True or False: Spring treatments are the most effective for controlling white grubs.

Spring treatments are not typically the most effective for controlling white grubs, which is why the answer is false. White grubs, particularly the larvae of beetles such as Japanese beetles, tend to emerge and feed during the summer months. By focusing control efforts in late summer to early fall, when the grubs are more actively feeding and vulnerable, pesticide applications are more likely to be effective.

Timing of application is crucial in pest management. For grubs, targeting them during their most active feeding periods ensures that pesticides can be more effective in reducing their populations. Therefore, fall applications tend to yield better results compared to those made in the spring, when the grubs may not yet be active or are still in egg or early larval stages.
