1. What Do Squirrels Eat?
Squirrels are opportunistic omnivores, meaning they consume both plant and animal matter. Their diet is quite diverse and adapts to what’s available in their environment, changing with the seasons. Understanding their diet is the first step in managing their presence around your property. According to a study by the University of California, Davis, squirrels’ diets are heavily influenced by the availability of nuts and seeds, but they also consume fruits, fungi, and even insects when necessary.
2. Common Squirrel Food Sources
Squirrels have a wide range of food sources, including:
- Nuts: Acorns, hazelnuts, pecans, walnuts, and hickory nuts are staples in their diet, especially during fall and winter.
- Seeds: Sunflower seeds, pumpkin seeds, and various other seeds found in bird feeders or gardens are a favorite.
- Fruits: Apples, berries, grapes, and other fruits from trees and bushes provide essential nutrients.
- Vegetables: Squirrels enjoy vegetables like corn, squash, and carrots, often found in gardens.
- Fungi: Mushrooms and other fungi are a part of their natural diet, especially in wooded areas.
- Insects and Eggs: While less common, squirrels will eat insects, caterpillars, and even bird eggs, providing them with protein.
- Tree Bark and Buds: In the early spring, when other food sources are scarce, squirrels will feed on tree bark and buds.
| Food Group | Examples | Nutritional Benefits | Season |
|---|---|---|---|
| Nuts | Acorns, Hazelnuts, Pecans, Walnuts | High in fats, proteins, and essential nutrients | Fall/Winter |
| Seeds | Sunflower Seeds, Pumpkin Seeds, Bird Seeds | Rich in oils, vitamins, and minerals | Year-Round |
| Fruits | Apples, Berries, Grapes, Melons | Source of vitamins, sugars, and hydration | Summer/Fall |
| Vegetables | Corn, Squash, Carrots, Broccoli | Provides vitamins, minerals, and fiber | Summer/Fall |
| Fungi | Mushrooms, Truffles | Source of vitamins and minerals | Spring/Fall |
| Insects | Caterpillars, Grubs, Beetles | Excellent source of protein | Spring/Summer |
| Eggs | Bird Eggs | High in protein and fats | Spring |
| Tree Bark & Buds | Maple Bark, Beech Buds | Provides essential nutrients during lean times | Early Spring |
3. Where Do Squirrels Look for Food?
Squirrels are resourceful foragers and will seek food in a variety of locations:
- Hardwood Forests: These forests are rich in nuts, acorns, and seeds, making them a prime feeding ground.
- Orchards: Fruit and nut orchards offer a bounty of easily accessible food.
- Gardens: Gardens provide vegetables, fruits, and seeds, making them attractive to squirrels.
- Bird Feeders: Squirrels are notorious for raiding bird feeders, consuming sunflower seeds and other birdseed mixes.
- Parks and Campuses: Public parks and university campuses often have food scraps and accessible garbage cans, making them scavenging hotspots.
- Residential Areas: Squirrels will readily forage in residential areas, taking advantage of gardens, fruit trees, and accessible food sources.
According to the National Wildlife Federation, squirrels play an essential role in seed dispersal. They bury nuts and seeds and often forget where they are, which helps trees and plants spread.
4. Dangers of Feeding Squirrels Human Food
While it may be tempting to feed squirrels, providing them with human food can be detrimental to their health. Human foods often contain high levels of sugar, salt, and unhealthy fats, leading to various health issues.
- Weight Gain: Processed foods and sugary snacks can cause squirrels to gain excessive weight, affecting their mobility and overall health.
- Dental Problems: Sugary foods can lead to tooth decay and other dental issues.
- Metabolic Bone Disease: An imbalanced diet lacking essential nutrients can result in metabolic bone disease, weakening their bones.
- Dependence on Humans: Feeding squirrels can make them dependent on humans for food, reducing their natural foraging abilities.
- Overpopulation: Providing a consistent food source can lead to overpopulation in an area, causing increased competition for resources and potential conflicts.
