Behaviour, Biology & Habitat
Termites are wood-destroying insects belonging to the order Blattodea — closely related to cockroaches — and are among the most economically destructive pests in Singapore. They are eusocial insects operating in strictly organised colonies with distinct castes. The most common and destructive species in Singapore is the Asian Subterranean Termite (Coptotermes gestroi), which forms underground colonies of up to five million workers connected by tunnel networks extending hundreds of metres.
Termites feed on cellulose found in timber, paper, cardboard and other plant-based materials. What makes them uniquely destructive is their concealed feeding pattern — they consume structural timber from the inside while preserving the surface skin intact, meaning floors, walls and roof beams can be almost entirely hollowed out before any visible surface damage appears. A mature colony consumes 300 to 400 grams of wood per day.
Singapore’s warm, humid climate — averaging 27°C and 84% relative humidity — creates ideal year-round conditions for termite activity. Subterranean termites nest underground or within moisture-rich timber and construct mud shelter tubes along walls, pipes and foundations to travel between nest and food sources. These tubes are one of the most reliable early warning signs of infestation.
Annual professional termite inspections are the single most cost-effective protective measure for any Singapore property. Our termite control services → use baiting systems, soil termiticide treatment and thermal imaging inspection to detect and eliminate infestations before structural damage occurs.
Termite Characteristics
Termites are highly evolved social insects with sophisticated colony structures, specialised castes and a concealed lifestyle that makes them one of the most difficult pests to detect and eliminate without professional tools and treatment systems.
Termites undergo incomplete metamorphosis through three main stages: egg, nymph and adult. A fertilised queen can live for 25 years or more and in mature colonies lays thousands of eggs daily. In Singapore’s climate, eggs hatch within 24 to 36 days. Nymphs develop through multiple moults and differentiate into workers, soldiers or reproductive castes depending on pheromone signals from the existing colony.
New reproductive termites — known as alates — are produced seasonally. These winged termites swarm to establish new colonies, typically emerging in the evening hours after rain between April and July in Singapore. Swarming alates are often the first visible sign of a nearby colony. After landing they shed their wings and pairs attempt to found new colonies in moist timber or soil.
Colony growth is slow in the first year while the founding pair tend the first generation alone. Once workers mature, growth accelerates rapidly. A mature Coptotermes gestroi colony can reach three to five million individuals within five to seven years in Singapore’s conditions.
Termites are soft-bodied insects distinguished from ants by three key features: straight, beaded antennae (ants have elbowed antennae); a broad, unconstricted waist (ants have a pinched petiole); and two pairs of equal-length wings in reproductives (ants have unequal pairs). Correct identification is critical as termite and ant treatments are entirely different.
Workers are pale cream and blind, 4 to 6mm in length. Soldiers are larger with hardened, pigmented amber heads and powerful mandibles. In Coptotermes species, soldiers produce a white milky defensive fluid from a frontal gland — a key identification feature. Reproductive alates are darker with compound eyes and wings, up to 15mm including wings.
Termites rely on symbiotic microorganisms — protozoa and bacteria — in their hindgut to break down cellulose into digestible compounds. Combined with trophallaxis (mouth-to-mouth food sharing), this allows the colony to efficiently exploit cellulose sources that most other organisms cannot utilise.
Termites feed on cellulose found in wood, paper, cardboard, fabric, carpeting and any other plant-based material. In Singapore’s urban environment, subterranean termites readily attack structural timber, engineered wood products, plywood, particleboard and the paper backing of drywall. No cellulose-containing material should be considered safe from a well-established colony in the vicinity.
A single mature Coptotermes gestroi colony can consume 300 to 400 grams of wood per day. Critically, termites feed from the inside of timber outward, maintaining the surface skin intact. This means floors, skirting boards and structural beams can be almost entirely consumed before any visible surface damage appears — a key reason why annual professional termite inspection is recommended for all Singapore properties.
Termites do not feed on metal, concrete or plastic, but will tunnel through these materials to reach cellulose food sources. They are also attracted to moisture-damaged timber, making any area with water ingress, leaking pipes or inadequate drainage a high-risk zone for infestation.
Termite colonies comprise the royal pair (king and queen), workers, soldiers and reproductives. In Coptotermes gestroi — Singapore’s most destructive species — a mature colony can contain three to five million workers and may maintain multiple satellite nests connected by an underground tunnel network extending hundreds of metres from the primary nest site.
