In reality, weevils are beetles. This family contains more species than any other group of beetles. They tend to be slender or oval-shaped insects. Weevils can range in size from less than 3 mm to over 10 mm, depending on the species.
Weevils can kill garden plants outdoors. Indoors, the pests cause more trouble than harm. They cause more damage to food that they eat by contaminating it with feces and cast skin.
