Eliminating cat urine smell from under the house

We have had a problem with stray cats living in the crawlspace underneath our house. I recently bought/made screens for all the vents and access holes, so the cats being under there isn't a problem anymore.

However, the smell of them is still there. Very, very smelly urine/spray/whatever smell. I am going to crawl under there tomorrow and apply some sort of treatment, but my question is: what is best? I was thinking of using baking soda, but I don't know if there is something else that might be more effective.

Anyone have any tips?

Thanks,

Ryan

A cat crawled under our house some weeks go and took a piss. Smelled up the entire house. Fortunately it pissed on the plastic vapor barrier. I found it, tore out that small area and threw it away. Problem instantly solved.

I'd see if it did the same for you. If it peed on the dirt, I'd dig out as much as it took to get rid of the smell.

Best way to get rid of cat urine odor is to get rid of the cats!!

imho:

Baking soda, tries to absorb it, but it's still there. Soaps try washing it away, in this situation, away where? Deep into the soil.

You need to break it down, decompose it. My story, I had adopted a cat from a shelter, he didn't like my other cat, so he refused to use the litter box. He used a corner in my house. Cat was returned, with advice to adopt him out as a single cat/house type and then I started cleaning. All 'pet soil' cleaning products only tried to cover the smell. Then I read you need to break down the urine itself eliminate the smell. I went to petsmart and picked up an enzime solution, "simple solution" a gallon of it, and after following the direction, the smell was gone in a week.

You only need to introduce it to the area, if it's a moise soil under your porch, the enzines producing bacteria should reproduce quickly and work on elimnating the smell. It's possible bacteria is working now, but with the product you can speed up the process.

Bleach will kill the smell. Then splash polyurethane on the wood to seal whatever is stench is left. Worked for me.

Funny you should mention it. I just, as in a few days ago, finished building the backend and ecommerce for this web site:

It was a hellish eleven days to meet their media drop date.

I've never actually used this stuff although I certainly got a chance to read about it and ask folks inside the company about it. They say the claims are for real. The site designer has a dog and told me that Zero Odor works great... much better than Nature's Miracle, which I've used myself with mixed results at best.
