When using sticky traps, where should they ideally be positioned for maximum effectiveness?

1. In the middle of large open spaces

2. Against walls where insects are most likely to travel

3. In uncrowded and remote areas

4. On furniture to attract pests

The correct answer is: Against walls where insects are most likely to travel

Positioning sticky traps against walls is ideal for maximizing their effectiveness because many insects tend to travel along edges and surfaces where they can easily navigate. Insects like cockroaches, ants, and other pests often follow pathways that are less exposed, seeking shelter and food sources, which frequently leads them to walls. By placing the traps in these areas, the likelihood of capturing more insects increases since they are drawn to the traps as they move along these routes. While traps placed in open spaces may capture some insects, those areas generally lack the pathways that insects prefer. Similarly, positioning traps in uncrowded or remote areas may result in fewer insect encounters, as these places are outside the common routes insects utilize. Lastly, placing traps on furniture might not capture many pests, as many insects do not naturally travel vertically or may avoid exposed areas. Thus, the effectiveness of traps is optimized when aligned with insects' natural travel behavior, which is predominantly along walls.
