Merchant Grain Beetle Beetles

Elimination

The first step is to identify and dispose of infested containers. As pet food can also be attacked by these insects, it will require great attention. Subsequently, it would be appropriate to place in airtight containers the products that have not yet been affected. In this way, contamination of unaffected foodstuffs is avoided.

Next, it is advisable to vacuum the cracks and crevices in the pantry to remove any food residues or insects that may be present. Move the household appliances in order to vacuum them behind. To avoid a second infestation, the contents of the vacuum must be emptied into the bin, as the multiplication of insects could still continue there.

Finally, if the situation persists, the intervention of our certified technicians remains a safe and effective solution. An intervention implies that the treated surfaces should not be washed for about a month in order to allow the product to work effectively.

Before any intervention, all equipment must be removed from the pantry. Subsequently, it is strongly suggested to place sheets of paper on the shelves before replacing the food in order to prevent the containers from coming into contact with treated surfaces.

Description and development

The Merchant Grain Beetle (Oryzaephilus Mercator ) and Sawthoothed Grain Beetle (Oryzaephilus surinamensis ) are small rusty brown beetles. They are about 3 mm long and have six sawtooth-like bumps on each side of the thorax.

The female can lay 50 to 300 eggs, which she puts in cracks where food is present. The larvae will emerge 3 to 17 days later. The life cycle lasts three to ten weeks, depending on environmental conditions.

Habits

These beetles are often found in grocery stores and private homes. Their flat body shape lets them slip readily into food product packaging. They can chew through paper and cellophane. They live off cereals, grains, flour, cookies, soup and cake mixes, spices, pasta, and other similar foodstuffs.

Tips

Once the problem is solved, it is a good idea to seal all cupboard cracks and openings with an appropriate sealant. It is also strongly recommended that you store all foods at risk of contamination in airtight containers as soon as you bring them home, which will at least limit the damage in case of a new infestation.
