How to Make a Beer Trap for Slugs – Pestsyard

Slug control can be difficult, especially if you want to prevent the main cause of slug infestation in your garden. However, there are ways of controlling and killing slugs without resorting to chemicals. One of these methods to consider is beer traps. 

If you’re an avid garden lover, a beer trap for slugs will probably help you in your quest to control these pesky pests in your garden. 

 It is a natural way to control the slug population and stop slug damage on your plants without using chemicals. There are various beer trap designs you can use at your house.

It’s true that beer traps are not the most effective methods to get rid of slugs; however, it works and is effective, so it is worth the try.

They are typically used in vegetable gardens, greenhouses, and at home. Slugs love beer because they are attracted to the yeast in beer, so there is no reason why this method wouldn’t even work in the home garden. Below is everything you need to know about beer traps and some effective alternatives. 

How beer traps work

Do beer traps truly work for slugs, and how does it work? These are some of those questions you want to clarify before going on to use beer traps. There’s a lot of confusion around beer traps, so we’ll clear it up here.

Beer traps work by attracting slugs, which then crawl into the trap and drown. It’s like when a kid who doesn’t know how to swim falls into a swimming pool; they can’t get out until they’re exhausted, so they sit there and drown.

The problem with slug traps is that some people say they don’t work. They say that since slugs are fast and hardy, even if you build a trap for them, they’ll find another way out of your yard.

But this is not true. The only way slugs can escape from the traps is through the same tunnels they used to get into the trap in the first place.

Beer traps will not just keep slugs out of your garden but also prevent them from breeding and moving into surrounding areas. This help keep more than just slugs out of your garden: they can also be used for snails, centipedes, earwigs, and scorpions.

Scientists have tested slug beer traps in labs across the country, and they’ve found that these traps do exactly what they’re supposed to do: they attract slugs and then drown them within their tunnels.

Beer trap for slugs DIY 

Beer traps are a great way to get rid of slugs because they’re not only easy to make, but they also work!

Slugs can cause a lot of damage in the garden. They eat your plants and even damage the fruit, so getting rid of them as soon as possible is important.

If you don’t know how to make a beer trap for slugs, we’ve got you covered with this step-by-step guide. The following are what you need.  

  • A large plastic cup or other containers without a lid
  • Beer

Fill the container halfway and place it on the floor. Dig the floor and let it level with the ground when placing the container on the floor so slugs don’t have difficulty getting into it. You’ll want to place it near the edge of your garden so that slugs will crawl into it easily and fall into the trap.

Why do slugs like beer

Some scientists believe that slugs like beer because of the yeast content. The alcohol content in beer may attract slugs to the brew, but other factors are also at play.

For example, some researchers have suggested that the high sugar content in beer may attract slugs because it’s similar to the sugars found in their natural prey.


The high carbon dioxide levels and yeast in beer may also attract slugs since these levels are similar to those produced by a slug’s own body when it’s breathing oxygen. Below are a lot of reasons why slugs like beer.

  • Beer is rich in carbohydrates and sugars. Slugs like beer because it has a sweet taste, and slugs are notorious for being attracted to sweet things. They’re also attracted to the carbonation bubbles in your beer.
  • Also, beer has a high alcohol content (about 7%), which helps the slug metabolize its food more quickly and efficiently.

How often to change beer in slug traps

The frequency at which you should change the beer in slug traps depends on several factors, including the weather, the number of slugs in your area, and the level of decomposition of the beer.

Here are some general guidelines:

  1. Weather: In warm and wet weather conditions, slugs are more active, so you might need to change the beer more frequently. During cooler and drier periods, they might be less active, and the beer might last longer.
  2. Slug Activity: If you notice that the beer in your slug traps is filling up quickly with slugs, you’ll want to change it more often. Conversely, if the traps are relatively empty, you can leave the beer in longer.
  3. Decomposition: As the beer sits in the slug traps, it will start to decompose and produce an odor. This odor is what attracts the slugs. Once the beer becomes too decomposed and foul-smelling, it will be less effective at luring slugs. Change the beer if you notice a significant change in its smell or appearance.
  4. Trap Design: The design of your slug traps can also impact how often you need to change the beer. Some traps have better protection from rain and debris, which can help keep the beer effective for a longer period.
  5. Beer Choice: Slugs are attracted to the yeast in beer, so you don’t need to use expensive beer. Cheap, non-alcoholic beer works just as well. You’ll want to avoid using beer with a strong odor, as this might deter slugs from entering the trap.

