Bed bugs are small oval insects that feed exclusively on blood. They are usually found near or inside beds and bedding or other sleep areas, including the mattress, box springs, and bed frames. Other than this, they can be found in cracks in furniture or in any type of textile. Bed bugs are mostly active at night and attack the exposed skin of an individual while sleeping. These can easily be transported from one area to another with suitcase, shoes, clothes etc, without being noticed.
Bed Bugs are blood-sucking in nature. They survive on blood for their survival. In addition to blood, they also require water for their which they obtain from the water vapors in the surrounding air. These parasites are attracted to their hosts primarily by carbon dioxide, warmth and by specific chemicals. They attack humans while they are sleeping and prefer mostly feeding on exposed skin areas. Exposed areas of a human such as the face, arms, hands and the area around the neck are most vulnerable to bed bug bites. Bed bugs are known to be dwellers of extreme starvation conditions. The adult bed bug can live for about a year without being fed.
Bed bugs do not always bite humans. However, exposed skin area is an invitation to these insects for sucking up blood. They feed by piercing the skin and withdrawing blood through an elongated beak, without making the host realize it. Bed bugs can extract blood from humans for about 10 minutes and can go unnoticed.
The extent of allergy caused due to bed bug bites varies from human to human. Most bedbug bites are painless at first, but later turn into itchy welts. The bites usually cause swelling without causing any spots. However, when a large number of bugs feed at the same time on a smaller area, red spots may appear.
So where do they live? Bed Bugs are not limited to a particular area but can be found anywhere. They have been spotted at apartments, hotels, schools, colleges, offices, stores, clothing stores, homes and even in public transportation by pest control companies.
Bed bugs can conceal themselves in minute cracks that are often close to their host’s environment. That’s the reason they are mostly found in an around bed areas such as on mattresses, closets, picture frames and wallpapers. They have also been known to survive in temporary habitats like suitcases, backpacks, and seats in cars, buses, trains and metros.
