About Bean weevils
Bean beetles, also known as seed beetles or bean weevils, are small insects from the Chrysomelidae family that infest beans and other legumes. They can cause significant damage to stored beans by consuming both the beans and their larvae.
Adult bean weevils are 2 to 4 millimeters long, brown or gray in color, and lay eggs on the outside of beans. The hatched larvae tunnel into the beans to feed, reducing both quantity and quality.
Effective management involves proper storage techniques, like using sealed containers, and may require insecticides or fumigation for severe infestations. Regular monitoring of stored beans is essential to quickly address any signs of infestation.
How to Identify Bean Weevils ?
The initial step in protecting your pantry goods from these small intruders is recognizing bean weevils.

Their slim physiques and unique patterns distinguish them from other pests commonly found in pantries.
Examine your beans thoroughly for any indication of pest presence. Search for small openings in the beans’ exterior, which signal the locations where the adult weevils have deposited their eggs. You might also notice small larvae moving around inside the beans, which is a definite indication of a problem.
Be alert and respond quickly at the first sight of bean weevil presence. With the knowledge of what to watch for, you can safeguard your pantry and prevent these bothersome pests.

- Contamination occurs when beans that are infested can spread to other stored beans, resulting in additional financial losses.
- Population Explosion: Bean weevil populations can quickly grow without any interference, making the infestation worse.
Controlling Bean Weevil Infestations:
- Cultural Practices:
- Rotate bean crops with non-legume crops to disrupt the bean weevil life cycle.
- Properly dispose of infested beans and debris to prevent re-infestation.
- Physical Control:
- Use pheromone traps to monitor and capture adult bean weevils.
- Handpick adult weevils and remove infested beans.
- Chemical Control:
- Apply insecticides labeled for use on beans according to recommended guidelines.
- Use insecticidal dust or sprays in storage areas to kill adult weevils and larvae.
