Bedbugs are flat, wingless insects about 0.6 cm (0.25 in.) long. They range in colour 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 picture of a bedbug.
Bedbugs are not known 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.
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.
