Are ground squirrels turning your garden into a buffet and your yard into a minefield of holes? These seemingly cute critters can quickly become a destructive nuisance, causing significant damage to lawns, gardens, and even the foundations of buildings. Their constant digging disrupts plant roots, weakens structures, and can create hazardous tripping points. Managing a ground squirrel population is essential not only for protecting your property but also for preventing potential conflicts with pets and the spread of diseases.
Dealing with ground squirrels requires a strategic approach that considers both humane and effective methods. Ignoring the problem will only lead to its escalation, resulting in more extensive damage and a larger infestation. Understanding ground squirrel behavior, identifying the signs of their presence, and implementing appropriate control measures are crucial for reclaiming your outdoor spaces and restoring peace of mind. This guide provides valuable insights and proven techniques to help you take back control of your yard.
What are the most effective and humane ways to get rid of ground squirrels?
What are the most humane ways to get rid of ground squirrels?
The most humane ways to get rid of ground squirrels prioritize preventing them from accessing your property and employing exclusion techniques rather than lethal methods. This focuses on making your yard unattractive to them, physically blocking their access to gardens and burrows, and, when necessary, using live traps for relocation, ensuring you follow local regulations and relocate them to a suitable habitat far from your property and others.
Employing a combination of habitat modification and exclusion is key to humane ground squirrel control. Start by removing food sources: clean up fallen fruits and seeds, secure garbage cans, and store pet food indoors. Consider replacing grass with less desirable ground covers like gravel or mulch, which ground squirrels dislike digging in. Protect vulnerable plants with wire mesh cages or netting. Fencing can also be effective; bury hardware cloth at least 12 inches deep to prevent them from burrowing underneath. Regularly disrupting their burrows by filling them with gravel or soil can also discourage them, but ensure no squirrels are inside before doing so. If these methods are insufficient, live trapping may be considered. Choose traps specifically designed for ground squirrels and bait them with sunflower seeds, peanut butter, or oats. Check the traps frequently, ideally twice a day, to minimize stress for the trapped animals. Relocation is where ethical considerations are paramount. Contact your local animal control or wildlife authorities to understand the legal requirements for relocation and identify suitable release sites. Releasing them on someone else’s property is generally illegal and simply transfers the problem. Release sites should be far enough away (several miles) to prevent their return but close enough to a suitable habitat where they can find food and shelter. Keep in mind that relocation can be stressful for the animals, and survival rates can be low if the new environment is already populated with other ground squirrels.
Will traps alone be enough to control ground squirrel populations?
Trapping can be an effective method for controlling ground squirrel populations, especially for small infestations or when other methods are not feasible. However, relying solely on traps is often insufficient for long-term, widespread control because ground squirrels reproduce quickly, are wary of traps, and new individuals can readily move into vacant territories.
Trapping requires significant time and effort, as traps need to be set, monitored, and re-baited regularly. Success depends on selecting appropriate trap types (e.g., body-gripping traps, live traps), using attractive baits (e.g., peanut butter, seeds), and placing traps in areas with high ground squirrel activity. Even with diligent trapping efforts, you may only be removing a fraction of the overall population, especially if the infestation is large. Surviving ground squirrels may also learn to avoid traps. For larger infestations or in areas where rapid population reduction is necessary, an integrated pest management (IPM) approach is more effective. IPM combines trapping with other control methods such as habitat modification (removing food sources and vegetation), exclusion (using fencing), and, in some cases, rodenticides (when permitted and applied by professionals). By combining multiple strategies, you can achieve more comprehensive and sustained control of ground squirrel populations. Focusing only on trapping will likely lead to a recurring problem.
Are there plants that naturally deter ground squirrels?
Yes, certain plants are known to naturally deter ground squirrels due to their strong scents or toxic properties. Planting these around vulnerable areas can help create a less appealing environment for these rodents, reducing their presence and the damage they cause.
Several plants possess characteristics that ground squirrels find unpalatable or even dangerous. Strong-smelling herbs like mint (especially peppermint), rosemary, lavender, and catmint are often effective deterrents. Ground squirrels have a highly sensitive sense of smell, and these intense aromas can overwhelm them, discouraging them from foraging or nesting nearby. Members of the Allium family, such as garlic, onions, and chives, also emit pungent odors that ground squirrels tend to avoid. Beyond scent, some plants contain toxins that make them undesirable to ground squirrels. Daffodils, for instance, contain alkaloids that are poisonous to many animals, including squirrels. While planting poisonous plants requires careful consideration to avoid harming pets or children, they can be a valuable component of a comprehensive ground squirrel control strategy. Consider strategically interplanting these deterrent plants with other garden favorites to protect them from ground squirrel damage. When using plants to deter ground squirrels, remember that effectiveness can vary depending on the specific species of ground squirrel, the availability of other food sources, and the overall environment. It’s best to combine plant-based deterrents with other control methods, such as physical barriers or trapping, for the most successful outcome.
How do I prevent ground squirrels from digging under my house?
Preventing ground squirrels from digging under your house requires a multi-pronged approach that combines physical barriers, habitat modification, and, when necessary, professional intervention. Focus on making your property less attractive to them and blocking their access to vulnerable areas beneath your home.
