9 Tiny Brown Bugs That Might Be in Your Home

1. Drugstore Beetles

drugstore beetles

Identification: Drugstore beetles, also known as cigarette beetles, are small, brown, stored product pests. They have a rounded shape with hard wing covers.

Drugstore beetles are most commonly found in areas where food is stored. This includes kitchens, pantries, and places where food is kept in large quantities, such as grocery stores or warehouses.

They are particularly attracted to flour, cereals, spices, and other dry food items.

Health Risks: While drugstore beetles don’t pose significant health threats and are not known to spread diseases, they can contaminate dry foods, rendering them unfit for consumption.

Extermination: Keep pantries clean, discard contaminated food, and use pheromone traps to get rid of drugstore beetles.

2. Silverfish


Identification: Silverfish are shiny, silver or brown, teardrop-shaped insects.

Silverfish are most commonly found in humid, moist environments. They thrive in areas such as bathrooms, basements, attics, and kitchens.

They are nocturnal creatures and tend to hide in dark, secluded spaces during the day, often within walls, behind baseboards, or in storage boxes.

These pests are attracted to paper and damp clothing, and it’s common to find them lurking in old books, newspapers, and in the laundry room.

Health Risks: Silverfish don’t bite humans or animals and are not known to carry diseases. However, they may trigger allergies in some people.

Extermination: Reduce humidity, vacuum regularly, and use desiccants or bait traps to kill silverfish.

3. Weevils


Identification: Weevils are small beetles with noticeable snouts. They tend to be lightbulb- or pear-shaped and are known to enter buildings by crawling through cracks, openings, and gaps around doors and windows.

Weevils, like many pests, are often found in areas where food is stored. They have a particular fondness for grains and dried goods, making your kitchen, pantry, or anywhere else you store these items a prime target for infestation.

This can include places like supermarkets and warehouses, which have large amounts of food stored.

Health Risks: Like drugstore beetles, weevils do not bite or spread diseases. That said, they can destroy stored foods and render them unfit for human consumption.

Extermination: Inspect all grains, store food in sealed, pest-proof containers, and use traps specific to weevils. For more information on how to get rid of weevils, check out our guide to eliminate pantry bugs.

4. Cockroaches


Identification: Cockroaches vary in size and color but are commonly dark brown with a flattened, oval body, long antenna, and six strong, spine-covered legs. These are fast-moving bugs that are most active at night.

Cockroaches are typically found in areas that are warm, dark, and damp, as these conditions are ideal for their survival. They are often found in kitchens, bathrooms, and basements, where they have access to food and water.

In urban environments, they can also be found in sewers and drain systems. Regular cleaning and proper maintenance of these areas can significantly help in preventing a cockroach infestation.

Health Risks: Cockroaches can carry diseases that cause food poisoning or diarrhea, while their saliva, feces, and cast skins can trigger allergies or asthma.

Extermination: Maintain a clean home, seal entry points, and use baits, traps, or pesticides. For severe cockroach infestations, hire a professional exterminator for assistance, or read our comprehensive guide on how to get rid of cockroaches.

5. Ticks


Identification: Ticks are tiny, spider-like arachnids that are known for attaching themselves to people and pets. They have two primary body parts: a cephalothorax and an abdomen and scissor-like mouthparts designed to pierce the skin of their victims.

Ticks are most commonly found in areas with warm, humid climates, as they require a certain level of moisture to survive.

They thrive in tall grass, brush, and wooded areas where they can easily latch onto passing hosts for a blood meal. This includes forested areas, overgrown fields, and even your backyard if it’s not regularly maintained.

Health Risks: Ticks carry a wide variety of diseases, including Lyme disease, anaplasmosis, ehrlichiosis, Rocky Mountain Spotted Fever, and Tularemia.

Extermination: Keep grass short, use tick repellents, and check for ticks after spending time outdoors. For more information on how to get rid of ticks, check out our complete blog on the topic.

6. Bed Bugs

Identification: Bed bugs are reddish-brown in color with flat, oval bodies. They hide in mattress seams or furniture joints, especially where people sleep. They feed on blood and are known to bite people and pets.

Bed bugs are most commonly found in areas where people sleep or spend significant periods of time. This includes bedrooms, particularly in mattresses, box springs, bed frames, and headboards.

They can also be found in other types of furniture, wallpaper, and even clutter around your home. Bed bugs are excellent hitchhikers and can easily spread from room to room, or even between apartments in a building.

Health Risks: While bed bugs feed on blood, they are not known to spread any diseases to humans. Their bites do, however, cause itching and skin rashes.

Extermination: Use bed bug-proof mattress covers, vacuum regularly, and consider professional extermination. For more information on how to get rid of bed bugs, check out this comprehensive guide.

7. Bat Bugs

Identification: Similar in appearance to bed bugs, bat bugs have short, broad heads and are known to live entirely with humans. Bat bugs, similar to bed bugs, are most commonly found in areas where people sleep.

Health Risks: Bat bugs are not known to be dangerous to humans or animals. While their bites can cause irritation and discomfort, they do not transmit diseases.

Extermination: Remove bat infestations safely and treat the living spaces to remove any remaining bugs.

8. Fleas


Identification: Fleas are tiny insects that are known to jump high, travel quickly, and feed on human and animal blood.

Fleas are most commonly found in areas where pets rest and sleep, as these parasites are often brought into the home by dogs and cats. This can include places like pet bedding, carpets, furniture, and even outdoor areas where your pet spends time.

Fleas lay their eggs in these areas, which can lead to a full-blown infestation if not addressed promptly.

Health Risks: Fleas can transmit diseases like flea-borne typhus, plague, and cat scratch fever. Their bites may also cause irritation, itchiness, and discomfort.

Extermination: Treat pets with veterinary-approved flea control products, clean living spaces thoroughly, eliminate other pest populations, use a HEPA vacuum in your home, and use indoor insecticides and IGRs to provide long-term control.

9. Stink Bugs

Identification: Stink bugs are easy to identify by their shield shape and the unpleasant odor they emit when disturbed. They commonly invade homes in the fall, when they come inside looking for warmth and shelter.

Stink bugs are most commonly found in outdoor environments like gardens and farms, where they feed on plants. Inside, they tend to reside in quiet, undisturbed areas such as attics, wall cavities, and behind baseboards.

However, they are also known to cluster on the sunny exterior walls of buildings in the fall.

Health Risks: Stink bugs are primarily a nuisance pest rather than a health hazard. They do not bite and are not known to spread diseases or cause physical ailments for humans or pets.

Extermination: Seal possible entrances and use pesticides if necessary. For more information, check out our guide on how to get rid of stink bugs.
