Understanding Bark Stripping by Squirrels

Bark stripping by squirrels is a natural behavior that can cause significant damage to trees in your garden or local parks. It’s the process where squirrels remove strips of bark from branches, twigs, and even the trunk of trees for various reasons, such as gaining access to the sugary sap beneath, creating nesting materials, or simply as part of their gnawing behavior to wear down their ever-growing teeth.

Identifying Trees at Risk

Various species are more susceptible to damage from squirrels. These typically include soft-barked trees such as maples and young fruit trees. Recognizing signs of bark stripping early is key to mitigating harm. It usually appears as long, narrow strips of removed bark, and in some cases, you may see fresh wounds with sap running down the trunk.

Why Squirrels Strip Bark

Squirrels strip bark for reasons ranging from dietary needs to nest building. During certain seasons when food is scarce, the inner bark provides vital nutrients. Additionally, female squirrels often strip bark to build comfortable nests for their offspring.

Protecting Your Trees Naturally

Before resorting to products, modifying your landscape can discourage squirrels. Planting squirrel-deterring flowers or herbs around at-risk trees could help repel these rodents. Additionally, maintaining tree health can make them less attractive targets.

Physical Barrier Solutions

Applying physical barriers to trees is an effective way to prevent bark stripping. Products like tree guards are widely available and can offer a protective shield. An example is the ‘Tree Pro Bark Protector’, which wraps around the trunk and keeps squirrels at bay.


  • Easy to install and remove
  • Environmentally friendly

Commercial Repellents

The market offers various commercial repellents designed to deter squirrels from stripping bark. For instance, ‘I Must Garden Squirrel Repellent’ is designed to be sprayed directly onto the bark, creating an unpleasant taste for squirrels.


  • Easy to apply
  • Made with natural ingredients
  • Long-lasting formula


  • May require reapplication after rain
  • Some repellents have a strong odor
  • Not foolproof for every squirrel species

Environmental Enrichments

Creating an engaging habitat can distract squirrels from damaging trees. Introducing alternative food sources or squirrel feeders away from at-risk trees can shift their attention and provide them with nutrients needed during scarce periods.

Homemade Remedies and Deterrents

Many gardeners resort to homemade detergents like pepper sprays or hanging Irish Spring soap near trees. While these may provide a temporary fix, their effectiveness varies and requires frequent application.

Pruning and Tree Care

Pruning can sometimes mitigate bark stripping by removing lower branches that provide easy access. Keeping your trees well-watered and healthy can also discourage squirrels, as they prefer the bark of stressed trees.

Understanding Squirrel Behavior

Learning about local squirrel behavior and their life cycles can help you anticipate and prevent bark stripping. For instance, states that squirrels tend to nest twice a year and can become more aggressive about collecting nesting materials during these periods.

Utilizing Technology for Deterrence

There are motion-activated devices like ‘Orbit 62100 Yard Enforcer’ that can startle and fend off squirrels using water sprays. These devices can be set up near the trees to provide an automated deterrent solution.


  • Conserves water with motion activation
  • Can be used day and night
  • Adjustable settings for sensitivity


  • Requires a nearby water source and hose
  • Might not deter all squirrels
  • Can accidentally activate with other movement

Seeking Professional Advice

If your efforts to deter squirrels haven’t been fruitful, seeking professional advice might be your next step. Certified arborists or wildlife control experts can offer tailored solutions based on an in-depth assessment of your specific situation and the local squirrel population.

Community Engagement and Education

Engaging with your community can also be beneficial. Educating neighbors about the importance of tree protection and squirrel management can lead to a collective approach that is more effective than individual efforts.

Innovative Products That Offer Protection

In addition to traditional tree guards, there are innovative products like plastic spirals or mesh that wrap around the tree. One such product is the ‘Leonard Plastic Mesh Tree Guard’. It provides a barrier that prevents squirrels from reaching the bark while allowing the tree to breathe and grow.


  • Allows for air and light penetration
  • Flexible material accommodates tree growth
  • Durable against various weather conditions


  • May be unsightly on ornamental trees
  • Requires monitoring to avoid trapping moisture
  • Installation can be more time-consuming than simpler guards

Investing in Squirrel-Proofing Your Landscape

Investing in a squirrel-proof landscape might involve the strategic placement of bird feeders, using squirrel-proof designs, or the addition of decoy food sources as you might have already discovered in pollinator-friendly vegetable gardens.

Companion Planting for Natural Repellence

Companion planting could also serve as a natural deterrent. Some gardeners swear by the repellent qualities of plants like daffodils, hyacinths, and the allium family, to keep squirrels at bay from their prized trees and garden spaces.

Ensuring the Health of Infected Trees

If your tree already has some damage, it’s important to ensure that the health of the tree is maintained. Regular inspection and care for wounds can prevent disease and promote healing. Arborists can also treat trees with specific products that encourage bark regeneration.

Regular Inspection and Maintenance

Regular inspection of your trees for signs of squirrel activity is imperative. Early detection can go a long way in preventing extensive damage, and keeping up with regular maintenance routines can keep your trees in optimal health.

