Insect bites, including those from the bedbug, have been proposed as a factor contributing to the formation of a cutaneous reaction termed papular urticaria. Patients with papular urticaria have been shown to demonstrate immunoglobulin (Ig) G antibodies to bedbug (C lectularius) antigens.  Thus, IgG against C lectularius, Cimex pipiens, and Pulex irritans in patients with papular urticaria may contribute the pathogenesis of this condition.
Bedbugs are small oval-shaped non-flying insects that belong to the insect family Cimicidae, which includes three species that bite people. Adult bedbugs reach 5 mm-7 mm in length, while nymphs (juveniles) are as small as 1.5 mm. Bedbugs have flat bodies and may sometimes be mistaken for ticks or small cockroaches. Bedbugs feed by sucking blood from humans or animals. Cimex lectularius is the scientific name for bedbugs.
When you return home, quarantine your bags. Decontaminate your luggage and clothing by putting your entire suitcase into a large chest freezer (if you have one) for four days, suggests Gondhalekar, before bringing them back into your home. Extreme hot or cold temperatures kills bed bugs. You can also put your clothes in the dryer on a hot setting for 30 minutes, and try steam cleaning your luggage and clothing.
Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
Bed bugs are small, flat insects that feed on our blood, typically at night, while we are sleeping. Adult bed bugs are about 1/4 of an inch long, have flat, rusty-red-colored oval bodies, and look like an apple seed. They feed for about 3-10 minutes and their bodies swell and become bright red. During the bed bug life cycle, a female can lay 200-400 eggs depending on food supply and temperature. Bed bugs don't fly, but can quickly walk across floors, walls, and other surfaces.
Bedbugs normally feed at night, usually approximately 1 hour before dawn. However, if the conditions are favorable, they also feed during the day. Feeding takes 3-12 minutes. In proper conditions, adult bedbugs can survive without a meal for 1 year or longer. Each female lays approximately 300 eggs in her lifetime. The eggs hatch in 10 days. The nymph stage lasts 6 weeks, undergoing 5 molts.
However, low-level infestations are also much more challenging to find and correctly identify. Other insects, such as carpet beetles, can be easily mistaken for bed bugs. If you misidentify a bed bug infestation, it gives the bugs more time to spread to other areas of the house or hitchhike a ride to someone else's house to start a new infestation.

These nocturnal creatures can hide in beds, floors, furniture, wood, and paper trash during the day. We humans usually become their dinner during the night, with peak biting activity just before dawn.They can obtain their meal in as little as three minutes, after which they are engorged and drop off the host, then crawl into a hiding place to digest their meal. Bedbugs can live for 10 months, and can go weeks without feeding.
Bed bugs were mentioned in ancient Greece as early as 400 BC, and were later mentioned by Aristotle. Pliny's Natural History, first published circa AD 77 in Rome, claimed bed bugs had medicinal value in treating ailments such as snake bites and ear infections. (Belief in the medicinal use of bed bugs persisted until at least the 18th century, when Guettard recommended their use in the treatment of hysteria.)
