How to Care for Mystrium camillae | The Dracula Ant Guide for Experts
Updated: 3 days ago
Mystrium camillae, the Dracula ant, is one of the most fascinating ants in the world. Its jaws snap shut faster than any other animal movement ever measured, and its adults sip fluid from their own larvae.
Dracula ants are rare in the hobby, shy and secretive, and a real prize for an experienced keeper. This guide explains Mystrium camillae care step by step, from the day your parcel arrives.
We have kept ants since 1997. Everything here comes from our own colonies and the care rules we use every single day.

Meet the Dracula Ant
In the wild, Mystrium camillae lives hidden in the leaf litter and soil of tropical forests, under rotting wood and in dry twigs. It is a specialist hunter of centipedes and other small creatures.
Its jaws work like a finger snap. The ant presses the tips of its jaws together until one slides past the other, and it shoots forward at up to 90 metres per second. Scientists think it is the fastest animal movement ever recorded.
The name comes from the way the colony shares food. Adults make a tiny hole in a larva's skin and drink a little of its fluid, called haemolymph. The larva is not harmed, and works like the colony's food store.
Smaller workers mostly stay home and care for the brood, while bigger workers go out to hunt. Young colonies are very shy, and they become easier to see as they grow.
When Your Ants Arrive
The most important step: leave the parcel completely unopened, exactly as it arrived, at room temperature for 5 hours. The ants must adjust to your home's temperature slowly, because abrupt temperature changes make ants seriously unwell.
After the 5 hours, check the queen is safe and sound. Then leave the colony in its original packaging, with the test tube still in its tin foil and wrapping.
Put it somewhere quiet and still, away from daily household activity. Normal daylight is fine, but never direct sunlight.
Give the colony 4 to 5 days of complete rest. The ants were fed before dispatch, so they need nothing from you. Use this time to set up and water the nest. 👉 Our step-by-step ant farm setup guide shows you exactly how.
Still workers or a motionless queen after delivery are almost always delivery stress. Look at the queen's antennae: moving antennae mean she is fine. Almost all recover within 4 to 5 days.
Life in the Test Tube
Start with a colony, never a lone queen. Choose at least 10 workers with eggs, larvae or pupae laid inside that colony: the brood is your proof of a fertile queen. The more workers, the better your chance of success.
Keep the colony in its test tube until it has at least 10 workers. Moved earlier, the workers often abandon the queen in the bigger space, and the colony can fail.
Dracula ants need warmth even in the test tube. If your room is cool, warm the tube with a heating cable at the cotton stopper end only. Never lay a test tube on a heat mat.
Don't worry if you rarely see the ants. They are shy by nature, and a quiet, dark tube is exactly what they want.
Moving Into the Ant Farm
When the colony is big enough, connect the test tube to the nest with the delivery tin foil still on. Leave it like that for 14 days.
Then slide the foil back about 1mm every day, until the tube is fully exposed to daylight. Bit by bit, the tube becomes the bright spot and the dark nest becomes the safe home.
If the ants haven't moved 2 days after the tube is fully exposed, wrap the foil back on, wait another fortnight and repeat the whole process. Moving in happens on the ants' own time: anywhere from a couple of days to 6 months.
Once the colony has moved, leave the old test tube connected for at least another 14 days. Ants sometimes leave a little brood behind.
The red filter and black cover stay on the nest all the time, so it is pitch dark inside. You can lift the black cover once a day for 2 to 3 minutes, ideally at night, and take the red filter off once a week for 2 to 3 minutes.
Take colony photos at most once a month. A shy species like this one needs as little disturbance as possible.
The Best Ant Farm for Dracula Ants
Dracula ants are small and live in small colonies, so a compact nest suits them best. In a big nest you would hardly ever see them. Their home must be well made, escape-proof and easy to keep warm and humid.
👉 Our top pick is the A7 Plus ant farm kit. Its small nest suits this species, and its pre-installed digital meter shows the temperature and humidity at a glance, which matters a lot for a tropical ant.
Place the ant farm in normal daylight, never direct sunlight: the sun can overheat a nest within minutes. Avoid windows, radiators and heaters, vibrating surfaces, speakers and TVs, and rooms with strong smells such as the kitchen.
Temperature and Heating
Mystrium camillae comes from tropical forest floors, warm but shaded. Keep the nest at 21 to 26°C every day of the year. Most UK homes drop below that for much of the year.
👉 The Advanced Heating System Small 4W holds the nest steady with its digital thermostat. Set it to about 24°C, the middle of their range.
The heat mat goes under one quarter of the nest only, on the side opposite the watering area. The ants can then pick the spot they like best. Never heat the whole nest.
Warm the outworld too, because a big gap between nest and outworld confuses the ants. Aim for at least 21°C overnight, rising to about 26°C by day, ideally matching the nest or a degree or two cooler.
