Six Common Types of Bugs Found in Houses

Home / Blog / Six Common Types of Bugs Found in Houses

While being a homeowner, you will most likely have uninvited guests that crawl in your home from outside. Here’s a list of the most common types of insects that may cause damage while living in your home.


Ants are one of the most common insects found in and around homes in the U.S. While living outside, they can nest in lawns, walls, stumps and even under foundations. They sometimes find their way indoors through even the tiniest cracks while searching for water and foods in the kitchen or pantry.

Aside from the nuisance ants cause, they rarely cause harm to the home. However, Carpenter ants can nest in your home’s wooden structure where they can cause extensive, structural damage through tunneling.

2. Cockroaches

German cockroaches are about one-half of an inch in length. They have six legs, two antennae, and wings that they sometimes can use to glide. German cockroaches are the most common type of cockroach to be found inside your home.

Cockroaches can contaminate food, damage paper, and fabric, trigger allergic reactions in some people and carry bacteria wherever they go. Those bacteria can potentially cause food poisoning, dysentery, diarrhea and other intestinal issues.

3. Termites

Termites are usually one-eighth of an inch to 1-inch long. They vary in color from shades of white (worker termites) to brown to black (alates or winged reproductive stage termites). Alates are sometimes confused with flying ants because both have wings and antennae.

The scariest thing about termites isn’t what they look like — it’s the damage they can cause to homes. Often called the “silent destroyer,” termites may be eating their way through the wood in your house without you even knowing it. In fact, termites cause up to $5 billion a year in damages in the U.S. alone.

4. Bed Bugs


Bed bugs are small, flat, oval-shaped, reddish-brown insects — they basically look like tiny apple seeds with legs. They can be found in the cracks and crevices of your home,  your mattress seams, your sheets, your furniture, your electrical outlet plates, behind your baseboards and even in picture frames. Most of the time, bed bugs feed on blood, usually while people are sleeping, which gives them a particularly “creepy” reputation.

5. Fleas

Fleas are tiny, reddish-brown, wingless insects with shiny bodies covered in microscopic hair. Although they can’t fly, they can jump long distances, which their legs are designed for. They are ectoparasites (live on the outside of their hosts) that feed on the blood of animals like dogs, cats, rabbits, squirrels, rats, mice and people.

Not only are fleas a nuisance within the home, they can carry parasites such as tapeworms.

6. Silverfish

Silverfish are pearl-gray, shiny and look like a fish in water when they move, which gives them their name. They have slender, segmented bodies, and they like to live in dark, damp areas, such as basements and bathrooms.

Silverfish sometimes live in stored boxes in garages and sheds. Other times you may find them feeding on the glue in books as well as on linen, silk, and dead insects. They are best known for damaging papers, clothing, and wallpaper (because they feed on the glue that holds it to the wall).
