At the heart of every ant colony lies the most important member: the queen ant. She’s not just any ordinary ant. Her role is vital to the survival and success of the colony.
In many ant species, the queen is the sole reproducer. Without her, the colony could no longer produce new workers, soldiers, or reproductive ants. In this post, we cover what a queen ant is, how an ant becomes a queen, her role in the colony, and more.
TL;DR
- A queen ant can live for 10–30 years depending on species — far longer than worker ants (weeks to a couple of years) or males (days to weeks).
- She is noticeably larger than worker ants, with a bigger thorax and swollen abdomen. The UK’s most common species, the black garden ant (Lasius niger), has a queen around 9mm long versus workers at 3–5mm.
- Young queens have wings, which they shed after mating — shed wings are a key identification clue.
- Her only role is egg-laying. She does not command the colony; workers act independently.
- Without a queen, a colony cannot produce new ants and will die out within months.
- In the UK, queen ants appear above ground during nuptial flight, typically in July–August (flying ant day).

What Is an Ant Queen?
The queen ant is the reproductive leader of an ant colony. Her only real job is to lay eggs and keep the colony’s population going. Without her, no new ants are born, and the colony eventually collapses. The most commonly encountered queen ant in the UK is the black garden ant (Lasius niger) — the one most likely responsible for any ant problem in or around a typical British home.
Do All Ants Have a Queen?
Yes. Every ant species organises its colony around at least one queen. Most colonies are monogyne, meaning they have a single queen. However, some species, including certain fire ant and pharaoh ant colonies, are polygyne — they have multiple queens laying eggs at the same time. A colony without any queen at all cannot sustain itself; it can only survive for as long as the existing workers live.
Does the Queen Control the Colony?
No, the royalty in an ant nest doesn’t give out orders. Its main role is to reproduce, so there are enough workers to support and contribute to the colony. In fact, the workers decide which tasks to do by themselves. Whatever they prefer, that’s what they do.
How Long Does a Queen Ant Live?
A queen ant can live for 10–30 years depending on species and conditions — far longer than worker ants or males. Workers typically survive for weeks to a couple of years depending on their species and role. Males fare even worse: they live for just days to weeks, dying shortly after mating. The queen, by contrast, can keep laying eggs for decades in the right environment, which is what makes her so central to the colony’s long-term survival.

Lifecycle of Queen Ants
Queen ants lay eggs that develop into larvae. The larvae are fed and nurtured by worker ants until they pupate and emerge as adult ants. The queen’s role is solely to lay eggs, while worker ants manage the rest of the colony, including tending to the larvae.
- Egg: The queen ant lays thousands of eggs during her life. She can produce fertilised eggs, which develop into female workers or future queens, or unfertilised eggs, which develop into males — a process known as haplodiploidy.
- Larvae: These hatch from eggs and require care and feeding. Worker ants tend to the larvae and regulate how much food each receives, which influences whether a larva develops into a worker or a queen.
- Pupae: After sufficient growth, larvae spin a cocoon and pupate. The queen plays no active role at this stage — workers manage the pupae until they are ready to emerge.
- Adult Ant: Fully developed ants emerge from pupae. Those destined to be new queens will have wings and will eventually leave the nest to mate and found colonies of their own.
How Are Queen Ants Born?
A queen ant is not born differently from other female ants. She is typically selected as a larva and given more food than the rest, which triggers queen development. In some species, genetic factors or the specific egg chosen by the colony determine who becomes queen. The selection process varies widely across the more than 12,000 known ant species. For example, harvester ants select their queen while it is still at the egg stage. Other species feed one larva with more royal jelly than the rest, and that individual grows up to become the colony’s queen.
What Does A Queen Ant Look Like
A queen ant is noticeably larger than worker ants — typically two to three times their size. She has a larger, more muscular thorax, built to support the wing muscles she uses during her mating flight, and a swollen abdomen designed for egg production. Young queens have wings; these are shed after mating, so a wingless ant that’s considerably larger than the workers around her is likely a mated queen. In terms of size, the queen of the UK’s most common species, the black garden ant (Lasius niger), measures around 9mm, while workers are typically just 3–5mm long.

