What is the preferred treatment process for hidden spaces and around root balls?

The preferred treatment process for hidden spaces and around root balls is rodding. This method involves using a flexible rod to reach and treat areas that are not easily accessible, such as underneath structures or in tight spaces where pests may be hiding. Rodding allows for targeted treatment, effectively delivering pesticides into these concealed locations where pests often proliferate.

In contrast, spraying an insecticide is typically more effective for surface treatments and may not adequately penetrate hidden spaces. Using bait stations is beneficial for specific pest control scenarios but may not reach areas surrounding root balls or within hidden spaces as effectively as rodding does. Injecting foam pesticide can be useful for filling voids and treating specific areas, but rodding provides the advantage of locating and treating areas directly affected by pest activity. Therefore, in the context of addressing pests in hidden spaces and around root balls, rodding is the most suitable and efficient method.
