Subterranean termites are widespread in southern Ontario, causing substantial structural damage in urban areas.
Subterranean termites occur in large colonies that live underground and feed on available wood.
Termites can enter a structure by tunnelling through wood or by building shelter tubes over or through cracks in foundation walls. If you suspect that you have termites, you should have an inspection conducted by qualified personnel. However, there are signs that you can check for yourself. Although it is possible that you may encounter the dark, winged alates in early spring, this is rare in Ontario. It is more probable that you will find workers and possibly soldiers.