As a general guideline, you might consider changing the beer every 2 to 3 days. Beer traps are used to attract and drown slugs, as they are attracted to the yeast and sugars in the beer. However, the beer can become diluted by rain, lose its attractiveness, or become moldy over time. 

Changing the beer regularly helps to ensure its effectiveness in luring and trapping slugs. Also If the beer has become murky, decomposed, or filled with slugs, it’s time to change it. In some cases, this could be every few days during peak slug activity periods.

Keep an eye on the traps and adjust the frequency of beer changes based on the condition of the beer and the level of slug activity in your garden. If you notice that the beer has lost its effectiveness or has become unpleasant, it’s a good indicator that it’s time to change it.

What to do with dead slugs from beer trap

If you have used beer traps to catch slugs and now have a collection of dead slugs, you have a few options for their disposal.

You can dump them into the soil, as they will be eaten by earthworms, who will then die and decompose. This will fertilize and nourish your soil. Other ways include; 

  1. Composting: If you have a compost bin or pile, you can add the dead slugs to it. They will break down over time and contribute to the compost’s nutrient content.
  2. Garden Waste Bin: Many municipalities have garden waste collection bins for organic materials like plant trimmings, leaves, and small dead creatures. Check if your local waste disposal service accepts this type of organic waste.
  3. Burying: You can bury the dead slugs in a garden bed or an area where you won’t be planting anything soon. Bury them deep enough to discourage scavengers from digging them up.
  4. Feeding Wild Animals: If you have local wildlife that might feed on carrion, you could place the dead slugs in a secluded spot away from your garden. Animals like birds, raccoons, or opossums might consume them.
  5. Freezing and Disposal: Another option is to place the dead slugs in a sealed bag or container and freeze them. This can help prevent odors and decomposition while you wait for your next trash pickup.
  6. Trash Disposal: If none of the above options are suitable, you can dispose of the dead slugs in your regular trash. However, it’s recommended to place them in a sealed bag or container to prevent unpleasant odors.

Remember that if you’re concerned about the use of pesticides or chemicals in your garden, it’s a good idea to avoid using beer traps and instead consider alternative methods for slug control, such as handpicking, creating barriers, or using natural predators like ducks or certain types of beetles.

Best beer for slug trap

I’ve been having a lot of trouble figuring out what beer to put in my slug trap. I’d recommend stout beer. They are high in alcohol content and more likely to attract slugs. We have found that the more alcohol in your beer, the more likely it is to attract slugs and other pests. The right beer for a slug trap is dark, smooth, and easy to drink.

Another good option is a beer, just slightly hoppy. It might sound counter-intuitive, but a hoppy beer will be ideal for a slug’s trap. So if you want to keep your slug trap fresh and working for you, try putting a hoppy beer in it. 

If you’re looking for a good beer that won’t give you a headache after a long day of catching slugs, we recommend going with something dark, like a stout. However, if you’re unsure what kind of beer will work best in your slug trap, try out different beers and see what happens.

Can birds eat beer slugs?

Birds can eat slugs that die in beer traps. Even though the slug is a pest humans have to deal with, it’s important to remember that animals also have to eat. They are both safe for birds and delicious to eat. When you drown slugs in your beer, don’t forget to feed them to your birds.  

Slugs are an excellent protein source and are also packed with vitamins and nutrients. You might have to keep track of how much you feed them, though you don’t want to overfeed them, or they might get sick.

Slugs are common garden pests and can be a nuisance in the garden or on your plants or lawn. They’re known for eating seeds and fruits like tomatoes, cucumbers, and squash.

You may have noticed them hanging out in your garden as well. With this, you can feed your birds with slugs from beer traps, which will make a good meal for them.  

Natural alternative to beer trap for slugs

Coffee Grounds

Coffee grounds are a great way to control slugs because they’re full of nitrogen, which is essential for the slug’s metabolism. It’s also high in caffeine, which can cause the slug to die within 24 hours.

They will kill slugs and snails by dehydrating them. The coffee grounds will attract the slugs because they are tasty and they will crawl into the coffee and die from dehydration.

