Agave Weevils Information
Agave weevils, also known as agave snout weevils, are a type of insect that feeds on agave plants.
- They belong to the snout beetle family.
- They are known for their long snout-like beak, which they use to bore into the stem or base of agave plants to feed on the sap and tissues.
- Agave weevils are native to Mexico but have spread to other parts of the world, including the United States.
- These pests can cause significant damage to agave plants, especially in cultivation. The larvae of the agave weevils feed on the roots of the plants, causing additional damage and weakening the plant, making it more susceptible to disease and other pests.

Damage Caused by Agave Weevil
The Agave snout weevil, also known as the agave weevil, is a destructive pest that feeds on agave plants, causing significant damage. These weevils bore into the base of the plant and feed on the sap and tissues, which can lead to wilting, yellowing, and eventual death of the plant.
In addition, the larvae of the agave snout weevil feed on the plant’s roots, further weakening the plant and making it more susceptible to disease and other pests. The damage caused by agave snout weevils can seriously impact both ornamental and commercial agave plant populations. Thus, it is essential to prevent and control this pest.

How Do Agave Weevils Work?
Agave Weevils work in this way:
- Female weevils lay their eggs in the base of the agave plant.
- Then, the eggs hatch into larvae, which feed on the plant’s roots, causing additional damage.
- The adult weevils use their long snout-like proboscis to feed on the sap and tissues. This feeding activity causes wilting, yellowing, and eventual death of the plant.
- The adult weevils also mate and lay eggs in the same area, leading to a cycle of damage to the agave plant.
- This feeding and reproductive activity can significantly impact both ornamental and commercial agave plant populations, leading to significant yield losses and reduced plant health.
Therefore, it is crucial to prevent and control the agave snout weevil to protect agave plants from this destructive pest.

How to Get Rid of Agave Weevils
1. Keep Your Agave Plants Healthy
You can remove and dispose of infected Agave plants to reduce the population of agave weevils. Keep them healthy and well-maintained to reduce their susceptibility to weevil damage.
2. Invite Birds to your Garden
Introducing natural predators to your Garden is an effective way to control agave weevils. Some birds, like Woodpeckers, Wrens, Nuthatches, and Bluebirds, feed on these stubborn pests.
Even parasitic wasps feast on the eggs and larvae of the Agave Weevils and help to eliminate the population.
You can build nesting sites and birdhouses to encourage these friends to live in your Garden and help you to get rid of Agave Weevils.

3. Apply Neem Oil
Apply neem oil to Agave plants to minimize the use of harmful chemicals. Use 5-10 drops of neem oil to 100-200 ml of water and pour it into a spray bottle. Shake well and apply at the stems and base of the plants; make sure you cover the area thoroughly.
You should pay extra attention to the spaces where the weevils hide and lay eggs. Repeat the application if needed.
4. Go Organic
Spinosad is an organic insecticide that is effective against Agave Weevils. Buy Spinosad products that mention their use to kill Agave Weevils. Read the label to mix the Spinosad according to the instructions.
Ensure that you measure carefully and mix it thoroughly. Apply to the stems and base of the plant and repeat if necessary.
5. Use Insecticides
Apply insecticides specifically meant to destroy Agave Weevils to the base and stems of the Agave plants to kill them. Follow the instructions carefully to avoid damaging the plants or harming non-target species.
Repeat if required, and be careful with the use as it can be toxic to humans and pets.
6. Remove Manually
You should inspect your plants regularly and remove any adults or their larvae that you find manually. You can also place sticky barriers around the base of the agave plants to prevent adult weevils from reaching the plants.

7. Choose Cultivars Less Appealing to Snout Weevils
You can prevent Agave Weevil attacks by planting agave cultivars unattractive to the pests. It has been observed that these pests find Agave Attenuata species tough to pierce.
8. Create a Barrier
You should cover the surrounding base of the plants using barriers such as sand, gravel, or mesh to prevent the weevils from reaching the leaves.

9. Solarize the Soil
Try covering the soil around the plant using clear plastic for 2-4 weeks in the summer to solarize the soil. This can help kill the weevils and their eggs.
10. Use Essential Oils
You can also mix essential oils such as rosemary, eucalyptus, or peppermint with water in equal proportions and spray the mixture on the plants. Such oils can help repel weevils.
11. Encourage Bat Populations
Bats are natural predators of many insect pests, including agave weevils. You can encourage bat populations in your area by providing them with suitable roosting places and by planting native trees and flowers that they feed on.
12. Use Diatomaceous Earth
Diatomaceous earth is a natural, abrasive powder that can kill agave weevils by drying out their exoskeleton. Sprinkle a thin layer of diatomaceous earth around the base of the agave plants.

13. Rotate Crops
You can also consider rotating your agave crops to different garden areas each year. This can help break the life cycle of the weevils and reduce their populations.
14. Natural Repellents
Mix a solution of garlic, onion, and hot pepper with water and spray it on the Agave plants. This can help repel the Weevils and prevent them from feeding on the plants.
15. Use Decoys
Additionally, try to place artificial or decoy Agave plants near the real ones. The Weevils will be attracted to the baits and feed on them, which can save the natural plants.
