Bedbug is the common name of insects from the family Cimicidae of the order Hemiptera. They only suck blood from mammals and birds. They approach their hosts at night to suck blood. Other times they hide in places protected from light.
The most well-known species is Cimex lectularius, which is dark reddish brown in color and 5 mm in length. These animals, originally assumed to be bat parasites, are thought to have become human parasites after the cave era.
When the bedbug pierces the skin to feed on blood, it injects an anti-coagulant with its saliva. This enzyme is related to the person's response to the bite and the size of the bite. Another factor that affects the extent of a Bedbug reaction is the number of times a person has been bitten. The bite reactions of people who have been bitten many times are also variable and their response can be more or less intense as the number of bites increases. Bed bugs pierce human skin with thin mouths from which they draw blood. Bed bug bites are not initially painful and can go undetected for hours or days. This bedbug has the ability to absorb human blood for up to 10 minutes with each feeding. Bedbug bites usually appear on exposed skin such as the upper body, neck, arms and shoulders.
Although bedbugs have not been reported to carry any disease by biting, they can cause skin irritations, psychological effects and allergic reactions. Since the bites feel intensely itchy, excessive scratching may cause skin problems or scarring after healing. Bedbugs can survive in any environment, regardless of whether the weather is hot or dry. In very cold weather, they can go into a semi-sleep state and live for 1 year without eating. Pesticides must come into direct contact with their bodies for them to be lethal.
