In targeted area applications, dust formulations are often preferred due to their ability to adhere to surfaces and penetrate target areas effectively. Dusts are typically very fine particles that can be applied in a way that focuses on a specific location, such as cracks, crevices, or plant foliage, without drifting away significantly. This precision is beneficial in ensuring that the pesticide reaches the intended pest while minimizing exposure to non-target organisms and reducing the risk of environmental contamination.

Dusts can also provide a longer residual effect, as they can remain in place for extended periods, allowing for sustained control of pests in particular sites. Their use in confined spaces or in situations where liquid applications might lead to excess runoff also makes them an ideal choice for targeted applications.

In contrast, other formulations such as granular, liquid, or emulsifiable concentrates may not offer the same level of precision and could affect a larger area than intended. Granular formulations may be less effective in situations requiring immediate contact, while liquids can create drift and potentially impact non-target areas, increasing the risk of environmental harm. Emulsifiable concentrates, while effective, often require thorough mixing and can also lead to overspray or runoff if not carefully managed. Thus, for targeted applications, dust formulations stand out as the most efficient
