Tips to Get Rid of Garden Snails & Slugs
If you’ve seen slimy trails in your garden or noticed damage to your plants, you probably have snails or slugs. These pests can harm your plants, especially soft greens and young seedlings, leaving holes and marks. But don’t worry, there are many ways—both natural and chemical—that can help get rid of them. In this guide, we’ll share different methods to control and even remove snails and slugs, helping keep your garden healthy and growing strong.
Understanding Snails & Slugs
What are Garden Snails and Slugs?
Garden snails and slugs are soft creatures that belong to a group called mollusks. The main difference is that snails have shells, while slugs don’t. Both are known for leaving slimy trails behind and eating a lot. They mostly come out at night or on damp, cloudy days when the weather is perfect for them.
Why Snails and Slugs are a Threat to Your Garden
Snails and slugs love to eat soft plants, especially when they are young. They can create holes in leaves, flowers, and even stems, which weakens the plants and makes them more likely to get sick. Some snails and slugs can be especially harmful to crops like lettuce, cabbage, and tomatoes. Besides damaging plants, their slime can make your garden look messy and unattractive.
Signs of Snail and Slug Infestation
How to Identify Snail and Slug Damage in Your Garden
To spot snail and slug damage, look for irregular holes in leaves, especially around the edges. You might also see slimy, shiny trails they leave behind, especially on damp surfaces or on plants early in the morning. Snails and slugs prefer eating soft, tender plants over tougher ones, so focus on these areas when checking for damage.
Common Plants that Attract Snails and Slugs
Snails and slugs love to eat leafy greens, young vegetables, and flowers like hostas. They also tend to target seedlings, so it’s especially important to protect young plants while they are still growing.

Preventing Snails and Slugs in Your Garden
Creating a Garden Environment that Discourages Snails and Slugs
The best way to manage snails and slugs is to prevent them from coming in the first place. These pests love moist, sheltered spots. By keeping your garden dry, tidy, and free of clutter, you make it less attractive to them.
Importance of Proper Garden Maintenance
To keep snails and slugs away, trim your plants, remove fallen leaves, and clear any piles of debris or compost where they could hide during the day. A clean and well-maintained garden gives them fewer places to shelter, making it harder for them to thrive.
Physical Barriers Against Snails & Slugs
Using Copper Barriers or Strips to Repel Snails and Slugs
Copper is a natural and effective way to keep snails and slugs away. When these pests touch copper, they feel a mild electrical charge that makes them turn back. You can buy copper mesh or strips to place around your plants or garden beds. It’s an eco-friendly and long-lasting solution to protect your garden.
Creating Raised Beds and Mulching to Reduce the Risk of Infestation
Building raised garden beds or adding mulch can help keep snails and slugs out. Raised beds make it harder for them to crawl into your plants, while mulch, like wood chips or gravel, creates a rough surface that they don’t like to move across. This helps reduce the chance of an infestation in your garden.
Natural Remedies to Get Rid of Snails & Slugs
Using Eggshells, Diatomaceous Earth, and Coffee Grounds as Natural Deterrents
Eggshells: Crushed eggshells create a sharp, rough surface that snails and slugs don’t like. Sprinkle them around the base of your plants to form a barrier that they’ll avoid.
Diatomaceous Earth: This fine powder, made from fossilized tiny aquatic creatures, is safe to use around plants. It works by damaging the soft bodies of snails and slugs, causing them to dry out and die.
Coffee Grounds: The caffeine in coffee grounds is toxic to snails and slugs. By sprinkling used coffee grounds around your plants, you can create a natural repellent to keep them away.
Encouraging Natural Predators Like Birds, Frogs, and Beetles
Bringing natural predators into your garden is a great way to keep snail and slug numbers in check. Birds, frogs, toads, and beetles love to eat these pests. You can attract them by adding features like birdhouses, ponds, or even piles of rocks to give them a safe place to live and hunt.
Chemical Methods for Slug and Snail Control
Types of Slug and Snail Bait: Pros and Cons
There are different types of chemical baits for snails and slugs, most containing metaldehyde or iron phosphate. While these baits can be effective at reducing pest populations, they can also pose risks to pets, wildlife, and helpful insects. Always be cautious when using them, and carefully follow the manufacturer’s instructions to minimize harm to your garden’s ecosystem.
How to Apply Slug Pellets Safely and Effectively
To apply slug pellets properly, do so in the evening when snails and slugs are most active. Scatter the pellets around the base of your plants or along garden paths where pests are likely to travel. Be mindful not to use too many pellets, as overuse can harm the environment and non-target animals.
Organic Chemical Alternatives
Safe, Organic Alternatives Like Iron Phosphate-Based Baits
Iron phosphate-based baits are a safer, organic alternative to traditional chemical baits. They are much less harmful to pets, wildlife, and beneficial insects. These baits work by stopping snails and slugs from feeding, which eventually leads to their death. This makes iron phosphate a more eco-friendly option for controlling these pests while protecting your garden’s health.
Habitat Modification to Reduce Slug & Snail Populations
Removing Hiding Spots and Managing Moisture
Snails and slugs like to hide under damp things like rocks, plant pots, and piles of leaves. By removing these hiding spots and keeping moisture levels in check, you can make your garden less inviting for them.
Proper Irrigation Practices
Watering too much or letting areas stay wet for too long can attract snails and slugs. It’s a good idea to use a drip irrigation system and only water when needed to keep your garden healthy without drawing in pests.
Maintaining Long-Term Control Over Snails & Slugs
Regular Monitoring and Garden Inspections
To keep snails and slugs under control, it’s important to regularly inspect your garden. By checking your plants often, especially after rainy weather when these pests are most active, you can spot infestations early and take action before they cause too much damage.
Preventing Re-Infestations: Seasonally Managing Your Garden
Snails and slugs tend to be seasonal pests, so adjusting your methods based on the time of year is key. Regular garden maintenance and staying vigilant throughout the seasons will help prevent re-infestations and keep your garden safe from these pests.
Soil and Garden Health for Long-Term Success
Enhancing Soil Health to Discourage Snails and Slugs
Snails and slugs prefer damp, poorly-drained soil. By improving your soil with organic matter, such as compost, you help your plants grow stronger and create an environment that is less inviting to these pests. Well-draining soil not only supports healthy plants but also makes it harder for snails and slugs to thrive.
The Importance of a Balanced Ecosystem in Your Garden
Creating a balanced ecosystem in your garden with a mix of plants, insects, and animals is important for controlling pests. Having natural predators, such as birds, frogs, or beetles, will help keep snail and slug populations in check without needing to rely on chemicals. A diverse garden is a healthier garden for both plants and wildlife.
Common Myths About Snails and Slugs
Debunking Myths: What Really Works and What Doesn’t
Many gardeners believe that salt is a quick solution to kill snails and slugs, but this method can actually do more harm than good. It’s important to understand what works and what doesn’t to ensure the long-term health of your garden.
The Truth About Using Salt and Its Impact on the Garden
While salt may kill snails and slugs on contact, it also harms the soil. Salt can disrupt the soil structure, making it difficult for plants to absorb water and nutrients. Over time, this can stunt plant growth and damage the overall health of your garden. Instead of using salt, try safer alternatives like traps, physical barriers, or natural deterrents that won’t harm your plants or the environment.
