Mice got into my 2016 Edge. I should have trapped them as soon as I noticed droppings and chewings. But, I didn't.
I thought they would jump out the first chance they got. No! They built a nest, had babies and, then, jumped out. The babies died and the stink started. If this happens to you, you will soon hate life.
First, you have to find them Follow your nose. I eventually had the glove box out, the outside cowl cover removed and the cabin air filter and housing opened up. No bodies. Lots of stink. Hummm...
Remove the passenger seat, carpet, electric inverter (smell getting stronger), duct work, YIPES!! Go outside and catch breath. Found stink source.
Vacuumed up all bedding and bodies. Stink still present. Now what? I considered calling my insurance company and "totaling" the Edge. It was that bad.
After I finished rolling around in the front yard while tearing out my hair, I washed and bleached everything I could access. However, as I cleaned I could see my cleaning solution seeping around and under the sheet metal welds and attachments. I knew I would never get all the "mouse-ness" out.
Coffee, "Nature's Miracle", and Ozone to the rescue. Nature's Miracle is an enzyme based solution that neutralizes the organic compounds I could not get to. After it dried -- and, it has to dry thoroughly before all the stink is consumed -- Celine, the wife, convinced me to put a sock filled with fresh coffee grounds and beans under the seat. I then turned on my Ozone generator for a couple 30 minute doses.
Success!! Mouse stink gone! However, now I seem to be drinking more coffee than normal. Oh well. FYI.
