Review of the Cutter Propane Insect Fogger

A thermal fogger, when used in combination with a powerful insecticide, is one of the best ways to kill mosquitoes outdoors.

This Cutter propane insect fogger uses thermal fogging techniques and is for outdoor use only.

This tool will vaporize an insecticide into tiny particles that can penetrate even the smallest places outdoors, so it is sure to get rid of any pests that might be hiding in your yard.

This insect fogger works quickly and can provide hours of mosquito-free time. It works with propane gas, so this is a portable unit with no power cords needed. The Cutter thermal mosquito fogger is made in the USA.

Size and Weight

The size of this Cutter propane insect fogger is 17.5x6x9.5 in. (44x15x24 cm) and it weighs approximately 3.5 lbs. (1.6 kg).


Here’s a quick breakdown of all the Cutter mosquito fogger parts:

  • The body of the fogger is made of light but durable plastic.
  • The solution tank is integrated into the body of the fogger and can’t be detached. It has a capacity of 32 oz. (0.95 L) and can be filled using the sealed opening found on one side of the fogger.
  • On the top of the unit is a large handle to make carrying the fogger around easier. It doesn’t have a carrying strap, so you’ll need to hold it in your hand when fogging.
  • Under the handle is a large fogging trigger. When pressed, this pumps the insecticide into the coil to vaporize the liquid and output it as a fog.
  • On the front of the fogger is a stainless-steel burner. This consists of a propane-heated coil (which vaporizes the fogging solution), the basket around the coil (which protects you from accidentally touching the hot coil), and a nozzle at the end (which releases the insecticide-laced fog).
  • To light the fogger, there is an auto-ignite button on the side of the fogger, which sends a spark to the coil when pressed. This is why you don’t have to use a lighter or a match to light the coil manually like with other thermal foggers. If the auto-ignite button doesn’t work for some reason, you can still light it manually.
  • You must insert a propane cylinder in the back of the unit for the fogger to work. The Cutter propane fogger doesn’t include a propane cylinder, so you’ll need to buy it separately. This fogger uses both tall 14.1 oz. (0.41 L) and short 16.4 oz. (0.48 L) propane cylinders.
  • On the side of the fogger, you will also find a fuel control valve, which allows you to increase or decrease the fogger’s fuel supply.


The Cutter propane fogger works at very high temperatures, so there are some safety concerns when using this fogger.

Don’t use the fogger indoors or around flammable objects. It might occasionally spit small fireballs out of the nozzle that could pose a fire risk if used indoors. Also, the heat assembly will get very hot when fogging, so don’t touch it or you could get burnt.


Like other thermal foggers, the Cutter fogger is pretty easy to use. There are few things to note, though.

  1. Fill the container with insecticide solution, but do not overfill it. You should also make sure that there is enough liquid in the tank for the pump to reach it.
  2. After filling the container, you can attach a propane cylinder to the back of the fogger. Make sure there is no dust on the end of the cylinder when you insert it into the fogger. Open the fuel valve a bit until you hear the gas flow and press the auto-ignite button. This should light the fogger’s burner.
  3. Allow the unit to heat up for about a minute before starting to fog. To fog, press the fogging trigger. This will pump the insecticide from the container to the coil, which will heat it and release it through the nozzle as a thick, dense cloud of white fog. If the fog comes out brown or yellow or if the insecticide is dripping through the nozzle, stop fogging and check the instructions that came with the product.
  4. To turn the fogger off, simply close the fuel valve. Then wait for a few minutes for the fogger to stop creating fog.

After a successful fogging treatment, you can expect to enjoy hours of mosquito-free time. For longer effects, you could also fog every couple of days for a few weeks, depending on the insecticide used.

For more information, check the label on your insecticide solution.

Propane fogger not only has the ablitily to kill mosquitoes for about 5 hours, it can kill all your fireflies butterflies moths and other pollinators in addition to all the beneficial insects in your yard and possibly the creatures that prey on the insects. Such as frogs and hummingbirds. My neighbor fogged my yard while I was gone, thinking he was doing me a favor. Where I had thousands of fireflies every night before, there is virtually none now. He fogged my fish pond where I had hundreds of frogs for years, now you don’t hear a croak. Think very seriously before using toxic chemicals on your yard around your pets pollinators and other living creatures.. I suspect the two dead hummingbirds in my yard fell prey to this chemical fogger. Hummingbirds are voracious Eaters of gnats, mosquitoes and other small flying pests.



    I am sorry that happened to you, however, the killing ability of foggers comes from the insecticide that is used in the fogger, not the fogger itself, so here the insecticide is to blame for the devastation in your yard.
    Mosquito foggers are highly efficient devices at fighting mosquitoes, but you also need to pay close attention as to what insecticide you are using and what insects and other creatures it is meant for. In this case your neighbor probably didn’t think to check if the insecticide he was using will harm birds, fireflies and others. So I would suggest to tell your neighbor to closely read the label of the insecticide, and follow the instructions that are written there. This will help your neighbor and you to avoid the heartache of killing beneficial insects and birds, while still reaping the benefits of mosquito fogger.
    P.S. Yes, hummingbirds do eat some mosquitoes, however their diet is not limited to mosquitoes and they actually prefer to eat spiders, since spiders compile up to 80% of their diet.

