What is the primary reason for using powders in pest control?

The primary reason for using powders in pest control is their long-lasting effects. Powders are formulated to adhere to surfaces and can remain effective over time, allowing them to continue working against pests even after initial application. This longevity is particularly beneficial for controlling insects that may come into contact with treated areas long after the treatment has been applied.

Additionally, powders can be effective in a variety of environments and can remain stable without degrading quickly, making them suitable for ongoing pest management strategies. Although powders may also offer ease of handling and can be effective in dry conditions, these are secondary advantages compared to the primary benefit of their persistence in controlling pest populations.
