What is the primary environmental factor that contributes to termite activity?

Moisture is the primary environmental factor that significantly contributes to termite activity. Termites thrive in environments where there is a consistent source of moisture. This moisture can come from the soil, wood, or structural materials that have absorbed water. Because termites rely on moisture for survival, their activity peaks in areas where there is high humidity or consistent rain. They use moisture to maintain their body functions and also to aid in the digestion of cellulose found in wood, making moist environments particularly conducive to their activity.

High temperatures can influence termite behavior and development rates; however, without adequate moisture, high temperatures alone would not support termite colonies effectively. Low humidity and wind are generally not conducive to termite survival, as these conditions would cause desiccation and limit access to essential moisture. Therefore, the presence of moisture is critical for termite colonies to flourish.
