What is the lifestyle of termites? Because they live in the dark, underground or deep within our homes, these insects are often shrouded in mystery. However, understanding their social structure, habits, and reproductive patterns helps us understand how they manage to colonize a building… and why they go unnoticed for so long.

Key Points
- Termites live away from light.
- Each individual plays a specific role within the colony.
- The workers provide food for all the other termites.
- This reproductive strategy sometimes leads to the formation of new colonies.
Termites live in the dark
In metropolitan France, the main infestations of buildings are caused by subterranean termites of the genus Reticulitermes. Five species of this genus have been identified in the country, along with one drywood termite, Kalotermes flavicollis. This is a far cry from the impressive, cathedral-like termite mounds built by certain African species.
Subterranean termites primarily live in environments protected from light and drying out. They move through the soil, their tunnels, or deep within materials, which makes them difficult to detect.
Their whitish bodies are generally 5 to 8 mm long. The light color of many workers sometimes earns them the nickname “white ants,” even though termites and ants belong to different groups of insects.
An underground lifestyle that makes infestations difficult to detect
Termites build a network of tunnels that allows them to move between their colony and their food sources without being exposed to light. This structure explains why the initial damage is often invisible. This phenomenon is detailed in our feature on invisible damage caused by termites.

Termites have a highly organized way of life
Termites are social insects. They live in colonies, within which each individual performs a specific role. This highly efficient organization, often compared to that of ants or bees, explains their ability to develop and maintain colonies that can sometimes consist of several hundred thousand individuals. However, termites belong to a different group of insects than ants, despite certain similarities in their way of life.
The Workers: The Driving Force of the Colony
Worker ants are the most numerous… and also the most active. Their job is to feed their fellow ants, maintain the tunnels, care for the young, and constantly search for new sources of cellulose.
They are prospecting They constantly consume wood, cardboard, or paper. They break down this cellulose, digest it, and then redistribute it to other members of the colony through a process called trophallaxis.

The Soldiers, the Colony’s Protectors
The soldiers are also whitish in color, but they are immediately recognizable by their large heads and powerful mandibles—true weapons designed to defend the colony against predators, particularly ants.
Although they help protect the colony, they are unable to feed themselves. They are therefore entirely dependent on the workers, who feed them through trophallaxis. This division of labor contributes to the colony’s remarkable efficiency.
Breeding birds ensure the colony’s survival
Reproduction is primarily carried out by a primary breeding pair—the king and the queen—which are descended from winged breeders. After the colony is established, the queen lays the eggs, while the king continues to play a role in reproduction.
This highly hierarchical organization allows the colony to grow sustainably while distributing tasks among its various members.
The main members of a colony
| Category | Lead Role |
| Workers | Forage, feed the colony, build tunnels, and maintain the nest. |
| Soldiers | Defend the colony against predators. |
| Breeding Stock | Ensure the colony’s reproduction and growth. |
| Secondary breeders (neotenic) | Help establish or maintain new colonies under certain conditions. |
How does a termite colony develop?
Between January and April, adult flying insects may leave the colony during a phenomenon known as swarming. After they take flight, some form pairs and, when conditions are favorable, may establish a new colony.
However, not all winged breeders establish a new colony; they must find favorable conditions in order to survive and reproduce.
Neotenics: Another Way to Establish a Colony
However, there are also secondary reproducers with barely developed wings, known as neotenic individuals. They appear once the colony has reached a certain stage of development and can ensure secondary reproduction within the colony and, in certain situations, contribute to the formation of new colonial units.
This phenomenon, sometimes referred to as “propagation,” can be facilitated, in particular, by the movement of soil or debris containing termites.
A Constant Attraction to Cellulose
Cellulose is the main food source for termites. It is found in wood as well as in wood-based products such as paper, cardboard, certain types of panels, and other plant-based materials.
To reach the cellulose, they are able to burrow through materials that they do not actually consume, such as drywall, certain types of insulation, and utility ducts. This is why the damage observed often extends beyond wooden components alone.

Understanding their way of life is already a step toward protecting yourself from them
The termites’ lifestyle largely explains their ability to go unnoticed for long periods of time. Their social organization, subterranean lifestyle, constant search for cellulose, and reproductive behavior allow them to discreetly colonize a building without causing any immediately visible signs.
A better understanding of how they operate therefore helps us understand why an infestation can go unnoticed… and why early detection is essential to limiting the damage.

Frequently asked questions
Why do termites avoid light?
Subterranean termites naturally thrive in environments protected from light and desiccation. They move primarily through the soil or inside wood via a network of tunnels that protects them from desiccation and predators.
What is the difference between a worker termite and a soldier termite?
Workers forage for food, maintain the colony, and feed the other members. Soldiers, on the other hand, defend the colony with their powerful mandibles, but they depend on the workers for food.
What is the purpose of trophallaxis?
Trophallaxis is the exchange of food among termites. Workers redistribute food to soldiers, larvae, and reproductive termites. This behavior is essential to the functioning of the colony.
Do all termites build large termite mounds?
No. Subterranean termites of the genus Reticulitermes, which are responsible for many infestations in metropolitan France, live mainly in the soil and do not build the large above-ground termite mounds characteristic of certain tropical species.
Do termites live in wood or in the ground?
It depends on the species. Subterranean termites of the genus Reticulitermes live mainly in the soil and enter wood to feed. The drywood termite Kalotermes flavicollis, which is also found in metropolitan France, lives directly in the wood it colonizes.
Key Facts About the Life Cycle of Termites
- Subterranean termites live mainly in the soil and move about in the dark to reach their sources of cellulose.
- A colony is organized into several castes: workers, soldiers, and breeders.
- Worker bees forage for food and feed the entire colony through trophallaxis.
- Termites reproduce by swarming, but also through secondary reproducers called neotenic termites.
- Their highly efficient organization explains their ability to discreetly infest buildings for many years.
