What is the temperature range that can be effective for termite control through heat treatment?

The correct answer reflects the effective temperature range for heat treatment in termite control. To successfully eliminate termites through heat treatment, it is essential to raise the temperature inside the infested structure to a level that can kill the termites without causing damage to the property itself.

In the range of 120°F to 140°F, termites are exposed to lethal conditions. At temperatures above 120°F, typically within 30 minutes of exposure, termites can be killed. This range is effective because it ensures that the heat penetrates wood and other materials where termites might be living, effectively targeting all life stages of the termites, including eggs, larvae, and adults.

For optimal effectiveness during heat treatment, it is crucial to monitor that temperatures remain within this optimal range, ensuring that the entire area being treated reaches the necessary internal temperature to eradicate the pests. Higher temperatures can be effective but may also risk damaging building materials or other components if not managed properly, which is why the specified range is both effective for pest control and safe for structures.
