Key Takeaways
Ant keeping is a slow-burning hobby, and the first year is the making of your colony. After nearly thirty years of doing this, here is the honest shape of it.
• Months 1 to 2 | Founding: a lone queen in a test tube, no food, no fuss. Leave her alone and let her raise her first workers.
• Months 3 to 5 | First workers: the nanitics arrive, feeding begins, and the colony slowly climbs towards ten workers.
• Months 6 to 8 | Moving day: at ten or more workers, she is ready for a proper formicarium and a real growth spurt.
• Months 9 to 12 | First winter: growth slows, the queen stops laying, and the colony rests. This is normal and healthy, not a problem to fix.
• The payoff: a black garden ant queen can live nearly 29 years. Year one is the foundation of a pet that can outlast almost any other.
Before You Start: Set Your Expectations
I will be straight with you, because it saves heartache later. Most people who give up on ant keeping do so in the first couple of months, and nearly always for the same reason. They expected a fish tank full of activity and got a quiet tube with a single ant sitting in it. That is not failure. That is exactly how a healthy colony begins.
This guide walks you through a realistic first year with a black garden ant (Lasius niger), the species I recommend to almost every beginner. If you have just caught your own queen, start with our guide on what to do next after catching a queen. If you would rather skip the slow, uncertain founding stage entirely, a ready-started colony with workers already in place puts you months ahead on day one.
Months 1 to 2 | The Founding Stage
Your queen is alone in a test tube with a water reservoir, and that is all she needs. Black garden ant queens are fully claustral, which means she does not eat during founding. She lives off her own body reserves while she raises her first brood. Do not feed her. Do not open the tube. Do not check every day.
Keep her somewhere dark, quiet and steady at 20 to 26°C. A drawer or a cupboard is perfect. Inside the tube, she will lay a small clutch of eggs, and from egg to first worker takes roughly six to eight weeks, a little faster in the warm, slower in the cold. It is slow, and it is meant to be.
The single most common mistake I see is disturbing her. Picture living quietly in a dark room, and every day a giant lifts the roof off your house, blinding you with light. How long would you last? A stressed queen will often eat her own eggs and start again. Leave her be, and let her work.
If you have not bought anything yet and want a colony that skips this fragile stage, our live Lasius niger colonies ship with a queen and workers already established, backed by a live arrival guarantee.
Months 3 to 5 | First Workers and First Feeds
Somewhere around the two- to three-month mark, the first workers appear. These are nanitics, smaller and paler than the workers that follow, and they get straight to work tending the queen and the brood. This is the moment the colony comes alive, and the first worker you see is a genuine milestone.
Now, feeding begins. Offer a small amount of protein jelly and a tiny drop of organic honey twice a week, always in the outworld, never in the nest. For a small colony, an amount the size of a single grain of rice is plenty. Serve the honey on a scrap of cotton wool so nobody drowns in it, and always remove anything uneaten after two days before it turns to mould.
Keep watering with mineral, distilled, or purified water only, never tap or rainwater, which brings fungus, and fungus kills a founding colony. Aim for 75 to 85 per cent humidity in the nest, keeping the outworld drier. Warmth drives growth: at a steady room temperature, the colony grows faster than in a cold room. If your room regularly drops below 18°C, an Advanced Heating System Small 4W with its thermostat holds the right temperature, warming only a quarter of the nest on the opposite side from the water.
Months 6 to 8 | Moving Into a Formicarium
Once the colony reaches ten or more workers, she is ready to leave the test tube for a proper nest. Move her too early, into too much empty space, and a small colony struggles to hold its humidity and settle. Wait for those ten workers, and moving day becomes a milestone rather than a gamble.
This is where a purpose-built kit earns its place. Our Lucas starter kit is designed for exactly this stage of a Lasius niger colony, with the right nest, outworld and a pre-installed digital humidity and temperature meter that takes the guesswork out of it. Follow the full method in our step-by-step setup guide, wrap the test tube in tinfoil for the first fortnight, then slide it out a millimetre or two a day so the ants meet the light gently. Run a strip of PTFE fluon around the top inner edge of the outworld so nobody wanders off at feeding time.
