I think a rodent has died in my heating vents! The smell is horrible, and it is starting to get much worse. I first noticed it toward the kitchen, and then it started getting much worse, and now the smell is also spreading. It is awful. I am pretty sure it is in the heating vents. I've pretty much narrowed it down. I have tried to use the shop vac, with a long tube on it, and I was praying that by chance I would suck it up but no luck! I do not have the resources to go under the house, rip out the insulation, take all the vents off, and clean it out.
What can I do to get rid of the smell? The worst part of this is my poor daughter's rooms are right in the path of the stink. I use candles, sprays, and Plug Ins, but it is just not cutting it. It has been about 2 weeks, so I thought it would be getting better by now, not worse. I am guessing it is much bigger than a mouse, but I don't know. Please help.

I am a retired cleaning lady and have run across this more than once. I have seen rats die in walls, ducts, and in my own home, the attic. The smell is really awful, but it is temporary. It takes about two weeks to go away on its own.
In my own case I had a gap next to a vent fixed on my roof and apparently trapped some rats in my attic. I was able to tape off my range fan with plastic and duct tape and the smell went away. When I took the plastic down (two weeks later) it was gone. I assume there is a dried out rat corpse in my attic somewhere. One of my customers had a rat die in her wall with no way to get to it. It smelled wretched, but two weeks later there was no smell. The are businesses that will come in and clean your heating duct work (vacuum it all out).
I am not sure how much that would cost. I would give it a bit more time, and then call the duct cleaners. You could try plastic over the heating vents for a few more days. Good luck.
This happened to me also, but my son took a "Wire Coat Hanger", bent a small hook on it, took a flashlight to see which vent was closes to the rodent. He then took the wire coat hanger and fed it into the vent until it reached the rodent. He then inserted the hook around or into its body and drug it to the vent he was working from. I hope this works for you,as it did for us. I didn't spend a cent on getting it out.
PS: We had to unscrew the screws that held the vent down.
I also had a dead mouse in the walls some where in between a bedroom and bathroom. Bought all this fresh airbags off Amazon. Waste of money. Have been dealing with this going on 18 days. So i read a article about peppermint oil. I am here to tell you this is some awsome stuff. Put on cotton balls droped in closets,vents,windows and even put some in the air humitifier.
I had been told to put coffee grounds in the vents, but need to add to my answer that I used coffee beans so there was not a chance of dust like particles coming back up from the vent. It works!
How do I get rid of mice urine odor in the ventilation?
Try placing some charcoal briquettes in the vent. Use the kind for the bbq(kingsford). The charcoal will absorb the odor.
I'd try very hard to get to the core of the problem first, otherwise you'll be spraying forever. It could be that just one got in there as a baby and grew up? How'd it get into the ventilation system anyway?
I am moving in to a new house and it has a major animal urine odor. It has new floor and new carpet. The smell is most likely coming from walls or vents. Is their a way I can get rid of it if I can't find it? Or get to it?
Get help NOW before any home warranty or other assurance of structural soundness guarantee expires. Find a flooring specialist or home inspector whom you trust.
Your problem may be carpet installed over the subfloor that had been urine saturated. Unless the plywood is replaced and/or cleaned and sealed, the urine odor continues to rise into the carpet especially when the humidity is high.
The other problem can be carpet installed over concrete that has not been properly sealed.
I bought a foreclosed house (cheap) that had been occupied by five brothers, their guy friends, their girlfriends, some babies, six dogs and MANY cats. (The neighbors were terrorized) The carpet had not been replaced but when my general contractor removed it he and his helper ended up puking on the lawn. It was that bad. The subfloor had HUGE urine spots. I found a flooring contractor who scrubbed it with bleach and vinegar, allowed it to dry, then applied a heavy duty sealer. I had hardwood installed. No problem with that section of the house.
Unfortunately, I had had the carpet replaced in my office IMMEDIATELY after closing. The office is over concrete. The carpet installer pulled the old carpet, did not clean or seal then glued down the new carpet. He assured me it wasn't necessary to do any prep work. The first time I complained they told me the glue would cure. Then they told me to vacuum more often. I am sitting here sniffing cat pee four years later--I finally figured out that this is the room where they penned the cats. I know I need to go back to square one but with file cabinets and a computer armoire to move, I shudder to think what a mess it would be.
I recently had an animal nesting on top of my furnace and now everytime I turn on the heat the house smells of urine! Aside from getting rid of the furnace, what can I do?

Thoroughly clean top and any accessible parts of the furnace, and replace the filter
