The Ultimate Mold Foggers Guide

concrobium fogger

If 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 won’t even know it’s 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 can’t 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 include:

  • 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 conventional 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 run and angle the fogger head for optimal dispersal (i.e. not pointed straight at a wall)
  5. Turn the fogger on for the desired time – but not so much that the solution runs on 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’ve chosen a good quality mold control product – then not only will it kill the mold that exists now, it will prevent it from returning.

A mold bomb fogger is even simpler – keep reading to learn more.

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

Concrobium Fogger

Key Specifications

  • Made in the USA
  • Light and even dispersal of formula
  • 400 sq ft of coverage

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

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 are certainly not recommended to actively breath it in when it is in the air.

Concrobium Mold Control Formula

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

Createch Commander Tri Jet ULV Non Thermal Mold Fogger

Key Specifications

  • 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

Our second choice in foggers, 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.

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 formula 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 specialized product.

BioCide Mold Bomb Fogger

biocide mold bomb

Key Specifications

  • Single-use mold fogger bomb
  • Kills 995 of mold and bacteria
  • Removes musty smells and kills mold

The 3rd mold fogger we are going to recommend is a little different, it is called the BioCide Mold Bomb Fogger.

The Mold Bomb is a little different in the way that the product itself is single-use and contains the delivery method (fogging) and the mold killing agent.

It works in a way that is very similar to the fogger mentioned above:

  1. Place the mold bomb in the center of the affected area or near the mold infestation
  2. Remove the cap and push the trigger down until it locks into place
  3. Leave the area for 2 hours

That’s it!

BioCide advertise that the mold bomb itself kills 99.9% of all mold, mildew and bacteria. It even kills the dreaded black mold.

Customers report that the mold bomb fogger works wonders – it kills all traces of mold and even gets rid of the distinctive smell that mold can leave behind.

  1. We plan to use the Biocide mold bombs in our master bathroom and adjacent closet, which is full of clothes. Should it be okay to leave all of the clothes hanging to be treated and also leave everything in our bathroom vanity drawers?

    • One of the great things about the Biocide Mold Bombs us that you can use it to treat the contents of the room. It SHOULD be safe to use without moving anything out. But if there is anything that is especially valuable or special to you then I wouldn’t risk it.

  2. After using the fogger machine, when is best time to do air quality testing so you get pass result? For instance, if you do a test an hour after fogging machine, will it still have some mold or does it kill on the spot?

  3. Is it safe for pets and children to be brought back into my home 2 hours after I use the BioCide mold bomb Fogger aerosol can?

  4. I’m trying to figure out what method to use in a garage attic…… 26×36 floor size with about a 4 ft. center. Would bombs do the trick? How many would I need. I’m willing to rent a Concrobium fogger if need be, but I want to solve this problem for good! thanks!

  5. We have an RV that was kept in a building for 15 years. We had a dehumidifier going. Anyway our friend moved in there as we had the water hooked up etc. and after two months mold was growing almost every where. So because its an RV that has paneling, does that have to be removed to get behind it. Also the furniture and carpet smells like mold and the shades have mold on it also. Its an older model RV so not worth spending a lot of money to save it IF IT CAN BE SAVED. I called a couple mold experts and they don’t work on RV’S. Its 38 ft long about 340 sq ft. What advice do you have . Thanks

  6. 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?

    • I have combated mold problems in many houses over the years. The last project was so bad that all the the insulation in the floor above the crawl space was soaking wet and dripping. Mold everywhere! Now it is mold free. Here is how I did it. First, I fixed the water leaks. The, I ripped out all the insulation that was in the crawl space, especially in the floor. So now the ground floor had no insulation. Then I laid down a construction 6 mil plastic over the entire dirt floor of the crawl space. That kept moisture from up through the dirt into the crawl space. Then I had a company foam the entire crawl space walls, including the window vents that had been there for years. Next, I bombed it with the BIOCIDE MOLD BOMB…they work great, are easy to use and do not leave a residue! Then put in your dehumidifier. Within a week your mold will be dead. It will still be there but dead. You can either remove/scrape/vacuum it off of not disturb it. I do the latter….leave it there and don’t remove it as I don’t want even dead mold airborne. This works perfect!!

  7. 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.

  8. 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?


  9. 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?

  10. 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?

  11. 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?
