What Do Termites Look Like? An ID Guide

Termites are pale, soft-bodied insects with a straight-sided body, not the pinched waist of an ant. Most of what you see in a colony are workers, pale and blind, with soldiers recognisable by a larger, darker head and jaws. Winged reproductives, called alates, appear during a swarm. The mess they leave also tells a story: fine black dust is ant frass, solid brown mud is termite workings.

The three termite types you might see

A termite colony has workers, soldiers and reproductives, and each looks different. Workers are pale, soft and roughly ant-sized, and they are the ones doing the feeding, so they are the type most often mistaken for something else. Soldiers have a noticeably larger, darker head with pincer-like jaws, built to defend the colony rather than feed. Alates are the winged reproductives that swarm to start new colonies, usually after rain in warmer months, and are often what people notice first when wings turn up on a windowsill.

Termite versus ant: the quick tells

Look at the waist and the colour. Termites are straight-sided along the body with no pinch at the waist, and pale, almost translucent. Ants have a distinct narrow waist and are usually darker. The antennae differ too, straight on a termite, bent or elbowed on an ant. If you are not sure which you are looking at, the safest move is to leave it undisturbed rather than spray it.

What the frass tells you

The material left behind is one of the clearest tells. Ant frass is fine, black and dusty, almost like sawdust. Termite workings are a solid brown mud, used to build the tunnels they travel through, and it does not brush away like dust does. Finding brown mud tubes on a wall, skirting or in the subfloor points to termites, not ants, and is worth having checked properly.

Common questions

How can I tell if it is a termite and not an ant?
Check the waist and colour. Termites are pale and straight-sided with no pinch at the waist. Ants are darker with a narrow, pinched waist. The frass differs too, fine black dust for ants, solid brown mud for termites.

What does termite frass look like?
Solid brown mud, not fine dust. Termites use it to build the tunnels and workings they travel through, so it tends to sit in a defined shape rather than scatter like dust.

Are flying termites dangerous?
Winged termites, or alates, are not dangerous to people, but they signal a nearby colony large enough to swarm and start a new one. Finding discarded wings is worth having a professional take a look at.
