Controlling garden pests like slugs and snails is a common challenge for many. While various methods exist, some gardeners prefer solutions that are safe for other wildlife and plants. For instance, certain products like slugrings are designed not to harm the molluscs but deter them through an unpleasant reaction with their slime. This approach allows slugs and snails to remain in the ecosystem, providing a food source for their natural predators. Attracting these predators is an excellent, natural way to help keep slug and snail populations in check. This leads to a key question for environmentally conscious gardeners: What Animals Eat Slugs And Snails? Most people know that birds and hedgehogs are common predators, but a variety of other creatures also include these garden pests in their diet. Understanding these natural enemies can help you create a more balanced garden ecosystem.
Amphibians
All native frogs, toads, and newts in many regions will readily consume slugs and snails. Their diet is generally limited by size – if they can fit the mollusc into their mouth, they will eat it. Larger, more mature amphibians are capable of tackling bigger slugs and snails. When working in areas with long grass or digging, it’s wise to be mindful to avoid injuring any amphibians present. Creating a pond, even a small one like a buried bucket or old sink, can significantly attract these helpful predators. Ensure any water feature includes oxygenating plants and provides easy access in and out of the water for wildlife.
Reptiles
Certain reptiles like slow worms and common lizards also feed on slugs. You can help attract them by leaving undisturbed areas in your garden with piles of leaves or woody debris. These spots provide shelter and hunting grounds. For instance, finding slow worms under a compost area highlights how these creatures utilize such habitats. Careful handling and preserving their environment when making garden changes can encourage them to stay.

Birds
While not all bird species consume slugs and snails, many slightly larger garden birds do. Notable examples include thrushes, blackbirds, robins, starlings, gulls, jays, magpies, and owls. Attracting birds is relatively straightforward: providing food is a primary draw. Adding a birdbath, installing nesting boxes, and maintaining undisturbed trees or shrubs will create a welcoming habitat for avian predators. Besides slugs and snails, many of these birds also help control other garden pests, offering multiple benefits.

Insects
Several insect species are valuable predators in the garden, specifically targeting slugs and their eggs. Ground beetles and rove beetles are key examples, with hundreds of species found in various sizes. These common garden inhabitants are particularly effective at eating tiny slug hatchlings, which can devastate young plants rapidly. Active primarily from spring through autumn, you can encourage these beneficial insects by leaving areas of uncut grass or planting wildflowers, providing them with suitable habitats.

Mammals
A surprising number of mammals include slugs and snails in their diets. Hedgehogs are perhaps the most well-known, but shrews, mice, moles, squirrels, and even foxes will also consume them. Similar to attracting other wildlife, leaving small patches of your garden with longer grass, undisturbed hedges or banks, and wood piles can provide the necessary cover and habitat to draw in these mammalian predators.
Parasites
Among the smallest yet most effective slug predators are nematodes, or eelworms. These microscopic, naturally occurring soil dwellers are parasitic to slugs. They enter the slug’s body and introduce bacteria that cause the slug to decompose from within. Specific types of nematodes are now commercially available as a biological control method and can be a great organic option, potentially used in combination with deterrents like slugrings for comprehensive slug control.

Conclusion
Controlling slugs and snails in your garden isn’t about finding a single, quick fix, nor should it be about complete eradication. Slugs, in fact, play a role in the garden ecosystem as decomposers. A balanced approach is often the most sustainable, relying on natural predators to help keep numbers in check. By understanding What Animals Eat Slugs And Snails and creating a welcoming habitat, you can attract a diverse range of wildlife – amphibians, reptiles, birds, insects, mammals, and even microscopic nematodes – to act as your garden’s natural pest control team. This fosters a healthier, more resilient garden environment where both plants and wildlife can thrive.
