Which of the following is a common application method for granular insecticides?

Granular insecticides are often applied in a ready-to-use format, especially when targeting pests that are likely to be found around the perimeters of buildings. This method involves spreading the granular formulation uniformly over the soil or surfaces where pest activity is observed or anticipated, creating a barrier that can effectively control insect populations.

The ready-to-use application allows for convenience and efficiency, as it does not require mixing or complex application equipment, making it accessible for both professional pest control operators and homeowners. This method is particularly effective in preventing pests like ants and termites from entering structures, as it provides direct contact with the insects upon their movement through treated areas.

Other application methods, such as mixing with water for sprays or injecting into walls, are more suited to liquid formulations and specific types of treatments for targeted pest control. Using traps is focused on monitoring or capturing individual insects rather than treating an area comprehensively. Consequently, the ready-to-use application around building perimeters stands out as a common and practical approach for granular insecticides.
