How to get rid of slugs in the cellar

Slug infestations in cellars can be a chronic annoyance, particularly if ignored. These slimy organisms are drawn to damp, cool spaces like cellars because they can grow and proliferate there. They can contaminate surfaces and harm stored goods in addition to being unsightly. Thankfully, there are efficient ways to control and get rid of slugs, so your cellar stays tidy and slug-free.

Taking out the slugs’ favorite places to live is one of the easiest ways to keep them out of your cellar. Since slugs like damp conditions, check your cellar for leaks or other sources of moisture before doing anything else. Reducing humidity levels and enhancing ventilation can help make the environment less hospitable for slugs. To keep things dry and prevent slugs from moving in, you should also think about using a dehumidifier.

Clearing out any organic debris or clutter from your cellar is another smart move. Since slugs are drawn to decomposing plant matter, you can keep them from having easy access to your cellar by removing mulch, leaves, and other organic materials from near entrances. To reduce potential hiding places for slugs, make sure that stored items are kept off the floor and in sealed containers inside.

To be more proactive, you can keep slugs out of your cellar by using barriers and natural repellents. Slugs are hesitant to cross barriers created by common household items like coffee grounds, salt, and diatomaceous earth sprinkled around entry points. Copper tape around windowsills and doorways works well too, giving slugs a small electric shock upon contact to discourage them from going inside.

Use of traps or baits to lower the slug population should be considered if you’re dealing with a more severe infestation. You can make slug traps by using containers that are filled with beer or a solution based on yeast, which attracts slugs and drowns them. On the other hand, since commercial slug baits made of iron phosphate decompose into naturally occurring elements in the soil, they are both environmentally benign and effective.

The secret to controlling slugs in your cellar is to be consistent. Keeping an area dry and clean and conducting routine inspections can help ward off infestations in the future. You may successfully control and get rid of slugs and guarantee a tidy and pest-free cellar area by combining these techniques and exercising caution.

General information about slugs

Note that we are discussing land gastropods, which is important to understand how dangerous such a neighborhood can be. A temperature range of +15 to +19 degrees is ideal for them. Slugs prefer the warmth of the cellar over the outside, where they would freeze to death, even though it is colder there. They can also safely go into "hibernation" in a closed concrete room without worrying about freezing to ice over.

Practical! It is interesting to note that adults often die or go into suspended animation at below-freezing temperatures. However, nothing negative occurs to their clutches.

Slugs are hermaphrodites as well. In other words, they do not need to "create pairs" of different sexes in order to reproduce. As a result, they are able to spread quickly, and the problem of eliminating the "queen" remains unsolved.

Slugs are typically found in cellars:

  • forest or garden;
  • mesh;
  • from Southern Europe.

The latter kind is the most disagreeable visitor for gardeners and is highly prevalent nowadays. An adult mollusk’s length typically reaches 15 cm. It should be noted that the slug is toxic in addition to being gluttons, acting on the principle "what I don’t eat, I’ll bite." There is a chance of severe poisoning if a pet consumes it.

Any of these mollusks’ mucus provides an ideal habitat for bacterial growth. Thus, tomatoes will rot more quickly even if a slug just "walks" over them.

What it eats and when it is most active

Slugs devour nearly anything that comes into contact with their teeth, but they particularly enjoy grains, potatoes, cabbage, and tomatoes. The young shoots of grain crops are the most important delicacy. They only avoid contact with other spices, onions, parsley, and garlic. Slugs don’t respect cucumbers for some reason.

Slugs lay their eggs at night and search for food early in the morning. Notably, fresh "slugs" emerge in roughly two weeks. It is therefore advised to poison these "neighbors" multiple times. If not, the eggs that survived the initial events will develop into ferocious young.

Should you choose to do nothing, things can get worse very quickly. Of course, it is preferable to address the issue right away with traditional remedies and preventative measures rather than allowing it to reach this stage.

We explore efficient ways to get rid of these bothersome insects from your cellar area in our guide, "How to Get Rid of Slugs in the Cellar." Slugs can be an annoyance and a source of damage, particularly in moist areas like cellars. We look at doable tactics like caulking openings, lowering humidity, and employing organic discouragers like coffee grounds or diatomaceous earth. You can rid your cellar of slugs and keep your house or place of business pest-free and clean by following these easy steps.

How to get rid of slugs

It is important to remember that the cellar is meant to be used for food storage, so aggressive, chemical, and specialized preparations should only be used when no other option remains. It makes sense to begin with the easiest.

Scare away slugs

Let me state up front that this technique works best when there aren’t many slugs. The current individuals need to be apprehended and eliminated in any manner (burned, crushed, or released into the wild far from your site). Next, you have to build slug-proof barriers.

Practical! Place polyethylene on the floor at night and arrange all the products on the upper shelves to catch slugs. The mollusks will congregate beneath the polyethylene because the floor will be a humid and reasonably warm place. It will be sufficient to open it in the early morning and manually remove the pests.

Their abdomen is extremely sensitive and tender because they are mollusks. Thus, on a rough surface, the slug will never move. That’s why we want to make it. This can be accomplished with any finely divided material. For instance, you could use tiny bits of concrete or brick, coarse sand, or the remains of expanded clay. You can also use ash, mustard powder, and coarse salt. Mollusks on spruce needles are immobile. Pour all of this onto the aisles leading up to the produce and other product shelves. Pouring the composition at the cellar’s entrance is also worthwhile.

