Final answer:
You can catch flying insects like house flies or blow flies using a trigger trap like a Venus flytrap, which should be placed in areas where these pests are active.
Step-by-step explanation:
The type of pest you would be most likely to catch with a trigger trap is typically a flying insect, such as the house fly or blow fly. A common example of a trigger trap is the Venus flytrap, which has specialized leaves that snap shut when the sensitive triggers inside the leaf are touched by an insect. To effectively use trigger traps, they should be placed where the target pests are most active, which often includes near food sources, windowsills, or trash collection areas.
