Protecting wildlife and promoting their well-being is crucial for maintaining a balanced ecosystem.

While squirrels can be adorable and entertaining to watch, it’s important to know which foods can be harmful to them.

If you’re wondering what foods can harm squirrels, you’ve come to the right place.

In this article, we will discuss the foods you should avoid feeding squirrels to ensure their health and safety.

Understanding Squirrel Diet

Squirrels are fascinating creatures that belong to the rodent family. They have a varied diet that consists of both plant-based and protein-rich foods. Understanding their natural diet and nutritional needs is crucial to ensuring their health and well-being.

Natural Diet of Squirrels

Squirrels in the wild primarily feed on a diet that includes nuts, seeds, fruits, vegetables, and fungi. Tree nuts such as acorns, walnuts, and hazelnuts are a staple food source for squirrels. They also enjoy eating seeds like sunflower seeds, pumpkin seeds, and pine cones. Fruits like berries, apples, and pears are also commonly consumed by squirrels. Additionally, squirrels may forage for vegetables like corn, carrots, and leafy greens.

It’s important to note that squirrels are opportunistic eaters, meaning they will adapt their diet based on what is available in their environment. For example, if there is a scarcity of nuts, they may rely more on fruits and vegetables for sustenance.

Nutritional Needs of Squirrels

Squirrels have specific nutritional needs that must be met in order for them to thrive. They require a balance of carbohydrates, protein, and fats in their diet. Carbohydrates provide energy, while protein is essential for growth and repair. Fats are a concentrated source of energy and are important for maintaining body temperature.

In addition to macronutrients, squirrels also require a variety of vitamins and minerals. These include vitamin E, vitamin B complex, calcium, phosphorus, and iron. These nutrients are crucial for their overall health and proper functioning of their bodily systems.

If you are caring for a pet squirrel or have squirrels visiting your backyard, it’s important to provide them with a diet that mimics their natural food sources. This can include a combination of nuts, seeds, fruits, and vegetables. However, it’s crucial to avoid certain foods that can be harmful to squirrels.


Foods to Avoid Feeding Squirrels

Squirrels are adorable creatures that often visit our backyards and parks, captivating us with their acrobatic antics. While it may be tempting to share our food with them, it’s important to know that not all human foods are safe for squirrels. In fact, some foods can be harmful and even toxic to them. To ensure the health and well-being of these furry friends, here are some foods you should avoid feeding squirrels:

Processed Foods and Junk Food

Just like humans, squirrels thrive on a natural diet that includes nuts, seeds, fruits, and vegetables. Processed foods and junk food, on the other hand, are not suitable for their digestive system. These foods are often high in unhealthy fats, sugars, and additives that can lead to weight gain, diabetes, and other health issues in squirrels. So, it’s best to keep those potato chips and cookies to yourself and stick to their natural diet.

Highly Salty Foods

Squirrels have a low tolerance for salt. Foods that are high in salt, such as salted nuts, pretzels, or salty snacks, can disrupt their delicate electrolyte balance and lead to dehydration. Excessive salt intake can also cause kidney problems in squirrels. So, when offering them treats, make sure to avoid anything that is heavily salted.

Sweet Treats and Sugary Foods

Squirrels have a sweet tooth just like us, but that doesn’t mean they should indulge in sugary treats. Foods like chocolates, candies, and other sugary snacks can be harmful to squirrels. Their small bodies are not designed to process large amounts of sugar, and it can cause digestive issues, tooth decay, and obesity in these little critters. Stick to their natural diet and avoid the temptation to share your sweets.

Toxic Foods for Squirrels

While some human foods are simply not suitable for squirrels, others can be outright toxic to them. For example, avocados, grapes, raisins, onions, and garlic can be toxic to squirrels and should be kept away from them. These foods contain substances that can cause severe illness and even be fatal to squirrels. If you suspect that a squirrel has ingested any toxic food, it’s important to seek veterinary assistance immediately.

Remember, the best way to show your love for squirrels is by providing them with a safe and healthy environment. Stick to their natural diet of nuts, seeds, fruits, and vegetables, and avoid feeding them processed, salty, sweet, or toxic foods. By doing so, you’ll contribute to their well-being and ensure that they continue to bring joy to your backyard for years to come.

Health Risks for Squirrels

When it comes to feeding squirrels, it is important to be aware of the potential health risks associated with certain foods. While you may have good intentions, feeding them the wrong types of food can lead to various health problems. Here are some of the health risks you should be aware of:

Digestive Problems

Squirrels have a delicate digestive system that is specifically designed to process certain types of food. Feeding them foods that are high in fat or sugar, such as chocolate or processed snacks, can cause digestive problems like diarrhea or constipation. Additionally, foods that are difficult to digest, like bread or nuts, can lead to bloating and discomfort for these furry creatures. It is best to stick to their natural diet, which mainly consists of nuts, seeds, fruits, and vegetables.