So, if you want to get rid of your slugs, sprinkle them around your garden. You can also mix them with soil or compost. 

Diatomaceous earth.

Diatomaceous earth is a type of powdery, silica-rich substance that is naturally found in sedimentary rock. It’s used as a natural pest control for many insects, including slugs.

Diatomaceous earth works by releasing tiny shards of sharp edges that slice through the exoskeleton of the slug and kill it on contact. The sharp edges also act as a cutting tool, damaging or even removing the slug’s internal organs and making it easier to remove the slug from your garden.

Beer trap for slugs

Just sprinkle a little diatomaceous earth on the surface of your lawn or garden, and leave it for 24 hours. This will kill any slugs or snails that happen to be on the surface of the soil.

Also, use a fogger with DE inside instead of water when applying insecticides directly onto plants. You can also use DE around outdoor structures like ponds or patios where slugs might be found lurking.

You can also use diatomaceous earth as an alternative to pesticides in your garden, but ensure that you follow all precautions listed on the label for safety reasons.

Use cinnamon

Cinnamon is a natural way to get rid of slugs. It is an effective way to kill slugs because it has an antifungal and antibacterial activity that can kill the slug. The smell of the cinnamon will make the slug run away, so you don’t need to touch it anymore.

Just sprinkle some cinnamon on the ground around your plants, and you’ll have no more trouble with those slimy pests. The cinnamon powder can be mixed with water and sprayed on the soil to kill the slugs.

Sprinkle salt

Sprinkle salt around your house to kill off any slugs that may be lurking. Slugs are repelled by salt, so sprinkling salt around your home and garden will help keep them away. You can also use a mixture of one tablespoon of salt per gallon of water and pour it down drains to kill slugs.

You can use either rock salt, Epsom, or table salt and sprinkle it around the perimeter of your garden.

If you want to be extra safe, you can mix water with salt. The water is there to dilute the salt so that it doesn’t burn your plants too badly if you use it too much, but it also helps keep the slugs from dying too fast when they come in contact with the salt.


Nematodes are a natural way to get rid of slugs. They can be purchased at most garden centers or home improvement stores. Nematodes are microscopic worms that feed on slugs and snails. They work by eating their way through the slug’s outer shell, causing it to die.

The best way to know if your garden is infested with slugs is when you notice them crawling around on the soil’s surface. If you see these little guys, grab a shovel and dig up the area!

Once you’ve dug up the area where they tend to get into trouble, sprinkle some nematodes over it and leave them there for 3-5 days before watering again. In this time frame, they will work their way into the soil and kill any other slugs living there as well.

Slug pellets.

Slug pellets are one of the most effective ways to get rid of slugs. They’re made from powdered lime and sulfur, which, when combined, release hydrogen sulfide gas that kills any slug that comes into contact with it. They’re easy to use: sprinkle some pellets around where you see slugs and wait for them to die from suffocation.

These products come in various forms and sizes, so you’ll want to ensure that you’re using a product designed for the task. The pellets are made from dried fruit and vegetable matter ground into a fine powder.

The grains are coated with potassium salts, which helps them adhere to surfaces where slugs like to hide out. They also contain other nutrients that help your plants grow strong and healthy.

This method has a few advantages over other options. The biggest advantage is that slug pellets are a safe and environmentally friendly way to kill slugs. Slug pellets also work well as a barrier, so they won’t leave any marks on your lawn or plants when you use them.

Another great aspect about slug pellets is that they don’t have any harmful chemicals, so you don’t have to worry about using pesticides that might damage your plants or lawns.

 Let your chickens or duck loose.

If you’re looking for a natural way to rid of slugs, try letting your chickens or ducks loose to eat them. Chickens are great at eating slugs because they have a keen sense of smell and can detect the presence of a slug in their environment. Once a chicken finds one, it will go after it with its beak, which is perfect for removing the slug’s outer shell.

Ducks are also good at eating slugs—they’re more gentle than chickens and won’t get too aggressive with their prey unless they’re hungry enough! Ducks have sensitive taste buds that allow them to enjoy eating things like fish and crickets without harming them (or themselves). Plus, they’re known to be great parents who raise their young well.

You shouldn’t let some of your ducks or chickens loose in your yard if you want to help keep your lawn healthy and pest-free.
