Termites, often referred to as “silent destroyers,” wreak havoc on homes across Australia, causing substantial damage each year. At Newcastle Pest Control, we take termite damage statistics seriously, recognising the importance of safeguarding homes through regular termite inspections. In this comprehensive guide, we delve into the alarming statistics, shedding light on the need for vigilance and protection against these destructive pests.

The Scope of Termite Damage

Each year, termites inflict considerable damage on homes throughout Australia. This underscores the urgency of understanding the scope of the issue and the imperative of preventive measures. Here are some staggering statistics that emphasise the magnitude of the problem:

  • Termites infest and damage approximately one out of every five houses in Australia.
  • Annually, the impact ranges between 130,000 and 180,000 Australian homes.
  • Remarkably, termites can cause irreparable structural damage within a mere 12 months of invading a home.
  • Insurance companies in Australia do not cover termite-associated costs, irrespective of the extent of damage.

These statistics highlight the urgency of proactive termite management, making regular inspections an integral part of homeownership.

Understanding Termites: Nature and Behavior

What Are Termites?

Termites are often mistaken for ants, but they are distinct insects with unique characteristics. Contrary to popular belief, termites share a lineage with wood-eating cockroaches, and they are not related to ants. These pests feed on cellulose-rich materials like wood, leaf litter, soil, and even animal dung. While termites play a beneficial role in the environment by decomposing dead plant matter, their affinity for cellulose makes them a significant threat to man-made structures.

Termites’ Nesting and Growth

Termites operate in organized colonies, differentiating into “workers” and “soldiers,” often sterile members of the colony. Their nests, starting small, grow as the colony does, often reaching depths of a foot and a half underground. These nests can extend up to 50 or 100 meters away from their foraging locations, expanding in range as the colony’s size increases. Unfortunately, the longer a nest persists, the more destructive it becomes.

Diversity of Termites in Australia

Largest Termite Population

Australia is home to over 350 termite species, with approximately 40 species being invasive and destructive. While precise numbers are challenging to estimate, trillions of these pests are believed to inhabit the continent. A single termite colony can host over a million individuals, with queens living up to 15 years (or even 50 years in some species). Worker termites, attending to the queen, typically live for about six years. Each year, around 60,000 alates (winged termites) leave parent colonies to mate and establish new colonies, creating a continuous cycle of growth.

Most Destructive Types

Approximately 40 species of termites are both intrusive and destructive, grouped into three categories based on nesting and feeding habits:

  1. Subterranean Termites: These live in or near the ground, requiring moisture to survive. They target wood and cellulose-containing materials, causing extensive damage to timber structures.
  2. Drywood Termites: Nesting within timber, they consume both hardwood and softwood but need high moisture levels.
  3. Dampwood Termites: Larger in size, these termites inhabit moist wood and indicate potential moisture problems in homes.

Detecting and Addressing Infestations

Signs of Infestations

Identifying termite infestations is crucial for timely action. Common indicators include discarded wings near windows, flying winged termites indoors, hollow-sounding timber upon tapping, bubbled or cracked paint on timber, presence of dry, sand-like faecal pellets, and frass found in cone-shaped piles or circular patterns.


Understanding termite damage statistics and the behavior of these pests underscores the necessity of vigilance. Regular termite inspections and preventive measures are essential for protecting homes from the significant and often irreversible destruction caused by termites. By staying informed and taking proactive steps, homeowners can ensure their properties remain safe and secure from these silent invaders.
