So, when we notice stunted growth, yellowing leaves, or even death in our beloved greenery, it can be a cause for perplexity and concern. One possible culprit for this damage may be the presence of moles. These small, burrowing mammals can wreak havoc on plant roots and tree health, often going unnoticed until it’s too late. In this article, we’ll explore the behavior of moles, the signs of their damage, methods for controlling them, and preventative measures to keep them at bay. By understanding the impact that moles can have on your plants and trees, you’ll be better equipped to maintain their health and beauty.
Understanding Moles and Their Behavior
It’s essential to understand the behavior of moles when it comes to controlling the damage to your garden and trees. Moles are small, burrowing mammals that can wreak havoc on your lawn and landscape. They tunnel through the soil in search of insects and earthworms, which are their primary source of food. Knowing how moles behave and identifying their presence can help you prevent further damage. This knowledge is crucial for implementing effective control methods and protecting your plants and trees from the harm that moles cause. To learn more about identifying mole damage and preventing harm to your plants and trees, check out our articles on identifying mole damage and preventing mole damage.
Identification of Moles
Identification of Moles
- The most common species of moles include the eastern mole, star-nosed mole, hairy-tailed mole, coast mole, broad-footed mole, and Townsend’s mole.
- Moles have cylindrical-shaped bodies that are covered in velvety fur. They have small eyes and ears that are usually hidden within their fur. Their front feet are wider than their back feet and are shaped like shovels to aid in digging.
- The tunnels created by moles can be identified by the raised ridges or molehills that appear on the surface of the ground. Molehills are small mounds of soil that are pushed up from deeper burrowing activity. The ridges are caused by the tunnels just below the soil surface that follow their search for food.
- Many people mistake mole damage as the work of voles or gophers. Unlike voles, moles are solitary creatures, and their tunnels are much larger in diameter with fewer holes. Gophers are more likely to create mounds of dirt.

Moles Tunneling and Feeding Habits
Moles are small, burrowing mammals that can quickly wreak havoc on plant roots and the health of surrounding trees. These creatures are known for their distinctive tunneling and feeding habits.
Tunneling Habits: Moles create an extensive network of tunnels beneath the ground. They dig at an impressive rate, tunneling up to 18 feet per hour, and can create a maze of tunnels that crisscross and connect in all directions. These tunnels can often be identified by the characteristic raised ridges of soil that run along the ground’s surface.
Feeding Habits: While tunneling, moles search for insects, earthworms, and other invertebrates in the soil. Their primary diet consists of insects and grubs and their feeding habits leave behind small tunnels and cavities within the soil. This can lead to damage to plant roots as the moles break up the soil and disrupt rooting patterns.
Moles can sometimes be beneficial as they help to reduce insect populations in the soil. However, when their tunneling habits turn destructive, their feeding habits can become an issue for plants and trees in the area.
Understanding the behavior of moles is vital in controlling and minimizing damage to plants’ roots and neighboring trees. There are various methods to combat mole damage to garden and orchard, restore the landscape design, repair plants and trees, and improve soil health and nutrition, which are discussed in detail in other parts of this article.
Signs of Mole Damage to Plant Roots and Trees
It can be frustrating to watch plants and trees that you’ve worked hard to care for become damaged. Moles are small, but their impact on plant roots and trees can be significant. If left unchecked, their tunneling and feeding habits can cause stunted plant growth, root system damage, and subsequent invasions by pests and disease. Knowing the signs of mole damage is crucial for taking action and protecting your garden or orchard. In this section, we will explore the effects of mole damage on plant roots and trees, and discuss techniques for repairing the damage. To learn more about preventing mole damage, check out our earlier section on moles, soil health, and plant nutrition.
Plant Growth Stunting and Death
When moles tunnel through the soil, they can cause damage to the root system of plants and trees. This damage can result in plant growth stunting and death. When the roots of plants and trees are damaged, they are not able to absorb enough water and nutrients to support healthy growth. This can lead to yellowing, wilting, and eventual death of the plant.
