Squirrels are small, furry rodents that are a familiar sight in many parts of the world. With their bushy tails, quick movements, and acrobatic abilities, they are often a source of fascination and amusement. However, squirrels can also cause problems, particularly when they damage property or steal food. In this article, we will explore the biology of squirrels, their habitat and behavior, indicators of their presence, and how to prevent squirrel problems.

Biology of Squirrels

Squirrels are members of the rodent family and are found throughout the world, except for Australia and Antarctica. There are more than 200 species of squirrels, ranging in size from the tiny African pygmy squirrel to the large Indian giant squirrel. Squirrels are herbivores and their diet includes nuts, seeds, fruits, and sometimes insects and small animals.

Squirrels have four front teeth that never stop growing, which allows them to gnaw on hard objects such as nuts and wood. They also have sharp claws and excellent eyesight, which enables them to navigate through trees and detect potential predators.

Habitat and Behavior of Squirrels

Squirrels can be found in a variety of habitats, including forests, parks, and suburban areas. They are most commonly seen in trees, where they build nests called dreys. Dreys are made of twigs, leaves, and other materials and are typically located high up in trees. Squirrels are active during the day and spend much of their time searching for food and building or repairing dreys.

Squirrels are social animals and may live in groups, particularly in the winter when they huddle together for warmth. They communicate with each other using a variety of vocalizations and body language, including tail flicks and ear movements.

Indicators of Squirrel Presence

The most obvious indicator of squirrel presence is the sight of them climbing trees or running along power lines. Other indicators of squirrel activity include damage to gardens or crops, as squirrels may eat fruits and vegetables. Squirrels may also take up residence in attics, garages, or other structures, and you may hear scratching or rustling noises coming from these areas.

Preventing Squirrel Problems

To prevent squirrel problems, it’s important to eliminate sources of food and shelter that may attract them to your property. This includes securing garbage cans and compost bins, keeping pet food indoors, and sealing up any holes or gaps in your home’s exterior. Squirrels are also attracted to bird seed, so it’s important to use squirrel-proof bird feeders or feeders that are placed far away from trees or other objects that squirrels can climb.

If you have squirrels living on your property, it’s important to avoid contact with them. Squirrels can carry diseases such as rabies, so it’s best to keep your distance. Instead, contact a professional wildlife removal company to remove the squirrels from your property safely.


Squirrels are fascinating creatures that provide valuable benefits to the environment. While they can be considered pests, they can also help to disperse seeds and control insect populations. By understanding the biology and behavior of squirrels and taking steps to prevent problems, you can coexist with these creatures in a safe and respectful manner.