A word of warning I repeat often: never force them across with heat or light, and never pick a nest that dwarfs the colony. Ants should fill roughly a fifth of their space, or they lose track of what is nest and what is larder. Start small and upgrade as they grow.
Spare a thought for the Sateré-Mawé
While you wait on your gentle black ants, consider this. To become men, young lads of the Sateré-Mawé tribe in Brazil pull on gloves woven full of live bullet ants, whose sting tops the pain index and burns for a full 24 hours, and hold them on for ten minutes. Then they do it again, up to twenty times over. Your Lasius niger queen, by contrast, asks nothing of you but patience and the occasional drop of honey. You can read about the bullet ant and four more you would never want in the house in our Five Most Dangerous Ants piece.
Months 9 to 12 | The First Winter Rest
As autumn arrives, everything slows, and this is the part that catches out every first-year keeper. The queen lays less, then stops. The workers turn sluggish. Foraging drops off. Nothing is wrong. This is diapause, the natural winter rest, and it is essential: it strengthens the queen for next summer's laying season.
Lasius niger winds down from around October and picks back up in late March or early April. Here is the bit worth hearing from someone who has watched it for decades: hibernation is not compulsory. Your ants will slow down and rest wherever they are, so if you do not have the equipment or the confidence to cool them properly, do not force it. Simply keep them out of direct sun and away from heaters, keep the water topped up, and let them be. Our hibernation guide covers the full method if you want to do it properly.
Never use a fridge on a whim or drop the temperature suddenly. Come spring, the queen begins laying again, and a colony that started as one ant in a tube heads into its second year properly established.
A Quick Word on the Long Game
Here is why patience pays. A black garden ant queen has been recorded living just short of 29 years, the longest lifespan of any social insect on record. The workers come and go, living a year or two, but the queen you are nursing through this quiet first year could still be laying eggs decades from now. Few pets on earth offer anything close.
Prefer a livelier first year? Messor barbarus harvester ants grow into polymorphic colonies with striking red-headed majors and seed-collecting trails, and they make ant bread from their stores, which is a sight in itself. The Angie starter kit pairs a Messor colony with the same built-in meter. Both are covered in our ant farm buying guide if you are still choosing.
The Bottom Line
Your first year is quiet, then slow, then suddenly rewarding. Leave the queen alone while she founds, feed lightly once the workers arrive, move her at ten workers, and let her rest through winter. Do that, and after three decades of watching people fall for this hobby, I can promise you the payoff: not just a jar of ants, but a colony that can outlive almost everything else in the house.

FAQs
How long does it take to grow an ant colony?
Slowly at first. A Lasius niger queen produces her first workers around two to three months after founding, then the colony climbs from a handful of workers to a busy nest across the first year. Growth is fastest in warm months and pauses over winter. With patience, a Lasius niger colony can eventually reach several thousand workers.
When can I move my ants into a formicarium in the first year of ant keeping?
Once the colony has at least ten workers. Before that, keep them in the test tube, where the humidity and security are ideal. Moving a very small colony into a large empty nest is one of the most common ways beginners lose a queen.
Do I need to feed the queen straight away?
No. A fully claustral black garden ant queen needs no food at all during founding, surviving on her own body reserves until the first workers appear. Only once the workers emerge do you begin feeding, with a little protein jelly and organic honey twice a week in the outworld.
Why has my colony stopped growing in winter?
Because it is meant to. Lasius niger slows from around October as the queen stops laying and the colony rests through diapause. It is natural and healthy, and it prepares the queen for a strong laying season the following summer. Keep the water topped up and let them rest.
Can I go on holiday and leave my ants in the first year?
Yes, they are remarkably low-maintenance. Before you go, water the nest fully and leave a small amount of food in the outworld. A well-moistened colony copes comfortably for a fortnight in the warmer months. For longer trips, ask someone to check the water once a week, and that is all they need.
Is ant keeping a good hobby for beginners?
Yes, provided you start with a forgiving species like Lasius niger, use a proper formicarium rather than a cheap gel or plastic box, and accept that the first year is a slow build. Ongoing costs are low, and the payoff is a long-lived, endlessly watchable colony.
