If you’ve been growing Alocasia in Nigeria, you’ve probably dealt with millipedes at some point.
These crawling creatures love our humid climate.
They show up in your pot, curl up when disturbed, and multiply faster than you’d expect.
I remember the first time I spotted millipedes in my Alocasia Polly’s pot in my Lagos apartment.
I panicked.
I thought they were killing my plant.
But here’s what I’ve learned after years of growing Alocasia in Nigeria: millipedes aren’t always the main problem.
Sometimes they’re just a symptom of other issues in your pot.
This guide covers everything about Alocasia care in Nigeria with a special focus on getting rid of millipedes naturally.
No harsh chemicals.
Just practical solutions that work in our Nigerian climate.
Understanding Millipedes in Your Alocasia Pot
What Are Millipedes Really Doing in There?
Millipedes are decomposers.
They feed on decaying organic matter in your soil.
When you see them in your Alocasia pot, it usually means there’s too much rotting material.
Maybe old leaves, decomposing roots, or organic matter breaking down too fast.
In Nigeria’s humid weather, especially during rainy season, organic matter decomposes quickly.
This creates a perfect feeding ground for millipedes.
Are Millipedes Harmful to Alocasia?
Here’s the truth most people don’t tell you.
Healthy millipedes rarely damage healthy plant roots.
They prefer dead and decaying material.
But when their population explodes, they might nibble on tender new roots or damaged tissue.
This can stress your Alocasia, especially younger plants.
I’ve seen Alocasia plants survive with a few millipedes in the pot.
But when you spot 10, 20, or more, that’s a problem.
It means your soil conditions need fixing.
Why Millipedes Love Nigerian Climate
Our weather is perfect for millipedes.
High humidity, warm temperatures, and frequent rainfall create ideal breeding conditions.
In Lagos, Port Harcourt, or Calabar, you’re dealing with 70-90% humidity most of the year.
Add poorly draining soil to the mix, and millipedes move in like they own the place.
Signs Your Alocasia Has a Millipede Problem
Visual Indicators
You’ll see millipedes curled up in the soil when you water.
They come to the surface when disturbed.
Sometimes you’ll notice them on the pot rim at night.
Check under the pot too—they hide in dark, moist spaces.
Plant Health Symptoms
If millipedes are causing real damage, your Alocasia might show these signs:
- Yellowing leaves despite proper care
- Stunted new growth
- Soft or mushy stems at the base
- Root damage visible when you check the roots
- General lack of vigor
But remember, these symptoms can also come from overwatering or root rot.
Don’t blame everything on the millipedes.
Soil Condition Warning Signs
When I lift the pot and the soil smells musty or sour, that’s a red flag.
Healthy soil smells earthy and fresh.
If your Alocasia soil stays wet for days after watering, you’ve created a millipede paradise.
The soil should dry out partially between waterings, even in humid Nigerian weather.
Natural Remedies for Millipedes in Alocasia Pots
Method 1: Potato Trap (My Personal Favorite)
This is the simplest method I’ve used with great success.
What you need:
- One medium Irish potato
- A knife
- Patience
How to do it:
Cut the potato in half.
Scoop out a small depression in the cut side.
Place it cut-side down on the soil surface in your Alocasia pot.
Leave it overnight.
Check in the morning.
You’ll find millipedes gathered under the potato, feeding on it.
Remove the potato with the millipedes and dispose of it.
Repeat for 3-5 nights until you see fewer millipedes.
This works because millipedes are attracted to the moisture and decomposing starch.
Method 2: Diatomaceous Earth (DE)
I discovered this method after talking to a friend who grows vegetables in Ibadan.
Diatomaceous earth is a natural powder made from fossilized algae.
You can find it in some agricultural stores in Nigeria, or order online.
How to use it:
Sprinkle a thin layer of food-grade DE on the soil surface.
When millipedes crawl over it, the microscopic sharp edges damage their exoskeleton.
They dehydrate and die.
Reapply after watering or rain, as it loses effectiveness when wet.
Safety note: Use food-grade DE only, especially if you have pets or children.
Method 3: Neem Oil Soil Drench
Neem is our Nigerian natural pesticide.
You can buy neem oil from markets or agricultural shops.
Recipe:
- 2 tablespoons neem oil
- 1 teaspoon mild liquid soap (helps it mix with water)
- 1 liter of water
Mix thoroughly and water your Alocasia with this solution.
The neem doesn’t kill millipedes instantly, but it makes the soil environment less attractive to them.
It also helps with other pests and has antifungal properties.
Use this once every 7-10 days for three weeks.
Method 4: Wood Ash Barrier
This is an old Nigerian gardening trick.
