Slugs and snails are known to be destructive pests that can cause significant damage to plants cultivated in raised beds. To control slugs, it is essential to clean up your garden, turn your compost bin, and use proven methods to keep them away without harming your plants. To ensure the purity and quality of the filling material, divide, thin out, and space plants adequately for better air circulation. Prune lower leaves and branches to prevent slugs from entering the bed.
One easy way to keep slugs out of raised beds is to create a copper collar around the outer edge of the bed by stapling or nailing a strip of copper tape or strips around the top of the bed. This will help keep the soil dry enough to dissuade slugs.
To create a slug barrier for your raised bed, run a bead of adhesive along the top of your raised bed or garden containers and roll the zinc or copper strip along the adhesive, nailing in place every 2-3 feet. Cut the strip at the corner.
Organic slug killers include placing a cup, tub, or container into the soil with the lip level with the soil and filling it with lager or beer. Learn effective slug control techniques on Vegogarden’s blog and consider using a DIY electric slug fence with a 9volt battery to stop slugs from getting in.
Sowing and planting in a raised bed can slightly reduce the risk of slug damage. Avoid using wood chip mulch in vegetable fields as it provides a safe haven for snails and slugs. Popular barriers include ash, bark, cat litter, cocoa chips, sawdust, sand, horticultural grit, wool pellets, or coffee.

What smell do slugs hate?
Aromatic herbs like mint, sage, thyme, basil, parsley, and rosemary are effective repellents for slugs and snails due to their strong scents. These plants can be planted anywhere in the garden, either in pots or directly into the ground. They can be placed next to other plants to protect the rest of the garden. Tussock grasses are also a great slug and snail repellent due to their dry and spindly nature.
They can be used to create a low border around vulnerable plants to prevent slimy irritants from accessing their food. Strongly-scented flowers like lavender, peonies, roses, and geraniums can add color and prevent damage caused by slimy pests while keeping the garden smelling delightful.
How do I control slugs in my garden naturally?
Homemade snail and slug repellents can be created by mixing garlic or coffee grounds with water in a spray bottle. This mixture is applied to plants and the surrounding ground to deter slugs and snails. Sacrificial plants, or trap plants, can help protect gardens by attracting pests elsewhere. For example, lettuce can be planted at the back or in inconspicuous spots to attract slugs and snails. Additionally, citrus traps can be created by scattering lemon, lime, orange, and grapefruit peels upside down in the garden before night. In the morning, slugs and snails will find these treats and collect them, moving them at least 20 feet away from the garden.
How can I stop slugs coming into my garden?
Sharp grit, ash, and bark can help ringfence plants, preventing slugs from crossing over. Other mulch materials include wood pellets, cat litter, and coffee grounds. However, these methods don’t completely eliminate slug risk. Newspaper can be used as a temporary shelter for slugs, and collected at the end of the day. Seaweed, collected at the beach, acts as a natural slug repellent and is beneficial for soil and plants. Mulch seaweed around the plant bed, ensuring it doesn’t come in direct contact with the plant stems.
What does vinegar do to slugs?
To deter the presence of snails and slugs in one’s garden, the use of a vinegar spray, comprising a solution of water and vinegar, is recommended. This should be applied in the evening. The spray, which has a mild acidic quality, is effective in killing snails and slugs but is toxic to vegetation. Additionally, an ammonia spray, composed of water and ammonia, can be employed. The use of coffee grounds around plants has been demonstrated to be an effective method for deterring slugs and snails, as they are unable to tolerate caffeine.
What is a natural homemade slug repellent?
A garlic spray recipe entails the combination of water, chopped garlic, onion, cayenne pepper, and soap. The mixture should then be allowed to marinate in a spray bottle for several days, after which the water should be strained and mixed with the pepper and soap. To prevent the mixture from clogging, it is advisable to strain it through a coffee filter or a cloth napkin.
Will sprinkling salt deter slugs?
Salt can repel slugs, but it may not be suitable for plants that prefer maritime conditions. Seashells, with their sharp edges, deter slugs but don’t decay like eggshells. Slug pellets, which are not organic and can kill predators, are not wise to use. When slugs die, predators leave, leaving the plant dependent on the pellets. Ludwig Appeltans, a permaculture designer and teacher, advises against these methods.

How to stop slugs in raised beds?
To deter slugs from reaching your plants, consider using self-adhesive copper tape. Copper reacts with slug slime, providing a small electric shock. Plants like Astrantia, wormwood, rue, fennel, anise, and rosemary can also deter slugs. Remove potential slug shelters, such as bricks, furniture, and logs, to expose them to natural predators. This will make your garden an unsuitable habitat for slugs to survive, reducing the problem naturally.
Encourage natural predators like toads, newts, hedgehogs, and song thrushes to take care of the problem. By following these tips, you can effectively control slugs and prevent their damage to your garden.
What is the best slug deterrent?
The combination of garlic, lawn chamomile, and chives has been demonstrated to repel slugs and snails. This effect can be achieved through the planting of these plants together or through the use of their extracts. The use of garlic represents a natural method of pest control, while the application of chives in the form of a tie around vulnerable plants has been demonstrated to be an effective approach.
Lawn chamomile seedlings have been observed to be more attractive to slugs and snails, which makes them more challenging to deter. Such plants may be planted in a concealed manner and subsequently deployed when required.
How to stop slugs from eating plants naturally DIY?
Eggshells and coffee grounds can be used as natural pest control in gardens by creating an unwelcome texture for these pests. These nutrients add a win-win situation for soil health. Apply ground eggshells and coffee grounds in a thin layer between rows or around the base of plants to protect them. Garlic is another natural alternative for slug and snail control. Mixing garlic and water in a spray bottle acts as a strong repellent for these pests.
However, caution should be exercised when applying this method, as delicate leaves may burn easily if the mixture is too astringent. This method is not available in AZ, CA, HI, NV, and UT, but a comparable product can be found.

It looked to me as if at the end the slug was getting bolder – it might change behaviour if it gets used to the current. I think it would be a better test to create a two loop electric pen and put slug in centre and see if it escapes – if it stays in centre for ages ( perhaps left unattended ) you know the effectiveness does not die down with time. See other Youtube article to get the idea of an “electric pen” search for “Copper Tape Slug Repellent Test” on Youtube – guy basically used copper tape to make an enclosure. I am suggesting two concentric copper wire circles – not touching and then connect to battery.
