What is Chemical Mole Exclusion?
Protecting a beautiful garden or lawn involves looking after its health and warding off pests that threaten to damage it. Moles can be a major problem for gardens and yards, causing damage to plants and disrupting soil structures. One of the methods used for controlling and preventing moles is Chemical Mole Exclusion. This method involves the use of various chemicals to repel or kill moles. However, while it may be effective, Chemical Mole Exclusion also poses potential risks to the environment and other organisms. Before using this method, it’s important to understand what it is, how it works and weigh its pros and cons.
What are the Common Chemicals Used in Mole Exclusion?
Chemical mole exclusion is a method used to control mole populations in gardens, lawns, and other outdoor spaces. There are several common chemicals used in mole exclusion, including zinc phosphide, bromethalin, and chlorophacinone. These chemicals are typically used in the form of baits, which are placed in mole tunnels or runways.
| Chemical | Usage |
|---|---|
| Zinc phosphide | Used as a rodenticide to kill moles and other rodents |
| Bromethalin | Used as a neurotoxin to kill moles and other rodents |
| Chlorophacinone | Used as an anticoagulant to kill moles and other rodents |
It is important to note that the use of these chemicals can have negative impacts on the environment and other wildlife. If not used properly, these chemicals can harm beneficial organisms such as earthworms, birds, and other small mammals. It is also important to follow all product instructions carefully to ensure safe and effective use.

How Does Mole Exclusion Work?
Mole exclusion works by using chemical products to repel moles from lawns and gardens. These products are designed to create an unpleasant environment for these pests, which then drives them away from the treated area. The chemicals used in mole exclusion are typically applied to the soil or plants near the mole activity.
The chemicals used in mole exclusion work in different ways. Some products contain castor oil, which is believed to create a strong odor moles find offensive. Other products use chemicals such as aluminum sulfate or ammonium lactate, which acidify the soil and make it difficult for moles to dig. Moles are unable to tolerate acidic soil and will avoid areas with these conditions.
Once applied, the chemicals in mole exclusion products can last for several months. However, these products may need to be reapplied if mole activity persists or new activity is found. It’s important to follow the manufacturer’s instructions carefully and not to exceed the recommended application rates.
While chemical mole exclusion can be effective in controlling moles, it’s important to note that it can also have negative impacts on the environment. These impacts include soil and plant damage, harm to beneficial organisms such as earthworms, and potential risks to wildlife. It’s important to consider alternatives to chemical mole exclusion before using these products.
The Effects on Soil and Plants
It is important to consider the impact of chemical mole exclusion on the environment, particularly on the soil and plants. While chemical solutions can effectively remove moles, there are potential negative effects that should not be overlooked. Chemicals used in mole exclusion can affect the health of the soil and plants, as well as the beneficial organisms living within it. However, it is also important to acknowledge that there are alternative methods that can be just as effective in controlling in mole populations.

One alternative to chemical mole exclusion is the use of natural mole control methods. These methods are not harmful to the environment and are often less expensive than chemical treatments.
Table of Natural Mole Control Methods
| Method | Description |
|---|---|
| Castor Oil | Applying castor oil to the areas where moles are present can help deter them from digging. The strong odor and taste of the oil is not appealing to moles, causing them to move on to a new area. |
| Vibrating Devices | Using vibrating devices, such as solar-powered mole repellers, can help deter moles from digging in your yard. These devices emit vibrations that simulate the presence of predators, keeping moles away. |
| Natural Predators | Encouraging natural predators, such as owls and hawks, to visit your yard can help control the mole population. These birds of prey will hunt for moles and other small rodents, keeping their populations in check. |
| Fencing | Installing an underground fence made of mesh or wire can prevent moles from entering your yard. By placing the fence at least 1-2 feet below the ground and extending it several inches above ground level, moles will not be able to tunnel under or climb over it. |
It’s important to note that natural mole control methods may take longer to show results than chemical treatments. It’s also possible that these methods may not completely eliminate the mole population in your yard. However, if used consistently and in combination with preventative measures, natural mole control methods can be an effective solution for managing mole activity without causing harm to the environment.
Preventative Measures
To prevent mole infestations, there are various preventative measures that can be taken. These measures aim to make an area less attractive to moles and deter them from taking up residence. Here are some effective preventative measures:
| Preventative Measures | Description |
|---|---|
| Proper Lawn Care | Regularly mowing and watering the lawn will keep it healthy and reduce the likelihood of mole tunnels forming. Moles prefer moist, loosely packed soil, so maintaining a drier yard can help deter them. |
| Remove Food Sources | Removing sources of food for moles can reduce their presence. This can include removing grubs and insects, which moles feed on. Applying insecticide to the lawn can help reduce the number of insects and subsequently, moles. |
| Physical Barriers | Placing barriers such as rocks, wire mesh, or gravel around plants can make it more difficult for moles to access them. This can also be applied around the perimeter of the yard. |
| Plant Barriers | Planting certain types of plants that moles do not like, such as daffodils, alliums or marigolds, can act as a natural deterrent. Alternatively, planting fruits and vegetables in raised beds can make them more difficult to access. |
| Ultrasound Repellents | Ultrasound devices emit a high-frequency sound that humans cannot hear but is unpleasant for moles. These devices can be installed in the yard to discourage moles from entering the area. |
By implementing these preventative measures, you can reduce the risk of a mole infestation while protecting the environment. It is important to remember that these measures may not entirely eliminate the presence of moles, but they can certainly discourage them from taking up residence in your yard.
Professional Mole Control Services
Professional mole control services are a valuable option for individuals who prefer not to use chemicals and for those facing severe or persistent mole infestations. These services typically involve the use of humane methods to trap and remove the moles without causing harm to them.
One of the methods used by professional mole control services is the use of traps. There are various types of traps available, including live traps, which allow the moles to be caught alive and released elsewhere. Another commonly used method is the use of barrier methods, where devices such as wire mesh are buried in the ground to prevent access to areas where moles are not wanted.
Professional services also offer inspections to determine the extent of the mole problem and identify the most effective treatment options. Follow-up inspections may also be necessary to ensure the mole population has been adequately controlled.
While professional mole control services may be more costly than chemical exclusion methods or natural mole control methods, they are often the most effective solution for persistent or severe infestations. Additionally, by using humane and sustainable methods, they are environmentally friendly and have minimal impact on beneficial organisms and the ecosystem as a whole.
Professional mole control services provide a safe and effective way to control mole infestations without using harmful chemicals or causing harm to the environment.