Water and Humidity
Leaf-litter ants like moisture. Keep the nest humidity at 60 to 80%. Use distilled or purified water only. Never use tap water, rainwater or bottled mineral water, even boiled: they cause mould and fungus, which is deadly for ants.
Water the nest with the pipette provided. Pour slowly, a few drops at a time, through the watering hole. Stop as soon as 1 or 2 drops appear inside the nest. That is how you know it is done correctly.
Warm nests dry out faster, so check the meter often. Water about once a week, a little more in summer and a little less in winter, and always as soon as the nest humidity drops below 60%.
Never water the outworld. Keep it at about 50% humidity, like an average UK home. A watering test tube in the outworld gives the workers a safe drink.
Feeding Your Dracula Ant Colony
Dracula ants are true hunters, and live prey is their only real food. They will not thrive on jelly or honey. Even a young colony needs live prey, sized so the small workers can overpower it.
🥩 In the wild they hunt centipedes. In an ant farm, give baby crickets, flightless fruit flies or tiny cockroach nymphs, twice a week, in the outworld only. Small centipedes are ideal when a reputable supplier has them.
Give the prey alive, because hunting is how these ants feed. Never scald live prey for Dracula ants. Remove any uneaten prey and the remains after 2 days to stop mould.
🍯 Sugars are not a key food for Dracula ants, and many colonies ignore them. If you like, try a tiny drop of our 👉 organic ant honey or 👉 Ant Nectar now and then, and remove it after 2 days. Live prey is what really matters.
Keep Mites Out of Your Colony
Blood-sucking mites are one of the biggest dangers for any ant colony, and they are not rare. Live food is the main risk for a hunter: in our experience about half of the live food sold in pet shops or online carries mites.
Mites also arrive with bird seed from local shops and with dried mealworms, which are useless as ant food anyway. Buy live prey only from established, reputable suppliers, and check it for mites before it goes in. Never collect centipedes outdoors.
At Best Ants UK we clean our foods in several ways before dispatch, check every colony twice a month, and check each colony again before it leaves us.
Now and then, look at your queen with a magnifying glass. Tiny white or reddish specks on her joints and legs, together with ants dying fast, are a warning sign of blood-sucking mites.
Stopping Escapes
Small workers fit through small gaps, so escape prevention is a must. Paint a band of 👉 PTFE Fluon escape barrier around the top inner edge of the outworld lid. The ants slip off it and can't climb out.
PTFE wears off as the ants keep testing the same spots. For a small colony of up to about 100 ants, reapply it roughly every 4 weeks. For 300 to 500 ants or more, reapply it about every 2 weeks.
Never shake the bottle, because it foams. Roll it gently in your hands instead. Dracula ants have a small sting, so never handle them and always use long tweezers in the outworld.
Winter Care
Dracula ants have no winter rest. They come from a climate that stays warm all year, so keep the nest at 21 to 26°C through every UK winter.
Cold doesn't kill a colony at once. The ants get sick and die over the following days, so never let them cool down. Never put ants in a fridge, shed or garage, and avoid any abrupt temperature change.
Kept warm, the colony stays active, so keep giving live prey twice a week in winter. If the ants eat less, simply give less.
Can I Release My Dracula Ants?
No. Dracula ants are tropical and could never survive outside in the UK. If you ever can't keep your colony any more, 👉 visit our ant adoption page and let us know. We'll see whether we can take it in.
Frequently Asked Questions | FAQ
Why is Mystrium camillae called the Dracula ant?
Because the adults drink a little blood-like fluid, called haemolymph, from their own larvae. It sounds scary, but the larvae are not harmed. It is how the colony shares food.
Are Dracula ants good for beginners?
No. Mystrium camillae is an expert species. The colony is shy, needs steady tropical warmth and live prey, and is rarely seen. For a first colony, Lasius niger or Messor barbarus is a far better start.
What do Dracula ants eat?
Live prey. In the wild they hunt centipedes. In an ant farm, give small live crickets, flightless fruit flies or tiny cockroach nymphs, sized to the workers, and small centipedes when you can get them from a reputable supplier.
What temperature do Mystrium camillae need?
Keep the nest at 21 to 26°C all year. In most UK homes that means an Advanced Heating System set to about 24°C under one quarter of the nest.
How many workers before moving Dracula ants into a nest?
At least 10 workers. Moved earlier, the workers often abandon the queen in the bigger space, which can lead to colony failure.
Do Dracula ants sting?
They have a small sting. Never handle them, keep the lid closed and always use long tweezers when you feed or clean the outworld.
Do Dracula ants hibernate?
No. They come from the tropics and have no winter rest. Keep them warm all year and avoid any abrupt temperature change.
