Oregon Pesticide Practice Test

The correct choice for controlling cockroaches inside buildings is a crack and crevice application. This method involves applying pesticides specifically into the small spaces and voids where cockroaches are likely to hide, such as in cracks in walls, around baseboards, and within furniture. Cockroaches are notorious for lurking in hidden spots, and targeting these areas ensures that the pesticides reach them effectively, maximizing the chances of control.

In contrast, other application methods are less suitable for this situation. A broadcast application involves spreading insecticide over a wide area, which is typically more effective for outdoor or large-scale pest control rather than targeting specific hiding spots of indoor pests like cockroaches. An aerial application, as the name suggests, involves dispensing pesticides from above, often for large agricultural areas, and is not practical for indoor use due to safety concerns and ineffectiveness against such specific pests. A soil drench is used to target pests residing in the soil and is irrelevant in the context of controlling indoor cockroaches.
