This article will walk you through the process of using slug barrier tape, ensuring you get the most out of this eco-friendly pest control method.

What Is Slug Barrier Tape?

Slug barrier tape, also known as copper tape, is an effective and eco-friendly solution to protect your garden plants from slugs and snails. These pests can cause significant damage to your plants by consuming their leaves and stems.

The tape, typically made of thin copper with an adhesive backing, creates a natural barrier that repels slugs and snails when they come into contact with it. The reason for this repellent effect is that slugs and snails produce a slimy trail, which reacts with the copper, causing an uncomfortable sensation for the pests.

Using slug barrier tape is quite simple, you just need to apply it around the base of your pots, planters, or directly on the soil around your plants. It is important to ensure the surface is clean and dry before applying the tape for maximum effectiveness.

Some key benefits of using slug barrier tape for pest control include:

  • Environmentally friendly: No chemicals or harmful substances are released into the soil.
  • Safe for pets and children: No risk of ingestion, unlike some chemical treatments.
  • Long-lasting: The tape can remain effective for months or even years if maintained properly.
  • Easy to use: The adhesive backing makes it easy to apply without the need for nails or staples.

Selecting the Right Location

The first step in installing a slug barrier tape is to choose the right location. Consider the following factors when selecting an appropriate location:

  • Choose areas where slugs and snails are frequently found, such as near plants, flower beds, or vegetable gardens.
  • Ensure the area receives enough moisture to maintain the tape’s effectiveness but is not prone to excessive waterlogging.
  • Avoid placing the tape near heat sources, as high temperatures can diminish its effectiveness.

Preparing the Surface

To ensure proper adhesion and performance of the slug barrier tape, follow these steps to prepare the surface:

  1. Clear the area of debris, such as leaves, dirt, and rocks.
  2. If applying the tape to a container or raised bed, ensure the surface is clean, dry, and free of oils, greases or residues.
  3. If applying the tape to a wooden surface, consider sealing or painting the wood first to prevent moisture from affecting the tape.

Applying the Tape

Once the surface is prepared, follow these guidelines to apply the slug barrier tape effectively:

  1. Unroll the tape and measure the needed length, leaving a slight overlap at the ends.
  2. Cut the tape with scissors or a sharp blade.
  3. Peel the backing paper and apply the tape to the prepared surface, ensuring it is straight and smooth.
  4. Press firmly on the tape to ensure proper adhesion and eliminate any air bubbles.

By following these installation tips and techniques, the slug barrier tape will serve as an effective deterrent against slugs and snails, protecting your plants and garden from damage.

What Other Barriers Can You Use to Deter Slugs?

While slug barrier tape is an effective method to prevent slugs from accessing your plants, several other barrier options are also available. These alternatives can be used alone or in combination with the slug barrier tape for added protection. Some popular physical and natural slug deterrent options include:

  • Copper Tape: Similar to slug barrier tape, copper tape creates an unpleasant sensation for slugs when they come into contact with it. The tape can be wrapped around plant pots, raised beds, or other surfaces.
  • Eggshells: Crushed eggshells placed around the base of the plants can act as a deterrent as their sharp edges make it uncomfortable for slugs to crawl over them.
  • Gravel or sand: Coarse gravel or sand can be spread around the plants, providing a rough surface that slugs are less likely to cross.
  • Wood ash or sawdust: These materials can be used as a barrier, but they must be replaced frequently, especially after rain.

Some natural predators can also help control slug populations in the garden:

  1. Nematodes: These microscopic worm-like organisms can be introduced to your garden soil to kill off slugs. They are safe for other creatures and the environment.
  2. Ground beetles: Encourage these natural predators by providing shelters, such as rocks or pieces of wood, in your garden for beetles to thrive.
  3. Birds: Birds like thrushes, blackbirds, and robins eat slugs. Provide birdhouses or nesting platforms to attract these slug-eating birds to your garden.

It is important to try and utilize multiple approaches to deter slugs, as they may develop a resistance to a particular barrier over time. Combining different strategies will provide the most effective protection for your plants against slugs.

Alternative Slug Control Methods

While slug barrier tape can be effective, there are other slug control methods available as well. Incorporating a variety of approaches can help to maintain a healthy garden and reduce slug populations. Here are some alternative methods to consider:

  • Beer traps: Set up small, shallow containers filled with beer around your plants. Slugs are attracted to the yeast in the beer and will crawl in and drown.
  • Hand picking: If you’re not squeamish, go out in the evening with a flashlight and handpick slugs off your plants. Be sure to wear gloves and dispose of them properly.
  • Organic slug pellets: Use slug pellets made from iron phosphate or ferric sodium EDTA, which are less toxic to other wildlife and break down into fertilizer.
  • Nematodes: Introduce nematodes, microscopic worms that are natural predators of slugs, into your garden. These can be purchased online or at some garden centers.
  • Copper barriers: Wrap copper tape or mesh around the base of plant pots or raised beds. Slugs receive a mild electric shock from the copper, deterring them from crossing.

Additionally, promoting a healthy garden ecosystem with natural slug predators, such as birds, frogs, and hedgehogs, can help reduce slug populations. Provide suitable habitats and avoid using harsh chemicals that may harm these beneficial creatures.

Since not every method works in every situation, it’s worth trying different approaches and observing what works best for you and your garden. Remember to be patient and persistent in dealing with slugs, as their populations can be controlled over time with consistent efforts.


In summary, slug barrier tape is an effective and non-toxic method for protecting your plants from slugs and snails. By installing the tape correctly and maintaining its effectiveness, you can keep these pests from damaging your garden.

Remember to:

  • Choose a quality slug barrier tape with copper or adhesive properties
  • Clean and dry the surface where the tape will be applied
  • Apply the tape in a continuous line around your plants, pots, or garden beds
  • Check the tape regularly for wear, replacing it when necessary

By following these steps, you can enjoy a healthy and happy garden, free from slug and snail damage.
