organic traps for slugs - Organic Plant Nursery

organic traps for slugs

If you're like me, you love growing plants from seeds and cuttings. There's nothing more satisfying than watching them sprout and flourish in your garden. But there's also nothing more frustrating than finding them nibbled and munched by slugs. These slimy creatures can ruin your hard work in a matter of hours, leaving behind a mess of holes and nibbled off seedling stalks. So as a sustainable gardener, if there's an invasion of the buggers I'm a fan of organic traps for slugs. 

To be clear - I operate in a live and let live ethos - I don't go around hunting for slugs and try to rely on natural barriers and companion planting to deter snails and slugs. The only time I'll actively use a slug trap is when there is a significant amount of seedling in the nursery, because then I've had years when I've lost the whole crop because I've made my garden unnaturally attractive to them.

Check out these other strategies for dealing with slugs though if you'd prefer to deter rather than kill...

I'm not one to resort to harsh chemicals or slug pellets, as they can harm the environment and the wildlife that I'd rather leave happily to their own devices. I prefer to use organic methods that are gentle on the earth and effective on the pests. One of my favourite ways to deal with slugs is to make my own beer traps. They're easy, cheap, and fun to make, and they really work!


Understanding Organic Pest Control

Before we dive into the best way to trap slugs, it's important to understand what organic pest control entails. Essentially it boils down using natural ways to prevent or get rid of pests, without using synthetic chemicals that can pollute the soil, water, and air. It also means respecting the balance of nature and not harming the beneficial insects and animals that help your garden thrive. 

Remember, organic pest control is not just about eliminating pests; it's about creating a balanced ecosystem where all organisms can thrive. So, take the time deciding whether you even want to make slug traps. Maybe growing plants that deter slugs in the first place would be more your bag?

This article is about slug traps, but we also have a popular article on nematodes for slug control, and one about using a non chemical substance called diatomaceous earth that you can use to ward off slugs and snails in your garden.

How to Make Beer Traps for Slugs

Beer traps are simple devices that lure slugs into a container filled with beer, where they drown. The beer attracts them with its yeasty and fermented smell, which they can't resist. Here's how to make your own beer traps:

What You'll Need

  • Empty jam jars or similar containers
  • Beer (any kind will do but the yeastier the better!)
  • Active dry yeast (optional, but it makes the trap more effective)
  • A sharp knife or scissors
  • Small sticks or branches
  • Rocks or boards

How to Set Up Slug Traps

  1. First, you need to find out where the slugs are hiding and feeding in your garden. Look for signs of damage or slime trails on your plants, especially in damp and shady areas. You can also go out at night with a torch and spot them crawling around...Fun times!
  2. Next, you need to dig a small hole and place the jam jar in it, so that the rim is about two inches above the ground level. This is important, as it prevents other insects from falling into the trap, such as bees and ladybirds, which are good for your garden.
  3. Then, you need to fill the jar with about three inches of beer. Don't fill it too much, as the slugs might be able to climb out. If you have some active dry yeast, you can sprinkle a little bit into the beer, to make it more potent and smelly.
  4. Finally, you need to cover the jar with a lid that has a small hole cut in it, or prop up the lid with some sticks or branches, to create a gap for the slugs to enter. You can also use a rock or a board as a roof, to protect the trap from rain and sun.

How to Bait Slug Trap

Why do slugs like beer traps? The Smell! Fill the container with about 3 inches of beer, which acts as an effective slug bait due to the odour. The yeast and fermentation smells draw slugs into the trap. However, be mindful not to overfill the container, as this can make it easier for slugs to escape. If available, sprinkle a little active dry yeast into the beer. This step is not essential, but it increases the effectiveness of the trap by enhancing the fermentation scent, which is irresistible to slugs.

Is there an Alternative to Beer in Slug Traps?

  • Yeast and Sugar Solution: Mix water, yeast, and sugar to create a solution that attractS slugs. While it may not be as effective as beer, it can still lure them into the trap.
  • Fruit Juice:Try citrus-based fruit juice as an alternative to beer. The sweetness can attract slugs.


How to Maintain the Traps

  • Check the traps every day or two, and remove any dead slugs that you find. You can dispose of them in the compost bin, or feed them to the birds, if you're feeling generous.
  • Replace the beer every two or three days, as it loses its smell and effectiveness over time. You can use the old beer as a fertiliser for your plants, as it contains nitrogen and minerals. 

where to place beer slug traps

Deciding where to place beer slug traps can be a trial and error process -Move the traps around your garden, to catch more slugs and prevent them from getting used to them. Experiment with different locations and see what works best for you.

Enjoy Your Slug-Free Garden!

By using these simple and organic beer traps, you can reduce the slug population in your garden and protect your plants from their damage. You can also enjoy the satisfaction of making your own pest control solution, and saving money and resources in the process. And who knows, you might even have some fun along the way!

Happy gardening!
