Small Brown Beetles (In the House and Outside)

Little brown beetles may be a problem in your house and around your garden. Pantries are typically home to some kinds of little brown indoor beetles that crawl through dried grains, bore into furniture, and infest carpets.

Biscuit beetles and larder beetles are two common household small brown beetles that may be located in the kitchen. June beetles, brown click beetles, and European chafers can all damage your plants or lawns, so be on the lookout for them in gardens.

Because of their size, tiny brown beetles may be difficult to distinguish. Brown beetles may be as small as 0.082″ to 0.15″ (2 mm) in length, including some of the house’s tiniest brown beetles. Brown beetles, on the other hand, are bigger and may reach 0.78″ (20 mm) in length when found outdoors in your yard.

This article is meant to be a resource for identifying tiny brown beetles at home and in the yard. Knowing what kind of beetle you have discovered will be aided by descriptions and pictures of these tiny brown “bugs.”

Small Brown Beetle Facts

Common brown beetles have two antennae and an oval body with six legs. The insect order Coleoptera contains thousands of beetle species. Two sets of wings are protected by two wing covers in most adult beetles. Some tiny brown beetles may become a pest indoors, however not all brown beetles are pests.

Small Brown Beetle Identification

The body form, behavior, and habitat of tiny brown beetles can all be used to identify them. To help determine the species, look at whether the brown beetle has an oval or extended rounded body.

Moreover, some beetles have a huge, spherical head, but others have a tiny head and club-like antennae. The antennae can be used to identify the species of brown beetle. Several antenna designs, including serrated, segmented, and club-like antennas, are available.

Is there a long, unusual snout on the brown bug you saw in your house? The brown beetle is a kind of weevil in this instance. The elongated body and long projecting snout that Brown weevils employ to consume food differentiate them from other beetles.

Small Brown Beetles in the House

Finding little brown bugs in a package of flour or cereal can panic you. Brown beetles may be found throughout the house, however. Bedrooms, bathrooms, and living rooms may all be infested.

Carpets, soft upholstered furniture, medicine cabinets, and baking mixes are among the products that may contain them. If you’ve got a questions like, “What is that brown bug in my house?” then please read on to find out what type of brown beetle it is.

Biscuit Beetle (Stegobium paniceum)

The biscuit beetle is a common little brown beetle found in dry food items packets. It has a hard shell and is quite tiny. The brown, reddish color of the tiny brown biscuit beetle is cylindrical. These tiny brown insects, which are 0.86 to 0.13 inch (2.5 to 3.5 mm) long, Its club ends are three-segmented, making it easy to identify.

Drugstore beetles, biscuit weevils, and bread weevils are all names for Biscuit beetles. The habitat of Stegobium paniceum is the source of its common names. In flour, dry mixes, cookie jars, spices, and the medicine cabinet, you’ll frequently find the tiny brown biscuit beetle. Wool, leather, and hair are all edible to the beetles.

Cigarette beetles and biscuit beetles may be difficult to distinguish. The brown beetles have a similarly shaped body, apart from being tiny insects. Biscuit beetles, on the other hand, lack serrated antennae and have smooth wing coverings like cigarettes. Their wing covers are pitted and antennae are segmented, rather than smooth.

thankfully, it’s simple to keep biscuit beetles out of your foodstuffs. When bringing home groceries, be sure to check food packaging. Next, in air-tight containers, store grains, flour, and other dry foods. Finally, wrap any contaminated foods in thick plastic and trash them in the outdoor garbage if you notice them to be so.

It’s a smart move to clean up spilled goods and keep crumbs and other dried food particles under refrigerators, tables, and pantries.

Small Brown Beetle Identification: The rounded, cylindrical body of biscuit beetles, as well as their crimson-brown color and two antennae with three segments at the ends, distinguish them.

Varied Carpet Beetle (Anthrenus verbasci)

The varied carpet beetle eats natural fibers and has a mottled brown, white, and yellowish body. In comparison to its tiny head and shabby black antennae, the beetle’s body is like a rounded shield. From 0.07 to 0.14″ (1.7 to 3.5 mm), the carpet beetle has a wide variety of sizes.

Natural fibers are the preferred food of varied carpet beetles. Brown carpet beetles may infest carpets, textiles, and furniture in your home, causing damage. The larvae, not the adults, are more likely to cause destruction to soft furnishings. Tiny furry brown caterpillars measuring 0.2″ (5 mm) long are identified as varied carpet beetle larvae.

Small Brown Beetle Identification: Varied carpet beetles feature segmented antennae, six spindly legs, and a brownish mottled body with a round, almost spherical shape.

Larder Beetle (Dermestes lardarius)

The larder beetle has a six-legged body, two club antennae with segmented ends, and feeds on dried foods. 0.33 to 0.38 (83 to 95 mm) is the length of an adult larder beetle. A brownish band with six black dots on its back distinguishes the larder beetle.

Because of the frequent presence near foodstuffs, the larder beetle gets its name. Dry meats, cheeses, grains, and pet food are all eaten by the small black and brown larder beetle. Beetle larvae also created holes in wood and drywall, which you may discover.

All dry food items should be stored in closed containers to limit larder beetles. Also, securely seal trash cans and don’t leave pet food out overnight. Moisture bugs are another name for these bothersome beetles. As a result, preventing the beetles from entering your home may be aided by repairing leaking plumbing.

Small Brown Beetle Identification: The brown to tan band on the back of larder beetles has three black spots on either side and is easily recognizable. Club antennae and a black head distinguish the black and brown beetle.

Red Flour Beetle (Tribolium castaneum)

The red flour beetle is a reddish-brown beetles that can be found in dried foods and may be discovered in homes. The bodies of these little beetles are brown or rusty. The beetles are approximately 0.13″ (3.1 mm) long and have an apparent oval abdomen.

Their wings may also be used to travel short distances. If you observe tiny red flour beetles flying or crawling around, you may assume that you have them in your home.

Also, cereal boxes often have holes in them, and reddish-brown beetles can be found in flour and other cereals. To prevent attracting them, store dry food items in air-tight containers, as with other brown beetles in the home.

Small Brown Beetle Identification: The reddish-brown oval body of red flour beetles has three identifiable antennae and a three-segmented club end.

Furniture Beetle (Anobium punctatum)

The furniture beetle is a blackish-brown bug with six legs and causes damage to wood and household goods. They range in length from 2.7 to 4.5 mm. Brown beetle specimens have a dark body with ridges and dimples, as well as segmented antennae, according to images.

Adult furniture beetles, on the other hand, aren’t harmful. The larvae of furniture beetles cause the damage they do in the home. Furniture beetle larvae dig holes in wood by boring into it, as the name suggests. Furniture beetles and their larvae thrive in high air humidity and moist wood, which is typical.

Small Brown Beetle Identification: Furniture beetles have an ellipsoidal body and a dark brown color. The prothorax of the tiny beetles is like a monk’s cowl or hat, and it is noticeable.

Cigarette Beetle (Lasioderma serricorne)

A cigarette beetle has a rounded, oval body covered in fine hairs and is drawn to dried tobacco products and dry foodstuff. Little brown beetles, which may be found in dark corners, range from 0.78 to 0.11 inches (2 to 3 mm). Stored dry food products may also include these bothersome beetles.

The name “cigarette beetle” refers to their attraction to dry tobacco products. Drugstore beetles look a lot like oval brown beetles. These little brown insects, however, have serrated antennae rather than the club-like antennae of commercial beetles. The body of cigarette beetles is also smooth, not ridged.

Small Brown Beetle Identification: The brown, oval bodies of drugstore beetles; their tendency to conceal their head and legs while remaining motionless when startled; and their ability to stay still are all characteristics that distinguish them.

American Spider Beetle (Mezium americanum)

The American spider beetle is a reddish-brown bug with thin wing coverings, tan-colored slender legs, and segmented antennae that resembles a small spider. The little brown bug measures 1.5 to 3.3 mm in length (0.06 to 0.13 inches). Brown spider beetles have rounded abdomens that give them a spider- or mite-like appearance, which is a characteristic trait.

When they feed on stored foods in your pantry, brown American spider beetles can become a pantry pest. Seeds, spices, cereals, dried fruits, beans, and bread are all riddled with annoying bugs. Tobacco and cayenne pepper are also attractive to them. The best way to avoid American spider beetles getting into your bags of dried foods is to prevent them from entering in the first place.

Small Brown Beetle Identification: The body of American spider beetles is bulbous, glossy, and has six long light-brown legs. The head is tan in color.

Types of Small Brown Beetles

Ornamental plants, as well as their larvae, may be attacked by tiny brown beetles that can be found in yards and gardens.

June Beetles

Over 900 species of June beetles exist in the Phyllophaga genus, with some having a gleaming dark brown or reddish-brown coloration. Brown beetles, often known as June bugs, range in length from 0.47 to 1.38 inches (12 to 35 mm). The beetles have short antennae and a lustrous body with spiky legs.

Chafers are a type of adult June beetle. In the summer, brown June beetles can be found eating through deciduous leaves. Broadleaf trees, decorative shrubs, and flowering plants are all likely to have them. White grubs, which destroy plants, legumes, and turfgrass at the roots, are also beetle larvae.

Dull brown bodies with green stripes are seen on other types of June beetles in the genus Cotinis. However, the genus has a wide range of colors, with several beetles having electrifying green exoskeletons.

Small Brown Beetle Identification: The body of the Brown June beetle is metallic red, with jagged-looking spines on six legs and short antennae.

Rice Weevil (Sitophilus oryzae)

The rice weevil is a little brown insect with an extended oval body and a characteristic snout that is elongated. The body of the dark, orangey-brown butterfly has distinctive markings on its wing covers. The unusual bug is 0.11 to 0.17 inches (3 to 4.5 mm) long, depending on the specimen. Maize weevils are the destructive pests that resemble them.

One of the most serious grain pests globally is rice weevils, according to experts. Brown bugs can fly from one place to the next and attack stored grains and cereals. The nasty brown insects develop into brown weevils after laying eggs in dry food items.

Small Brown Beetle Identification: On their hard protective wing coverings, rice weevils have distinct yellow or reddish markings. The head has a long snout and the prothorax has a distinctive pitted look.

Click Beetles (Elateridae)

Denticollis linearis (pictured) is a little brown beetle belonging to the Elateridae family of click beetles. Black or brown click beetles, which are less than 0.78 (20 mm) long, abound in nature. The body of click beetles is elongated, and the head is joined. A black band runs down the middle of the glossy brown body.

You seldom see adult click beetles during the day because they are nocturnal. Most Elateroidea species have serrated antennae, head and back markings, and the ability to “click” themselves into the air, despite minor color variation between them.

Small Brown Beetle Identification: The slender, extended, lustrous brown body of click beetles, as well as the black markings on their wing covers and the audible clack sound they make.

Asiatic Garden Beetle (Maladera castanea)

The Asiatic garden beetle is a winged bug with a cinnamon-brown body that resembles a tiny coffee bean. It causes damage to garden plants. When attracted to lights, these brown flying beetles grow to 0.37 inch (9 mm). During the night, the pesky flying beetles get inside by breaking through poorly-sealed doors and windows.

Brown beetles are more of a household annoyance than a serious threat. When feeding on geranium, rose, chrysanthemum, and aster leaves and flowers, however, the plant-destroying bugs may cause damage in your yard. In addition, brown patches on lawns may result from white grubs that live in the soil.

Small Brown Beetle Identification: Brown flying beetles with cylindrical bodies, spiky antennae, and six spiny legs are known as asiatic garden beetles.

European Chafer (Amphimallon majale)

The European chafer is a tiny beetle with a light reddish-brown oval body, light brown spiny legs, and prothorax that is active in late spring and summer. You may see light-yellow tufts of hair on the body of this brown beetle when you look at close-up pictures of it. Brown beetles range in length from 0.5 to 0.55 inch (13 to 14 mm).

In the summer, swarms of flying brown beetles known as European chafers can be seen. These are active in late spring and summer. Shrubs and low trees are where you’ll find them. The corpses of dead brown chafers may also be seen beneath the trees.

The larvae activity, not the adults, are to blame for the damage done by European chafers in your garden. The roots of trees, shrubs, and lawn grass are consumed by the big white C-shaped grubs when they hatch in the earth. Patches of grass become brown as a result of white grubs. Wildlife digging up the larvae foraging on lawns does even more damage.

Small Brown Beetle Identification: The oval brown body and grooves on the wing covers of European chafers distinguish them. It has two lamellate antennae and legs with jaggy spines.

Synchroa Bark Beetle (Synchroa punctata)

The synchroa bark beetle may harm trees by eating their bark, which is dark brown or black in color. The wing covers of the elongated, bullet-shaped, flattened dark brown beetle have thin lines. In addition, the beetle possesses long antennae. 0.27 to 0.51 inch (7 to 13 mm) long, brown synchroa bark beetles Bark beetles may kill weakened trees by severely damaging them.

The brown bark beetles may remove nutrients and water from twigs and branches by feeding and reproducing beneath the tree’s bark. Little holes and tube lines on the trunk or limbs are signs of synchroa bark beetles.

Small Brown Beetle Identification: The body of the synchroa bark beetle is long and slender, with a dark brown color.
