MDARD Michigan Core Pesticide Applicator Practice Exam

What type of application should be used to control cockroaches inside buildings?

1. Broadcast application

2. Crack and crevice application

3. Soil treatment

4. Foliage application

The correct answer is: Crack and crevice application

Using a crack and crevice application is the most effective method for controlling cockroaches inside buildings for several reasons. Cockroaches are nocturnal and tend to hide in small, tight spaces such as cracks, crevices, and other sheltered areas. A crack and crevice application allows pesticide products to be applied directly into these areas where cockroaches are likely to reside, increasing the likelihood of contact with the pest. This approach minimizes pesticide exposure to non-target areas and organisms, as the treatment is localized rather than broad-spectrum. It focuses on areas where cockroaches are known to congregate or travel, ensuring that the insecticide is applied where it can do the most good. In contrast, a broadcast application would involve spreading pesticides widely over a larger area, which may not effectively target cockroaches hiding in specific nooks and crannies. Similarly, soil treatment and foliage application are designed for outdoor or agricultural management rather than indoor pests, making them unsuitable for controlling cockroaches inside buildings. Therefore, the crack and crevice method is the preferred application technique for effective control of cockroaches in indoor environments.
