Squirrels are a common sight in many parts of the world, including North America, Europe, and Asia. They are known for their acrobatic abilities, cute appearance, and bushy tails. However, despite their popularity, squirrels face many challenges in the wild, including predators, diseases, and environmental hazards. In this article, we will explore the question: what kills most squirrels?


One of the biggest threats to squirrels in the wild is predators. Squirrels are preyed upon by a wide range of animals, including hawks, owls, eagles, snakes, foxes, coyotes, and even domestic cats and dogs. These predators rely on their sharp senses and hunting skills to catch squirrels, which are fast and agile climbers.

One of the ways squirrels avoid predators is by staying high up in trees, where they are less likely to be caught. They also have the ability to jump long distances, which helps them escape danger. However, even with these defenses, many squirrels still fall victim to predators.


Another factor that kills many squirrels is diseases. Squirrels are susceptible to a range of illnesses, including rabies, mange, and squirrelpox. These diseases can weaken squirrels, making them more vulnerable to predators and other dangers.

Rabies is a viral disease that affects the nervous system of mammals, including squirrels. It is transmitted through the saliva of infected animals and can be fatal if left untreated. Mange is a skin disease caused by mites that can cause hair loss and skin irritation. Squirrelpox is a viral disease that can cause lesions on the skin and eyes and can be fatal in some cases.

Environmental Hazards

Squirrels also face many environmental hazards that can kill them. These hazards include extreme temperatures, harsh weather conditions, and habitat loss. In areas where winters are cold, squirrels may struggle to find enough food to survive, which can lead to starvation. In areas where summers are hot, squirrels may suffer from heatstroke or dehydration.

Habitat loss is another major threat to squirrels. As humans continue to expand their cities and towns, they often destroy or alter squirrel habitats, making it harder for squirrels to find food and shelter. This can lead to a decline in squirrel populations and put them at risk of extinction in some areas.

How to Protect Squirrels

If you want to help protect squirrels, there are several things you can do. One of the simplest ways is to provide food and water for squirrels in your backyard. You can put out bird feeders and water dishes, or even build a squirrel feeder. Just be sure to use squirrel-proof feeders and keep the area clean to prevent the spread of disease.

Another way to help squirrels is to plant trees and shrubs that provide food and shelter for them. Squirrels rely on trees for their survival, so planting more trees in your community can help support local squirrel populations. You can also support conservation efforts by donating to organizations that work to protect squirrels and their habitats.


In conclusion, squirrels face many challenges in the wild, including predators, diseases, and environmental hazards. While it is difficult to determine which of these factors kills the most squirrels, it is clear that they all play a role in their survival. By taking steps to protect squirrels and their habitats, we can help ensure that these cute and acrobatic animals continue to thrive in the wild for generations to come.
