The following are descriptions and photographs of common flying house beetles. Similar to killing all kinds of panty bugs, grain beetle eradication is also required. Cereals, pastas, chocolate, almonds, and cake mixes are the most common. After that, you should clean any areas where grain beetles were active.

iii. Presence of Other Bugs

This easy-to-identify garden beetle has a flattened shape and measures 0.79” to 2” (20 – 25 mm). There are also color variations with this beetle species, with some having red wing cases with complex black patterns. The black and yellow longhorn beetle is a medium-sized beetle with recognizable black markings on its yellow elytra. The yellow and black beetle has a slender abdomen tapering to a point. The beetle also has black-banded yellow legs and black and yellow striped antennae. The red-headed cardinal beetle is a species of fire-colored beetle.

Black and Red Blister Beetle (Megetra cancellata)

The drugstore beetle is a common sight in kitchen packets of dried meal items with a hard shell. A fuzzy reddish-brown body with grooved and pitted wing covers is seen in photographs of the little house beetle. The average length of a drugstore beetle is 0.08 to 0.13 inches (2.25 to 3.5 mm). Grain beetles have a long, flattened oval body with large eyes and two segmented antennae. Oryzaephilus surinamensis (top) and Oryzaephilus mercator (bottom) are close-up pictures of grain beetles.

Varied Carpet Beetle (Anthrenus verbasci)

The tiny black beetle also has two black antennae and 6 red and black legs. These shiny black beetles have a short oval body without any significant markings. The underside of these small black “bugs” reveals rusty brown markings that help distinguish it from other beetles.

Small Brown Beetles in the House

For this reason, they are also called glowworms in some countries. Looking at pictures of a tiger beetle, it can be easy to mistake this for a completely different species of insect. Tiger beetles have long skinny legs, long antennae, and curved mandibles. Eradicating granary, rice, and maize weevils is the same for any type of pantry bug.

Sometimes even the exit holes are big enough to identify the damage. The adults lay eggs in the cracks of the wood of the host plants. An unusual feature of red milkweed beetles is the shrill noise they make when startled and a purring noise when interacting with other beetles.

Also called the wheat weevil, a granary weevil measures 0.12” to 0.20” (3 – 5 mm) long. The flightless creatures are typically found in stored grains in a pantry. You may see signs of these annoying black “bugs” in packets of rice, corn, oats, barley, rye, millet, sorghum, and wheat. To control the little black beetles in the house, it’s crucial to ensure foodstuffs aren’t left out, including pet food. Additionally, you should caulk all cracks and screen openings to prevent the small beetles from getting indoors.

Spotted Yellow Cucumber Beetle (Diabrotica undecimpunctata)

Beetles in the home may cause contamination of meals, upholstery, and carpets, as well as being a real nuisance. It is important to know how to distinguish between house beetles and other insects. Although dull black with faint white spots is its typical coloration, the slender beetle can also have iridescent green or bronze colors. The thin legs can also have fine setae covering the upper sections. Some beetles in the family Chrysomelidae have striking yellow and black markings and are crop pests. Many people refer to any type of creepy-crawlies in the home as “bugs.” However, in the true sense of the word, beetles aren’t bugs.

The desert blister beetle is identified by its bright reddish-orange head, thorax, legs, and shiny black abdomen. The small shiny red beetle measures 0.23” to 0.27” (6 – 7 mm) long. Its common and scientific names come from the scrawly black markings on the crimson red wing covers. Identifying red beetles can be challenging because most of them are tiny creatures, and they scurry away fast.

Although commonly called ‘ladybugs,’ these delightful winged insects are a type of beetle in the family Coccinellidae. The term ‘lady beetles’ is the more correct name for these red beetles with black spots. Species of ladybugs (or, ladybirds) are beneficial beetles that are good for controlling aphid populations. Soldier beetles from the family Cantharidae have long straight bodies without any curvature.

The green scarab beetle is an oval-shaped emerald-green beetle with a distinguishing black mark at the base of each wing cover. The shiny green beetle has short, clubbed antennae, green legs, and a tiny green head. As their name suggests, granary weevils are found in dried foodstuffs. The reddish-brown or black beetle can live in packets of cereals, oats, rice, flour, and wheat.

For example, beetles are a type of insect in the order Coleoptera. This article will refer to all types of insect pests as bugs—regardless of whether they are true bugs or not. Another type of carpet beetle is the black carpet beetle (Attagenus unicolor). Instead, the pesky white larvae can eat holes in soft upholstery, carpets, and fabric. Fleas are microscopic brownish bugs that can jump from host to host, spreading disease and infections. These household bugs have oval body and long legs, and the jumping bug is the size of a pinhead, between 0.04” and 0.13” (0.1 – 0.3 mm).

Other identifiable features of weevils are their elbowed antennae, and some have hairy tufts on their oval backs. The common cardinal beetle is a small red beetle measuring 0.8” (20 mm) long and has red elytra, thorax, and head. Red-headed cardinal beetles have spindly black legs and long, toothed, or comb-like antennae.

The dark brown, reddish-brown, or blackish-brown pest grows about 0.13” (3.2 mm) long. Junk bugs are weird brown bugs with triangular bodies, yellow markings, and brown heads. The brown bug-like larvae have horn-like mouth-parts that they use to kill prey. However, their sharp jaws can also inflict a nasty bite, cause skin redness and swelling. Carpet beetles are identified as tiny house bugs with mottled yellowish and white patches on their wing coverings.

Unless you see beetles or fresh wood powder around the holes, chemical treatment is not necessary. Fresh wood powder is usually light in color and does not clump. They are brownish black in color, with many gray hairs on the head and forepart of the body. The segment just behind the head has a shiny raised bump on each side, giving it the appearance of a face. European chafers are identifiable in the summer as swarms of flying brown beetles that are active in late spring and summer. You may also notice the carcasses of dead brown chafers under the trees.
