What are Agave Weevils?

Agave weevils are small, black insects that feed on and damage agave plants. They are most commonly found in the southwestern United States, but they can also be found in other parts of the world. Agave weevils can seriously damage and even kill an agave plant if they are not dealt with quickly and properly.

Identifying Agave Weevils

Agave weevils are relatively small, about the size of a grain of rice. They are black in color and have long, thin antennae. They can be found on the leaves, stems, and flowers of agave plants. They can also be found in the soil near the plant, where they lay their eggs.

Signs of Agave Weevil Damage

Agave weevils can cause serious damage to an agave plant. The signs of agave weevil damage include discoloration of the leaves, wilting of the plant, and visible holes in the leaves. They can also cause the plant to die off completely if the infestation is not treated.

Preventing Agave Weevil Infestations

The best way to prevent agave weevil infestations is to keep the area around your agave plants free of weeds and other debris. This will make it harder for the weevils to find a place to hide and lay their eggs. In addition, you should also inspect your agave plants regularly for signs of infestation.

Treating Agave Weevil Infestations

If you do find an infestation of agave weevils, it’s important to take steps to get rid of them quickly. One way to do this is to use an insecticidal soap or horticultural oil to kill the weevils. You can also use a natural insecticide, such as diatomaceous earth, to help control the infestation.

Cultural Control Methods

Cultural control methods can also be used to help get rid of agave weevils. For example, you can remove any infested leaves or stems from the plant and dispose of them far away from your other agave plants. In addition, you can also prune the plant to help reduce the number of weevils on it.

Other Control Methods

If the infestation is particularly bad, you may need to use chemical insecticides to get rid of the agave weevils. There are a variety of products available, and it’s important to choose the one that’s best for your particular situation. Be sure to follow all label instructions carefully.

Long Term Control

In order to prevent future infestations of agave weevils, it’s important to practice good cultural control methods. This includes keeping the area around your agave plants clean and free of weeds and debris, as well as regularly inspecting your plants for signs of infestation.


Agave weevils are small, black insects that can cause serious damage to agave plants. In order to get rid of them, it’s important to identify them, use insecticidal soaps or horticultural oils, practice cultural control methods, and use chemical insecticides if necessary.
