Understanding Squirrel Behavior

Squirrels are curious and resourceful creatures that can both entertain and frustrate you in your backyard.

They are an essential part of the wildlife ecosystem, helping to spread seeds and providing food for predators.

To find a solution for your squirrel problem, it’s important to first understand their behavior.

Squirrels are drawn to your backyard by the presence of food sources, such as bird feeders, vegetable gardens, and fruit trees.

You may even inadvertently be creating the perfect environment for squirrels to nest and breed by providing them with hiding places and materials.

Some of their preferred nesting locations are dense shrubs, leaf piles, and woodpiles.

Here are a few aspects of squirrel behavior that explain why they can be challenging to deal with:

  • Diet: Squirrels have an adaptable diet, which means they consume a wide variety of foods, including seeds, nuts, fruit, and tree bark. This adaptability allows them to thrive in your backyard.
  • Climbing and jumping skills: You may have observed squirrels scaling trees, jumping from branch to branch, or even walking along power lines. These acrobatics help squirrels evade predators and allow them access to bird feeders and hard-to-reach areas in your backyard.
  • Problem-solving abilities: Squirrels are intelligent animals known for their problem-solving skills. If they identify a food source, they will innovate ways to access it, often outsmarting the preventative measures put in place.

To reduce squirrel activity in your backyard and keep them at bay, consider incorporating some of these strategies:

  • Limit the food supply: Remove bird feeders, clean up fallen fruit from trees, and secure household garbage in tight containers.
  • Remove hiding places: Keep shrubs trimmed, break down leaf piles, and reduce access to nesting materials.
  • Squirrel-proof bird feeders: Use baffles or purchase squirrel-resistant feeders to make it harder for squirrels to access the birdseed.

While employing these strategies, remember that squirrels are a natural part of the wildlife landscape and living with them harmoniously in your backyard is possible with a few simple adjustments.

Mixing Coffee Grounds with Soil

Using coffee grounds in your garden can greatly benefit your plants.

They are a great source of nitrogen, which is essential for plant growth. To mix coffee grounds with your soil, simply sprinkle used grounds around the base of your plants.

You can also gently work them into the soil to aid with the release of nutrients.

This is especially helpful for vegetables, bulbs, and fruit-bearing plants that require extra nutrients.

Creating a Barrier Around Plants

Another effective way to use coffee grounds in your garden is by creating a barrier around your plants.

This method is particularly useful for keeping squirrels away.

Apply a layer of coffee grounds ½” to 1″ thick on the ground around the area where squirrels are active.

By doing so, you’ll discourage them from digging and nibbling on your plants, while also adding valuable nutrients to the soil.

Coffee Grounds in Composting

Coffee grounds can also be incorporated into your compost. The nitrogen-rich content of used grounds is an excellent addition to any compost pile, while the slight acidity works well for acid-loving plants, such as fruits.

Apply coffee grounds to your compost bin and mix them with other organic matter, like leaves or vegetable scraps, ensuring an even distribution of nutrients.

Your plants will thank you for the rich, nutrient-filled mixture that results from incorporating coffee grounds into your composting process.

Home Remedies

You can also try homemade solutions to repel squirrels.

Some popular home remedies include:

  • Spicy solutions: Create a mixture of water, a few drops of dish soap, and cayenne pepper or hot sauce. Spray this solution on your plants or bird feeders to make them less appealing to squirrels.
  • Essential oils: Squirrels are sensitive to some scents like peppermint, lavender, and eucalyptus. Dilute a few drops of these essential oils in water and spray around your garden or affected areas.
  • Coffee grounds: Spread coffee grounds in a layer ½” to 1″ thick around the area where squirrels are active or in your potted plants that squirrels should avoid and it will keep the squirrels away.

Keep in mind that home remedies may not always be as effective as commercial solutions, but they offer a natural and budget-friendly alternative.

Environmental and Humane Approaches

Some environmental-friendly and humane approaches to controlling squirrel include:

  1. Fencing: Install a squirrel-proof fence around your garden or tree trunks. Ensure the fence is at least 6-foot high, with the top bent outward to prevent squirrels from climbing over.
  2. Protect bird feeders: Use squirrel baffles or guards on your bird feeders to discourage squirrels from stealing the seeds. You can also choose seed mixes that are less attractive to squirrels, such as safflower seeds.
  3. Eliminate food sources: Remove any fallen fruits, nuts, or seeds from your yard to reduce the temptation for squirrels to venture into your property.
  4. Provide alternative food: Set up separate feeders with corn or other squirrel-friendly food away from your garden or bird feeders to divert their attention.

Remember, always consider the impact of your chosen method on the overall wildlife and strive to maintain a balance between protecting your property and being a responsible steward of nature.
