Frequently Asked Questions
In common language, they are often used interchangeably. However, in precise entomology, 'bean weevil' (Acanthoscelides obtectus) is a specific species of seed beetle, which is a type of beetle, not a true weevil. True weevils belong to a different family (Curculionidae).
Yes, but indirectly. They infest stored, dry legumes like beans, lentils, or peas. If you have pantry stocks of these, an infestation can start there. They do not bite or damage household structures.
Look for small, round exit holes in the beans (about 1-2 mm), a fine dust-like frass (insect waste) around the beans, or the presence of small, oval, brownish adult beetles near your stored legumes.
No, they are not poisonous and do not bite. However, they contaminate food, making it unfit for consumption due to the larvae and waste inside the beans. Infested beans should be discarded.
