When should treatments for white grubs in Tennessee be made?

Treatments for white grubs in Tennessee should ideally be made from mid-July to early August. This timing is crucial because it aligns with the life cycle of the most common white grub species found in the region, particularly the Japanese beetle and other similar pests. At this time, the grubs have typically hatched and are in their most vulnerable stage, making them more susceptible to control measures.

Applying treatments during this period enhances the effectiveness of the insecticides and increases the likelihood of reducing or eliminating the grub population before they can cause significant damage to lawns and ornamental plants. Additionally, treating in mid-summer ensures that the products used will target the grubs before they mature into adults and potentially lay more eggs, leading to future infestations. This preventive approach is key to maintaining healthy turf and ornamental areas in Tennessee.
