How to Get Slugs and Snails Out of Your Vivarium: Preventing and Managing Infestations in the UK
Keeping a vivarium in optimal condition can be a fulfilling experience, especially when it houses thriving reptiles, amphibians, or plants. However, one problem that frequently troubles vivarium owners, especially in the UK, is the uninvited presence of slugs and snails. These pests can cause significant harm by consuming plant material, disturbing your animals, and contaminating the enclosure. If you’ve noticed an uptick in these slimy invaders or are looking to prevent an infestation, this article is your comprehensive guide on how to remove and prevent slugs and snails from your vivarium.
Why Are Slugs and Snails a Problem in Vivariums?
Slugs and snails thrive in the same humid environments that are ideal for many reptiles, amphibians, and tropical plants, making vivariums a perfect breeding ground for them. Their presence can lead to several issues:
1. Plant Damage: Slugs and snails feast on plant matter, which can result in damaged or even dead plants. For those keeping planted vivariums, this can be particularly troublesome.
2. Fouling Water Sources: These creatures often leave behind a trail of mucus and faecal matter, which can contaminate the water bowls or other water features in the enclosure.
3. Disrupting Animals: Some small reptiles or amphibians may be stressed by the presence of slugs or snails, especially if these pests invade their shelters or feeding areas.
4. Spreading Disease: Snails and slugs can be carriers of harmful parasites like lungworm, which can pose a risk to animals within the vivarium.
Understanding these risks is the first step toward prevention and management. Let’s explore how you can remove slugs and snails effectively and prevent future infestations.
How Do Slugs and Snails Get Into a Vivarium?
Before discussing removal methods, it’s important to know how slugs and snails may have entered your vivarium in the first place. These pests often make their way into your enclosure through:
Substrate Contamination: Many vivarium owners purchase substrate from local garden centres or online stores. Unfortunately, these sources may harbour snail or slug eggs that hatch once in the warm, humid environment of your vivarium.
Unclean Decorations: Whether you’re using wood, rocks, or plants to decorate your vivarium, these materials may come with hidden eggs or larvae attached.
Openings in the Enclosure: Slugs and snails are capable of squeezing through incredibly tight spaces. If your vivarium has even the smallest gap, they can find their way inside.
Now that we know how these pests get in, let’s delve into practical methods of removing them from your vivarium.
How to Remove Slugs and Snails from Your Vivarium
If you already have an infestation, it’s essential to remove the slugs and snails without using harmful chemicals that could endanger your animals or plants. Here are some methods that are both effective and safe for vivarium environments.
1. Manual Removal
The simplest way to reduce the slug and snail population in your vivarium is to remove them manually. This method is straightforward but requires patience and persistence.
Night Checks: Slugs and snails are primarily nocturnal, so the best time to catch them in the act is after dark. Use a torch to inspect your vivarium for these creatures.
Use Gloves or Tweezers: To avoid touching the slimy pests directly, wear gloves or use tweezers to remove them. Make sure to check all corners of the vivarium, including under plants and decorations.
2. Natural Predators
Introducing a natural predator into your vivarium can be an effective way of controlling a slug or snail problem. However, this option depends on the type of animals you already house.
Carnivorous Snails: Certain snail species, like Rumina decollata, feed on other snails and could be a viable option for controlling smaller snail populations without harming your plants or animals.
Nematodes: In a controlled vivarium environment, beneficial nematodes (such as Phasmarhabditis hermaphrodita) can be used to target slugs without impacting other creatures.
Be sure to research the compatibility of any predator with the species in your vivarium before introducing them.
3. Traps and Lures
Creating simple traps can also help reduce the slug and snail population over time.
Beer Traps: Slugs and snails are attracted to the yeast in beer. Place a shallow dish filled with beer inside your vivarium. The pests will be drawn to it, fall in, and drown. Be sure to place the trap where your animals can’t access it.
Cucumber or Lettuce Traps: Slugs and snails love cucumbers and lettuce. Place slices in various spots around the vivarium as bait. After a few hours, simply remove the slices along with the pests clinging to them.
4. Barrier Methods
You can create barriers that slugs and snails find difficult to cross.
Copper Tape: One effective and popular method is using copper tape. Slugs and snails avoid copper because it gives them a mild electric shock when they attempt to cross it. Apply the tape around the base of your plants or the edges of your vivarium.
Diatomaceous Earth: This is a natural substance that is safe for most vivarium inhabitants but harmful to slugs and snails. Diatomaceous earth consists of fossilised algae that is sharp to soft-bodied creatures, causing dehydration when they attempt to cross it.
How to Prevent Slugs and Snails from Entering Your Vivarium
Once you’ve successfully dealt with the infestation, it’s crucial to implement preventive measures to ensure they don’t return. Prevention is often easier and less stressful than dealing with an infestation, so take the following steps:
1. Sterilise New Substrate and Decorations
As mentioned earlier, slugs and snails often enter vivariums through contaminated substrate or decorations. Sterilising these materials before introducing them into your vivarium can reduce the chances of an infestation.
Bake the Substrate: Place soil or other substrate materials on a baking sheet and bake it in the oven at 180°C (350°F) for about 30 minutes. This will kill any eggs, larvae, or pests.
Boil or Freeze Decorations: For rocks, wood, or other non-flammable decorations, either boil them in water for 10–15 minutes or freeze them overnight to kill any hidden pests.
2. Maintain Cleanliness
Regular cleaning of your vivarium can prevent pests from establishing a foothold.
Remove Food Waste Promptly: Leftover food, especially fruits and vegetables, can attract slugs and snails. Be diligent in removing uneaten food within a few hours.
Spot Clean the Substrate: Periodically remove sections of the substrate and replace it with fresh, sterilised material. This prevents the buildup of organic material that can attract pests.
3. Inspect New Plants Thoroughly
If you’re adding new plants to your vivarium, inspect them closely for any signs of snail or slug eggs.
Soak Plant Roots: Before placing new plants in the vivarium, soak the roots in a solution of water and potassium permanganate (a mild disinfectant) for about 10 minutes. This will kill any eggs or pests hiding in the soil.
Quarantine New Plants: Keep new plants in a separate enclosure for a week or two to monitor for any signs of pests before introducing them to your main vivarium.
4. Seal Any Gaps
If you suspect slugs and snails are entering your vivarium from outside, inspect the enclosure for any gaps, however small. Use silicone or other appropriate sealants to close any openings. Keep in mind that slugs and snails can squeeze through very tight spaces, so even minor cracks should be addressed.
Conclusion
Keeping slugs and snails out of your vivarium, or dealing with an existing infestation, requires a combination of manual removal, natural deterrents, and preventive measures. By regularly inspecting and cleaning your vivarium, sterilising new materials, and creating barriers, you can prevent these pests from taking over your carefully curated environment.
Remember, the key to success is persistence. Even if you manage to remove all visible slugs and snails, their eggs may still be present, meaning they could return. Regular vigilance will help you stay ahead of the problem, ensuring a healthy and balanced ecosystem within your vivarium.
