Can dust formulation be used in insulated walls?

Using dust formulations in insulated walls is generally not recommended due to several factors. Insulated walls are designed to minimize air transfer and maintain energy efficiency, which means that any product applied within them can potentially disrupt this balance. Dust formulations can settle and create pockets of residue, which may lead to uneven distribution of the pesticide, reducing its effectiveness. Additionally, dust can also adhere to the insulation materials and potentially become a source of contamination or negatively interact with the insulation itself.

Moreover, many dusts are designed for specific applications, such as treating cracks, crevices, or open areas rather than enclosed insulated spaces. This can lead to issues with efficacy and safety, as the product may not reach the target pests effectively when confined within the walls.

While certain conditions or specific labeling instructions might allow for dust use in some situations, the overall consensus is that insulated walls create challenges that are not conducive to the effective application of dust formulations, hence why this choice is correct.
