Agave Pests

Snout Nosed Weevil

• The snout nosed weevil feeds on all parts of the agave, including the roots, flowers, leaves and stems. Damage to the plant takes place when the brownish-black female weevil cuts its way into the base of the agave and lays its eggs. Microbes that cause plant decay follow the weevil into the plant's base and soon the agave begins to wilt. Weevil eggs hatch and the larvae mature within the dying plant.

Cactus Longhorn Beetle

• The cactus longhorn beetle female lays her eggs at the base of agave stems and the larvae tunnel their way into the pulpy part of the leaf as they mature. They frequently excavate their way into the roots of the agave and cause the plant to die. Longhorn beetles also feed on the buds of agave blooms.

Agave Plant Bugs

• The agave plant bug is nearly 1 inch long and appears to be wearing bright red socks. They crawl on all parts of the agave plant and prefer feeding on the tender edges of its leaves. They often congregate on a leaf in groups and cause extensive damage as they feed. The damage they cause is identified by the light yellow scars or spots that remain on the affected leaf.

Ground Pests

• Ground squirrels, rabbits, mice, and gophers all enjoy eating portions of agave plants. They are gnawing and chewing pests well known for their ability to destroy agave quite easily. The four-footed pests are quite destructive during prolonged dry spells. They attack both young and old agave in their search for sustenance. In instances where the damage is not extensive, the plant may survive and an agave that has severe damage may not recover at all.
