Can white grubs kill a arborvitae?

Yes, white grubs can potentially harm arborvitae, particularly if their population is large. These larvae primarily feed on the roots of plants, which can lead to stunted growth, yellowing foliage, and even death if the root system is severely damaged. While arborvitae can withstand some root disturbance, extensive feeding by white grubs can compromise their health and vitality. Regular monitoring and appropriate pest management can help protect these trees from white grub infestations.