The queen becomes physogastric in mature colonies — her abdomen swells enormously as egg production scales up to thousands of eggs per day. The king remains with the queen and fertilises her throughout a lifespan of 25 or more years. If the queen dies, secondary reproductives can take over egg production, making colony elimination without professional intervention extremely difficult.
Workers (80 to 90% of the colony) are solely responsible for foraging, feeding all other castes through trophallaxis, nest construction and brood care. Soldiers (5 to 10%) are entirely defensive and cannot feed themselves. Effective treatment must target the entire colony — not just the foragers encountered during surface inspections.
Termite Colony Castes
Termite colonies are divided into four castes, each with a distinct role. Understanding the caste system explains why termite colonies are so resilient — and why eliminating the queen is the only path to permanent control.
Signs of Termite Infestation
Termites are often called the “silent destroyers” for good reason. Their concealed feeding habit — consuming timber from the inside while maintaining the surface intact — means most infestations are discovered only after significant structural damage has already occurred.
Singapore’s year-round warm and humid climate means termite colonies remain active throughout the year with no seasonal dieback. Regular self-inspection of at-risk areas — particularly ground-floor timber, skirting boards, roof voids and areas near plumbing — combined with annual professional inspection is the most effective early detection strategy.
If you find any of the following signs, contact our termite control team → immediately. Do not disturb mud tubes or damaged timber — disruption can cause the colony to relocate, making treatment harder.
Mud Tubes on Walls & Pipes
Subterranean termites build pencil-width mud shelter tubes along walls, pipes, foundations and timber to travel between their underground nest and above-ground food sources. These tubes protect them from dehydration and predators. Finding intact or broken mud tubes — even inactive-looking ones — on any structural surface is a definitive sign of subterranean termite activity requiring immediate professional inspection.
Hollow-Sounding Timber
Termites feed from the inside of wood outward, leaving only a thin surface shell intact. Tapping suspected timber with a screwdriver handle produces a hollow, papery sound rather than a solid thud if the interior has been consumed. Apply this test to all skirting boards, door frames, floor joists and structural timbers in suspected areas. Soft or yielding timber surfaces confirm active or past infestation.
Discarded Swarmer Wings
Reproductive alates shed their wings immediately after landing during a swarm. Small piles of equal-length wings near window sills, light fittings, sliding door tracks and floor edges indicate a recent alate swarm. Because alates are attracted to light, they are typically found near windows and doors. Wing piles confirm a reproductive swarm has taken place and a colony is nearby.
Tight Doors & Warping Frames
Subterranean termites introduce significant moisture into the timber they infest, causing door frames, window frames and flooring to swell, warp and become difficult to operate. Suddenly stiff doors or windows — particularly in areas not previously prone to humidity issues — can indicate active termite infestation in surrounding timber framing. Do not dismiss this as normal seasonal expansion without professional inspection.

Termite FAQs
How do I know if I have termites or ants? ⌄
Termites have a broad straight waist, straight beaded antennae and two equal-length pairs of wings. Ants have a pinched waist, elbowed antennae and unequal wing pairs. If unsure, collect a specimen in a sealed container and contact us — incorrect identification leads to ineffective treatment.
Can termites damage a concrete or brick building? ⌄
Concrete and brick are not food sources, but subterranean termites tunnel through hairline cracks and expansion joints to reach timber inside walls, flooring and roofing. Most damage in Singapore occurs to the timber components of concrete and masonry buildings — rafters, floor joists, skirting boards and door frames.
How quickly can termites destroy a property? ⌄
A mature Coptotermes gestroi colony consumes 300 to 400 grams of wood per day. Significant structural damage typically occurs over two to five years of undetected infestation, with full repairs potentially costing hundreds of thousands of dollars. Annual inspection is the most cost-effective protection measure.
What is a termite baiting system and how does it work? ⌄
Bait stations installed around the property contain a cellulose matrix that foraging workers carry back and share throughout the colony via trophallaxis, eliminating the queen over 4 to 12 weeks. Baiting is preferred over soil barriers in many Singapore situations as it eliminates the entire colony rather than just blocking access.
How often should I have a termite inspection? ⌄
Annual inspections are the standard recommendation for all Singapore properties. Properties with a history of infestation or those adjacent to soil and mature trees should consider biannual inspections. Our inspectors use moisture meters and thermal imaging to detect infestations concealed within wall cavities — invisible to the naked eye.
