How to Get Rid of Slugs: A Comprehensive Guide

Anyone who has a garden knows how frustrating it can be to see their plants and flowers destroyed by slugs. These slimy creatures can quickly become a real nuisance, leaving holes and trails of destruction in their wake. But fear not – there are plenty of ways to get rid of slugs without resorting to harmful chemicals. In this article, we’ll explore some of the most effective, eco-friendly, and budget-friendly methods for dealing with slugs.


Hand-picking is the tried and true method of removing slugs from your garden. It’s simple, free, and can be done anytime. All you need is a pair of gloves and a container for collecting the slugs.

When picking the slugs, look for them during the early morning or late evening hours, as that is when they are most active. Check underneath leaves, in damp areas, and around shrubs. Once you’ve collected them, dispose of them by placing them in a bucket of soapy water, burying them deep in the ground, or putting them in the compost bin.

The benefits of hand-picking slugs are plentiful. It’s an environmentally friendly method, it’s free, and it allows you to get up close and personal with your garden. Plus, you can make a fun activity out of it by involving your kids or even your pets.

Beer Traps

Beer traps are another popular and effective method for controlling slugs in your garden. The idea is simple – slugs are attracted to beer, so they crawl into the trap, fall in, and drown.

To create a beer trap, bury a container (such as a shallow dish or can) in the soil so the top is level with the ground. Fill the container with beer, leaving a few centimeters of space at the top. Make sure you check the trap regularly and replace the beer when needed.

Some people may wonder if it matters what type of beer you use for the trap. The simple answer is no – slugs are more attracted to the yeast in the beer than the brand. However, it’s a good idea to use cheap beer or beer that is past its expiration date.

While beer traps are effective, there are some downsides to consider. Firstly, you may attract other pests to your garden alongside the slugs. Secondly, it’s not a sustainable method if you are constantly using new containers and beer. Lastly, you may harm non-target animals such as hedgehogs or ground beetles.

Copper Tape/Barriers

Copper tape and barriers work by creating a barrier that slugs do not like to cross. The copper gives the slugs an unpleasant electric shock, which deters them from crossing it.

To use copper tape or barriers, wrap the tape around the base of your pots or place it on the top of raised beds. You can also create a barrier around the edges of your garden by placing copper strips on the ground.

The pros of using copper tape/barriers are that they can be effective and long-lasting. Once installed, you can leave them in place for a long time. However, it can be expensive if you have a large garden to cover, and it may not be practical for everyone.

Coffee Grounds

Believe it or not, coffee grounds can be an effective repellent for slugs. Slugs do not like the acidity of coffee, so spreading coffee grounds around your plants can help keep them away.

To use coffee grounds, sprinkle them in a ring around your plants or mix them into the soil. You can also use espresso grounds instead of regular coffee, and some gardeners recommend crushing up eggshells and mixing them with the coffee grounds for extra effectiveness.

Diatomaceous Earth

Diatomaceous earth is a powder made from the ground-up fossilized remains of tiny aquatic organisms called diatoms. When slugs come into contact with the powder, it cuts them and dehydrates their bodies.

To use diatomaceous earth, sprinkle it around the base of your plants or where you think the slugs are hiding. It’s important to wear a mask when using diatomaceous earth, as inhaling it can be harmful to your lungs.

Although diatomaceous earth can be effective, it does have its limitations. It can be messy to apply, and you may need to reapply it frequently after rain or watering. Additionally, it can harm beneficial insects in your garden if it is not applied carefully.


Salt is a quick and easy way to get rid of slugs, but it does come with some downsides. Salt works by dehydrating the slugs, causing them to die. However, it can also harm plant life if it is overused or applied directly to the plants.

To use salt, sprinkle it on the slugs or create a barrier around your plants. However, be cautious not to use too much salt, as it can build up in the soil and harm the plants.


Nematodes are microscopic worms that can help control slug populations in your garden. They work by entering the slug’s body and releasing bacteria that cause the slug to die.

To use nematodes, mix them with water according to the instructions and apply them to the soil when the weather is warm and damp. The nematodes will attack and kill the slugs, and then reproduce to keep the population under control.

While nematodes can be effective, they do come with a few potential downsides. They can be expensive to purchase, and they may take a few days to work. Additionally, they are sensitive to temperature, and their effectiveness may decrease in areas with extreme heat or cold.


In conclusion, getting rid of slugs from your garden doesn’t have to be a daunting task. By combining a few different methods, you can keep your garden slug-free and healthy. Remember to be environmentally conscious when choosing your method and be cautious not to harm beneficial insects or plant life.
