Termite

Termites are eusocial insects that feed on cellulose-rich material such as wood, leaf litter, and soil humus.

Updated July 30, 20261 min readCited sources

Termites are eusocial insects that feed on cellulose-rich material like wood and leaf litter, living in colonies with specialized castes. While a few species are notorious for damaging buildings, most play a vital ecological role in breaking down dead plant matter and recycling nutrients.

What it is

Termites are insects historically classified in the order Isoptera, but modern taxonomy places them within the cockroach lineage. They digest cellulose with the help of symbiotic microbes in their gut. More than 2,000 species exist worldwide, with the greatest diversity in tropical regions.

Why it matters

In nature, termites decompose dead wood and plant material, recycling nutrients into the soil and supporting plant growth. However, a minority of species are major structural pests, infesting homes, fences, and furniture, especially where moisture conditions allow. In Canada, several species can damage wood in buildings.

Key details

Termite colonies include workers, soldiers, and reproductives. Workers and soldiers are typically wingless; reproductives develop wings for swarming to establish new colonies. Colonies can number from thousands to millions. Most termite species are harmless or beneficial in natural ecosystems.

In short

  • Termites are social insects that eat cellulose with help from symbiotic microbes.
  • Only a minority of species damage buildings; most are beneficial decomposers.
  • Termites are found worldwide, with highest diversity in the tropics.
  • In Canada, termites can infest wood in homes, especially in moist conditions.
Canadian angle

Termites are relevant to Canadian readers because several species occur in Canada and can damage wood in homes and buildings, especially where moisture conditions allow infestations. Their ecological role is also relevant to Canadian forests and soils.

Quick questions

What are termites?
Termites are social insects that feed mainly on cellulose from wood and other plant material.
Are termites ants?
No. They are not ants; modern taxonomy places termites closer to cockroaches than to ants.
Do all termites damage houses?
No. Only a minority of termite species are major structural pests; most live in natural habitats and help decompose dead plant material.
