Western subterranean termites
Subterranean Termite Control in Ontario
UC Statewide IPM describes subterranean termites as soil-connected insects that need moisture and build earth-hardened mud tubes to reach the framing above. Working tubes climb foundations, while drop tubes hang from wood back toward the soil. The common Reticulitermes group swarms on clear afternoons after a soaking rain, which in Ontario means winter storms. Warm, damp spots under buildings suit foraging, so leaking sprinklers and irrigation near a slab are worth fixing.
