When are control measures for white grubs usually most effective?

Control measures for white grubs are most effective during late summer when the grubs are actively feeding just below the soil surface, making them more vulnerable to treatment. During this time, they are close to the surface and at a stage of development that allows pesticides to be more effective.

Applying control measures during early spring or fall typically does not align with the life cycle of white grubs when they are less active or have not yet emerged. Likewise, addressing the problem in the first or second week of the season may be too early, as it may not coincide with the periods of peak activity for the pests. Effective management of white grubs relies on timing treatments to coincide with their life cycle stages, particularly when they are small and actively feeding.
