February 11, 20236 min read

Introduction to voles in Pennsylvania:

As you look around your garden or yard, one of the most common sights is that of a small rodent scurrying away from view. While it may not be immediately obvious, these little creatures play an important role in Pennsylvania's ecosystem. This article will provide an overview of voles and their significance to the state’s environment. We will explore their biology and behavior, the impact they have on the state’s ecosystem, and methods for managing and controlling their populations. Through understanding the importance of these small rodents, we can learn to appreciate them instead of viewing them as pests.

Voles, also known as meadow mice or field mice, are small rodents that are native to Pennsylvania. There are several species of voles found in the state, including the meadow vole, pine vole, and the masked vole. These tiny creatures are often overlooked, but they play an important role in the state's ecosystem. In this article, we will take a closer look at voles in Pennsylvania, exploring their biology and behavior, the impact they have on the ecosystem, and methods for managing and controlling their populations.

Vole Biology and Behavior

Voles are small, stocky rodents that have a dense, soft fur, small eyes, and rounded ears. They range in size from 6 to 9 inches in length and weigh between 1 to 2 ounces. Voles are found in a variety of habitats, including fields, meadows, forests, and wetlands. They feed on a variety of plants, including grasses, roots, and seeds, and they have a high metabolism that requires them to consume a large amount of food each day. In addition to their plant-based diet, voles also eat insects, snails, and other small creatures, making them omnivores.

Voles are social creatures that live in burrow systems and often share their tunnels with other voles. Their burrow systems can be extensive, with multiple tunnels and chambers, and they can reach depths of up to 3 feet. Voles are active throughout the year, but they are most active during the autumn and winter months. During this time, they are more likely to venture above ground in search of food. Voles reproduce quickly and often, with females capable of producing several litters each year. A single vole population can grow quickly, and without proper control measures, their populations can become unmanageable.

Impact of Voles on Pennsylvania's Ecosystem

Voles play a significant role in Pennsylvania's ecosystem, both as herbivores and as prey for predators. Their feeding habits can have a significant impact on crops and gardens, as they are known to feed on the roots of plants and can cause extensive damage. In agricultural areas, voles can be a major problem for farmers, causing damage to crops and reducing yields. In addition to damaging crops, voles can also impact the health of trees and shrubs, by girdling the roots and trunk, and making them more susceptible to disease and damage from other pests.

Voles are also important prey for predators such as snakes, birds of prey, and carnivorous mammals, and they play a role in maintaining the balance of the food chain. By providing a source of food for these predators, voles help to control their populations and prevent them from becoming too abundant.

Voles also impact the native flora and fauna in Pennsylvania by creating tunnels and burrows that provide shelter for other small animals, such as insects and amphibians. These burrows also play a role in aerating and enriching the soil, which can benefit native plants. In addition, voles can help to distribute seeds and other plant material throughout the landscape, allowing for new plant growth and expansion.

Vole Management and Control

Preventing vole damage in crops and gardens is important for maintaining healthy plant growth and for preserving the health of Pennsylvania's ecosystem. There are several methods for managing and controlling vole populations, and each has its own advantages and disadvantages.

Exclusionary methods are often the first line of defense for preventing vole damage. Gardeners can protect their plants by using wire mesh or plastic tree guards, which prevent voles from accessing the roots of the plants. These methods are simple and cost-effective, and they are also relatively easy to install. However, they can be time-consuming, and they may not be suitable for large gardens or farms.

Habitat modification is another method for preventing vole damage. Farmers can protect their crops by using crop rotation and planting cover crops, which help to break up vole habitats and reduce the likelihood of damage. By planting cover crops, farmers can also improve the fertility of the soil and increase the diversity of the ecosystem. This method is especially effective when combined with other vole management strategies.

For homeowners, vole control methods include using vole repellent sprays, trapping, and using physical barriers to prevent access to plants. Vole repellent sprays contain natural ingredients that are unpleasant to voles, and they can be used to protect individual plants or entire gardens. This method is simple and easy to use, and it does not require any special equipment. However, the effectiveness of vole repellent sprays can vary depending on the size of the garden and the severity of the vole problem.

Trapping is another option for controlling vole populations, and it can be an effective way to reduce vole numbers. There are several types of vole traps available, including live traps, snap traps, and glue traps. When using traps, it is important to place them in areas where voles are known to be active and to check them regularly. Trapping is a humane way to control vole populations, and it does not harm the environment. However, it can be time-consuming, and it requires some patience and persistence.

Physical barriers are another effective way to prevent vole damage. By using barriers, such as fencing or mulch, homeowners can protect their plants from vole damage. This method is especially useful for small gardens and for individual plants, and it is easy to install and maintain. However, it can be more expensive than other vole management methods, and it may not be suitable for large gardens or farms.

Professional vole control services in Pennsylvania can also be hired to address vole problems. These services use a combination of techniques, including exclusionary methods, habitat modification, and chemical controls, to control vole populations and prevent damage to crops and gardens. Professional vole control services are especially useful for large gardens and farms, as they have the experience and equipment needed to effectively control vole populations. However, it is important to choose a reputable and experienced service provider to ensure the safety of the environment and the well-being of the voles.


Voles are an important part of Pennsylvania's ecosystem, and they play a crucial role in maintaining the balance of the food chain. However, their rapid reproduction and feeding habits can cause significant damage to crops and gardens. By using a combination of exclusionary methods, habitat modification, and vole control methods, Pennsylvania residents can protect their plants and preserve the health of the ecosystem. By understanding the importance of voles and the methods for managing their populations, residents can help to ensure a healthy and sustainable environment for generations to come.
