If you’ve ever watched squirrels scurry around your yard, you might wonder what they eat. Squirrels do not typically eat onions. Their diet mainly consists of nuts, seeds, fruits, and vegetables that are more appealing to them. Onions, with their strong flavor, are not a favorite among these furry creatures.
While you might think of offering some leftover onions to your backyard visitors, it’s good to know that these bulbs can be unpalatable and even toxic to many animals, including squirrels. Instead, focus on providing foods that they really enjoy, such as acorns and berries. This can help attract them to your yard in a safe and healthy way.
Understanding what squirrels eat can enhance your experience of observing them. You’ll feel good knowing that you’re supporting their natural diet and keeping them happy. So, keep those onions for your cooking and offer the squirrels something tastier instead!
Squirrel Dietary Habits

Squirrels are omnivores, which means they eat a variety of foods. Their diets include nuts, seeds, fruits, and more. Understanding what they eat helps you appreciate their role in the ecosystem and how they interact with our environment.
Natural Foods in a Squirrel’s Diet
Squirrels mainly eat:
- Nuts: Acorns, walnuts, and hazelnuts are favorites. Nuts provide important fats and proteins.
- Seeds: Sunflower seeds are often found in bird feeders and are a tasty choice for them.
- Fruits: They enjoy berries, apples, and bananas, which offer vitamins and hydration.
- Fungi: Mushrooms are also part of their diet, providing various nutrients.
While they sometimes eat insects or bird eggs, they generally avoid strong-flavored vegetables like onions and garlic. This preference helps them stay healthy. Squirrels use their keen sense of smell to find food and often collect and store it for later use, especially during winter months.
Squirrels and Human Food Interaction
Squirrels are known to be clever and resourceful when it comes to finding food. You may have seen them in your garden or visiting your bird feeders. They often approach people, hoping to find easy snacks.
While you might be tempted to feed them, it is best to stick to natural foods. Foods like chocolate and bread can be harmful. Instead, provide nuts, seeds, or corn if you want to attract them. Just remember, it’s important to avoid giving them processed foods.
Feeding squirrels can alter their natural habits, so enjoy watching them in their natural settings without interfering too much in their diet.
Onions and Squirrels

Squirrels are curious animals, but they typically avoid onions. Onions contain certain compounds that make them unappealing, and there are better food options for squirrels that you might want to consider if you’re trying to deter them.
The Effects of Onions on Squirrels
Most squirrels do not eat onions due to their strong taste and odor. Onions contain sulfur compounds that can be toxic to many animals. These compounds can lead to digestive issues in squirrels if consumed. The pungent smell is also likely to deter them.
Animals that eat onions, like some moles and deer, have different dietary needs compared to squirrels. While you might find other wildlife enjoying onions, squirrels prefer foods like pecans, peanuts, fruits, and vegetables. These options provide the energy and nutrition they need without the risks associated with eating onions.
Alternative Foods to Deter Squirrels
If you’re looking to deter squirrels from your garden, consider planting foods they dislike. Strong-smelling plants such as garlic can serve as natural repellents. The scent is uninviting to squirrels, which helps protect your garden.
Instead of onions, you might attract squirrels with safer foods. They love nuts, seeds, and fruit, so consider placing these items at a distance from your garden. In addition, creating barriers or using mulch can also help keep squirrels away. Remember, they’ll always choose a tasty treat if it’s available!
