Weevils/Beetles McGrath Pest Control
stored grain weevel
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

To the left is the Ivory-marked Borer Beetle.  It
feeds on leaves and twigs and their eggs are laid
in the cracks of dead trees.  Their lavae bore
into 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
