Which type of pests typically do not need control under normal conditions?

The correct choice refers to potential pests, which typically do not require control under normal conditions. This category of pests includes species that may become problematic under certain circumstances, such as changes in environmental conditions or increases in food supply. However, they generally do not pose a significant threat to health or property under typical circumstances, allowing for flexibility in management.

In contrast, continuous pests are those that are consistently present and require ongoing control measures. Sporadic pests appear intermittently and may need attention during specific seasons or situations, while vertebrate pests often necessitate management due to their larger size and potential to cause extensive property damage or health risks. Thus, potential pests remain manageable without constant intervention.
