Larder beetle infestation

Larder beetle SPI

The Larder beetle (Dermestes lardarius) is from the family of the Dermestidae. All representatives of this family feed primarily on various dried meats, dried fish and remains from animals but in some cases they can also feed on dried plants. This is why they can be found in places such as behind and under cookers and refrigerators in domestic premises and in businesses such as delicatessen stores, fishmongers, meat processing plants, and butchers.

The Larder beetle is considered a pest, due to the fact that it infests dried meats, fish and plants and also causes damage to timber, lead, tin and other materials during its development cycle. The larvae bores into them for pupation purposes and creates holes in the material, which may sometimes be a costly damage.

The signs of a Larder beetle infestation are damage in timber, cork and insulation, as well as in foods like various meat products (bacon, ham, salami, etc…), cheese, dried fish, pet food, tobacco, etc… The damage is caused by the larvae of the Larder beetle that looks for a safe place to continue its life cycle and pupate, invading the above-mentioned foodstuffs.

About Larder beetles

The Larder Beetle or the Bacon beetle, which is another name for the same pest, is often found in domestic premises, usually in the areas where dried meat, fish, tobacco products, and spices are kept. It is also found in commercial and industrial businesses handling those products.

Indoors, the breeding of the Larder beetles can be a continuous process, regardless of the weather conditions outside. Once an adult Larder beetle gets in contact with a product it lays eggs in close proximity with it and the life cycle of the new beetles starts. The female beetle lays a total of approximately 200 eggs. When the eggs of the Larder beetle hatch, the larvae comes out. It usually takes 5 to 6 moultings before the larvae pupates. This happens for a period of 35 – 80 days until the pupation begins. It is in the end of the larval period when the larvae can be seen by people as they start migrating and looking for solid places (lead, cork, insulation or wood) where they can pupate. The Larder beetle remains in this form for about 15 days before reaching maturity and starting the cycle again.

The Larder beetle has dark brown colour and is 8 – 9 mm long. Its wings are covered with hairs that are pale yellow. The bottom part of the beetle is also covered with hairs in the same colour.
