The most suitable temperatures for the activity and growth of termites are between 24 and 35 degrees Celsius. In an effort to avoid temperatures that are unfavorable to them, these insects move to the inside of the wood they infect, or to greater depths of the soil, if they live there.

When conditions are not favorable (eg very cold winters), they remain inactive until the temperature rises. In centrally heated buildings, termites are likely to remain active throughout the year.

The soft body of the termites makes them vulnerable to dehydration. On the contrary, the humidity caused by the watering of the lawn around the houses in summer, creates particularly favorable conditions for their spread.