If you have access to wood ash from cooking fire or burnt wood, use it.
Application:
Sprinkle a thin line of wood ash around the base of your Alocasia stem.
You can also mix a small amount into the top inch of soil.
Millipedes dislike the alkalinity and texture of wood ash.
This creates a natural barrier.
Don’t overdo it though—too much ash can affect soil pH.
Method 5: Manual Removal During Repotting
Sometimes the best solution is starting fresh.
When millipede population is out of control, repotting is your best bet.
Step-by-step process:
Remove your Alocasia from the pot carefully.
Shake off the old soil gently.
Inspect the roots—trim any mushy or damaged parts with clean scissors.
Prepare fresh, well-draining soil (I’ll cover the best mix for Nigerian conditions below).
Clean the pot thoroughly with soapy water.
Rinse and dry completely.
Repot your Alocasia in the fresh soil.
This removes the millipedes’ food source and gives your plant a fresh start.
Preventing Millipedes: The Best Long-Term Solution
Perfect Soil Mix for Alocasia in Nigeria
Your soil mix determines whether millipedes become a recurring problem.
Heavy, water-retaining soil creates the perfect millipede habitat.
My proven soil recipe for Nigerian climate:
| Ingredient | Proportion | Purpose |
|---|---|---|
| Regular potting soil | 40% | Base structure, nutrients |
| Coarse river sand | 30% | Drainage, aeration |
| Perlite or pumice | 20% | Prevents compaction, improves drainage |
| Well-aged compost | 10% | Nutrients, but not too much organic matter |
This mix drains well even during Lagos rainy season.
It doesn’t stay soggy, which discourages millipedes.
You can find these materials in garden centers in major Nigerian cities.
If you can’t get perlite, increase the sand proportion to 50%.
Watering Strategy That Prevents Millipede Infestation
This is where most Nigerian growers go wrong.
We tend to overwater because we think our plants need constant moisture in the heat.
My watering approach for Alocasia in Nigeria:
Check the soil before watering.
Stick your finger 2 inches deep.
If it feels moist, wait another day or two.
When you water, water thoroughly until it drains from the bottom.
Then wait for the top 2 inches to dry before watering again.
In harmattan season (November-February), this might mean watering every 3-4 days.
During rainy season, you might only need to water once a week.
Indoor vs outdoor Alocasia watering differences:
Indoor plants in AC rooms dry faster.
Outdoor plants in shade during rainy season might need very little supplemental water.
Adjust based on your specific conditions.
Pot Selection and Drainage
I’ve killed more Alocasia plants with poor pot choices than any pest ever did.
Choose pots with:
- Multiple drainage holes (at least 4-5 for medium pots)
- Terracotta or unglazed ceramic for better air circulation
- Proper size—not too large for your plant
Oversized pots hold too much moisture.
The unused soil stays wet and attracts millipedes.
Drainage hack for Nigerian conditions:
Place a layer of broken pottery pieces or stones at the bottom before adding soil.
This ensures water flows out freely.
I learned this from my grandmother who grew plants in Enugu.
It works perfectly.
Light and Air Circulation
Good air circulation discourages millipedes.
They prefer still, humid conditions.
For indoor Alocasia:
- Place near a window with bright, indirect light
- Run a fan occasionally to improve air movement
- Avoid corners where air becomes stagnant
For outdoor Alocasia:
- Choose spots with morning sun, afternoon shade
- Ensure they’re not crowded by other plants
- Consider raised stands to improve air circulation under pots
In Lagos humidity, air movement makes a huge difference.
Understanding Alocasia Care in Nigeria
Light Requirements
Alocasia needs bright, indirect light to thrive.
Direct Nigerian sun, especially midday sun, will scorch those beautiful leaves.
Indoor placement:
- East-facing windows are perfect
- South-facing windows with sheer curtains
- 3-5 feet from west-facing windows
Outdoor placement:
- Under trees with dappled shade
- North-facing walls
- Covered porches or verandas
I keep my Alocasia Zebrina on my balcony in Lagos.
It gets morning sun until about 10 AM, then shade for the rest of the day.
Perfect growth with dark green leaves.
Temperature and Humidity
Nigerian climate is actually ideal for Alocasia.
These plants love warmth and humidity.
Ideal conditions:
- Temperature: 18-27°C (we’re usually in this range)
- Humidity: 60-80% (Lagos, PH, Calabar naturally provide this)
Harmattan season challenges:
Humidity drops during harmattan.
Your Alocasia might show crispy leaf edges.
