What are Mole Fumigants?

What Are Mole Fumigants?
It can be frustrating to deal with moles that ruin your lawn and garden. Mole fumigants are one solution to this problem. They are chemicals designed to kill moles and other burrowing rodents that cause damage to your lawns and gardens. Before using mole fumigants, it is important to be aware of their types, how they work, and safety precautions associated with them. You can read more about this in our Understanding Mole Fumigants section.

Types of Mole Fumigants

There are two main types of mole fumigants: smoke bombs and gas cartridges. Here are the details about each type:

Type of Mole Fumigant Description
Smoke bombs As the name suggests, these fumigants produce smoke that suffocates the moles. Smoke bombs contain aluminum phosphide, which reacts with air and water vapor to produce phosphine gas. Aluminum phosphide is highly toxic and must be used with caution.
Gas cartridges These are small canisters filled with a gaseous fumigant such as carbon monoxide. The gas is released when the cartridge is ignited. Gas cartridges work by displacing oxygen from the soil, which causes the moles to suffocate. Gas cartridges are a less toxic alternative to smoke bombs but still require careful handling.

It’s important to note that mole fumigants should only be used in accordance with their instructions and with the proper safety precautions. For more information about safety considerations when using mole fumigants, see our article on Mole Fumigant Safety.

Finally, if you have any questions about mole fumigants, we’ve compiled a list of frequently asked questions at Mole Fumigant FAQs.

How Do They Work?

Mole fumigants work by releasing poisonous gas that eliminates moles from lawns and gardens. There are two types of mole fumigants: smoke bombs and gas cartridges.

Smoke Bombs are ignited and placed in mole burrows. They release toxic fumes that penetrate the soil and enter the mole’s burrow, killing the mole. They can be purchased at garden supply stores or online.

Gas cartridges are also inserted into mole tunnels but work differently from smoke bombs. The cartridges contain aluminum phosphide, which reacts with moisture in the soil to release a lethal gas that quickly kills moles.

Both smoke bombs and gas cartridges require careful handling and safety considerations. It’s important to follow the instructions on the package and use protective equipment, such as gloves and a mask.

Mole fumigants work best when the soil is moist, as the gas moves through the soil more easily. In dry conditions, the gas can dissipate into the air rather than staying in the soil, reducing its effectiveness.

It’s also essential to seal the mole’s burrow once the fumigant has been inserted to prevent the gas from escaping. If the gas escapes, it can be harmful to people or other animals in the area.

Mole fumigants can be an effective way to eliminate moles from your lawn, but it’s critical to use them safely and correctly.

Safety Considerations

When using mole fumigants, it is essential to take safety precautions to prevent damage to the environment, lawns, and potential harm to humans and pets. Here are some safety considerations to keep in mind:

  • Always wear gloves and protective clothing when handling mole fumigants.
  • Use a mask or respirator to avoid inhaling toxic chemicals.
  • Avoid eating, drinking, or smoking when applying mole fumigants. Wash hands before and after use.
  • Keep children and pets away from the treated area until it is safe to return.
  • Do not apply mole fumigants near water bodies, as they may contaminate nearby aquatic life.
  • Read and follow the label directions carefully. Overexposure or misuse of mole fumigants can be dangerous.
  • Dispose of empty containers, unused baits, and contaminated items as directed on the label. Do not burn or reuse them.
  • If accidental ingestion or exposure occurs, seek immediate medical attention.

When using mole fumigants, it is crucial to handle them with care and follow the instructions provided to ensure your safety and others around you.

Step Action
1. Wait the recommended amount of time before removing the fumigant. This will usually be indicated on the product label.
2. Once the fumigant has been removed, check for any remaining mole activity. This can be done by looking for new mounds or tunnels in the lawn.
3. If mole activity is still present, consider applying a second round of fumigant or using alternative methods of mole control.
4. Take steps to prevent future mole infestations by making sure the lawn is properly maintained, removing any sources of food for moles (such as grubs), and using exclusion techniques (such as barriers) to keep moles out of the lawn.
5. Monitor the lawn regularly for any signs of mole activity, and take action as soon as any activity is detected.

Following these steps will help ensure that your lawn remains free of mole infestations and that you have successfully controlled any existing mole populations. Remember to always read product labels and follow all safety precautions when applying mole fumigants or any other type of pest control product.

Alternatives to Mole Fumigants

If you’re not comfortable using mole fumigants in your lawn, there are other alternatives available. These options are generally safer for both you and the environment, but may require more time and effort to implement. Here are some alternative mole control methods that you can consider.