Ground squirrels are attracted to areas with easy access to food and shelter. Start by eliminating potential food sources around your house. This includes picking up fallen fruit from trees, securing garbage cans with tight-fitting lids, and storing pet food indoors. Consider removing bird feeders, as they provide an abundant food source for ground squirrels. Next, modify the habitat around your foundation. Clear away dense vegetation, wood piles, and other debris that provide cover and nesting sites. Keep grass short and trim shrubs away from the house. These actions will make your property less inviting to ground squirrels. The most effective long-term solution is creating a physical barrier to prevent access under your house. This usually involves using hardware cloth (a sturdy wire mesh with small openings) to block entry points. Dig a trench around the perimeter of your foundation, approximately 12 inches deep and 6 inches wide. Install the hardware cloth vertically in the trench, ensuring it extends at least 6 inches below ground level and 12 inches above ground. Bend the underground portion of the mesh outward at a 90-degree angle to deter digging. Backfill the trench, burying the mesh securely. Inspect your foundation regularly for cracks or holes and repair them promptly. Any openings, even small ones, can provide an entry point for determined ground squirrels. Consider consulting with a wildlife control professional for severe infestations or if you are uncomfortable handling the trapping or exclusion process yourself. They can assess the situation and implement a tailored plan to effectively manage the ground squirrel population around your property.
What are the risks of using poison to eliminate ground squirrels?
Using poison to control ground squirrel populations carries significant risks, primarily involving unintended harm to non-target animals, environmental contamination, and potential health hazards to humans and pets.
Poisoning ground squirrels can have devastating consequences beyond the targeted pests. Birds of prey like hawks and owls, along with other wildlife such as foxes, coyotes, and even domestic pets, can consume poisoned squirrels or baits directly. This can lead to secondary poisoning, causing illness, death, and disruption of the local ecosystem. Furthermore, the poisons used often contain anticoagulants, which cause internal bleeding, leading to a slow and agonizing death for both the targeted and non-targeted animals. The improper application or disposal of poison baits can contaminate soil and water sources. This can impact the health of local flora and fauna and potentially contaminate drinking water supplies. Moreover, children and pets may accidentally ingest the poison, leading to serious health complications or even death. Even if used “according to the label,” unforeseen environmental conditions like rain can redistribute the poison beyond the intended treatment area. Ultimately, while poison may seem like a quick fix, the associated risks often outweigh the benefits. Safer and more humane methods of ground squirrel control, such as trapping, habitat modification, and exclusion techniques, should be prioritized to minimize harm to the environment and non-target animals.
How can I tell if I have ground squirrels versus other burrowing pests?
Distinguishing ground squirrels from other burrowing pests relies on observing their physical appearance, behavior, and the characteristics of their burrows. Ground squirrels are typically diurnal (active during the day), have short, bushy tails which they often hold erect, and their burrows usually have multiple entrances and exits. Other pests like gophers, moles, or voles differ in these characteristics, offering key clues to identification.
Ground squirrels are often confused with chipmunks, but chipmunks have distinctive stripes running down their back and tend to be smaller. Gophers, on the other hand, are often solitary, create mounds of dirt around their burrow entrances, and are generally nocturnal. Moles leave raised ridges on the surface of the ground and their burrow entrances are difficult to spot because they’re created from beneath the soil. Voles create shallow tunnels just beneath the surface, leaving tell-tale trails in grass or snow. Beyond physical appearance and behavior, examine the burrow entrances. Ground squirrel burrows are generally 2-4 inches in diameter and kept relatively clean of debris. Fresh droppings near the entrance can also point to ground squirrels, as can the presence of small nuts, seeds, or other food items cached nearby. The number of entrances also matters; ground squirrel colonies establish complex systems with many entrances and escape routes, unlike the single-entrance tunnels favored by some other burrowing animals. If you see the animal actively foraging during the day, upright and scanning its surroundings, and disappearing into a hole in the ground, it’s highly likely you’re dealing with ground squirrels.
What’s the best long-term solution for ground squirrel control?
The most effective long-term solution for managing ground squirrel populations involves an integrated pest management (IPM) approach. This means combining multiple control methods strategically, focusing on habitat modification, exclusion techniques, and, when necessary, targeted population reduction while minimizing harm to non-target species and the environment. Relying solely on one method usually provides only temporary relief, as ground squirrels are adaptable and populations can quickly rebound.
A successful IPM strategy starts with habitat modification. Ground squirrels thrive in areas with abundant food and easy access to burrows. Reducing food sources, such as spilled birdseed, fallen fruit, and readily available garden crops, can make your property less attractive. Regularly mowing lawns, clearing weeds, and removing brush piles eliminates cover that ground squirrels use for protection from predators. Consider replacing ground cover that provides easy burrowing with less suitable materials like gravel or paving. Altering irrigation practices to avoid oversaturation of the soil can also make the area less appealing for burrowing. Exclusion techniques offer another important layer of defense. Fencing, particularly hardware cloth with a mesh size of ¼ inch or smaller, can be used to protect vulnerable gardens or individual plants. The fence needs to be buried at least 12 inches deep, with an additional 6 inches bent outward to prevent ground squirrels from digging under it. For fruit trees, consider using trunk wraps or tree guards to prevent climbing. While these exclusion methods are effective for specific areas, they are typically not practical for large properties. Ultimately, a combination of these approaches, tailored to your specific property and ground squirrel population, will provide the most sustainable and humane control over time.