Solutions:
- Mist leaves in the morning
- Group plants together
- Place pots on pebble trays with water
- Move plants to bathrooms or kitchens temporarily
Fertilizing Alocasia in Nigerian Conditions
Don’t overfertilize thinking it’ll help your plant grow faster.
Excess organic fertilizer increases decomposition in soil.
This attracts more millipedes.
My fertilizing schedule:
Use balanced liquid fertilizer (NPK 10-10-10 or 20-20-20).
Dilute to half the recommended strength.
Apply every 3-4 weeks during rainy season (active growing period).
Reduce to once every 6-8 weeks during harmattan.
Organic options:
Well-aged compost tea works well.
Avoid fresh manure or uncomposted materials directly in pots.
They attract millipedes and other decomposers.
Common Mistakes That Invite Millipedes
Mistake 1: Using Garden Soil
Never use garden soil directly in pots for Alocasia.
Nigerian garden soil is often heavy clay-based.
It retains too much water.
Millipedes love it.
Always use properly mixed potting soil with good drainage components.
Mistake 2: Bottom Watering Gone Wrong
Some people leave pots sitting in water-filled saucers.
They think it provides humidity.
This creates a constantly moist environment at the bottom.
Perfect for millipedes to multiply.
Empty saucers 30 minutes after watering.
Mistake 3: Mulching Indoor Pots
Mulch is great for outdoor gardens.
But in Alocasia pots, especially indoors, it’s trouble.
Organic mulch like wood chips or bark decomposes.
This feeds millipedes.
Keep the soil surface clear in pots.
Mistake 4: Ignoring Dead Leaves
When Alocasia leaves die (it’s natural), remove them promptly.
Don’t let them fall into the pot and decompose there.
Each dead leaf is a millipede buffet.
Cut them at the base and dispose properly.
When to Worry vs When to Relax
Normal Millipede Presence
Seeing 1-3 millipedes in a large Alocasia pot isn’t a crisis.
If your plant looks healthy, don’t panic.
Just monitor the situation.
Try the potato trap once or twice to reduce numbers.
Red Alert Situations
Take immediate action when:
- You see 10+ millipedes in one pot
- Millipedes are visible on the plant stem or leaves
- Your Alocasia shows declining health
- Soil smells foul
- Roots appear damaged during inspection
This means your soil ecosystem is out of balance.
Time for repotting and fresh soil.
Other Pests to Watch For in Nigerian Alocasia
While dealing with millipedes, watch for these common Nigerian plant pests:
Spider mites:
- Tiny red or brown dots on undersides of leaves
- Fine webbing between leaves and stems
- Treat with neem oil spray or insecticidal soap
Mealybugs:
- White cottony masses on stems and leaf joints
- Remove manually with alcohol-soaked cotton swabs
- Follow up with neem oil treatment
Fungus gnats:
- Small flying insects around soil
- Larvae feed on organic matter like millipedes do
- Reduce watering frequency
- Use sticky traps for adults
Scale insects:
- Brown bumps on stems and leaves
- Hard to remove once established
- Scrape off manually or use horticultural oil

The Reality of Growing Alocasia in Nigeria
Let me be honest with you.
Alocasia isn’t the easiest plant for beginners.
But it’s also not impossibly difficult.
In Nigerian conditions, you have natural advantages—warmth and humidity.
Your main challenges are managing water and preventing pest buildup.
I’ve grown Alocasia for over five years now.
Some plants thrived immediately.
Others took time and adjustments.
I’ve lost plants to root rot, spider mites, and yes, once to a severe millipede infestation.
Each failure taught me something.
The key is observation.
Check your plants regularly.
Notice changes early.
Adjust care based on what you see, not just what a generic guide says.
Your Lagos apartment has different conditions than a house in Kano.
Your indoor environment differs from your neighbor’s.
Learn your specific space and adapt.
Final Thoughts on Millipede Management
Natural remedies work, but they require consistency.
You won’t eliminate millipedes overnight.
Be patient with the process.
More importantly, focus on prevention.
Good soil, proper watering, and adequate drainage solve 90% of millipede problems.
When you create an environment that’s healthy for your Alocasia, it’s naturally less attractive to millipedes.
Your plant will have strong roots to resist any minor pest damage.
Remember, millipedes are part of the natural soil ecosystem.
They’re not inherently evil.
In outdoor gardens, they’re actually helpful decomposers.
It’s only when they overpopulate in confined pot spaces that they become problematic.
Start with the fundamentals of Alocasia care in Nigeria—right soil, right watering, right light.
The millipede problem often resolves itself when you get these basics right.
If you’re currently dealing with an infestation, choose one or two natural methods from this guide.