In addition to affecting the overall health of plants, moles can also damage the roots of specific plants. For example, they can damage the roots of newly planted seedlings, causing them to die before they have a chance to mature. They can also damage the roots of fruit trees and shrubs, which can cause a decline in the health and productivity of these plants.
Damage to the root system can weaken plants and trees, making them more susceptible to other types of damage. Invasions by plant pests and disease can occur more frequently in plants that have been weakened by mole damage. This can lead to a vicious cycle where moles damage the roots of plants, making them more susceptible to other types of damage, which in turn makes them more vulnerable to mole damage.
To prevent moles from causing damage to plant roots and ultimately leading to plant death, it is essential to take appropriate measures. For instance, controlling mole populations through the use of physical barriers, repellents, or traps can prevent them from further burrowing and tunneling. You can also take steps to prevent mole damage by eliminating their food sources and keeping soil and lawns healthy.
If you notice damage to the roots of your plants or trees, it is important to take action right away to prevent further damage. Repair techniques for mole damage to plants and trees are available and can be found at /mole-damage-repair-techniques-plants-trees/. By identifying and addressing the problem, you can help protect the health and longevity of your plants and trees.
Root System Damage and Stress
Roots play a significant role in the plant’s health as they are responsible for taking up water and nutrients from the soil. However, mole activity can cause damage to the root system, and this can result in multiple problems.
Moles dig tunnels underground, and this movement can disturb the structure of delicate root systems. When roots are damaged, it can inhibit the plant’s ability to absorb water and nutrients from the soil. As a result, the plant will start to experience stress, exhibit dry or yellow leaves, and will not grow properly. In severe cases, root damage can also lead to plant death.
A damaged root system can also create open wounds for plant pathogens and other pests to enter. As a result, it can lead to subsequent invasions by harmful insects, such as grubs, and soil-borne diseases like Pythium or Fusarium wilt. This additional damage to the plant will cause further stress and can reduce crop yields, resulting in a significant economic loss.
It is crucial to detect and prevent root damage by moles as soon as possible. One can detect the damage by observing the plant’s growth rate and health regularly, and proper control measures must be taken. To learn about the methods that can be used to combat mole damage to plant roots and trees, one can read our article on combating mole damage to the garden and orchard.
Root damage can also impact the aesthetics of the lawn or landscape. To learn more about how mole damage can affect the landscape design, one can read our article on mole damage in landscape design. Also, to understand how moles influence plant growth, one can read our article on moles and plant growth.
Subsequent Invasions by Plant Pests and Disease
When moles damage plant roots, they create an entry point for various plant pests and diseases to invade the weakened roots. Invasive species such as aphids, mites, and beetles may enter and damage the roots, leading to further plant stress and potential death.
When roots are damaged, underground fungal diseases can easily take hold and spread due to weakened root systems. This can cause diseases such as Fusarium and Phytophthora to spread and kill the plant.
The table below illustrates some of the common plant pests and diseases that can invade plant roots subsequent to mole damage.
| Pest/Disease | Symptoms | Treatment |
|---|---|---|
| Aphids | Curling and twisting of leaves, stunted growth, yellowing | Use insecticidal soap or neem oil |
| Mites | Fine webbing on leaves, yellow or brown spots, stunted growth | Use miticide or neem oil |
| Beetles | Holes in leaves, wilting, defoliation | Use insecticidal spray or trap |
| Fusarium | Yellowing and wilting of leaves, stunted growth, root rot | Use fungicide or remove infected plant debris |
| Phytophthora | Browning and wilting of leaves, root rot, stunted growth | Use fungicide or remove infected plant debris |
It is crucial to address mole damage promptly to prevent further damage from invasive plant pests and diseases. Proper preventive measures and timely control and treatment can help preserve your garden and lawn’s health.
Methods for Controlling Moles
