Moles and Their Damages
Moles are active creatures that can create chaos in your well-manicured lawn or garden. If you’re puzzled about how to deal with these burrowing pests, there are several options available for mole control. But before that, it’s important to have a solid understanding of these small mammals and their potential for destruction. In this section, we’ll delve into the characteristics of moles, the damages they can cause, and the best ways to control them using chemical repellents.
What are moles?
Moles are small, burrowing mammals that are commonly found in gardens and lawns. They belong to the Talpidae family and are known for their cylindrical bodies, small eyes, and large front paws that are designed for digging. There are several species of moles, including the Eastern mole, the Star-nosed mole, and the Hairy-tailed mole. One of the most common species in North America is the Eastern mole (source).
Here is a table summarizing the key characteristics of moles:
| Characteristics | Description |
|---|---|
| Size | Moles are typically 4-9 inches long and weigh about 2-6 ounces |
| Habitat | Moles live underground in burrows and tunnels |
| Diet | Moles primarily eat insects, earthworms, and other small animals found underground |
| Behavior | Moles are solitary animals that are active year-round. They are most active during the spring and fall months |
| Reproduction | Female moles give birth to litters of 2-7 pups each spring |
Moles are not harmful to humans, but they can cause significant damage to lawns and gardens. It is important to understand their behavior and habitat in order to effectively control them (source).
Characteristics of moles
Moles are small, burrowing mammals that belong to the family Talpidae. They have several distinct characteristics that differentiate them from other mammals. These characteristics include:
- Fur: Moles have a dense, velvety fur that is usually dark gray or black in color. The fur is well-suited to their underground lifestyle as it provides insulation and helps them move through the soil.
- Body: Moles have a cylindrical body shape with short, powerful legs and large, spade-like front paws that are specially adapted for digging. Their eyes and ears are small and are buried in their fur to protect them from dirt and debris.
- Diet: Moles are primarily insectivorous, and their diet consists mainly of earthworms, grubs, and other soil-dwelling insects. Their saliva contains a toxin that paralyzes their prey, making it easier to catch and eat.
- Behavior: Moles are solitary and are active year-round, although they are most active in the spring and fall. They create complex underground tunnels and burrows that can extend for several hundred feet. They are also excellent swimmers and can move through water by paddling with their front paws and using their tails as rudders.
- Reproduction: Moles typically breed in the winter, and females give birth to litters of 2-7 young in the spring. The young remain underground for several weeks before venturing to the surface.
Understanding these characteristics is important for effective mole control. By using appropriate repellents, homeowners can safely and effectively eliminate moles from their lawns and gardens.

How Do Chemical Repellents Work?
Have you ever wondered how chemical repellents deter moles from damaging your lawn and garden? It may seem like magic, but there is actually science behind it. Chemical repellents work by producing odors or flavors that are unpleasant to moles. The type of repellent used determines how the repellent works and how effective it is. Let’s take a closer look at how some of the most common chemical repellents on the market work to keep moles away from your property.
How castor oil-based repellents work?
Castor oil-based repellents are one of the most popular organic repellents that work by creating a taste and odor aversion to the moles. The active ingredient in castor oil-based repellents is castor oil, which is a natural vegetable oil extracted from castor bean seeds.
Here is how castor oil-based repellents work:
- When applied to the soil, castor oil-based repellents cause the soil to become unpleasant and tasteless for the moles.
- The taste and odor created by the natural oil makes the soil unappealing to the moles, and they start to look elsewhere for food.
- The strong scent of castor oil can also confuse the moles’ sensory system, causing them to become disoriented and uncomfortable.
- Eventually, the moles are forced to leave the area and scavenge elsewhere for food and shelter.
It is important to note that castor oil-based repellents do not kill moles. Instead, they act as a deterrent by making the soil less attractive to them. The repellents are generally recognized as safe and non-toxic to humans, pets, and the environment.
How aluminum sulfate-based repellents work?
Aluminum sulfate-based repellents work by irritating the moles’ sense of smell and taste. The repellent contains a high amount of aluminum sulfate, which is a chemical compound that produces a pungent odor that the moles find unpleasant. When the repellent is applied to the soil, it creates an unpleasant environment for the moles, causing them to leave the area.
The working of aluminum sulfate-based repellents can be explained in three steps:
- Identification of the problem: The first step in using aluminum sulfate-based repellents is to identify the presence of moles in your lawn or garden. Look for raised ridges or mounds of soil on your property. These are signs of mole activity.
- Application of the repellent: Once you have identified the problem, the next step is to apply the aluminum sulfate-based repellent according to the product label. The product may come in a granular or liquid form. The granular form is usually applied by hand or with a spreader, while the liquid form is applied using a garden hose sprayer. The repellent should be applied to the affected area and watered in immediately to ensure that it reaches the soil.
- Result: The aluminum sulfate-based repellent will irritate the moles’ sense of smell and taste, causing them to leave the area. It may take a few days for the repellent to take effect, as the moles will need to be exposed to it repeatedly before they are repelled. However, with regular application and perseverance, the repellent can effectively control mole activity in your lawn or garden.
Some key points to keep in mind when using aluminum sulfate-based repellents for mole control include:
- It is important to apply the repellent according to the product label, as over-application can harm plants and runoff can cause environmental damage.
- Reapplication of the repellent may be necessary, as it can be washed away by rain or irrigation.
- While aluminum sulfate-based repellents are generally safe for humans and pets, they can be harmful if ingested. It is important to keep children and pets away from the treated area until the repellent has dried.
- Aluminum sulfate-based repellents may not be as effective in heavy clay soils, as the repellent may not penetrate the soil deeply enough to reach the moles.
Aluminum sulfate-based repellents can be an effective option for controlling moles in your lawn or garden. However, it is important to use the product properly and to be patient, as it may take some time for the repellent to take effect.
How allium-based repellents work?
Allium-based repellents consist of compounds derived from plants in the Allium genus, such as garlic and onions. These compounds contain a strong odor that repels moles. Here’s how allium-based repellents work:
1. The odor overwhelms the mole’s senses.
Moles rely heavily on their sense of smell to navigate and find food. The strong odor of allium-based repellents overwhelms their sense of smell making it difficult for them to locate food and navigate their burrows.
2. The odor irritates the mole’s nasal passages and eyes.
The compounds in allium-based repellents can irritate the nasal passages and eyes of moles, making it uncomfortable for them to stay in an area where the repellent has been applied. This can cause the mole to look for a new area to dig its burrow.
3. The odor lingers in the soil.
Allium-based repellents do not evaporate quickly and their odor lingers in the soil for an extended period of time. This means that moles are less likely to return to an area where the repellent has been applied, making it a more long-term solution.
However, it’s important to note that allium-based repellents can also repel other beneficial animals, such as earthworms, from the soil. Overuse of allium-based repellents can also lead to a buildup of the compounds in the soil, making it less effective over time. It’s important to follow the product instructions carefully and not to overapply.
How to Properly Use Chemical Repellents?
When it comes to using chemical repellents for controlling moles, it is important to do it properly to ensure maximum effectiveness. The key is to properly identify the mole tunnels and surface runways and apply the repellents according to the product label instructions. Over-application and runoff should be avoided, and the repellents should be reapplied regularly. In this section, we will discuss the step-by-step process of how to use chemical repellents for moles control.
Identify the mole tunnels and surface runways
Identifying the mole tunnels and surface runways is the crucial first step before applying any chemical repellents for moles control. Here are a few tips on how to accurately identify them:
