The larvae are nocturnal, hatching the spring, and can be found under rocks, bark, and in leaf litter. It takes approximately one year for the larvae to emerge as adults. They have rounded bodies with fine scales on the pronotum and elytra in various colors. The white scales are on the lateral margins of the pronotum and the elytra.

You’ll often find them under leaves, stones, and scurrying around open woodlands. They are attracted to lights and can become a nuisance pest indoors. The common cardinal beetle is often confused with the black-headed cardinal or scarce cardinal beetle. Both are species of red beetle, but they have black heads. These red beetles can be beneficial insects because they feed on small insects and larvae. However, most people refer to any small pesky critters with legs as bugs, whether tiny beetles, caterpillars, spiders, ants, flies, or ticks.
Brown Leather Wing Beetle
Larder beetles are oval-shaped insects that feed on dried foodstuffs and are a household beetle pest. The wing covers of the little beetles are brownish to black, with a tan or yellowish band. In the light-colored band, there are also black patches. Larder beetles range in size from 0.33 to 0.37 inch (8 to 9.5 mm). Processed foods in your pantry are infested with larder beetles.
Red Net-winged Beetle
The beetles also commonly live on oak, poplar, willow, ash, and beech trees. The red-headed cardinal beetle is a species of fire-colored beetle. Its elongated oval shape and vibrant color make the beetle easy to spot on vegetation. You will often find it when it’s most active in summer, scurrying over tree and shrub foliage in woodlands and parks. There is a wide variation in the different species of Hercules beetles.

Wood infesting beetles
Identify the beetle type and tailor your approach to cut a beetle infestation. Use natural repellents like diatomaceous earth and essential oils to keep your home clean. Anobiids have a singular focus on wood, sparing stored food. Their preferred habitats are places with high humidity or dampness. As such, they are commonly found in unheated buildings, basements, crawl spaces, and garages. Each group of wood-boring beetles boasts several species, all adept at wood consumption.
Pedunculate Ground Beetles (Scarites spp.)
Stag beetles are enormous black insects measuring around 2.3” (60 mm). Also called the elk beetle, the characteristic feature of the hard-shelled beetle is its powerful antler-like jaws with forked teeth. Some stag beetles appear reddish-brown rather than shiny black.
Ten-lined June Beetles (Brown Type of Beetle)
Identifying features of this large black beetle are rusty-colored spots on its ridged wing covers. Additionally, the large beetle has large jaws it uses to catch and devour its prey. 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.
There is a black band across the base of the head in the males and a pale band between the eyes. The Coyote Brush Leaf Beetle (Trirhabda flavolimbata) is found along the coast of the San Francisco Bay area. The Bronze Beetle (Chrysolina bankii) is a leaf beetle species native to Europe and the western Mediterranean Basin. It has been introduced to the United States with an expanding range, that includes California. The Woolly Darkling Beetle (Eleodes osculans) is a ground beetle and is common in coastal southern and central California.
Flour Beetles
The nasty brown insects also lay eggs in dried food products, where they pupate and develop into brown weevils. Opening a packet of flour or cereal to find tiny brown bugs can send you into a panic. However, you could notice brown beetles anywhere in the home. In addition, you may find them in carpets, soft upholstered furniture, drug cabinets, or baking mixes.
Getting rid of cockroaches is vital because they spread disease and contaminate food. Beetles can infest areas with food, habitats, entry points, light, moisture, and infested items. To solve the problem, first, figure out what kind of beetle it is. Then, close off any openings where they can get in and keep food stored away.
Known as “silent killers,” termites can work to actively damage your home without you even knowing you are infested. Bed bugs can enter your home by attaching on to your luggage or clothing when you travel or come in on used furniture you purchase secondhand. If you have bed bugs, you may wake up with small, red, itchy bumps or notice an offensive musty smell that you are unable to identify. When checking for bed bugs, look for small brown to reddish spots on your bedding that can come from fecal matter or blood. Examining the creases of your mattress may reveal small bugs.
The small brown beetles measure between 0.07” to 0.11” (2 – 3 mm). Flour beetles get into homes in dried grain products, especially flour. Signs of flour beetles are small white worms in grains, flour, pasta, dried legumes, and nuts. The best way to get rid of and prevent furniture beetles is to reduce humidity indoors.
Pantry bugs are difficult to see since they prefer damp, moist places and are most active at night. The rusty-brown insects range in size from 0.12 to 0.18 inches (3 to 5 mm). Soldier beetles measure about ½ inch long and have a black head and black wings with yellow, light orange, or tan wing covers.
The small reddish-brown or brownish-black beetles tunnel into wood, weakening structures and creating tiny holes. The small, destructive pests measure 0.12” to 0.25” (3 – 6 mm) long. The small shiny brown beetles have a slender oval body and rounded thorax.
These small pests feed on your cats or dogs and, if left uncontrolled, can lead to hair loss, skin infections, anxiety, and anemia. While fleas prefer animals because they have a lot of furs to hide in, they can bite humans. When they bite and suck your blood, they also secrete saliva into your bloodstream. This saliva contains allergens that can cause itching and, in some cases, a more severe allergic reaction that can cause shortness of breath.
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. The wood-infesting anobiids range from 1/8 to 1/4 inch in length. The body segment just behind the head is hoodlike and completely covers the head when the insect is viewed from above. Similar to killing all kinds of panty bugs, grain beetle eradication is also required.
