The drugstore beetle and cigarette beetle are in the same family, and look very similar. Drugstore beetles are also very small insects, measuring 2 to 3.5 mm they plague businesses by feeding on flour, spices, cereals and other dried stored foods.

There are several species of flour beetles, but they all have one thing in common: they are attracted by flour, pet foods, and cereal products. Flour beetles are common in big warehouses and storage facilities across the world and are often found in groups close to their food sources. They are small, tubular, reddish insects measuring 3 to 4 mm. Flour beetles are particularly destructive because they give the flour a strange colour and bad odour.

The most destructive, of all warehouse pests are the warehouse beetles. These small, oval-shaped insects can wreak havoc and damage numerous products such as nuts, dried pet food, barley, legumes, seeds, wheat, and more.

There are various species of weevils of varying shapes, sizes, and colours. Weevils can always be identified by the shape of their heads: adult weevils feature a snout-like head, with an elongated tip that can be as long as their bodies.

Indian meal moths are one of the most common warehouse pests. They attack a large variety of goods, including birdseed, dried pet food, bread, dried soup mixtures, pasta, flour, and spices — just to name a few. Adults can be found far away from their food source, so they are often misidentified as clothing pests rather than warehouse pests.
