Moles might be small, but their impact on a garden can be significant. With their constant burrowing, they create unsightly mounds of soil, disrupt plant roots, and can leave your carefully maintained garden looking like a battlefield. If you’re dealing with these underground visitors, there are ways to manage the problem effectively while keeping your outdoor space thriving.

Understanding moles and their behaviour
Moles are not rodents but insectivores, meaning their primary diet consists of earthworms, grubs, and other small insects. Their tunnelling habits help aerate the soil, which can be beneficial, but the destruction they leave behind often outweighs any advantages. Because they are solitary creatures, spotting multiple molehills does not necessarily mean an infestation—just one or two moles can cause substantial damage.
Signs of mole activity
Before taking action, it’s essential to confirm that moles are indeed the culprits. Look for raised ridges of soil that indicate tunnels just beneath the surface, as well as conical mounds of dirt where moles have pushed excess soil to the surface. Unlike other burrowing pests, moles do not eat plants, so if you notice missing leaves or chewed roots, another pest may be at work.
Natural deterrents to keep moles away
A humane approach to mole control is to make your garden less appealing to them. Moles dislike strong smells, so planting deterrents such as marigolds, daffodils, or alliums around your garden can help drive them away. Additionally, castor oil is an effective, natural mole repellent. Mixing it with water and spraying it over affected areas can make the soil unpleasant for them without harming other wildlife.
Encouraging natural predators
Owls, hawks, and snakes are natural mole predators. Encouraging these creatures into your garden by installing owl boxes or maintaining natural habitat areas can help keep mole populations in check. However, if you have pets, be mindful of attracting predators that might pose a risk to them as well.
Disrupting their tunnels
Since moles prefer quiet, undisturbed environments, frequently flattening their tunnels or disturbing their burrows can encourage them to move elsewhere. Stamping down raised ridges and filling molehills with soil regularly can be an effective method over time.
Trapping and professional removal
If natural deterrents and disruptions do not work, trapping is an option. Humane mole traps can be placed along active tunnels to catch and relocate them. However, this method requires patience and frequent checking. If the problem persists, professional pest control services can assess the situation and provide solutions tailored to your garden’s specific needs.
Preventing future mole invasions
Once you have managed to rid your garden of moles, taking preventive measures can help ensure they don’t return. Reducing the number of grubs and insects in your soil makes the area less attractive to moles. Proper lawn maintenance, including regular aeration and drainage management, can also make your garden a less inviting habitat.
Dealing with moles requires persistence, but with the right combination of deterrents, natural solutions, and preventive measures, you can reclaim your garden without resorting to harsh chemicals or inhumane methods. With patience and a little strategic effort, your outdoor space can remain a beautiful, mole-free zone.
