Can Chipmunks Help Keep Mice Away?

While chipmunks may exhibit territorial behavior and occasionally chase away small rodents like mice, they do not provide an effective long-term solution to keep mice away. Chipmunks primarily focus on gathering food and storing it, rather than actively hunting and eliminating mice populations. Additionally, chipmunks may themselves cause damage by digging burrows in gardens and lawns. To effectively control mice, it is recommended to implement proper sanitation practices, seal off potential entry points, and use traps or professional pest control measures.

Chipmunks: Facts and Characteristics

Description of Chipmunks

Chipmunks are small, ground-dwelling rodents that are part of the squirrel family. They are typically 5-6 inches long and weigh about 2-3 ounces. They have a striped fur coat with white and brown or gray colors. Chipmunks can be found in wooded areas and fields, but they are also known to inhabit suburban neighborhoods and urban parks.

Diet and Eating Habits

Chipmunks are omnivores, which means they eat both plant and animal material. They primarily feed on nuts, seeds, berries, and insects. Chipmunks have cheek pouches that they use to carry food back to their burrows. They are also known to store food in their burrows for the winter.

Social Behavior and Territoriality

Chipmunks are solitary animals, but they are not entirely territorial. They have home ranges, but these ranges can overlap with other chipmunks. They mark their territory with scent glands located on their cheeks and feet. They also communicate with each other through vocalizations and body language.

Mice: Facts and Characteristics

Description of Mice

Mice are also small rodents that are typically 2-3 inches long and weigh about half an ounce. They have a pointed snout and large ears. Mice can be found in a variety of habitats, including fields, forests, and urban areas.

Diet and Eating Habits

Mice are omnivores and feed on a variety of food sources, including seeds, fruits, and insects. They are also known to consume human food and can cause significant damage to crops and homes.

Social Behavior and Territoriality

Mice are social animals and live in groups called colonies. They establish territories and communicate with each other through vocalizations, scent marking, and body language.

The Interaction Between Chipmunks and Mice

Shared Habitats and Resources

Chipmunks and mice have overlapping habitats and share many of the same resources. They both feed on seeds, nuts, and insects, and they both nest in burrows in the ground.

Competition for Food and Shelter

While they share resources, chipmunks and mice can also compete with each other for food and shelter. In areas where resources are limited, they may become aggressive toward each other.

Instances of Aggression and Territorial Disputes

In some instances, chipmunks and mice may become aggressive toward each other and engage in territorial disputes. This can lead to injury or even death of one or both animals.

Do Chipmunks Keep Mice Away?

Scientific Studies and Expert Opinions

There is some evidence to suggest that chipmunks can help deter mice from an area. Chipmunks are known to be territorial animals, and their presence may discourage mice from entering their territory. However, the extent to which chipmunks can control mouse populations is still unclear.

Factors Influencing the Relationship between Chipmunks and Mice

Several factors can influence the relationship between chipmunks and mice, including

  1. Availability of Food and Shelter: The presence of abundant food and shelter may reduce competition between chipmunks and mice, leading to less aggressive behavior.
  2. Population Densities: High population densities of both chipmunks and mice can lead to increased competition for resources and more aggressive behavior.
  3. Predators and Threats: The presence of predators such as cats or owls can lead to a reduction in both chipmunk and mouse populations, which may impact their interaction with each other.

Potential Deterrents of Mice Due to Chipmunks

There are a few potential ways that chipmunks may deter mice from an area:

  1. Territorial Behavior: As mentioned before, chipmunks are territorial animals and may defend their territory against mice. The scent marking that chipmunks use to mark their territory may also repel mice.
  2. Indirect Effects on Mice Populations: If chipmunks are able to successfully compete with mice for resources, this may indirectly reduce the number of mice in an area.

Pros and Cons of Chipmunks as a Mice Deterrent


  1. Natural Pest Control: Chipmunks can provide natural pest control by deterring mice from an area. This can help reduce the need for chemical or inhumane methods of pest control.
  2. Lower Reliance on Chemical or Inhumane Methods: Using chipmunks as a natural pest control method can help reduce the need for chemical pesticides or inhumane trapping methods.


  1. Damage to Gardens and Property: Chipmunks can cause damage to gardens and homes by digging burrows and eating plants.
  2. Inconsistency in Effectiveness: The effectiveness of chipmunks as a mouse deterrent is inconsistent and may not work in all situations.
  3. Possibility of Attracting Other Pests: While chipmunks may deter mice, their presence may attract other pests such as squirrels or rats.

Alternative Methods of Mice Control

There are several alternative methods of mice control that homeowners and gardeners can use, including:

  1. Traps and Deterrents: Live traps or ultrasonic deterrents can be used to capture or repel mice from an area.
  2. Biological Controls: Using natural predators such as cats or owls to control mouse populations can be effective.
  3. Preventative Measures to Reduce Food Sources and Entry Points: Removing food sources such as spilled birdseed or pet food and sealing entry points can help prevent mice from entering homes or gardens.


Q. Do Chipmunk Eat Mice?

No, chipmunks do not eat mice. Chipmunks are omnivorous animals that primarily feed on nuts, seeds, berries, fruits, and insects. They are not natural predators of mice and do not typically hunt or consume them as a food source.

Q. Will Chipmunk Eat Mice Bait?

As for using mice bait to attract chipmunks, it is not recommended. Chipmunks have different dietary preferences and are more likely to be attracted to seeds, nuts, fruits, and insects. Using mice bait could potentially harm chipmunks or create an imbalance in their natural diet.

Q. Should You Let Chipmunk Loose In The House?

Letting chipmunks loose in the house is not advisable. Chipmunks are wild animals and their natural habitat is outdoors. Bringing them inside can result in damage to your property, as they are known for digging and chewing. Additionally, they may carry diseases or parasites that could be harmful to humans and other pets.

Q. Do Chipmunks Makes Good Pet?

While some people may find chipmunks adorable and fascinating, they generally do not make good pets. Chipmunks have specific needs and behaviors that are difficult to replicate in a home environment. They require ample space, access to the outdoors, and a diet that closely resembles their natural food sources. In many places, it is also illegal to keep chipmunks as pets without proper permits. It is best to appreciate and observe chipmunks in their natural habitat rather than attempting to keep them as pets.

Q. Should You Keep Chipmunks In A Garden?

Keeping chipmunks in a garden can have both positive and negative consequences. On the positive side, chipmunks can contribute to the ecosystem by dispersing seeds and acting as a form of pest control by eating insects and other small creatures. They can also be entertaining to watch and can add a natural and lively element to a garden.

However, there are potential drawbacks to keeping chipmunks in a garden. Chipmunks are known for their burrowing behavior, which can lead to damage to lawns, plants, and garden structures. They may also feed on bulbs, seeds, and fruits, potentially causing damage to crops and flowers. Additionally, chipmunks can attract other wildlife, such as snakes or larger predators, which could pose a threat to a garden or its surroundings.


Understanding the relationship between chipmunks and mice is important for homeowners and gardeners. While chipmunks may have some effectiveness in deterring mice, their presence can also cause damage to gardens and homes. Homeowners and gardeners should consider alternative methods of mice control and take preventative measures to reduce food sources and entry points. Further research and observation are needed to fully understand the relationship between chipmunks and mice and their impact on pest control.
