Nisus Bac-Azap Odor Eliminator, Ready-to-Use Bio-Sanitization Liquid, Neutralizes Organic Waste Odors, Safe for Plumbing, 1 Quart

Works very good for rodent smells in RV. Unfortunately, our rodent damage is so extreme it could not remove all the smells, but it did a very good job of removing most of the smells.

Previous owner let mice take over the basement. We finally blocked them out but the odor remained. Ripped out insulation. After trying numerous products that didn't work, I decided to try this rather pricey stuff. One application and the underlying stench has been gone for 7 months. I recommend this on various sites when people have a stink that won't quit. Great product used as directed.

I have used this many times in the past to eliminate organic odors. Since I have worked in the pest control industry I used it for decaying carcasses within wall voids, eliminating other odors as well and worked fantastic. I no longer work in the industry but bought this product because I have a large inaccessible void that got water due to flooding. After all the water was removed and it was all dried out it started to smell really bad. My guess is that the wood in this void had gotten overly saturated and started growing mold and who knows what else is even under there at this point.. Lucky I still have most of my old equipment so I placed the product in my trusty fogger at the 2 to 1 ratio that is on the label and let it rip. The next day the odor was gone but came back slightly 2 days later. Since I have used this before in the same void after hurricane Sandy I wasn't worried because from what I remember even though the smell came back slightly the product kept on working and the smell began to lessen every day till there was none left after a week. So if you use this product have no fear it will work for you just give the tiny good bacteria the time so it can munch away all the bad stuff that maybe growing and causing odor. I have tried other products in the past and recently because I have heard they worked very well but I should have trusted my gut and just used this right off the bat because this product has worked everytime without fail. I'll never use any other product besides this one ever again. Highly recommend 5+ stars. Just a note I read other reviews on this product and seller and it stated that buyers did not get the correct size I had no issue with that. I ordered the gallon and received exactly what I had ordered. Thanks for making a great product it is the best.

So far this Odor Eliminator seems to be working well to rid a closet of a dead mouse smell.

We have a wood stove in our basement but don,t use it.Former family lived in the basement. Anyway we smelled a foul odor. I walked over to the wood stove and opened the door yep thats where the smell is coming from. The chimney pipe has a tee and a round clean out cover that fell down and a young cat crawed inside and unfortunately died. After I pulled the cat out I could still smell the odor the next day. I already ordered this product . When it arrived I placed several onces diluted slightly in a pump up sprayer. I sprayed in the area and the following day I can,t smell anything. But I repeated the process and now will wait 3-4 days and hit it again.I am impressed how fast it is working .I am a ordinary homeowner that takes care of problems without calling the Pro,s that charge big bucks. I read reveiws from them first and based on that bought this incredible odor killer. The only thing it didn,t do is kill the maggots they turned into flies in my basement. I seen about 20-30 at the windows and grabbed my insect spray to take of them.First I opened the window to see if they would fly away many did some didn,t. I also spray this in my nasty trash can and it smells alot better. It almost smell like soap so not a unpleasant smell at all.

I’ve tried countless odor removal products over the years, but Bac-A-Zap is hands-down the most effective one I’ve used. It doesn’t just mask bad smells, it completely eliminates them at the source. I used it in a crawlspace where we had a dead rodent, and the smell was unbearable. Within a couple of applications, the odor was completely gone.

A rodent of some sort died in the inner wall of the bedroom. The smell grew from a mild animal scent to a horrific smell. After a few weeks of the smell only getting worse, I called my 'bug man' and he suggested the Bac-a-Zap after he treated my bedroom wall with it. I ordered it and used it numerous times. It helped with the rotting aroma but I had to re-use it every two days. It is now 6 weeks later and there is still a lingering odor in the room.

Worked great!!!

Only thing that works when you discover rats in your walls.

Sprayed my crawl space brick wall and ground in one area still smells musty for the very expensive price I am going to use vinegar instead next year as I lived in Canada and it is winter now another 100 dollars down the drain
