Associate Certified Entomologist (ACE) Practice Exam

Which of the following best describes a crack and crevice treatment?

1. A large volume of pesticide for general areas

2. A limited application into small inaccessible areas

3. Spraying wide open spaces

4. Using sticky traps for monitoring

The correct answer is: A limited application into small inaccessible areas

The best description of a crack and crevice treatment is a limited application into small inaccessible areas. This method focuses on applying pesticides precisely into cracks, crevices, and other tight spaces where pests often find harborages. Such targeted approaches minimize pesticide use while effectively addressing pest populations that might go unnoticed in larger areas. This technique is important because many pest species prefer to reside in protected spaces, making broad treatments ineffective for controlling these hidden populations. By directing the application specifically into these areas, pest management professionals can enhance efficacy while adhering to responsible pest management practices. On the other hand, the other options describe approaches that do not closely align with the nature of crack and crevice treatment. For example, using a large volume of pesticide for general areas lacks the precision of focusing on specific harborage sites. Spraying in wide open spaces is too broad and often less effective against pests that are more hidden. Sticky traps are primarily utilized for monitoring pest activity rather than for targeted pest control applications, differentiating them from crack and crevice treatments focused on pesticide delivery.
