Biscuit
Beetle
The
Biscuit beetle (
Stegobium
paniceum), also known as the
Drugstore
beetle, Bread beetle or
Biscuit
beetle, is a tiny, brown beetle that can be found infesting a
wide variety of products, and is among the most common non-weevils to
be found there. It is the only member of the
monotypic genus
Stegobium.
They have a worldwide distribution and can
be more commonly found in
warmer climates. They are similar in appearance to the Cigarette beetle
(Lasioderma serricorne),
but are slightly larger (adults can be up to 3.5 mm in
length).
Additionally, Drugstore beetles have antennae ending in 3-segmented
clubs, while Cigarette beetles have serrated antennae (notched like
teeth of a saw). The Drugstore beetle also has grooves running
longitudinally along the elytra,
whereas the Cigarette beetle is smooth.
Their larvae are small, white grubs, and
they can be distinguished
from the grubs of the Cigarette beetle by their shorter hair. The
female can lay up to 75 eggs at once, and the larval period lasts up to
several months depending on the food source. It is the larvae that are
responsible for most of the damage that this species can cause.
As their name suggests, Drugstore beetles
have a tendency to feed on
pharmacological products, including prescription drugs. They will also
feed on a diverse range of dried foods and spices, as well as hair,
leather, books, and museum specimens. They can bore into furniture, and
in some cases tin foil or sheets of lead.
The most effective method of ridding your
home of these pests is to try and discover the source of the
infestation.
Once this has been found, efforts can be
made in removing the root of the problem, which is usually related to
bird nests,
food and high humidity levels. Therefore steps will have to be taken in
removing any birds nest from the premises (if this is the situation
then ideally specialist advice should be sought), food residues and any
food which has been left open; these steps should be followed by
adopting measures to decrease the humidity levels; perhaps by way of a
dehumidifier.
Once satisfaction has been reached in
removing the main cause of the
infestation, the immediate area of the outbreak should be cleaned
thoroughly with a vacuum cleaner, paying special attention to small
cracks and crevasses; ideally the area should be treated with an
effective insecticide, too.
