Bed Bugs Live Without Food from TWENTY to 400 times, depending upon temperature level and also moisture. Older phases from nymphs can survive longer without supplying than younger ones, and grownups have actually endured without food for more than 400 times busy at reduced temps.
Bedbugs have long been known. Believe it or not, bedbugs have been biting since the cave dwellers 30,000 years ago, bedbugs suck the blood of humans in Egypt, Greece, and Romania since several thousand years ago. The first person who knows how to control bedbugs is a British scientist named John Southall who lived in the 18th century in London. He wrote his first book, 44-page book about bedbugs entitled “A Treatise of Bugs” in 1730. The population of vermin known before World War II, but with improved hygiene, especially with the widespread use of DDT in 1940 and 1950, all insects disappeared. At the beginning of 1950 to ending the problem of bedbugs in 1990 has begun to diminish. After disappearing for nearly half a century, now bedbugs reappear and become pests are quite disturbing, especially for hotels and apartments.
Adult bedbugs have flat body shape and slightly oval. With a body length of 5 mm and a width of 3 mm. His body is covered with short hair smooth, brownish, but sometimes reddish when new blood sucking, or purple when the rest of the old blood still in the stomach. Nymph lice have a pale color and smaller than an adult. When hungry, as the paper is clear and thin, but his body could be thickened to 5-fold after full and stronger if abundant food. The ability to fly these insects have disappeared, the remaining of the functions of the original wing, now nothing more than a pair of short valve segment in the middle of the chest.
Cimex lectularius one species of lice, parasites, especially in humans, but can bite and suck the blood of other animals such as cats, dogs, rabbits, birds, bats, rats, hamsters, chickens and ferrets. Bedbugs have incomplete metamorphosis. Bedbugs are females capable of producing eggs 5 to 500 grains per day. Eggs are approximately 1 mm, creamy white, slightly curved and shaped somewhat long, with the head or the operculum at one end.
Eggs stored 10 to 50 grains in the cracks of the board, flooring, wallpaper, and on rough surfaces. When the egg is still fresh (recently issued by the host), eggs coated with a layer of sticky like glue, the sturdy case and causes the egg to attach to other places where they are stored. Eggs require a minimum temperature of 13 ° C to hatch. The eggs hatch within 1 to 2 weeks to the nymphs are white with a length of about 1 mm are stored in small crevices. A total of 100 eggs was incubated until it becomes an adult, need 500 food such as blood, which means that there were 500 bites in humans are not fortunate who do not know that their beds full of bedbugs.
Nymph lice consists of five inter with 5x molt before they become adults. Nymph period takes about six weeks. Nymphs have a similar shape to the adult, but smaller. Each complete the nymph stage, it takes at least one blood meal fully before proceeding to the next stage of growth.
When sucking blood, bedbugs using jointed half or bottom half of the head. If not used, the back half tied under her head, and when used for eating, beak protrude forward. Part consists of two pairs of needle style as supported by the lower lip called labium. Both pairs of stylet, when folded and pressed together, will form two pairs of tubes. Large tube to suck blood and lymph small tubes to pass through the saliva into the capillary channel to the puncture wound. Bedbugs carefully chose their skins through the assessment carried out by the movement of the beak, and then pricking the skin with the help of a sharp stylet tip, in the capillaries. The sap is then pumped through the saliva of the mouth that comes from the sap of the salivary glands located in the chest. The mixture of blood and saliva sap is sucked into the channel stylet and delivered to the food channel. Sap saliva prevents blood curdling host, also prevents clogged fine stylet, as well as the intestinal tract.
Bedbugs takes 3 to 5 minutes to eat, after swallowing, and then they break away from its host. They crawl into a hiding place and stay a few days to digest food. When hunger comes again, they emerged from his hiding place and hunt for prey again. After completion of sucking blood, he glared remarkable because the blood is sucked up to six times the body weight. If the food is not available, the nymphs can survive for several weeks in warm or several months in cold temperatures. Adult bedbugs can survive for 2 months to 1 year without eating and 4 years in normal circumstances with food for sure.
Bedbugs are nocturnal, but when humans sleep. His body was flattened and can hide in tiny crevices, especially in bed, frame / box. Bedbugs do not have nests like ants or bees, but tend to congregate in hidden places. Characteristics of the site of infection is characterized by dark spots and stained; it is a dirt of bedbugs. Activity meal starts from evening until dawn. During the day, bedbugs tend to stay away from the light; they prefer to hide in places such as mattress seams, interior, and the edge of the bed, an area close to furniture, carpets, boards, walls, and a small hole in the timber.
Eggs, egg shells and husks can be found at the hideout. If you are very hungry, maybe bedbugs come out of hiding to look for food.
In early infestations, bedbugs are found only in the seams, pile or bending the mat, but ultimately they are scattered across the bed. In severe infestations they can be found behind the divan / boards, windows, doors, paintings, frames, furniture, wallpaper, cracks in the walls. Bedbugs do not usually bite people on the head like a bug. Symptoms in different people after being bitten. Itching and red swelling will occur after 1 to 14 days later. Therefore, if the itching and red swelling had appeared, meaning the infection of bedbugs in this area has been going on for long. Others have little or no reaction, and in some people who are immune to such reactions. Bedbugs suck the skin when people fall asleep (face, neck, shoulders, back, arms, legs, etc.). Swelling and itching is often misunderstood and associated with other things, like a mosquito bite. In addition to homes, bed bug infestations can also be found in hotels, apartments, means of transport (ship, plane, train, bus), and restaurants.
