Will Squirrels Eat Soybeans? A Deep Dive into Squirrel Diets and Agricultural Impact
Yes, squirrels will eat soybeans if they are readily available, especially during times when their preferred food sources are scarce. This can lead to significant agricultural damage, particularly during the early stages of soybean development.
Introduction: Understanding the Squirrel Diet
Squirrels are opportunistic omnivores, meaning their diet consists of a wide variety of foods depending on the season and availability. While they are known for their love of nuts, seeds, and fruits, they are also adaptable and will consume other sources of nutrition, including agricultural crops like soybeans. Understanding what attracts squirrels to soybeans and the impact they can have on soybean crops is crucial for farmers and gardeners alike. Determining whether squirrels will eat soybeans involves considering the overall ecosystem and squirrel behavior.
Soybeans as a Potential Food Source
Soybeans, a key agricultural commodity, are rich in protein and oil, making them a potentially attractive food source for squirrels. However, soybeans are not typically their first choice. Squirrels usually prefer foods higher in fat and carbohydrates, such as acorns, nuts, and berries. The question of whether squirrels will eat soybeans often comes down to availability and necessity.
- Nutritional Value: Soybeans provide a decent source of protein and carbohydrates.
- Availability: When preferred food sources are scarce, squirrels may turn to soybeans as a survival strategy.
- Stage of Growth: Squirrels are more likely to target soybeans in their early stages of development, when the plants are tender and vulnerable.
Factors Influencing Squirrel Predation on Soybeans
Several factors influence the likelihood of squirrels eating soybeans:
- Seasonality: Squirrels are more likely to consume soybeans during periods of food scarcity, such as late winter and early spring before their preferred food sources become available.
- Location: Squirrels residing near soybean fields or gardens are more likely to encounter and consume soybeans.
- Population Density: High squirrel populations can increase competition for food, driving them to consume a wider range of items, including soybeans.
- Alternative Food Sources: The availability of alternative food sources, like acorns and nuts, can influence whether squirrels will target soybeans. If these preferred foods are plentiful, soybeans are less likely to be consumed.
- Accessibility: Squirrels need to be able to access the soybeans. A dense field cover may deter some, while easy access will increase the likelihood of consumption.
The Impact of Squirrels on Soybean Crops
While squirrels may not be the primary pest of soybeans, their feeding habits can still cause damage, particularly in small-scale soybean gardens or near residential areas. The effects may include:
- Seedling Damage: Squirrels may dig up and eat newly planted soybean seeds, reducing plant density.
- Plant Damage: They may gnaw on young soybean plants, damaging stems and leaves, hindering growth.
- Yield Reduction: In severe cases, squirrel damage can reduce the overall yield of soybean crops.
It’s important to note that the overall impact of squirrels on commercial soybean production is generally considered minor compared to other pests like insects and deer. However, localized damage can be significant for individual farmers or gardeners.
Preventing Squirrel Damage to Soybean Crops
Several methods can be used to deter squirrels from feeding on soybeans:
- Fencing: Install physical barriers such as fences around soybean plots to prevent squirrels from accessing the plants.
- Repellents: Apply squirrel repellents, such as those containing capsaicin (the active ingredient in chili peppers), to soybean plants.
- Habitat Modification: Reduce squirrel habitat near soybean fields by removing brush piles and other potential nesting sites.
- Providing Alternative Food Sources: Plant trees that produce nuts and other foods squirrels prefer to divert their attention away from soybeans.
- Guard Animals: Cats or dogs can deter squirrels from entering soybean fields or gardens.
- Trapping: In severe cases, trapping and relocating squirrels may be necessary. However, this should be done humanely and in accordance with local regulations.
- Netting: Covering newly planted soybean seeds with netting can prevent squirrels from digging them up.

Frequently Asked Questions about Squirrels and Soybeans
What is the primary diet of squirrels?
Squirrels primarily consume nuts, seeds, fruits, fungi, and occasionally insects. Their diet is highly dependent on seasonal availability. While they will eat soybeans if other food sources are scarce, it is not their preferred food.
Are there any specific types of soybeans that squirrels prefer?
There’s no conclusive evidence suggesting squirrels prefer one type of soybean over another. Their interest is more likely driven by the availability of any soybeans and the lack of other food options. The tenderness of young plants may also play a role.
How can I tell if squirrels are the pests damaging my soybean crop?
Signs of squirrel damage include gnawed stems, dug-up seeds, and partially eaten soybean pods. Look for squirrel droppings and tracks near the damaged plants. Compare these signs to those of other common pests to accurately identify the culprit.
Will scarecrows deter squirrels from eating my soybeans?
Scarecrows may provide a temporary deterrent, but squirrels are intelligent animals and will quickly realize that the scarecrow poses no real threat. Combining scarecrows with other deterrent methods, such as repellents and fencing, is more effective.
Are there any natural predators of squirrels that can help control their population near soybean fields?
Yes, hawks, owls, foxes, and snakes are natural predators of squirrels. Encouraging these predators by providing suitable habitat can help control squirrel populations. However, it is important to maintain a balance to avoid introducing other ecological problems.
Can I use poison to control squirrels in my soybean field?
Using poison to control squirrels is generally not recommended and may be illegal in some areas. Poison can harm non-target species, including pets and beneficial wildlife. Safer and more humane methods of control, such as fencing and repellents, are preferable.
Do squirrels only eat soybeans during certain times of the day?
Squirrels are most active during the early morning and late afternoon. This is when they are most likely to forage for food, including soybeans. Protecting your soybean crops during these times is particularly important.
Will planting other crops around my soybean field help deter squirrels?
Planting certain deterrent plants, such as mint, garlic, and onions, around your soybean field may help deter squirrels. These plants have strong odors that squirrels find unpleasant. However, this may only offer limited protection.
How effective are ultrasonic pest repellers for deterring squirrels from eating soybeans?
The effectiveness of ultrasonic pest repellers is debatable. While some studies suggest they can deter rodents, others have found them to be ineffective against squirrels. Squirrels may quickly become accustomed to the ultrasonic sounds.
What are the legal regulations regarding squirrel control in my area?
Regulations regarding squirrel control vary by location. Check with your local wildlife agency or agricultural extension office to determine the specific regulations in your area. Some methods, such as trapping and relocation, may require permits.
Can I use bird feeders to distract squirrels from my soybean plants?
Providing bird feeders with sunflower seeds or other squirrel favorites might distract them from your soybean plants, but it can also attract more squirrels to the area overall. This strategy can be a trade-off, so carefully consider the potential benefits and drawbacks.
How can I ensure my soybean seeds germinate even if squirrels are present?
To ensure soybean seed germination despite the presence of squirrels:
- Use netting over freshly planted areas.
- Consider planting slightly more seeds than needed to compensate for potential losses.
- Apply repellents directly to the seeds before planting.
- Maintain a vigilant watch, especially during peak squirrel activity times.
By understanding squirrel behavior and implementing appropriate control measures, you can minimize the impact of squirrels on your soybean crops and protect your investment. The question of whether squirrels will eat soybeans is less important than knowing how to manage their potential impact.
