Killing Moles With Marshmallows: Is It Possible?

Moles can be a significant nuisance to homeowners and gardeners alike. These small, insectivorous mammals are notorious for the damage they cause to lawns and gardens as they dig extensive tunnels in search of their primary food source, earthworms. Controlling mole populations can be challenging, and traditional methods such as traps, repellents, and poisons often prove to be ineffective or harmful to the environment. This article explores an unconventional method that has gained attention in recent years: killing moles with marshmallows. We will examine the origins of this technique, its effectiveness, safety concerns, and ethical considerations while providing expert opinions and recommendations.

The Marshmallow Method

A. Origins of the Marshmallow Method

The marshmallow method of mole control first emerged as anecdotal evidence shared among homeowners and gardeners who were looking for non-toxic alternatives to traditional mole control methods. Its popularity grew as people searched for more environmentally friendly and humane ways to deal with moles.

B. How the Marshmallow Method Works

The marshmallow method involves placing marshmallows in active mole tunnels, which moles will then consume. The idea is that moles are unable to digest marshmallows properly, leading to their eventual demise. Proponents of this method claim that it can effectively reduce mole populations without the use of harmful chemicals or traps.

Analyzing the Marshmallow Method

A. Effectiveness

  1. Available research and studies: Scientific research on the marshmallow method is limited. However, anecdotal evidence from homeowners and gardeners suggests varying degrees of success.
  2. Comparing success rates with traditional methods: While some people report success with the marshmallow method, it is difficult to determine its effectiveness compared to conventional mole control techniques. Further research is needed to provide a definitive answer.

B. Safety Concerns

  1. Potential risks to other wildlife: One of the primary concerns with the marshmallow method is the potential risk it poses to other wildlife, such as birds or small mammals, that might consume the marshmallows. There is also the possibility that domestic pets may ingest the marshmallows, leading to digestive issues.
  2. Possible impact on the environment: As marshmallows are not a natural part of the ecosystem, there is a potential for negative environmental effects. However, these impacts are likely minimal compared to the use of chemical poisons.

C. Ethical Considerations

  1. Humane treatment of moles: Some people argue that the marshmallow method is inhumane because it causes moles to suffer from indigestion and possibly death. Others contend that it is a more compassionate approach than traps or poisons, which can cause significant pain and suffering.
  2. Alternative methods for controlling mole populations: It is essential to consider other non-lethal mole control methods, such as installing barriers or using repellents, which may be more humane and effective in the long term.

Expert Opinions and Recommendations

A. Pest Control Professionals

  1. Their experiences with the marshmallow method: Pest control professionals have varying opinions on the marshmallow method, with some reporting success and others claiming it is ineffective. Many experts recommend a combination of approaches for the best results.
  2. Recommendations for mole control: Pest control experts generally advise using a multi-pronged approach to control moles, including trapping, repellents, and habitat modification.

B. Wildlife Biologists and Ecologists

1. Assessing the impact on the ecosystem

Wildlife biologists and ecologists emphasize the importance of understanding the potential impacts of any mole control method on the ecosystem. While the marshmallow method may pose some risks to other wildlife, it is generally considered less harmful than chemical poisons.

2. Suggestions for environmentally friendly mole control

Wildlife experts often recommend using environmentally friendly mole control methods, such as the following:

  • Habitat modification: Reducing the availability of mole food sources, like grubs and earthworms, by using organic lawn care practices and promoting a diverse ecosystem.
  • Physical barriers: Installing underground barriers around gardens or other areas where mole activity is undesirable.
  • Repellents: Using natural, non-toxic mole repellents, such as castor oil-based products, to deter moles from specific areas.

DIY Mole Control with Marshmallows

A. Step-By-Step Guide

  1. Identifying active mole tunnels: To effectively use the marshmallow method, it is essential first to identify active mole tunnels. Look for raised ridges or mounds of soil in your yard, and gently press down on the ridges to collapse a small section of the tunnel.
  2. Placing marshmallows in the tunnels: After 24 hours, check for the tunnels that have been repaired, indicating mole activity. Carefully dig a small hole in these tunnels, place one or two marshmallows inside, and then cover the hole.
  3. Monitoring results and adjusting the method: Keep an eye on mole activity and continue placing marshmallows in active tunnels as needed. Be prepared to adjust your approach or combine it with other methods if you do not see the desired results.

B. Tips for Success

  1. Combining the marshmallow method with other strategies: For the best results, consider combining the marshmallow method with other mole control techniques, such as traps or repellents.
  2. Patience and persistence: Successfully controlling mole populations can take time and effort. Be patient and persistent in your efforts, and remember that it may take several weeks or even months to see a significant reduction in mole activity.


In conclusion, the marshmallow method for mole control is a controversial and unconventional technique with varying degrees of reported success. While it may be less harmful to the environment than chemical poisons and more humane than some traps, it is essential to weigh the potential risks to other wildlife and the effectiveness of the method. Pest control professionals and wildlife experts recommend a multi-pronged approach to mole control, including habitat modification, physical barriers, and the use of natural repellents. Ultimately, it is up to each homeowner or gardener to decide whether the marshmallow method is an appropriate and effective solution for their mole problem.
