Associate Certified Entomologist (ACE) Practice Exam

What is a recommended practice for the placement of light traps?

1. Near building entrances and windows.

2. In direct sunlight outdoors.

3. Far from any food processing areas.

4. In the middle of rooms with good airflow.

The correct answer is: Far from any food processing areas.

The recommended practice for the placement of light traps is to locate them far from any food processing areas. This strategy is critical for preventing the attraction of pests that are drawn to the light, thereby minimizing the risk of contamination in areas where food is prepared or stored. Keeping light traps away from these sensitive zones helps to ensure that any attracted insects do not compromise hygiene and safety standards. While placing light traps near building entrances and windows may seem logical as these are potential entry points for pests, this can inadvertently lead to attracting insects into the structure itself. Installation in direct sunlight is counterproductive as it can diminish the effectiveness of the trap; many insects are more active and attracted to artificial light during the evening and nighttime. Positioning traps in the middle of rooms with good airflow can also be ineffective, as it may not adequately draw pests away from movement patterns that could lead them into undesired areas. Thus, situating light traps far from food processing areas effectively mitigates risks associated with pest control, ensuring that food safety is prioritized.
