Propane foggers are one of the most efficient ways to get rid of mosquitoes. This kind of fogger is compact, so you can use it anywhere: in your garden, your backyard, a campsite, a picnic site, and more.

The fact that the thermal foggers use propane to create heat makes them really great at eliminating mosquitoes. But there are a few things that you should know about propane foggers to ensure your safety and the safety of those around you. So, here are our tips for using a propane fogger safely and efficiently.

Safety Tips

Because you’re working with a propane fogger and using a propane tank to power it, you’ll need to know how to properly handle it.

First and foremost, you always need to tightly close all valves on the propane cylinder after use.

It doesn’t matter if the tank is empty or still half full. This simple action will ensure that propane can’t leak from the canister, causing fire or injury.

You’ll also need to store the propane cylinder safely and properly.

You can’t store propane tanks near areas where the temperature is over 104ºF (40ºC). This includes any areas near heat sources such as fireplaces, stoves, and so on. Any heat source or room where it’s very hot will create pressure inside the tank, which could possibly cause the cylinder to accidentally release propane. If this comes in contact with fire, it can even cause an explosion.

It also isn’t a good idea to store propane tanks indoors or in enclosed spaces such as basements, sheds, or even garages.

Don’t smoke or have any open flames or sparks near the propane tank.

This may seem like an obvious tip, but it never hurts to be reminded of this fact. Having any source of fire or sparks near a propane tank could end in fire or an explosion and could cost you your life.

If you want to use your propane fogger outside your garden or yard, learn how to transport it properly.

First, you’ll need to make sure that the cylinder is in a secure, upright position. You also need to be sure that it can’t fall or move around the car. This will ensure that there’s no way the valve can come undone or that anything can happen to the fogger.

You also need to make sure that your vehicle isn’t too hot and is well ventilated. This will keep the pressure from building up in the canister. As soon as you arrive at your destination, immediately remove the cylinder from your car to further ensure your safety.

There will always be the possibility of your propane cylinder somehow getting damaged.

If this happens, you absolutely can’t use it – even if it’s leaking just a tiny bit. To check if your propane cylinder is leaking, you can perform a simple test called the bubble test. All you need to do is to apply a leak detector solution (or thick, soapy water) on the valve and any other places that might be damaged. Then slowly open the valve and check for bubbles.

If bubbles are forming, close the valve and reopen it to double-check. If the bubbles continue to appear, then you have a damaged propane cylinder and you need to safely dispose of it.

Never throw a propane tank in the trash.

It doesn’t matter if the tank is old, empty, broken, etc. When the time comes to dispose of your old or damaged propane tanks, you’ll need to find a place that specializes in this kind of thing. There are specific ways of getting rid of propane cylinders to keep yourself, trash collectors, and the public safe.

Efficiency Tips

Here are a few additional tips that can ensure more efficient fogging in any area.

The best time to fog any area is at dusk, dawn, or in the late afternoon.

These are the times when mosquitoes are the most active. Therefore, this is when you’ll have a better chance of getting rid of most of them.

Make sure that you fog everywhere.

Fog all areas including all bushes, corners, nooks, and crannies. These are places where mosquitoes like to hide the most, so you want to be sure to get each and every one.

Don’t fog when there is precipitation or heavy wind.

Both of these factors will cause the fog to dissipate more quickly. If this happens, it won’t have time to settle on the ground or on the plants and do its job, wasting your time and fogging solution.

When fogging with a propane fogger, make sure you always wear some kind of protective gear.

You should at least wear gloves and a respirator. Even though the fog is not harmful to humans or pets, the person fogging will generally get the most concentrated dose of the fog. This can always cause an allergic reaction because you’re working with insecticide, after all.

I thought it was interesting that you mentioned properly storing it. My brother is looking to buy a biological fogging system but is looking for tips as well. I’ll be sure to talk to him about storing it properly after buying.

Have you ever heard of fogger misuse to the point of fire and flash ?
Situations to avoid. Someone told me that they put petrol in a propane powered fogger. My response was that i thought it was a very bad idea on every level. Please consider and advise.


    Putting petrol in a propane fogger is definitely a bad idea!
