Squirrels, with their fluffy tails and agile movements, are often seen as charming additions to our gardens. However, beyond their adorable appearance, these creatures can cause significant damage if not managed properly. Understanding the extent of the damage squirrels can inflict helps in creating effective deterrent strategies.
Squirrels' primary sources of damage in gardens include their foraging habits, burrowing tendencies, and chewing behavior. They can target various plants, trees, and even garden structures, causing aesthetic and structural damage. This article explores the different ways squirrels can wreak havoc in your garden and provides insights into prevention and mitigation strategies.
Targeted Plants and Trees
Squirrels have a penchant for certain plants and trees, often drawn to them for food, shelter, or nesting materials. Their foraging can lead to defoliation, damaged fruit, and even uprooted plants.
One of the most significant issues is that squirrels do not limit their diet to specific seasons. They will snack on fruits, flower bulbs, seeds, and even tender shoots throughout the year, leading to sustained damage.
Destructive Foraging
Squirrels' diet includes a wide variety of plant matter. They are partial to fruits, nuts, and seeds, which can lead to complete decimation of crops like berries, grapes, and melons. Moreover, their LIKE, if not love, for flower bulbs can spell disaster for gardens in spring. Tulips, daffodils, and crocuses are favorite targets, leaving holes where once there were blooms.
To make matters worse, squirrels often dig up and discard flowers or plants they deem inedible, further disrupting garden landscapes. They may also strip bark from young trees in search of cambium, the inner bark layer that carries nutrients, potentially killing the tree.
Burrowing Impact
Squirrels, particularly Eastern Gray Squirrels, are adept diggers. They create complex networks of tunnels and chambers under patios, sheds, and foundations, sometimes causing structural damage. These burrows can undermine garden structures, eroding soil and resulting in sagging or cracked surfaces.
Burrowing also poses a risk to trees. Squirrels may create nest holes in tree trunks, allowing water to enter and readers, leading to rot, weakened structures, and potential falls. Moreover, these holes can provide entry points for pests and diseases.
Garden Infrastructure and Structures
Squirrels' chewing and gnawing behavior, driven by the need to keep their front teeth (incisors) wear down, can cause significant damage to garden structures and infrastructure.
Bird feeders, despite their intended function, can attract squirrels. The critters will gnaw through them to access the birdseed, leaving a trail of destruction. Similarly, they may chew on wooden fences, decking, and sheds, causing both cosmetic and structural damage.
Chewing Damage
Squirrels' teeth never stop growing, so they must constantly gnaw to keep them at bay. This behavior, combined with their sharp incisors, makes them formidable chewing machines. Anything from tree limbs to wooden structures can fall victim to their gnawing.
Additionally, squirrels often store food, a practice known as " caching". They may bury nuts and seeds in garden beds, sometimes forgetting their locations. These 'hidden' caches can interfere with garden operations, sprouting where you least expect them.
Nesting Materials
Squirrels create nests for both sleeping and raising young, and they will often use materials from your garden to construct them. Flowers, leaves, and twigs can all be nabbed for nest building, leading to decreased plant coverage and aesthetic damage.
Furthermore, nests can pose a fire risk if located near buildings, especially during dry seasons. Additionally, if a nest is established in your roof or attic, it can lead to pest control issues and potential property damage.
Mitigation Strategies
While squirrels are protected by law in some jurisdictions, there are still numerous humane ways to deter them from your garden. Understanding their behaviors and habits is key to implementing effective strategies.
Timing, placement, and type of plants can make a significant difference in deterring squirrels. Planting flowers and small fruits that aren't favored by squirrels, such as marigolds, impatiens, and pansies, can help minimize damage. Timing your planting to avoid peak foraging seasons can also be beneficial.
Physical Barriers
Creating physical barriers can be an effective deterrent. Fencing made of materials like metal, plastic, or heavy-duty hardware cloth can prevent squirrels from accessing your garden. Consider wrapping the lower half of trees with hardware cloth to protect from bark stripping and nest building.
Placing your bird feeders on a pole with a squirrel-proof feeder or enclosing them in a cage can also help keep squirrels away from the food. Similarly, keeping your compost pile covered can deter squirrels from rummaging through it.
Repellents and Deterrents
Using deterrents can help keep squirrels away. Hot pepper sprays or powders can be sprayed on plants to create an unpleasant scent and taste. However, these should be reapplied after rain or watering.
Ultrasonic wildlife repellent devices, which emit high-pitched noises inaudible to humans but irritating to squirrels, can also be effective. Fragrant plants like lavender, lemongrass, and mint can help repel squirrels, as they dislike strong scents. Regular cleaning of your garden can also deter squirrels by removing food sources and potential nesting sites.
In gardens, prevention is often better than cure. By understanding squirrels' behaviors and habits, garden owners can proactively plan and create spaces that are less appealing, making them less likely to cause damage. Regular maintenance, use of deterrents, and careful consideration of planting times and plants can all play a role in squirrel-proofing your garden.
