If you’re a gardener in the southwestern United States, you’ve probably heard of the agave snout weevil. This destructive pest targets agave plants, including the ones used to make tequila. In this article, we’ll explore the agave snout weevil, its damage, and how to control it.
What is the Agave Snout Weevil?
The agave snout weevil is a type of beetle that grows about an inch long. It’s black in color and has a long, pointed snout. The scientific name for the agave snout weevil is Scyphophorus acupuntatus.
Damage Caused by the Agave Snout Weevil
The agave snout weevil can cause significant damage to agave plants. The adult weevil lays its eggs in the heart of the agave, and the larvae that hatch from the eggs feed on the plant’s tissues. This feeding causes the agave to rot and eventually die.

There are several methods you can use to control the agave snout weevil:
- Triazanon: This chemical treatment is available at most nurseries and garden centers. It’s applied to the soil around the agave and protects the plant from the weevil.
- Resistant Varieties: Planting agave varieties that are resistant to the snout weevil can help prevent infestations.
- Cultural Practices: Keeping your agave plants healthy and well-maintained can help reduce the risk of infestation. Avoid overwatering and fertilizing, and remove any dead or dying leaves or stems.
How to Prevent Agave Snout Weevil Infestation
In addition to the control methods mentioned above, there are several things you can do to prevent agave snout weevil infestations:
- Inspect Plants Regularly: Regularly check your agave plants for signs of infestation. If you find any signs, take immediate action to control the weevils.
- Quarantine New Plants: If you’re bringing new agave plants into your garden, quarantine them for a period of time to ensure they’re not carrying any pests.
