I have a rental house about 960 SQFT and about a year aga we had to evict tenants and found the place full of garbage ETC. and roach infested. We had it professionally treated 3 times before we got rid of the roaches. We also cleaned agressively everywhere we could get including removing cabinets. Had all the duct work & furnace professionally cleaned & fumigated, all carpet replaced, all walls scrubbed down & painted. We still can not get rid of that terrible smell, it must be in walls & attic (floor is a concrete slab) can you make any suggestions? Thanks.
Roaches can cause lingering odors long after they have been removed and controlled in homes, restaurants and other structures. Their feces are easily set airborne and their body parts disintegrate into dust which many people find to be irritating when breathed. Since you’ve done a lot of cleaning in this house already, it’s apparent the lingering odor is living in the floor, the walls or the attic space. I’m inclined to initially believe the major part of the problem will be where the roaches were most concentrated when they were active. However, without seeing the initial infestation or the current condition of the house, it’s not possible for me to offer direct advice from first hand knowlege. But here is a “process” which should, through the step by step elimination resulting after each step, and in the end help you solve the problem.
The key to success will be to apply NNZ over every part of the home you can access. Lightly wiping down walls will help as will spraying the floors, baseboards, etc. NNz will essentially dismantle the old scents at the molecular level which will destroy the odor for good. Its completely biogradeable, works in a few hours and can be used safely in any part of the home.
Where to treat will involve the process of elimination. For starters, I suggest wiping down an NNZ diluted formulation over the areas where you know or suspect the roaches were congregating or mostly focused. This would no doubt be the prime location of the odor. Many odors are actually “alive” and the act of painting or cleaning the area won’t eliminate the molecules as they will get locked into the substrate. True it can help to reduce the smell and or keep it from getting worse. But once it becomes living and then after it locks onto something like wood or concrete, a true odor neutralizer is needed to completely render it gone and deceased.
Mix 8 oz of NNz per gallon of water and plan on getting 500-1000 sq/ft of coverage per gallon of mixed solution. This 1/2 gallon jug can handle 4000-8000 sq/ft total.
Apply the mixture with a sponge, mop or any standard PUMP SPRAYER.
For attic spaces, consider using a good FOGGING MACHINE. These will disperse the product all over in very little time and thoroughly cover everything without puddling or causing leaks below.
For wall voids, use our FOAMING TOOL. Simply add the NNz mixture to the tank along with some FOAMING AGENT and the one gallon will create over 8 gallons of “foam”. This thick shaving cream medium serves as a good carrier of the NNz throughout the void ensuring proper coverage.
Add 1 oz of FOAMING AGENT to the tank per gallon of mixed NNz.
The initial application will yield fast results and where applied, the odor will be rendered useless and effectively it will be “gone”. But if you still notice it in some other part of the home, it will mean there is more area to be treated.
Obviously this could be tough if the floor is covered with tile or hardwood and the problem is essentially “buried”. But carpeting and other furniture can be lightly misted with the NNZ formulation and tile or hardwoods can be wiped down with the same formulation.
Lastly, wall voids and/or attic spaces can be either foamed or misted as explained above. Though many people believe these areas are where all roaches want to live, in fact, it’s far away from where they much rather be residing. Remember, roaches eat what people eat so to be happy, they want to be as close to us as possible. Attics and wall spaces wouldn’t provide such close proximity and is probably why it’s rare such places ever need to be treated. But in really badly infested homes, these spots can become filled with roaches and as a result, need a good injection of NNz.
If done right, you should be able to identify which of your treatments works within a day or two of when you treat. And if you are able to directly treat the odor living molecules with the NNz the first time you try, you’ll no doubt eliminate the source of the problem quickly.