Does The Queen Ant Ever Come Out?
You will rarely spot a queen ant outside of the nest because she spends most of her life laying eggs. If the queen is out of the nest, that means it is mating season, and she’s on the prowl for a mate.
What Happens to Ants When the Queen Dies
When the queen ant dies and there is no replacement, the colony is finished. Workers may initially seek new colonies to join or simply disperse, but without a queen to lay eggs, no new ants are hatched to replace those that die off. The colony typically collapses within a few months.
What Happens If A Queen Ant Bites You?
If a queen ant bites you, the bite itself is not significantly different from that of a worker ant. Most queen ants do not bite humans unless they feel threatened, and even then, their bite is usually not dangerous. The intensity of the bite depends on the species of the ant.
The queen ant bite may cause mild discomfort or a slight pinch, depending on the size and species of the queen ant. Some people may experience mild swelling or redness at the site of the bite.
How to Kill Queen Ants?
If you spot a colony of ants or an anthill in your yard, look for one specimen that is larger than the rest or has wings. That is usually the queen.
Locate the queen
Look for the largest ant in the colony or one that has wings. If you can only see workers, follow them back toward the nest — the queen will be somewhere inside, typically in the deepest, most protected chamber.
Treat the nest directly
Pour boiling water into the nest entrance to destroy workers and potentially reach the queen. Alternatively, use ant bait — workers carry the toxic bait back to the nest and feed it to the queen, which is often more effective than surface treatments alone. Check out the ant colony control options available to help you choose the right approach.
Call in professional treatment
If the queen cannot be reached, or the colony keeps returning, professional pest control is the most reliable option. A qualified technician can treat the nest directly and confirm the queen has been eliminated.

Facts About Queen Ants
- Most ants you see anywhere are female workers.
- Despite the royal title, a queen ant isn’t the monarch of the colony. The only two services that the workers perform for her are to clean her and bring her food. She doesn’t give orders to the rest of the colony but plays a central role in the common good.
- When ants leave their nests to mate and establish new colonies, a phenomenon called “nuptial flight” causes flying ants to appear suddenly. In the UK, this typically happens in summer, most commonly during July and August.
Frequently Asked Questions About Queen Ants
Can a colony have more than one queen?
Yes. Some ant species are polygyne, meaning a single colony can have multiple queens laying eggs simultaneously. Certain fire ant and pharaoh ant colonies work this way. Others are strictly monogyne — one queen only — and workers will kill any rival queens that emerge.
How does a queen ant start a new colony?
After her mating flight, a newly mated queen lands, sheds her wings, and finds a suitable spot to dig her first chamber. She then begins laying eggs alone, feeding the first larvae on stored fat reserves and nutrients released from her now-redundant wing muscles. She doesn’t eat during this founding stage. Once the first workers emerge, they take over foraging and the queen focuses entirely on egg-laying.
What is the difference between a queen ant and a flying ant?
Flying ants are reproductive males and virgin queens during the nuptial flight period. Both have wings at this stage, which is why people often confuse them. After mating, the male ants die within days. The mated queen loses her wings, finds a nesting site, and becomes the colony’s permanent egg-layer. So a flying ant and a queen ant can be the same individual — but only briefly, right at the start of her life as a colony founder.
Professional Ant Pest Control
Pest control strategies often aim to either eliminate the queen ant directly or disrupt her ability to reproduce. Sometimes only some of the workers get inside your home to forage for food, which makes it harder to pinpoint where they’re coming from. If there’s an entire colony nearby, you can follow the workers back to their entry point. If you can’t get on top of the problem yourself, it’s worth calling in professional ant extermination services rather than letting things escalate.
