How to Manage Pests

Pests in Gardens and Landscapes

Yucca weevil—Scyphophorus yuccae

Yucca weevil adults are black snout weevils about 0.5 inch long. Larvae are white grubs. They are known only to damage yucca plants.

Identification of species


Weevil larvae tunnel into the base of green flower stalks and the heart of the yucca plant. Leaves are punctured with holes. The entire plant declines.


Provide plants with proper cultural care. No other management is known.
