What do the larvae of White Grubs feed on primarily?

The larvae of White Grubs primarily feed on roots, making this the correct choice. These pests, which are often the immature stage of various scarab beetles, cause significant damage to turfgrass by severing the delicate root systems that support grass. This feeding behavior leads to weakened plants, making them more susceptible to drought and diseases.

Understanding this is crucial for effective pest management, as identifying the feeding habits of pests can help in selecting appropriate treatment strategies. For instance, recognizing that White Grubs target roots may prompt a proactive approach in managing grub populations before they reach damaging levels, particularly during their peak feeding times in late summer through early fall.
