How long should it generally take for medium to large cutworms to surface after applying a flushing solution?

Flushing solutions are used in pest management to drive cutworms to the surface, allowing for easier detection and control. When applying a flushing solution specifically for medium to large cutworms, it generally takes about 2-3 minutes for these pests to respond and surface. This timing allows the solution enough time to penetrate the soil and disturb the cutworms, prompting them to move toward the surface where they can be more readily targeted for management.

The response time of 2-3 minutes is practical, as it strikes a balance between allowing the solution to act effectively and preventing excessive waiting which could lead to decreased efficacy in finding and treating the pests. Choosing this specific timeframe helps ensure that the pests are not allowed to retreat or become re-embedded in the soil before they can be targeted.

In contrast, the other options suggest either a timeframe that is too short or too long, which would not provide the best chance of successfully bringing the cutworms to the surface in a manageable time frame.
