesting brands, just for info)

Just had this problem with a dead animal, mouse, mole or chipmunk in my brand new car! Somehow it got into the car, toyota took the car apart, and i mean they gutted it. They couldnt find a thing! They said it must be in the frame of the car. It smelled so bad, i couldnt drive it anymore. I am sure it it is bad for your health too. 3 weeks later they decided to put the car back together again. I will find out tomorrow if it still smells. If it is i dont want it anymore, it has only 20,000 miles on it and i feel like it is ruined! But yes, it smells bad and i might have to use vinegar and coffee grinds, ;) and did i mention i have two kittys now?!

Thank you for all the great ideas! I live in the country and the mice this year with all the flooding have been horrible. I used mice pellets and, no, mice don't go outside for water! They die in behind the cupboards. I will put baking soda, vinegar, charcoal briquettes and coffee grounds in hopes of getting rid of that smell! I have also tried different types of mouse traps-the ones with glue on them, the old fashioned ones, the upgraded dual ones with glue but the mice just aren't interested. I discovered them eating the dog food and put that up at night but don't have any other food around. Anybody have any good mouse trap brands?

I have a dead rat smell in our house and I have no idea where it is coming from. We have gone under the house, in the attic, and under the house smells terrible. In the house is even worse. This smell doesn't let anyone sleep. We have looked for dead mice or rat but have found no source. Any ideas?

We had this problem last year, and finally the dog found it.
So, borrow a dog if you can and let him sniff it out.
Best thing for the smell was then contractor strength bleach, sprayed on the offended area (after the racoon was removed.) Had to pull apart the house a bit to get the dead racoon out, but was well worth it. Good luck!

I just read through ALL these helpful posts because our house has yet another dead mouse (drafty cabin in the woods with 2 cats that like to play with -- but not actually KILL -- mice). This time I think it went into our ceiling to die, and I know the smell goes away in time, but I wanted to share our successful strategy for past mice, especially because it's halfway between living with the smell and tearing out your wall/floor/ceiling.

Find the place the smell is coming from. I literally go around sniffing power outlets, light switches, and gaps in the floorboards. If you find the animal, as others say, get rid of it and treat any lingering smell, great suggestions here.

If you can isolate the smell to a specific section of wall -- like, once a mouse had died between two joists in our TV room -- seal off the outlets. We have used plastic wrap and tape, but since some of our walls are smooth, I actually slapped a big square of Glad Press-n-Seal over the outlet and light switch and left it there for a few weeks.

Every week or so I peeled back a corner and sniffed, and when the smell was all gone, I took off the plastic.

This time, the smell is in the ceiling and became stronger when I plugged up a hole by the wall with steel wool, so I realized it was leaking down out of big crack between two ceiling panels. I covered that guy up with a long strip of blue painter's tape and so far, so good.

Off I go to place strategic bowls of coffee grounds around the house! Thanks for all the useful info.