Mole Repellents

Mole repellents are a good alternative to using fumigants, and they work by creating an unpleasant environment for moles to discourage them from nesting beneath your lawn. Here are some of the most popular mole repellents:

  • Castor Oil: This is one of the most effective natural mole repellents. It works by coating the moles’ food source, earthworms, with castor oil, which makes them difficult for the moles to digest, and forces them to find food elsewhere.
  • Peppermint: Moles have a heightened sense of smell, and peppermint is particularly offensive to them. By placing peppermint oil or peppermint plants near mole activity, you can create an unappealing environment for the moles.
  • Ultrasonic devices: These devices emit high-frequency sound waves that are unpleasant for moles, and create an uncomfortable environment for them. Ultrasonic devices are eco-friendly and safe to use, making them a popular choice for homeowners who want to avoid using chemicals on their lawns.

It’s important to note that while mole repellents can be effective in the short-term, they are not a long-term solution for mole infestations. Some repellents may not work for all types of moles, and it may be necessary to try a combination of different repellents to find one that works effectively for the specific type of mole infestation you’re dealing with.

Exclusion Techniques

Exclusion techniques refer to methods that do not involve killing or harming moles but instead focus on preventing them from entering your lawn in the first place. These techniques typically involve physical barriers or modifications to the landscape. Here are some exclusion techniques you may consider:

Technique Description
Barrier Installation Installing barriers around your lawn is a highly effective way of preventing moles from entering. Barriers can be made of materials such as mesh, wire, or rocks. They are typically buried a few inches below the ground and rise a few inches above it. If you choose to install a barrier, make sure it is buried deep enough as moles are excellent diggers.
Planting Planting trees or shrubs that moles do not like can help prevent them from entering your lawn. Some plants that deter moles include daffodils, alliums, and fritillaries. Avoid planting things like tulips and crocuses as these are some of moles’ favorite foods.
Keeping Your Lawn Dry Moist soil is easier for moles to dig through. By watering your lawn less frequently and focusing on deep watering instead of light watering, you can help create conditions that are less favorable for moles. Additionally, ensuring proper drainage in your lawn prevents the soil from becoming too moist.
Burrowing Prevention Moles often enter lawns through existing burrows, such as those created by rodents. By eliminating these burrows, you can prevent moles from entering your lawn. Fill in any holes you find and place rocks or other obstacles over any areas where rodents typically burrow.

While exclusion techniques can be effective, they require ongoing effort and may not be practical for everyone. In cases of severe mole infestations, exclusion techniques alone may not be enough, and other methods like fumigation may be necessary.

Lawn Care Practices

Maintaining a healthy lawn is key to preventing mole infestations. By following good lawn care practices, homeowners can significantly reduce the likelihood of moles invading their lawns. Here are some important lawn care practices to follow:

  • Maintain Proper Mowing Height: Keeping the grass at the recommended height for the type of grass in your lawn promotes a healthy growth, which provides a less favorable habitat for mole burrowing.
  • Watering: Proper and consistent watering ensures that the lawn’s root system is healthy and deep. This jostles the soil, making it more difficult for moles to access the earthworms, grubs, and other insects that live within it.
  • Fertilization: Proper and timely fertilization ensures that the grass is well-nourished, which makes it less of a target for insect activity. This reduces the likelihood of mole activity in the lawn.
  • Soil Management: Soil plays a significant role in maintaining healthy grass. Ideally, the soil pH should be between 6.0 and 7.0, with the nutrients that grass needs to thrive. If the soil quality is poor, aerating the lawn, adding organic matter or lime will help to promote healthy growth, keeping the soil healthy and hindering mole activity.
  • Reduce Attractants: Allowing food sources such as insect or grubs to grow and remain in the soil attracts moles to burrow in the lawn. Physical removal of potential food sources eliminates one of the key reasons moles enter your lawn.
  • Regular Maintenance: Keeping the lawn properly maintained, for instance, reducing leaf litter, debris, and ensuring weeds do not take root on your lawn, provides the mole with fewer burrowing opportunities. Keep the lawn tidy, fixing bare patches as soon as possible, and maintaining a healthy lawn will make burrowing more challenging for these creatures.

With these proper lawn care practices, homeowners can keep their lawn free of mole activity and prevent these pesky critters from infesting their lawn.


In conclusion, it’s important to consider various options before deciding to apply mole fumigants in your lawn. Mole fumigants can be effective in getting rid of mole infestations, but they also come with safety considerations and potential environmental impacts. Before applying mole fumigants, it’s important to identify the signs of mole infestation and choose the right time for application.

If using mole fumigants, it’s crucial to follow the instructions carefully and take appropriate safety precautions such as wearing gloves and washing hands thoroughly afterwards.
