When is the optimal time to control bluegrass billbug larvae?

The optimal time to control bluegrass billbug larvae is in June because this is when the larvae are actively feeding and thus most vulnerable to pest management treatments. During this month, the larvae are in the early stages of their development, and targeting them at this time can effectively disrupt their life cycle and reduce their population in the soil.

Applying control measures when the larvae are actively feeding significantly increases the chances of successful pest management, as the newly hatched larvae will be present and feeding on the grass roots. This timing aligns well with the biological cycle of the bluegrass billbug, allowing for effective intervention before substantial damage can occur to turfgrass systems.

Implementing control measures at other times may miss the peak activity of the larvae, leading to less effective control and potential for increased damage to the turf.
