Does Propane Kill Gophers & Moles?

Yes, propane can be an effective gopher and mole killer when mixed with oxygen and detonated with an ignition source. This method is often referred to as a “propane gopher killer” or “gopher flares” and involves dispensing a gas mixture into the tunnel or holes of burrowing rodents.

How to Use Propane to Kill Gophers and Moles

Prior to attempting the use of propane gas as a method to eliminate gophers and moles, it is crucial to acknowledge that it may not be legal or safe in all locations, and it is essential to verify with local authorities. 

If you decide to kill moles with propane gas, here are the general steps:

Locate Active Tunnels

Walk around your property and look for areas where moles or gophers have been active.

Active tunnels will have fresh soil pushed up from underneath.

Insert the Probe Into the Tunnel

Insert a propane gas injector probe into an active tunnel.

The probe should be placed down into the soil at an angle so that it is pointed toward the center of the mole tunnel.

Inject Propane Gas

Attach the propane gas tank to the injector and slowly release propane gas into the tunnel.

The amount of gas needed will vary depending on the size of the tunnel.

Ignite the Gas

Once the gas has been injected into the tunnel, ignite it with an ignition source such as a barbecue lighter or long match. Stand back from the area to avoid injury.

Wait and Repeat

Wait a few minutes to allow the gas to disperse through the tunnel system.

Check the area for signs of the mole’s and gopher’s demises such as a lack of new activity or dead moles and gophers near the treated tunnels.

Repeat the process in other active tunnels as necessary.

It is recommended that you wear protective clothing and safety equipment such as gloves and safety goggles when using propane gas for mole control.

It is also important to follow all safety instructions and precautions provided by the propane tank manufacturer.

Pros of Propane Gas to Kill a Mole


Propane gas, when introduced into mole tunnels, creates a toxic environment that is lethal to moles.

Propane gas displaces the oxygen inside the tunnels, leading to the suffocation of the moles.

Wide coverage

The wide coverage of propane gas is particularly advantageous when dealing with moles that have complex tunnel systems or when it is not feasible to identify the exact location of the mole tunnels.

Propane gas can penetrate deeply into mole tunnels, reaching areas where other methods that require placing bait or traps at specific locations may not be as effective.

Quick results

Propane gas, often used in combination with a mole-specific trap, can quickly and effectively eliminate moles.

When propane gas is introduced into the mole tunnels and ignited, it creates a powerful shockwave that instantly kills the mole. 

Minimal cleanup

Propane gas is an effective method for killing moles, and one of the advantages is minimal cleanup.

When using propane gas to kill moles, there are no remains or carcasses left behind, unlike other methods that involve handling dead moles.


Depending on the size of your property and the extent of your mole or gophers problem, using propane gas can be a more cost-effective option compared to hiring a professional exterminator.

It is important to bear in mind that using propane gas for mole extermination may have potential risks, including damage to vegetation or the risk of accidental ignition if not handled properly.

Cons of Using Propane Gas to Kill a Mole

Safety concerns

Propane gas, when mixed with oxygen and ignited, can be highly explosive and dangerous if not handled properly.

If the gas is not used in a controlled manner, there is a potential risk of accidental ignition or explosion.

Damage to vegetation

Depending on the location of the mole tunnels and the way in which the propane gas is used, there is a possibility that nearby vegetation could be damaged or destroyed.

Difficulty in application 

Propane gas needs to be injected into the mole or gophers tunnels in a specific way and ignited with an appropriate source.

The successful completion of this task may be hindered by the lack of expertise and equipment among certain individuals.

Ethical concerns

Some individuals may have ethical concerns about using lethal methods to control pests like moles and may prefer non-lethal alternatives.

Environmental Concern

Propane gas, being a fossil fuel, poses concerns as its usage contributes to the emission of greenhouse gases, resulting in climate change.

This may be a concern for individuals who prioritize environmentally-friendly pest control methods.

Frequently Asked Questions

Are there any potential risks associated with using propane to get rid of gophers and moles?

Yes, there are potential risks associated with using propane to get rid of gophers and moles.

These include the risk of an accidental explosion, the release of propane into the atmosphere, and the potential for injury to pets or humans if not handled properly.

It is important to follow all safety precautions when using propane for gopher and mole control and to use it only as directed.

If you are looking for a less risky way then you can use dry ice to kill moles and gophers.

Will Propane Gas Kill a Mole?

Propane gas is a potential option for mole eradication as it creates a toxic environment in the tunnels. 

However, it’s important to handle it carefully to avoid damaging vegetation. 

Alternative options like store-bought gas bombs or baits such as Tomcat Mole Killer and TALPIRID Mole Killer are also effective solutions.

Does Gasoline kill moles?

Although gasoline has been utilized in the past as a means to eradicate moles, it is not a suggested technique due to its inherent risks. 

Gasoline is a volatile liquid that is highly flammable and can easily ignite, resulting in fires or explosions if mishandled. 

Furthermore, employing gasoline to eliminate moles can result in environmental harm by polluting soil and water resources.

Which Gas is Effective to Kill Moles?

Carbon monoxide, Propane gas, and Calcium carbonate have lethal potential against moles, making it crucial to be cautious and strictly adhere to safety measures when employing them.

Mishandling propane gas, for instance, can result in severe explosions and hazards. 

It’s also imperative to verify local regulations before employing any gas injection techniques.

Can propane be used as a long-term solution to keep gophers and moles away?

Propane can be an effective long-term solution to keep gophers and moles away.

However, it is important to note that propane-based solutions are usually used as a one-time treatment rather than as a preventative measure.

Therefore, it may be necessary to repeat the treatment periodically to maintain control over these rodents.

Additionally, using propane alone may not be sufficient to keep all gophers and moles away, and other preventive measures may be required to ensure long-term effectiveness.


In conclusion, propane is an effective way to kill moles. It can be used safely and may potentially aid in preventing future infestations. 

Nevertheless, exercising prudence is crucial when handling any form of poison or gas to kill moles or gophers, as improper use can result in danger and long-lasting environmental consequences. 

Just remember that safety should always be priority number one when working with combustible materials such as propane!