Obesity and Malnutrition

Just like humans, squirrels can also suffer from obesity and malnutrition. Feeding them a diet that is high in calorie-rich foods, such as junk food or fatty treats, can lead to weight gain and obesity. On the other hand, providing them with a diet that lacks essential nutrients can result in malnutrition. It is important to strike a balance and provide them with a well-rounded diet that meets their nutritional needs. This includes a variety of nuts, seeds, fruits, and vegetables to ensure they get the necessary vitamins and minerals.

Toxicity and Poisoning

Some foods that we commonly consume can be toxic to squirrels. For example, certain types of plants like azaleas or rhododendrons can be highly toxic to these small animals. Additionally, foods that are safe for humans but contain toxic substances for squirrels, such as onions or garlic, should be avoided. It is crucial to research and educate yourself on the potential toxicity of certain foods before offering them to squirrels. If you suspect that a squirrel has ingested something toxic, it is important to seek veterinary assistance immediately.

Safe Alternatives for Squirrels

While it’s important to know which foods are harmful to squirrels, it’s equally important to provide them with safe alternatives. Here are some options that you can offer to squirrels in your area:

Nuts and Seeds

Squirrels love nuts and seeds, and they can be a great source of nutrition for them. Instead of feeding them peanuts, which can be harmful if contaminated with aflatoxins, offer them unsalted and shelled nuts like almonds, walnuts, or hazelnuts. Other safe options include sunflower seeds, pumpkin seeds, and pine nuts. Just make sure to provide them in moderation as a treat, as too much fat can be unhealthy for squirrels.

Fresh Fruits and Vegetables

Adding fresh fruits and vegetables to a squirrel’s diet can provide them with essential vitamins and minerals. Offer them small pieces of fruits like apples, berries, and bananas. Leafy greens such as spinach and kale can also be given to squirrels. Remember to wash the fruits and vegetables thoroughly and remove any seeds or pits that could be harmful to the squirrels.

Natural Food Sources

Squirrels are natural foragers and are equipped to find food in their environment. You can encourage their natural behavior by providing them with access to natural food sources. Planting trees and shrubs that produce nuts, berries, or acorns can create a natural habitat for squirrels, allowing them to find food on their own. Additionally, leaving fallen fruits or nuts on the ground can provide squirrels with a natural food source.

It’s important to remember that while these foods are generally safe for squirrels, it’s always best to consult with a wildlife expert or veterinarian if you have any concerns about their diet. By providing them with safe alternatives, you can help ensure the health and well-being of the squirrels in your area.

Promoting Squirrel-Friendly Environment

Squirrels are adorable creatures that bring joy to many people. If you want to create a squirrel-friendly environment in your backyard or garden, there are a few key steps you can take.

Providing Clean Water

One of the most important things you can do to promote a squirrel-friendly environment is to provide clean water for them to drink. Squirrels need access to fresh water just like any other animal. You can place a shallow dish or a bird bath in your yard and keep it filled with clean water. This will not only keep the squirrels hydrated but also attract other wildlife to your backyard.

Creating Natural Feeding Areas

Squirrels are opportunistic eaters and will feed on a variety of foods. However, it’s important to create natural feeding areas for them to ensure they’re getting the right nutrients. Planting trees, shrubs, and flowers that produce nuts, seeds, and berries will provide a natural food source for squirrels. You can also hang bird feeders or squirrel feeders in your yard with a mix of nuts and seeds that squirrels love.

Avoiding Chemical Use

Chemicals such as pesticides, herbicides, and fertilizers can be harmful to squirrels and other wildlife. If you want to create a squirrel-friendly environment, it’s best to avoid using these chemicals in your yard. Instead, opt for organic and natural alternatives to maintain your garden. This not only benefits the squirrels but also helps protect the overall ecosystem of your backyard.

By following these steps and promoting a squirrel-friendly environment, you can ensure that these delightful creatures have a safe and healthy place to thrive. Remember, creating a harmonious coexistence with nature is not only beneficial for wildlife but also for our own wellbeing.


In conclusion, understanding the proper diet for squirrels and avoiding harmful foods is essential for their well-being.

Feeding them inappropriate foods can lead to various health risks and even endanger their lives.

By sticking to their natural diet and providing safe alternatives, you can contribute to the overall health and happiness of squirrels.

Remember to create a squirrel-friendly environment where they can thrive without unnecessary risks.

Let’s cherish these wonderful creatures and ensure their safety for generations to come.
