Dusts are primarily used in which type of pest control?

Dusts are primarily used in outdoor barrier treatments due to their ability to provide long-lasting residual control against pests. When applied to surfaces outdoors, dust formulations can adhere well to various substrates and create an effective barrier that pests must cross. This is crucial for managing insects and other unwanted organisms that may enter structures or invade gardens and landscapes.

The physical form of dust allows it to penetrate cracks, crevices, and other hard-to-reach areas where pests may hide. Additionally, dusts can remain effective for longer periods compared to other formulations, making them ideal for use in outdoor applications where conditions such as rain or wind could wash away liquid treatments.

While dust applications can be utilized indoors as well, they are particularly advantageous for establishing an outdoor barrier, protecting buildings or plants from insect invasions. This makes them a preferred choice in outdoor pest management strategies, as they help prevent pests from encroaching into living or working spaces.