Apply them consistently for 2-3 weeks.
Monitor your plant’s response.
And please, don’t give up on your Alocasia because of millipedes.
These plants are worth the effort.
That dramatic foliage, those stunning leaves—nothing quite compares.
You’ve got this!
Frequently Asked Questions
1. How do I know if millipedes are eating my Alocasia roots?
Millipedes typically feed on decaying organic matter, not healthy roots. If your Alocasia shows stunted growth, yellowing leaves, or becomes unstable in the pot despite proper care, gently remove it and inspect the roots. Damaged roots will appear brown, mushy, or have visible bite marks. However, these symptoms more commonly indicate root rot from overwatering rather than millipede damage. If you find damaged roots with visible millipedes present, repot immediately in fresh, well-draining soil.
2. Can I use insecticide spray for millipedes in my Alocasia pot?
While chemical insecticides will kill millipedes, I don’t recommend them for indoor pots in Nigeria. These chemicals can harm your plant, contaminate indoor air, and aren’t necessary for millipede control. Natural methods like potato traps, diatomaceous earth, and neem oil work effectively without toxic side effects. If the infestation is severe, complete repotting with fresh soil is safer and more effective than chemical treatment. Save harsh chemicals for outdoor pest emergencies only.
3. Why do millipedes keep coming back to my Alocasia pot even after I remove them?
Recurring millipede problems indicate underlying soil issues. Your soil likely retains too much moisture, contains excessive organic matter, or lacks proper drainage. Millipedes don’t randomly infest pots—they’re attracted to specific conditions. To permanently solve the problem, you must improve soil drainage, adjust watering frequency, and ensure the pot has adequate drainage holes. Simply removing millipedes without fixing these root causes means they’ll return. Consider repotting with a proper soil mix designed for Nigerian humidity levels.
4. Is it safe to use wood ash on Alocasia if I live in Lagos where water is slightly acidic?
Yes, using moderate amounts of wood ash is safe and can actually benefit your Alocasia in Lagos. A light sprinkling of wood ash (about 1-2 tablespoons for a medium pot) won’t drastically change soil pH, especially with our frequent watering and natural rainfall that buffers pH changes. Wood ash provides potassium and creates an inhospitable environment for millipedes. Just don’t use it heavily or frequently—once every 2-3 months is sufficient. If you’re concerned, test your soil pH with a simple testing kit available in agricultural stores.
5. My Alocasia is outdoors in my compound; will millipedes harm it more than indoor plants?
Outdoor Alocasia plants typically handle millipede presence better than indoor plants. Outdoor environments have natural predators (birds, lizards, other insects) that control millipede populations. Rain also flushes through soil more effectively outdoors, preventing the buildup of decomposing matter that attracts millipedes. However, outdoor plants face more millipede exposure during Nigeria’s rainy season. Ensure your outdoor pots have excellent drainage, use pot feet or stands to elevate them, and avoid letting water pool around the base. Regular monitoring is key.
6. Can I use salt water to kill millipedes without harming my Alocasia?
Never use salt water on your Alocasia. While salt kills millipedes, it’s extremely harmful to plants. Salt damages roots, affects water absorption, and builds up in soil over time, creating long-term problems. Many plants have died from well-meaning owners using salt solutions. Stick to plant-safe methods like neem oil, diatomaceous earth, or manual removal. If you’re desperate for a quick solution, remove the plant from the pot, manually remove visible millipedes, and repot in fresh soil—much safer than risking salt damage.
7. How often should I repot my Alocasia in Nigerian climate to prevent millipede buildup?
Repot your Alocasia every 12-18 months in Nigerian conditions, regardless of millipede issues. Our humid climate breaks down soil components faster than in drier regions, causing compaction and reducing drainage over time. Annual repotting refreshes the soil, improves drainage, removes accumulated salts, and naturally eliminates any developing millipede populations. Choose the start of rainy season (March-April) for repotting so your plant has optimal growing conditions to recover. If you notice severe millipede infestation between scheduled repotting, repot immediately regardless of timing.
8. Do all Alocasia varieties attract millipedes equally in Nigeria?
All Alocasia varieties can experience millipede issues, but susceptibility depends more on care practices than variety. Larger varieties like Alocasia Macrorrhiza in bigger pots with more soil volume may harbor larger millipede populations simply due to space. Smaller varieties like Alocasia Polly in compact pots dry out faster and provide less habitat. However, the real determining factor is your soil quality and watering habits. I’ve successfully grown Alocasia Zebrina, Polly, and Black Velvet in Lagos without millipede problems by maintaining proper drainage and watering schedules. Focus on care rather than avoiding specific varieties.
