What Do Bedbugs Look Like

The following Bed Bugs pictures can help identify bugs in your home or apartment as well as any bites or symptoms on your body. Bed bugs at all stages can be seen with the naked eye. When they hatch the insects are small, so a magnifying glass and flashlight can aid in the inspection process.

Bedbugs Slideshow: An Informative Look at Bedbugs

As if you needed something else to worry about, bedbugs, those pests from the old bedtime rhyme are making a comeback. More of a nuisance than a health hazard, they’re showing up to suck blood from people in hotels, college dorms, and hospitals. Take an informative look at bedbugs: what they are, where they lurk, and how to spot them before they get you.

Know the Enemy


Bedbugs are small, flat, wingless insects with six legs that, like mosquitoes, feed on blood from animals or people. They range in color from almost white to brown, but they turn rusty red after feeding. The common bedbug doesn’t grow much longer than 0.2 inches (0.5 centimeters) and can be seen by the naked eye to the astute observer. Bedbugs get their name because they like to hide in bedding and mattresses.

Am I at Risk for Infestation?


Bedbugs are most often found in hotels, hostels, shelters, and apartment complexes where lots of people come and go. Because bedbugs hide in small crevices, they can hitch a ride into your home on luggage, pets, furniture, clothing, boxes, and other objects. Bedbugs are found worldwide, but are most common in developing countries. Once rare in North America, they may be on the rise due, in part, to increases in international travel.

Feeding Habits


These nocturnal creatures can hide in beds, floors, furniture, wood, and paper trash during the day. We humans usually become their dinner during the night, with peak biting activity just before dawn.They can obtain their meal in as little as three minutes, after which they are engorged and drop off the host, then crawl into a hiding place to digest their meal. Bedbugs can live for 10 months, and can go weeks without feeding.

Signs and Symptoms of Bedbug Bites


Amazingly, these sneaky little bloodsuckers dine on you without waking you. You don’t feel their stealthy bite because they inject a numbing agent into your body, along with an anticoagulant to keep your blood flowing as they suck. The first sign of bedbugs may be itchy, red bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites.

Treating Bites


Bedbug bites do not usually require treatment. If a secondary infection occurs (usually from scratching), apply a local antiseptic lotion or antibiotic cream or ointment. Creams with corticosteroids and oral antihistamines are used for the primary, unbearable symptom of itch. In these more severe cases, you may need to see your doctor.

Do Bedbugs Transmit Diseases?


Bedbugs are more of a nuisance than a health hazard. In a recent study, researchers reviewed 53 recent studies on bedbugs and their health and medical effects. The results showed that although bedbugs have been blamed for the spread of up to 40 different human diseases, there is little evidence to suggest they are carriers of human disease.

Bedbug or Imposter?


Don’t assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It’s best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.

Bite Back Against Bedbugs


Professional exterminators should get involved right off the bat—tell your landlord, super, hospital administrator, hotel owner, or you call a professional right up front. The exterminator will locate the bed bugs (which may be found in more than one location) and exterminate as needed. YOU will have to do a lot of laundry.

Overview: What bed Bugs look like to the Naked eye

The following Bed Bugs pictures can help identify bugs in your home or apartment as well as any bites or symptoms on your body. Bed bugs at all stages can be seen with the naked eye. When they hatch the insects are small, so a magnifying glass and flashlight can aid in the inspection process.

Bed bugs have a flat, oval-round body shape and have 6 legs.

Bed Bug on Person’s Thumb

When looking for bed bugs in the home, first realize that they follow a lifecycle. The insects start as an egg, move through infancy (called being an Instar or nymph), followed by adulthood (see life cycle chart below and National Geographic video).

Pictures of Baby Bed Bugs

In terms of skin reactions, it varies by person. Some people are not allergic to bed bug bites and will show no skin reaction. Others are highly allergic and will experience red skin bumps, irritation, and rash. Severe cases result in rashes. See pictures below for examples.

Bed bugs live for approximately 10 months and move through a life cycle from egg to adult. Infestations usually start with a female bed bug who would bite the host for blood upon arrival in the bed, and then for another “meal 2 weeks later.

At that point, she would lay eggs in the home at a rate of 3 per day. It takes 2 weeks for an egg to hatch. The just born nymph looks for food right away and becomes an adult bed bug in 4 months. The speed of reproduction and total life span is affected by room temperature and what is described assumes a room at 68F (20C).

The adult bed bug lives for approximately 10-months, but can live without feeding up to a year if you decide to move to another room. A typical infestation has between 4 and 500 bed bugs.

Bed Bugs Lifecycle

Types of Bed Bugs Pictures

Bed Bug Lifecycle. Note how each bed bugs image changes as they move from stage to stage.

Bed bugs move through 5 developmental stages before they become an adult. They must eat a blood meal before they move from stage to stage. The insects shed their exoskeleton between each stage. It takes 37 days for a bed bug to move from egg to adult in ideal temperatures which is greater than 72 degrees Fahrenheit.. An adult will live for about 1 year and for only 70 days if living without food. They can live longer in colder temperatures without a meal.

Bed bugs images at each lifestage. To lay eggs and grow, bedbugs need a blood meal. They hatch in 10 days and become adults in 2 to 4 months. (Texas A&M)

How do you get rid of bed bugs?

There are two ways to get rid of bed bugs, do it yourself, or our recommended method, which is to call an exterminator.

Why an exterminator? Bed bugs are the hardest insect to eliminate, even for a pro. They require up to 3 treatments to eliminate an infestation. A good place to start is with a call to a national network such as Home Advisor that can certify the skills of a local exterminator (or call 866-214-8380).

If you are going to “do it yourself”, the best way to remove an infestation is to buy a kit which contains a collection of products and zippered covers needed to

  1. kill the bugs that you can see
  2. kill the bugs you can’t
  3. protect against eggs you miss.

Good reasonably prices choices and kits are offered by Bed Bug Supply. More than one type of spray is needed to kill bedbugs, which is why a kit is essential.

If your mattress is over eight years old and showing signs of wear you may consider replacing it. See our guide for detailed instructions on pest control for eliminating bed bugs.

Bed bugs usually climb up bed legs or a headboard. They are attracted to the carbon dioxide exhaled by humans when breathing. Hiding spaces such as mattress seams are convenient ways to stay close to a human source for their next blood meal.
