The Different Types of Mosquito Foggers and Their Uses

Mosquito foggers are one of the best and most efficient ways to combat different insects, especially mosquitoes. These tools can help you enjoy a nice, mosquito-free time outdoors.

But even mosquito foggers come in a few different types. These different types let you choose the method of dispersing the insecticide fog that is best for you.

Aerosol Mosquito Foggersaerosol fogger

The foggers that are the easiest to use and most convenient to purchase are aerosol mosquito foggers. You won’t need any additional equipment to use these devices, but they tend to be more expensive than thermal foggers.

Aerosol foggers usually come in small aerosol cans (like those used for hairspray, deodorant, or sunscreen). The insecticide comes out of these cans in a fog/mist. These kinds of products are best used for precise targets as they produce relatively large droplets that tend to settle quickly.

Propane Thermal Foggers

This kind of fogger uses propane to produce the necessary power to evaporate the liquid. When ignited, the machine will turn the insecticide into a dense and powerful fog. The droplets produced by thermal foggers are much smaller than those produced by aerosol cans, so they remain airborne for longer periods.

Therefore, propane thermal foggers are suitable for larger, less precise areas. Because the fogger uses propane to produce the fog, you’ll be able to walk around freely and treat any area. You can even take the fogger to a campsite, picnic site, or any other area that you want to have mosquito- and insect-free without needing to worry about electrical outlets.

Electric Thermal Foggers

Similar to the propane version, the electric thermal fogger produces a big, dense cloud of insecticide-laced fog. You can use this in the same areas as a propane fogger to get rid of mosquitoes and other insects.

Instead of propane, this fogger uses electricity to generate the heat required to turn the insecticide into a fog. So, you’ll need to plug this fogger into a power outlet to be able to use it. For some people, this is a big downside because you’ll have to drag that power cord along with you while working. On the upside, though, you won’t need to buy propane tanks, which can run out. As long as you have electricity, you’ll be able to fog your surroundings and live a mosquito-free life.

ULV Foggers


ULV foggerLast but definitely not least is the ultra-low volume or ULV fogger. What makes these different from thermal foggers is that ULV foggers use less insecticide (an ultra-low volume of it). They also produce a spray that is less dense and composed of larger droplets than the fog produced by thermal foggers. The mist from these machines does not penetrate dense foliage as well as that from thermal fogging machines. However, they are quieter and the fog they produce is less visible than the fog from a thermal machine. This may be desirable in neighborhoods, where the appearance of “smoke” may alarm neighbors. ULV foggers are usually powered by electricity or batteries. 


This was just a quick overview of the different types of foggers on the market and how they work. Now that you have a better idea of what each kind can do, it should be more clear which kind will work for you.
