What is the primary application method for treating ants in wall voids?

The primary application method for treating ants in wall voids is dust treatment. This method is particularly effective because dust can penetrate cracks, crevices, and voids where ants are nesting or traveling, allowing for thorough distribution of the treatment. Dust formulations adhere to the surfaces within the voids and can remain effective for an extended period, which is essential for targeting ants as they traverse these areas.

Additionally, when ants come into contact with the dust, they can transport it back to their colony, potentially affecting other ants and helping to eradicate the entire nest. Gravity helps the dust settle effectively within wall voids, ensuring that it reaches areas that could be difficult to access with other application methods. This makes dust treatment a reliable option for addressing ant infestations in confined spaces like wall voids.