    Best of luck to you,

I have a new cutter propane fogger…hand held..Question this there any clean-up to the cutter to be done after each fogging? Does the bug spray need to be removed and cleaned out? And.. what about storage,, I read the clips on youtube but did not get a good answer for the small fogger I have..


    Great question, Larry!
    No, you don’t have to remove the insecticide, you can even store the fogger for longer periods of time with the insecticide still inside, just make sure that you do change up the insecticide solution before using the fogger again after longer storage period.
    You should store the fogger upright in a cool and well ventilated area that is out of the reach of children. And don’t forget to turn off the propane valve after you are done fogging.

It seems to work fine by pulling the trigger but I get short, light spurts of fog. When I turn the unit off, I get very large, prolonged bursts of very dense fog. Nothing like what I see when the unit is turned on. Why is this and how long do you think it will continue to vaporize the insecticide when propane is turned off?


    I would let the fogger sit for about 10 minutes after you are done fogging, so all of the insecticide has a chance to vaporize.
    As for the prolonged bursts of dense fog after you turn off the unit, it could be related to the fact that the fogger is still hot for a few minutes after you turn it of and, since you are not pulling the trigger, the fog accumulates and comes out thicker and denser. But I can’t be completely sure, so I would suggest you contact The Fountainhead Group, who manufactures the Cutter foggers, and ask them about this.

We love our fogger but it keeps getting clogged and at one point it was like a flame thrower very scary
Any suggestions?


    I would suggest you to contact the manufacturer immediately, because it sounds like your fogger might have become dangerous to use.
    Other than that, often the fogger gets easily clogged if you don’t let it pre-heat for about 2 minutes before you use it. If this is the case, then you should remove any obstructions from the nozzle before each use and it might work better. But I would still suggest you to get in touch with the manufacturer and not continue to use the fogger, especially if it is becoming flame-thrower like.

Mark Poisson

Am I under fogging? I’ve fogged and still have mosquitoes eating us. How long should I fog the same area for this product to be effective?


    It’s hard to say, Mark, since I don’t know what type of insecticide you are using with your fogger.

Mario Restive

Also a good ideas to detach propane tank when storing the Thermal fogger.


Our unit seems to be clogged. Are their instructions to disassemble and clear the tube.


    Here are some instructions on how to troubleshoot and clean the Cutter fogger. And here is a video of how to troubleshoot a different fogger that also might help you.


My dog and I were on a camping trip and a friend fogged the camping area for Mosquitoes one day and when he was finished he set the Cutter Fogger on a log stump, I noticed the fogger continues to fog and kind of spit out the Cutter insecticide, my dog just happened to walk in front of the unit when it spit out more insecticide on his shoulder area and after it hit him he ran of yelping in pain. After a few days he had blisters, then it scabbed over, once that happened, the scabs came off along with his hair in that area which has never grown back. My question is after 3 months what has caused the hair not to grow back, the insecticide or the burn from the unit?

Be very careful with these foggers!


    It is true, you need to be really careful when using a fogger and fogging insecticide around your pets. That’s why all manufacturers recommend keeping your pet away during the fogging process as well as immediately after and letting your pet reenter the fogged area only once the fog has dissipated and the area is completely dry.
    As for what caused the hair not to grow back, I would say that the burn is most likely to be at fault here since when a burn damages the cells that are responsible for hair growth, they don’t repair themselves and therefore hair don’t grow in areas that have been burnt.


will the fogger kill spiders


    If you use a fogging liquid that is meant for killing spiders with the Cutter fogger, then yes, it will.


Are there any all natural (non toxic) solutions that can be used in the fogger for killing mosquitoes and other flying bugs?


    I would like to know if you can use a different brand of the insecticide other than the Cutter brand. I purchased the Cutter fog machine but it seems like the Cutter insecticide is strong enough or doesn’t last very long.


    The manual says you should only use Black Flag Formula 2, Cutter, or Repel Fogging Insecticide, as the fogger has been designed to be used with those. Therefore, we suggest picking one of those. If you choose to go with some other option, keep in mind that, according to the manual, it might result in unsafe conditions, as well as void the warranty.

Keith Coleman

Is it best to remove the gas canister between usage of the Cutter.


    Yes, you should remove the cylinders when storing the product. You should also keep in mind that propane cylinders should never be stored indoors as well, and always should be kept in a cool, well-ventilated area.

With all of the covid-19 issues…..could the cutter thermal propane fogger conceivably be used with water-based disenfectants? Product manufacturer says no…..why is this? Just for marketing those mosquito based soluctions? Will this thermal fogger evaporate or cause the solution to become gaseous?



    If the manufacturer says it’s not an option then we are not competent to give any other advice. When it comes to disinfecting, cold foggers would be a better option. You can read this article to get some more info on disinfecting with foggers.

I bought a cutter fogger and it worked amazing the first summer I used it. Now the pump spring and ball fell off into the tank. I took it apart and put it back together but the handle now gets stuck and won’t go back down. Do you have a parts break down for the fogger? Also It seems like the tube is clogged because not much fog comes out.


I ignited the fogger – ignite button seemed to work fine, and let my fogger heat up for a very long time, but it never produced fog – when I hit the trigger it kept shooting out liquid. Any idea on what I am doing wrong?


    The manual suggests it might either be a nozzle that’s too loose (tighten the nozzle), the output of insecticide being excessive (pump at a slower rate), or you might not be operating at the right temperature (wait 10-15 seconds before pumping).
