Snail farming (heliciculture) is a lucrative and low-maintenance agribusiness with high returns on investment (ROI). Snails are in high demand due to their nutritional value, use in cosmetics, and medicinal benefits. Starting a snail farm requires minimal capital, space, and expertise, making it ideal for beginners.
This guide covers:
- Why snail farming is profitable
- Choosing the right snail species
- Setting up a DIY snail farm (indoor/outdoor)
- Feeding and maintenance
- Breeding and growth management
- Harvesting and marketing
- Cost analysis and ROI

Why Snail Farming is Profitable
- High Demand, Low Supply – Snails are consumed worldwide, especially in Europe, Asia, and Africa. Local farmers often can’t meet demand.
- Low Startup Cost – Unlike poultry or fish farming, snails require minimal investment.
- Fast Reproduction – Snails lay 50-400 eggs per cycle, ensuring quick stock growth.
- Low Maintenance – They don’t need daily feeding or expensive housing.
- Multiple Revenue Streams – Sell snails for food, slime for cosmetics, or eggs for breeding.
Choosing the Right Snail Species
Not all snails are edible or profitable. The best species for farming include:
1. Achatina Fulica (Giant African Land Snail)
- Fast growth (reach market size in 10-12 months).
- High reproduction rate.
- Adaptable to different climates.
2. Achatina Achatina (Tiger Snail)
- Larger and more valuable than Fulica.
- Slower growth (12-18 months).
- High demand in export markets.
3. Archachatina Marginata (Big Black Snail)
- Premium price due to size and taste.
- Slower reproduction but highly profitable.
Pro Tip: Start with Achatina Fulica for beginners due to its hardiness and fast breeding.
DIY Snail Farm Setup (Step-by-Step)
1. Selecting a Farming System
You can raise snails in:
- Outdoor Pens – Best for large-scale farming.
- Greenhouses/Polytunnels – Protects from extreme weather.
- Plastic Containers/Wooden Boxes – Ideal for small-scale or urban farming.
2. Housing (Snailery Construction)
Option A: Outdoor Pen (Cheapest & Most Natural)
- Materials Needed:
- Wooden planks or PVC pipes (for frame).
- Fine mesh or netting (to prevent escape).
- Shade cloth (snails need 70-90% humidity).
- Soil (loamy, not sandy or clayey).
- Steps:
- Clear a shaded area (under trees is ideal).
- Build a raised pen (1m x 1m x 0.5m).
- Cover with mesh to keep out predators (rats, birds).
- Add moist soil mixed with limestone (for calcium).
Option B: Plastic Containers (For Urban Farmers)
- Materials Needed:
- Large plastic bins (with lid).
- Drill (for ventilation holes).
- Coconut fiber/soil substrate.
- Spray bottle (for humidity).
- Steps:
- Drill small holes (5mm) for air.
- Fill with 4-6 inches of damp soil.
- Add hiding spots (leaf litter, broken pots).
- Mist daily to maintain humidity.
3. Soil Preparation
- Use loamy soil (holds moisture but drains well).
- Avoid sandy or clay soil.
- Sterilize soil (bake or treat with lime) to kill pests.
- Maintain pH of 7-8 (add crushed eggshells for calcium).
4. Temperature & Humidity Control
- Ideal Temp: 25-30°C (77-86°F).
- Humidity: 70-90% (spray water 2x daily).
- Avoid direct sunlight (snails can dry out and die).
Feeding & Nutrition
Snails are herbivores but need a balanced diet for fast growth.
Best Foods for Snails
✔ Leafy Greens: Cabbage, lettuce, spinach.
✔ Fruits: Bananas, apples, watermelon.
✔ Vegetables: Cucumber, carrots, pumpkin.
✔ Calcium Sources: Eggshells, oyster shells, bone meal (for shell growth).
Foods to Avoid
✖ Salty foods
✖ Citrus (too acidic)
✖ Processed foods
Feeding Schedule:
- Feed once daily (evenings).
- Remove uneaten food to prevent mold.
Breeding & Growth Management
1. Selecting Breeders
- Choose healthy, active snails (at least 6 months old).
- Avoid snails with cracked shells.
2. Mating & Egg Laying
- Snails are hermaphrodites (both male and female).
- After mating, they lay eggs in soil (about 5cm deep).
- Eggs hatch in 2-4 weeks depending on temperature.
3. Caring for Hatchlings
- Keep baby snails in a separate container.
- Feed finely crushed leafy greens.
- Ensure high humidity (90%).
Harvesting & Marketing
When to Harvest
- Achatina Fulica: 10-12 months.
- Achatina Achatina: 12-18 months.
- Harvest when shells are fully hardened.
How to Harvest
- Fast snails for 24 hours (to empty their guts).
- Wash gently in clean water.
- Package live snails in ventilated boxes for sale.
Where to Sell (High-Profit Markets)
- Local Restaurants (African, French, Asian cuisines).
- Cosmetics Companies (for snail slime).
- Online (Facebook, eBay, Jiji).
- Export (Europe pays $5-$20/kg).
Cost Analysis & ROI
Startup Costs (Small-Scale Farm – 100 Snails)
| Item | Cost ($) |
|---|---|
| Snail Stock (100) | $50 |
| Housing (Plastic Bins) | $20 |
| Soil & Substrate | $10 |
| Feed (Monthly) | $15 |
| Miscellaneous | $10 |
| Total | $105 |
Revenue Projection (After 12 Months)
- Each snail lays 100+ eggs/year.
- Survival rate: 70% → 70 new snails per breeder.
- 100 breeders → 7,000 snails in a year.
- Selling price: $2-$5 per snail (depending on size).
- Potential Revenue: $14,000 – $35,000/year.
ROI: 10,000%+ (if properly managed).
Common Mistakes to Avoid
- Poor Soil Quality – Leads to slow growth and disease.
- Overcrowding – Causes stress and cannibalism.
- Low Humidity – Snails hibernate instead of growing.
- Wrong Feeding – Lack of calcium weakens shells.
Here are some frequently asked questions (FAQs) about snails:
General Questions
- What is a snail?
- A snail is a small, slow-moving mollusk with a coiled shell, belonging to the class Gastropoda. They can be found on land, in freshwater, and in marine environments.
- Are snails insects?
- No, snails are mollusks, not insects. They are related to slugs, clams, and octopuses.
- How long do snails live?
- Lifespan varies by species. Garden snails live 2-5 years, while some larger species (like the Roman snail) can live 10-15 years in captivity.
- Do snails have brains?
- Yes, but their brains are very simple. They have a decentralized nervous system with clusters of nerve cells (ganglia).
Anatomy & Biology
- Why do snails have shells?
- The shell protects them from predators and harsh environmental conditions (like dryness). It also helps retain moisture.
- Can snails leave their shells?
- No, a snail’s shell is permanently attached to its body. If the shell breaks, the snail may die.
- Do snails have teeth?
- Yes! Snails have a radula, a tongue-like organ with thousands of tiny teeth used for scraping food.
- How do snails move?
- They secrete mucus to glide on their muscular foot, reducing friction and protecting their bodies from rough surfaces.
Behavior & Habitat
- Are snails nocturnal?
- Many land snails are active at night or during damp weather to avoid drying out in the sun.
- Why do snails leave a slimy trail?
