Bedbugs - Topic Overview
What are bedbugs?
Bedbugs are flat, wingless insects about
0.25 in. (0.6 cm) long. They range in color
from almost white to brown. They turn rusty red after feeding. Like
mosquitoes, bedbugs feed on blood from animals or people.
Bedbugs have that name because they like to hide in bedding and mattresses.
Bedbugs usually hide during the day and are active at night when they feed. They
can go for weeks without feeding. See a

Bedbugs do not seem to spread disease to people. But itching from the bites can
be so bad that some people will scratch enough to cause breaks in the skin that
get infected easily. The bites can also cause an
allergic reaction in some people.
Where can you find bedbugs?
Bedbugs are found worldwide. They are most often found in hotels, motels, hostels, shelters, and
apartment complexes where large numbers of people come and go.
Because bedbugs hide in small crevices, they can come into your house on
luggage, furniture, clothing, pillows, boxes, and other objects. The bugs can
hide in beds, floors, furniture, wood, and paper trash during the day.
How do you know if you have bedbugs?
The first sign of bedbugs may be red, itchy bites on the skin, usually on
the arms or shoulders. Bedbugs tend to leave straight rows of bites, unlike
some other insects that leave bites here and there.
Look also for
these other signs:
- The bugs themselves, especially along the seams
- Tiny bloodstains on sheets and
- Dark spots of insect waste where bedbugs might crawl
into hiding places on furniture, walls, and floors.
- A sweet odor
from bedbugs' scent glands where bedbugs are found in large numbers.
How can you treat bedbug bites?
Home treatment can help stop the itching and prevent an infection. You can:
- Wash the bites with soap to lower the chance of infection.
- Use calamine lotion or an anti-itch cream to stop the itching. You can also hold an oatmeal-soaked washcloth on the itchy area for 15 minutes.
You can buy an oatmeal powder, such as Aveeno Colloidal Oatmeal, in drugstores.
Or you can make your own oatmeal solution. Wrap 1 cup (0.2 L) of oatmeal in a cotton cloth, and boil it for a few minutes until it is soft.
- Use an ice pack to stop the swelling.
- See your doctor if you think the bites may be infected.
