Giant African Land Snail: 7 Health Problems & Fixes

If your Giant African land snail (such as Archachatina sp. and Achatina sp.) is hiding, not eating, or has a damaged shell, don’t wait. Most health problems in pet land snails come from low humidity, lack of calcium, or dirty substrate. Here are the 7 most common health issues in Giant African land snails and exactly how to fix them — without guesswork.

Improper handling, poor environment, and wrong diet are the main reasons snails get sick and stressed. Here is how to fix the 7 most common issues.

Quick Diagnostic Guide:

Improper Handling (GALS)

Giant African land snails have delicate bodies, and improper handling can lead to body damage. When handling them, it is important to support their entire body, including the shell, to avoid any stress or injury.

Both adults and children may harm the snail by improperly picking it up by its shell and forcibly removing it from a smooth surface, causing strain on the muscles that secure the shell. This may result in shell damage or injury to the snail’s internal organs.

The Fix:

The correct way to handle a giant land snail is to moisten the surface it is on, then use a moist hand to lift it softly and very slowly, supporting its head with a finger. Another way to hold them is to use a large cabbage leaf.

Environment Changes

Giant African land snails are sensitive to temperature and humidity levels. Depending on the species, their terrarium should have a temperature range of around 68 – 82°F (20 – 28°C) and relative humidity of 60-80%.

At low temperatures, the snail usually falls into a state of stupor (hibernation) and can die, while under the influence of direct sunlight or a hot temperature – it can almost “cook alive” in the terrarium.

If the environment is too dry, the snail’s shell can become dehydrated, leading to health problems.

The Fix:

Monitor your temperature and humidity. Do not allow it to fluctuate too much.

When the environment is unfavorable, snails will naturally retreat into their shells for safety. Don’t attempt to force the shell open as it will only cause additional stress to the snail. Instead, allow the snail to come out of its shell on its own by providing a moist environment and placing food nearby.

Baths

Avoid submerging Large African snails in water as they can’t breathe underwater and may drown.

The Fix:

Instead, give them a short, warm shower as a substitute for bathing, since they do enjoy moisture but it must be done with caution. The shower will mimic the rain in their natural habitat.

Do it once a month to keep them healthy.

Dirty Hands (Contaminations)

Many hobbyists also have cats and dogs in their homes. Of course, they periodically treat their hairy friends for fleas and other parasites.

Unfortunately, it is important to note that such treatments commonly used for dogs and cats can be highly toxic to Giant African land snails.

Almost the same can be said about hand creams, cleaning agents, and food residue (especially salt). Salt and household chemicals are the true enemies of these snails. When corrosive substances come into contact with the skin or internal organs of the mollusk, it releases a large amount of white foam.

The Fix:

Clean your hands before handling. Do not use sprays near snail tanks. It may leave burns on the snail’s delicate body or even has a lethal effect on them.

Incorrect Feeding

Giant African land snails are nature’s natural scavengers. Basically, they will eat anything they come across.

Therefore, pet owners often mistakenly believe they can feed them any food. This can lead to health problems if they give snails fatty, salty, or spicy food from their own meals. Children may be particularly prone to making this mistake.

The Fix:

Giant African land snails require a varied diet of fresh vegetables, fruits, and calcium supplements to maintain a healthy shell. For example, feeding them a diet that is too low in calcium can lead to shell thinning and softening.

Losing Its Shell

A snail falling out of its shell can occur due to severe damage or genetic factors. Bacteria, infections, and fungi can also cause this issue.

Unfortunately, in 99% of cases, it leads to the death of the snail.

Shell Diseases

Physical damage, fungal infections, contaminated substrate, too high or too low humidity/temperature, calcium imbalances, and vitamin deficiencies can cause shell problems for the Giant African land snails, including deformities and tissue changes.

To treat minor shell damage, gently clean the affected area with a soft toothbrush and a weak chamomile infusion. Never use milk or dairy products in the tank — it causes bacterial blooms and will kill your snail. Clean the entire terrarium, replace the substrate, and ensure proper ventilation..

Ensure proper ventilation and avoid over-moistening the soil. Use Sphagnum moss to check humidity levels (if it is green, the humidity is OK).

The Fix:

If you observe changes such as bumps, fragility, scaling, peeling, or gnawing, you need to check their environment and adjust the snail’s diet to include high-quality calcium sources like an eggshell.

Regular cleaning and using purified and aged water can prevent mold growth.

Health Issues

Giant African land snails are susceptible to a range of health problems, including:

1. Parasitic infections:

Snails can become infected with parasites such as nematodes, which can lead to serious health problems and even death.
A snail infected with worms becomes sluggish and loses weight, and some worms may even be visible on its body. If the owner does not take any action, the snail will die in most cases.

There are no proven, safe anti-parasitic treatments for pet snails. Forum myths suggest using pumpkin seeds or herbal infusions, but these do not work for gastropods and can cause digestive stress. If you suspect a severe parasitic infection, isolate the snail immediately to protect others. In most cases, supportive care (optimal humidity, clean substrate, and calcium) is the only safe approach while the snail’s immune system fights it off.

Steps to take for a parasitic-infected snail:

• Isolate the infected snail immediately from other snails.
• Inspect other mollusks for signs of worm infection.
• Clean the terrarium thoroughly and replace the substrate completely.

2. Infections (viruses and bacteria):

Treatment is highly controversial. Some breeders use extremely weak solutions of antibiotics (like penicillin), but incorrect dosing is fatal to invertebrates. Prevention is the only reliable method: clean the enclosure daily and wipe the shell periodically.

However, it is way easier to prevent infections than treat them. To prevent infection, the enclosure should be cleaned daily and the shell should be wiped periodically.

3. Internal Organ Dropping:

The causes of internal organ dropping in snails are unknown. Some people believe that it is because of overcooling, while others blame genetics or weak muscles due to lack of movement. What to do:

• If the dropping is not severe, try to help the snail retrieve its organs by gently putting them back in place.
• Ensure that the fallen organs do not dry out and that the mucus does not crack by keeping the snail moist.

Quick Summary

To avoid all of the above-mentioned problems, simple and systematic daily actions can help. These include:

• caring for the terrarium,
• cleaning it and replacing the soil in a timely manner;
• maintaining a balance of temperature and humidity;
• selecting proper food, having a balanced diet and avoiding salty, cured, and sweet foods; handling raw fruits and vegetables, monitoring food freshness.

That’s it. Keep the terrarium clean, watch for these 7 signs, and your snail will be fine.

FAQ

Q: How long do Giant African land snails live?
A: 5-10 years in captivity with proper care. Some species up to 12 years.

Q: Can a Giant African land snail survive a cracked shell?
A: Yes, if the crack doesn’t expose internal organs. Isolate the snail, increase calcium in its diet, and keep humidity above 80% to help the shell repair itself.

Q: Can snails live without their shell?
A: Unfortunately, no.

Q: How do I know if my Giant African land snail is sick?
A: Look for sluggish behavior, loss of appetite, sealing the shell for weeks, excessive white foam, or visible shell damage.

Q: What do I do if my snail is covered in white foam?
A: White foam is a defense mechanism against toxins. Immediately rinse the snail under clean, dechlorinated water. Check your substrate for salt, soap residue, or fertilizers.
