Subterranean termites (those most commonly seen in homes) are a similar size to a black ant except they are pale in colour. That’s why they are often called “white ants”. If you look closely, termites have two sections to their body while ants have three.
Soldier termites have a slightly darkened, or brown, head. You will also see termites with wings, called alates. Sometimes confused for moths, the allates fly out from the colony in search of a new environment in which to reproduce and develop a new colony.