Additionally, you could try sprinkling parsley and garlic on the shelves (cut the cloves in half to make the odor repulsive to slugs more pronounced). Lavender can also help frighten off the obtrusive mollusks.

Another method is to use the liquid that is left over after boiling red hot pepper that has been crushed into a powder and lubricating the cellar’s drawers, shelves, and other surfaces. Slugs’ tender abdomens will burn from this composition.

Practical! Additionally, the smell of coffee grounds and ammonia solution (about two teaspoons per liter of water) is offensive to slugs.

However, barriers won’t help if there are already a lot of slugs and they have undoubtedly caused a lot of clutches.

Traps

In this instance, there are various choices:

  • Beer trap. As it turns out, slugs have a soft spot for beer, especially dark beer. Therefore, take any plastic container (you can cut a Coca-Cola bottle into two parts). Pour the intoxicating drink into it to the middle and install it in the center of the cellar. If the floor is earthen, it is even better to dig a jar in so that it is easier for slugs to get into it. When mollusks get inside, they will drown. After that, it is enough to throw out the lifeless bodies of the parasites and finish off the rest. Kefir works on the same principle.
  • Corn flour. Slugs also love it. To catch mollusks on flour, it is enough to pour it into any container and lay them on their side. Slugs cannot move normally on flour, so they will wait for your arrival the next morning.

Practical! Rotten tomatoes can also be placed in newspapers or wet rags that have been laid out.

These approaches, however, merely serve to divert the slugs from the real issue. They then need to be manually gathered and destroyed.

Dusting the cellar

Because of its gentleness, this method is not as risky. However, you must empty the cellar and inspect the walls, floor, and ceiling for cracks before beginning the treatment. If present, they need to be sealed. Next, make a chalk and ash mixture and apply it to the cellar’s entire surface. It’s critical that the mixture reaches the intended targets and any openings that slugs might exploit. Mollusks that come into contact with such powder will perish instantly. Thus, gathering and discarding the fallen’s bodies is all that’s left to do after a while.

Subsequently, the cellar is thoroughly cleaned. After applying an antiseptic, the surfaces need to be whitewashed. You cannot use the cellar again and bring everything back in until after this. If you don’t build barriers for slugs, they will come back to you.

Smoke bombs

This is a more drastic approach that is likewise forbidden in the event that the cellar is situated in a residential building’s basement. You can eradicate every pest in one fell swoop if the cellar is separate. To accomplish this, all you need to do is purchase a sulfur smoke bomb from any hardware store, or from vegetable and garden growers.

  • We close all the openings in the cellar.
  • We take out the food and equipment.
  • Place the smoke bomb on metal (or other fireproof material) and set it on fire.
  • Quickly leave the cellar and close the door.

Crucial! Inhaling sulfur vapors from the smoke bomb can result in a significant swelling of the throat. Thus, it is preferable to try to hold your breath and wear a mask over your mouth (or even better, put on a gas mask).

  • Forget about the cellar for 2 days (you cannot enter it).
  • Ventilate the room for 24 hours.
  • Carry out a thorough wet cleaning and ventilate again.
  • Collect the destroyed slugs and create barriers.

Practical! Notably, this treatment will also eliminate the pests’ clutches.

It is important to remember that smoke bombs are useful for getting rid of mold and mildew that has grown in the cellar as a result of condensation.

Chemical agents

The only thing left to do is launch a chemical assault on the slugs if all other attempts have failed. Insecticides are appropriate in this situation as they frequently assist summertime residents in getting rid of bothersome insects that ruin crops. In the store, you can ask for molluscicide. It’s chemistry, even though this poison isn’t that harmful. It’s one thing to use it outside, but you should exercise caution if using it indoors. As a result, you must remove everything from the storage.

The most well-liked among gardeners are "Metaldehyde," "Ulitsid," "Groza," and "Patrol." Nonetheless, since the majority of these products are meant to be used on open beds, you should carefully read the instructions and take note if it states that the medication is definitely not meant to be used in a closed space.

Ferramol is thought to be a more delicate, albeit pricey, product. It’s not too strong, so you can use it in the cellar.

Method Description
1. Salt Spread salt around areas where slugs are seen; it dehydrates them.
2. Beer traps Place containers filled with beer to attract and drown slugs.

There are a few successful ways you can try to get rid of slugs if you have them in your cellar. Make sure your cellar is dry and has adequate ventilation first. Because slugs prefer damp environments, lowering the humidity will help deter them.

Eliminating their food sources is another sensible strategy. Organic materials such as cardboard, damp wood, and old newspapers are attractive to slugs. Take these things out of your cellar to discourage them from coming in.

You can use yeast or beer solutions to set up traps for a more direct approach. Due to their attraction to the smell, slugs will crawl into containers containing these liquids and end up drowning. For ongoing efficacy, make sure to periodically inspect and replace these traps.

If you would rather use a natural deterrent, you might want to cover entry points and slug-prone areas with crushed eggshells or diatomaceous earth. Because of their sharp edges, these materials form a barrier that is challenging for slugs to get through.

Finally, you might need to seek advice from a pest control expert if the slug infestation continues after making these efforts. After evaluating the issue, they can suggest focused treatments that are both secure and efficient for the conditions in your cellar.

With the help of these techniques, you can efficiently control and minimize the slug population in your cellar, making it a more hygienic and welcoming area free of these bothersome vermin.
