The Ultimate Mold Foggers Guide

concrobium foggerIf you have ever had a mold outbreak in your house then you probably know that the mold you can see is only the beginning of the problem. Believe it or not, only 10% of mold is visible – the other 90% is microscopic. On top of this, there is usually even more mold behind the scenes in the roof space, wall spaces, heating and cooling ducts and many other places that are inaccessible.

This is where a mold fogger such as the Concrobium fogger (in our opinion this is the best mold fogger) can make your life so much easier and have the mold problem under control in record time.

Why You Should Remove Mold

Mold is part of every day life, it is everywhere and most of the time you will not even know it is there. But there are occasions when mold growth takes off and it becomes visible and has the well known moldy smell. This is when moldy environments can become a hazard to humans.

Not everyone is sensitive to mold, but those who are will find that a moldy environment causes a variety of health problems. According to the CDC mold can cause the following symptoms:

  • nasal stuffiness
  • throat irritation
  • coughing or wheezing
  • eye irritation
  • skin irritation

Even more at risk are people with compromised immune systems or chronic lung illnesses. When exposed to mold, these people may get serious infections in their lungs which can be life threatening.

Why You Should Use a Mold Control Fogger to Remove Mold

As we mentioned earlier in the article, you can only see a small percentage of the mold that actually exists in any environment; 90% of mold is microscopic.

So if you have mold showing on your walls, then you can guarantee that there is mold covering other surfaces in the room that you cant see. Just cleaning the mold you can see is not removing the mold completely, only a small part of it.

There are other methods of cleaning mold on drywall, but using a cold fogger fills the room with a fine mist of the mold remediation chemical, this mist then evenly coats everything in the area and kills the mold on all surfaces.

This is why we believe that the only way to treat a mold outbreak is with a cold mold control fogger.

Some of the areas and items that a mold control fogger would be ideal for removing mold from includes:

  • Basements
  • Rooms with a lot of Furniture
  • Bathrooms
  • Rooms with lots of Windows
  • Attics
  • Wooden decks/patios
  • Under the house
  • Crawl spaces
  • Roof spaces
  • Garages (heating your garage can help keep mold away)
  • Sheds
  • Walls

How to Use Foggers

Using a mold fogger is certainly not rocket science, but it does help to get your head around the process before deciding if using a fogger is right for your needs.

  1. Clear the area to be treated of any items that might get damaged by getting damp or wet (some furniture, electronics, paper etc)
  2. Add your mold control liquid of choice to the fogger tank
  3. Adjust the liquid flow rate settings on your chosen fogger to your desired setting
  4. Set the fogger up where it will be ran and angle the fogger head for optimal dispersal (ie. not point straight into a wall)
  5. Turn the fogger on for the desired time – but not so much that the solution runs or surfaces and pools
  6. After you have turned the machine off, let the area sit for half an hour so that all the fog has settled
  7. Open windows, turn on fans and allow the area to dry

That’s it! There is no rinsing required, and if you have chosen a good quality mold control product – then not only will it kill the mold that exists now, it will prevent it from returning.

The Best Mold Fogger

There are a number of different brands you can choose from if you are in the market for a mold fogger, here we will list a few of our favorites and why we chose them.

Concrobium Fogger

Our favorite mold control fogger by far is the Concrobium fogger. It is a sturdy, well built fogger than can fog any area up to 400s sq ft in a single application.

Concrobium 200-620810 Mold Control Fogger
  • Automizes Concrobium mold control into a fine mist
  • Fogging is ideal for treating and pre treating various surfaces
  • Ideal for large spaces and hard to reach areas
  • Use in musty rooms to eliminate odors
  • Use to pre-treat Building materials during construction or Renovation

Clear instructions are included with the unit that cover everything from setting it up, to how much Concrobium Mold Control you will need for your intended room size and how long fogging will take. The fogger produces a very light, even mist of the Concrobium Mold Control formula and fills the room and coats all surfaces perfectly evenly. Many of the competitors in the market use a much heavier fog because more of the chemicals they rely on are required.

