Which application technique involves utilizing heat to vaporize insecticides?

The application technique that involves utilizing heat to vaporize insecticides is thermal foggers. Thermal fogging is a method used in pest control to create a fine mist or fog of pesticide droplets that can penetrate areas where insects may be hiding. By heating the insecticide, it vaporizes and allows for better distribution and coverage within the treatment area. This technique is particularly effective for outdoor applications or in open spaces, as the fine particles remain suspended in the air and can cover a large area quickly.

Using thermal foggers can be advantageous in treating flying insects like mosquitoes or other pests that are mobile and difficult to target with traditional liquid sprays. The heat generated in this process ensures that the pesticide remains effective and can disperse evenly, maximizing the impact on the pest population.