Install Feeders to Distract Squirrels

Install squirrel feeders that provide a steady source of food like nuts and seeds to keep them satiated and distracted from your trees. Feeding squirrels might seem counterintuitive, but with careful placement away from at-risk trees, it can help mitigate bark-stripping.

Impact of Other Wildlife on Tree Protection

Understanding the role of other wildlife in your local ecosystem can also be instrumental. Encouraging the presence of natural squirrel predators, such as birds of prey, could indirectly protect your trees by controlling the squirrel population.

Long-Term Tree Health Strategies

Investing in long-term tree health strategies, including deep-watering practices, proper fertilization, and soil care, establishes stronger trees that are less likely to be targeted by squirrels and can recover better from any damage incurred.

Assessing Seasonal Variations

It’s important to assess the seasonal variations in squirrel behavior. For instance, food hoarding is most intense in the fall, leading to increased bark stripping. Planning deterrent methods around these peak times can yield better results.

Exploring Organic and Eco-Friendly Options

For those who prefer environmentally-friendly methods, exploring organic and eco-friendly options should be a priority. Biodegradable tapes and natural bitters may serve as deterrents without harming the squirrels or the environment.

Understanding the Legalities

Finally, be sure to understand the legalities surrounding wildlife control in your area. Some methods for deterring or controlling squirrels may be restricted or require special permits. It’s always best to be informed and compliant with local wildlife regulations.

Assessing the Effectiveness of Deterrents Over Time

When implementing solutions to protect your trees from bark-stripping squirrels, monitoring their effectiveness over time is crucial. Regular checks will help determine if adjustments or alternative strategies are needed.

Periodically evaluating the measures you have put in place may reveal the need for additional protection or modifications to existing deterrents. Some products might degrade with weather exposure, while squirrels could grow accustomed to certain repellents, necessitating a change in approach.

Collaboration with Local Experts and Resources

Partnering with local experts and utilizing community resources can offer significant advantages. For example, you might participate in a local gardening club or attend workshops on tree care and wildlife management.

Local university extension services can also be a wealth of knowledge, providing insight into the latest research on squirrel behavior and tree protection. Their guidance can be invaluable in both preventing and addressing bark stripping on your property.

Pros and Cons of Using Wildlife Rescue Centers

Contacting wildlife rescue centers can offer a humane approach to managing pesky squirrels. These centers sometimes provide relocation services or additional advice on cohabiting with local wildlife.


  • Humane management of squirrel populations
  • Expert knowledge on local wildlife behaviors
  • Services often provided at low or no cost


  • Relocation might not be a long-term solution
  • Availability of services can be limited
  • May not address the root cause of bark stripping

Exploring the Role of Landscaping in Squirrel Management

The way you landscape your garden or property can greatly impact squirrel behavior. Strategic planting and the arrangement of trees, shrubs, and other vegetation can either invite or deter wildlife.

For example, including plants that produce nuts and berries away from the areas where protection is needed can create a natural barrier, directing squirrels to areas where their behavior is less harmful.

Leveraging Squirrel’s Natural Predators

Encouraging natural predators of squirrels can also be an effective strategy. Installing bird houses or perches for birds of prey can increase the likelihood that these natural deterrents will help manage the squirrel population in your area.

It’s a balance, though, because you want to encourage biodiversity while ensuring your tree-protection efforts aren’t in vain. A healthy ecosystem with predators can create natural checks and balances for squirrel populations.

Modifying Squirrel Behavior Through Training

Though it might seem far-fetched, there have been some anecdotes suggesting that squirrels can be trained, or at least, their behavior can be modified so that they are less likely to strip bark. Using noise devices or even water sprays can create a negative association with approaching certain trees.

However, like many methods, this isn’t guaranteed, and the adaptability and intelligence of squirrels should never be underestimated. Consistency and patience will be your best friends if you attempt to train these clever creatures.

The Economic Impact of Squirrel Damage on Property

It’s important to remember that bark stripping can have an economic impact, particularly if the trees being targeted are part of a commercial orchard or are valuable ornamental specimens.

Investing in prevention and control methods can save substantial costs in the long run by preserving the health and aesthetic value of these trees. It is a situation where proactive expenditure can avert the need for far more costly remedies later on.

Customizing Solutions for Different Tree Species

Keep in mind that not all trees are equally appetizing to squirrels, nor are they equally vulnerable. Crafting protection strategies should involve a customized plan that takes into account the specific types of trees on your property.

Consider the bark texture, growth patterns, and sap sweetness, as these factors can influence squirrels’ choices. Consulting arborists or doing diligent research on your types of trees can make your efforts more effective.


Safeguarding your trees from the natural but potentially destructive behavior of squirrels requires a strategic, multi-faceted approach. By understanding squirrel behavior, implementing a combination of deterrents, and ensuring the health of your trees, you can greatly reduce the risk of bark stripping. Continuous evaluation and adaptation of your methods, along with the collaborative effort in the community, will help protect your green investments for the future.
