The rice weevil and granary weevil are pests of stored grain and seeds. They
develop inside whole grain kernels as small, white, wrinkled, grub-like larvae.
There is generally no external evidence that the larvae have been eating and
growing inside the seed until after about one month when the adult weevil
chews through the seed coat and emerges. The adult weevils are 1/8th inch
long and have slender, hard-shelled bodies that appear pitted or scarred with
tiny holes. They are brown to reddish brown in color. The rice weevil has four
faint yellowish spots on the back of the abdomen. The granary weevil is
uniformly colored with no spots.
Presence of rice or granary weevils inside the home usually indicates there is
infested whole grain or seeds. This may be food seeds or beans in the
cupboards, popcorn, saved garden seeds, dried seed decorations, decorative
Indian corn, "bean bags," old grain-based mouse bait, or other stored seeds.
Rice and granary weevils are harmless to people, houses, furniture, clothing
and pets. They cannot bite or sting and they do not carry diseases. They will
not feed on furniture, the house structure or other items. The harm they do is
destruction of the seeds they infest and the annoyance of being in the wrong

the solid heartwood which isn't as nutritious as
live trees. They may also stay in the wood after
harvest, becoming a part of a wall or furniture.
This beetle also has one of the longest life
cycles documented. It usually goes from egg to
adult in about 2 years, but has emerged from
flooring, beams and furniture as long as 10 to 15
after the materials were manufactured.
