Dead Rat Odor Removal?

We finally purchased our dream home, a 2005 38ft Fleetwood Pride 5th wheel. We have been working on lots of issues making repairs and such.
We have a bad odor coming from "all over" the unit. We discovered early on that at least one large rat had eaten lots of wiring in the main wiring cabinet under the floor. the thing was also in the heater ducts and we found where he ate some of the plastic from the inside of a couple of the plastic air duct cover vents.

It looks like he/they were restricted to just the area where the furnace, water heater and electrical connections were.

We surmise it met its end somewhere but have not found his remains. However, the smell persists at times. The basement is the worst area and smells of something dead and a strong urine odor.

I am not going to mention the dealer where we bought the unit but they used lots of dryer sheets, everywhere (in every drawer, cabinet,and closed space).

I am most concerned about the furnace floor duct work as it seems to be the only place I can not get in to.

Has anyone experienced this before and what solutions did you find that worked the best?
We are familiar with the Odo Ban, coffee, bleach, pine sol, baking soda like bad smells in a freezer full of meat that went bad.

  • I had a tiny mouse die in my garage and it took several weeks to dissipate the smell but it finally did.
    If you want to expedite the process then you can rent an Ozinator from someplace like HomeDepot or you can have someone come out with one. I had a service use one on a used TT I bought to remove cigarette odors. The operator told me it was even used to remove dead body smells from buildings.
  • We believe all of the buggers are gone to rat heaven, thankfully. Most of the order is isolated around the compartment that holds the furnace, water heater and mostly in the electrical cabinet which is under the toilet room.
    The worst of the smell is in one of the basement sections which is isolated from the larger basement but is connected to the electrical area under the toilet. That whole compartment is contaminated with bad odor.
    I saw a spot where it looked like something may have decomposed but it is all gone now, I suspect (hoping anyway) that the dealer or prior owner found the remains and already removed them.

    The urine smell is only in the basements, no where inside the unit so I think I can remove cats from the equation.

    When the heat is blowing, we get an initial blast of odor but then it goes away until it sits without use again.
    There were many holes eaten through several of the heating ducts but all have been repaired, not replaced (ughhh). We found no holes along the pathway of the hoses but only at the ends of the pathway.

    So far I like the ozone idea as I have heard of that one before. Thanks for the great input!

    I sure would like to know who owned this unit before but not getting any help from the dealer. I'd like to know what else we might expect.

  • On another subject. If you store your RV use PURE PEPPERMINT OIL on cotton balls around your rv, in living area and below to keep mice away. Don't know if it works with their bigger friend the rat. It kept my RV clean.

    You may have to take sectins of the underbelly membrane down to find the entry source.

    About all you can do is just start removing everything you can that is soiled..

    I had field mice take up living in the air conditioner ducts in my trailer which is parked at the edge of our little woods. If you found activity around the furnace area then most likely they have free run of the floor heater ducts throughout the whole trailer.

    Not an easy task to find the source and clean it up... Like stated above at some point you may have to seek professional help to get rid of it...

  • Odor is caused by decomposition and water leaving the body. With one rat the odor would be gone in two or three days, if you do nothing, so either you have lots more rats or something else causing the odor.

    Urine odor? Cats maybe.
  • You got to remove the source. Call around auto body shopa or the companies that do fire/flood restoration for buildings and find an Ozone Machine.
