Rice weevils are described as one of the most serious grain pests globally. The brown bugs attack stored grains and cereals, and they can fly to new locations. The nasty brown insects also lay eggs in dried food products, where they pupate and develop into brown weevils. The red flour beetle is another type of beetle that can invade homes and live in foodstuffs.

Common Furniture Beetle (Anobium punctatum)

You also may hear a hissing noise from them if they feel threatened. Insects in the beetle order can range in size from very small to relatively large. The smallest species of beetle is also the smallest insect in the world. The largest beetle, the Titan beetle, can grow to nearly 7” (17 cm)! However, the average size of most beetles is under 1” (2.5 cm) long.

Spotted Yellow Cucumber Beetle (Diabrotica undecimpunctata)

Processed foods in your pantry are infested with larder beetles. They look in dark places like kitchen cabinets for foods such as cured meat, cheese, and pet food. Furs, feathers, insects, and dead animals may all be eaten by dark-colored beetles. Common brown beetles are insects with six legs, two antennae, and an oval body. There are thousands of beetle species, all in the insect order Coleoptera.

The bug-like beetles usually have a thin covering of soil on their backs. There are thousands of species of ground beetles that belong to the family Carabidae. One of the most striking of the ground beetles is the golden ground beetle (Carabus auratus). This has an iridescent shiny green body with an almost mirror-like sheen. What do mysterious pinholes in wood flooring, furniture, or trim; damaged carpets and fabric; and discolored or foul smelling flour have in common?

The carabid beetles generally are found in grasslands, under rocks, or debris, especially in damp, boggy environments. The eastern-eyed click beetle has a distinctive slender black body covered in white speckles. The unusual feature of this long black beetle is the two large spots on its head that look like large eyes.

Active in spring and summer, you’ll find the large black beetles under logs, mulch, stones, and leaf litter. They feed on larvae, bugs, and small insects using their large pincers. The clay-colored billbug is a distinctive beetle species with gray and tan striped wing covers, thorax, and a long snout. The beetle’s curved beak is characteristic of all types of weevils.

Dry cereals, grains, and legumes should first be stored in air-tight and sealable containers. After that, any contaminated items must be destroyed or thrown away. Finally, before disinfecting all surfaces, vacuum the insides of cabinets. Because of their humpbacked look and lustrous, crimson-brown color, spider beetles are simple to identify.

Instead, their wing covers have a pitted appearance and segmented antennae. The biscuit beetle is one of the most common small brown beetles you will find in the house. The tiny brown biscuit beetle has a cylindrical body and brown, reddish color. These tiny brown insects measure 0.86” to 0.13” (2.5 to 3.5 mm) long. Furrier legs, antennae, and heads are also common characteristics of tiny beetles. Pantry bugs are difficult to see since they prefer damp, moist places and are most active at night.

Also called pincher bugs, the pesky insects with their brownish bodies measure 0.4” to 0.55” (10 – 14 mm) in length. Also, where you find the bug in your house can be a clue to its identity. For example, black drain flies, fruit flies, and houseflies are attracted to rotten foodstuffs. But you might find tiny black beetles in stored grains and other dried food products. The spotted red milkweed beetle is easily identified by its bright red wing covers, thorax, and head with tiny black dots.