Concrobium Mold Control Formula

The Concrobium mold control formula itself is by far the best you can get. It is labelled a “natural spray”, it contains no ammonia, bleach or volatile organic compounds – what this means is that it uses a natural base of chemicals that are not as toxic as many of its competitors. In saying that though you certainly not recommended to actively breath it in when it is in the air.

Concrobium Mold Control Household Cleaners, 1 Gallon
  • Kills, eliminates, and prevents mold
  • No ammonia or vocs
  • Works on drywall, concrete, wood, masonry, siding, shingles, stone, grout, plastic, tile and many more surfaces
  • Can be used on all surfaces interior and exterior.Crushes and suffocates mold as the product dries
  • Eliminate source of moisture. Spray directly on mold and allow to dry.No bleach, ammonia or harmful chemicals

It is safe to use on most surfaces, even carpet and timber without any damage to your valuable furniture or floor coverings.

While some mold control solutions are what they call ‘encapsulates’, this means that the product just traps the mold and stops it from spreading without actually killing it. Concrobium mold control actually goes further and kills the mold – eliminating it for good. It actually leaves an invisible antimicrobial shield which prevents the regrowth of mold and mildew, meaning this is a long term solution and not just a quick fix.

Createch Commander Tri Jet ULV Non Thermal Mold Fogger

Our second choice in foggers is the Createch Commander is an American made cold fogger that serves multiple purposes. It not only does mold control fogging, but can also be used to fog any other sort of chemicals such as insect fumigation and sterilization/sanitation.

Tri Jet ULV Non Thermal Fogger

  • Made in the USA
  • Can be used indoors and outdoors with oil or water based materials
  • suitable for mold and mildew control, sterilization/sanitizer fogging and pest Control Fogging

I mentioned that this mold fogger is made in the USA, and that is probably the reason why it is such good quality. The price is also spot on, with it being a bit cheaper than the Concrobium model.

The Createch Commander mold fogger does not have a recommended anti mold formula, instead you can use almost any cold fogging formular available. This makes it a little less efficient than the Concrobium fogger due to the fact that it is tuned to work for a broad range of products instead of one specialised product.

  1. I have a crawl space with a sump pump. I also have a vapor barrier installed. Discovered a couple of plumbing leaks and with the increased rain and high humidity I have developed a mildew, mold, fungus issue under the house. I am going to treat with the Concrodium Mold control fogger. Should I remove the vapor barrier prior to treatment so the chemical can get into the dirt? Also, will the fogger get the mist to the subfloor wood?

  2. Do I need to wipe off or clean item and wall hangings after fogged? Also, are my drapes and bedding ok to leave out and be fogged as I am sure they have mold spores on them also.

  3. I have a room with a 30′ ceiling…using a Tri Jet ULV fogger….any suggestions on getting fog to that height or do I need to get multiple foggers to create enough fog and put a fan on it?


  4. Thanks for your response! I’m guessing it’s around 1000-1200 sq ft. Any thoughts on can fogger versus fogger machine rent or buy? We definitely are focused on drying the space out, and got the water out right away. From what we can tell, it’s dry. The temp is hot where I live (high was over 90 today), so heating the space at this time could be hard on the AC and not pleasant for us. I see your point though.

    • That does sound like a large space for a can fogger, but this kit MIGHT do it. Otherwise I guess it depends on if you think you will need a fogger again in the future? Will it be a good investment?

  5. I have a music keyboard and a guitar amp in the molded room. There are also papers and different small objects on a table in the room. What do I do with these Items?

  6. I used the fogger from Home Depot. I aimed it at a wall behind and under the kithen sink. Afterwards, I put a fan on so it would dry. Even at the opening of a hole we had in the wood wall, we have a pipe and other things. The wall is white but the stains are still black from the mold. I thought they would lighten up a bit. Is the mold gone?


      • We had a sump pump break and consequently a couple of inches of water in our basement. The basement is unfinished with cement floors, and we have a dehumidifier running, but there’s still a noticeable musty odor. There’s no visible mold or mildew. Would you recommend I use a can fogger (less expensive option) or purchase a fogger and separate chemical (significantly more expensive). Thanks!

        • It depends how big your basement is. But I think what you really want to do is get that area dry as quick as you can. Have you thought about heating the area for a few days to see if it improves the musty odor?