Instead of feeding squirrels directly, consider providing them with natural food sources in your yard, such as native trees and plants that produce nuts, seeds, and fruits.
5. Should You Feed Squirrels in Your Backyard?
It’s generally not advisable to intentionally feed squirrels in your backyard. While it may seem harmless, feeding squirrels can lead to several problems.
- Increased Dependence: Squirrels may become dependent on human-provided food, reducing their ability to forage naturally.
- Nuisance Behavior: They may become bolder and more persistent in seeking food, leading to nuisance behavior around your home.
- Attracting Other Pests: Food left out for squirrels can attract other unwanted pests, such as rats and mice.
- Overpopulation: A consistent food source can contribute to overpopulation, leading to increased competition and stress among the squirrel population.
If you want to support squirrels in your backyard, consider planting native trees and shrubs that provide natural food sources and habitat. According to the Arbor Day Foundation, native plants are best suited for local wildlife and require less maintenance.
6. Where Do Squirrels Eat?
Squirrels are known for their hoarding behavior, storing food for later consumption. They typically eat in the following ways:
- On the Spot: They may eat food immediately after finding it, especially if they are hungry.
- Hidden Locations: Squirrels often carry food to a safe spot, such as a tree branch or a secluded area, before eating it.
- Hoarding Locations: They store food in caches, either scattered or in a central location, and retrieve it later for consumption.
Squirrels have two primary methods of hoarding: scatter hoarding and larder hoarding. Understanding these behaviors can help you understand how they manage their food resources.
7. Scatter Hoarding vs. Larder Hoarding
Squirrels employ two main strategies for hoarding food:
- Scatter Hoarding: This involves burying individual nuts or seeds in multiple locations. The squirrel relies on its memory and spatial awareness to retrieve the hidden food. This method is common among gray squirrels.
- Larder Hoarding: This involves storing all food in one or a few central locations, such as a tree cavity or an attic. The squirrel defends these locations to protect its cache. This method is more common among red squirrels.
| Hoarding Method | Description | Advantages | Disadvantages |
|---|---|---|---|
| Scatter Hoarding | Burying individual food items in multiple locations | Reduces risk of losing entire food supply to a single predator or competitor | Requires excellent memory and spatial awareness to relocate caches |
| Larder Hoarding | Storing all food in one or a few central locations | Easier to defend and monitor food supply | Risk of losing entire food supply to a single predator, competitor, or environmental event |
8. Signs of a Squirrel Infestation
If squirrels have taken up residence in your home, you may notice the following signs:
- Unusual Noises: Scampering, scratching, or gnawing sounds in the attic or walls.
- Droppings: Squirrel droppings in and around your home.
- Scratch Marks: Scratches or claw marks around entry points.
- Nests: Finding nests made of leaves, twigs, and other materials in your attic or chimney.
- Food Caches: Piles of nuts or acorns in your attic, roof, or yard.
- Damage to Property: Chewed wires, damaged insulation, or holes in the roof.
According to the Humane Society, squirrels can cause significant damage to homes if left unchecked. Their constant gnawing can compromise the structural integrity of your property.
9. How to Prevent a Squirrel Infestation
Preventing a squirrel infestation involves taking steps to eliminate food sources and secure potential entry points.
- Remove Food Sources: Clean up fallen nuts, seeds, and fruits in your yard.
- Secure Bird Feeders: Use squirrel-proof bird feeders or place them in locations that are difficult for squirrels to access.
- Cover Garbage Cans: Use tightly sealed garbage cans to prevent squirrels from accessing food waste.
- Protect Gardens: Use netting or fencing to protect fruit and vegetable gardens.
- Seal Entry Points: Inspect your home for potential entry points and seal them with caulk, steel wool, or metal flashing.
- Trim Trees: Trim tree branches that overhang your roof to prevent squirrels from jumping onto your home.
- Use Repellents: Consider using squirrel repellents, such as those containing capsaicin, to deter them from your property.
By taking these preventive measures, you can reduce the likelihood of a squirrel infestation and protect your home from damage.
