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.
In addition to the physical manifestations of bedbug bites, patients can experience significant psychological distress. The stigma that bedbugs are related to poor hygiene (however inaccurate) can lead to poor self-esteem, avoidance of family and friends, and suspension from work.37–39 Management of an infestation can be stressful, costly, and disruptive to everyday life. Worry can lead to insomnia, depression, anxiety, and even delusional parasitosis.37
Most people will find bed bug bites to be small and very itchy. These bites are often mistaken for something else such as eczema. It can be hard to diagnose bed bug bites due to this, especially if someone inflames their skin further by scratching the area. There are some signs that point more strongly to bed bugs over other types of bugs. The number one thing to look out for is a line of bites going straight up your body: bed bugs commonly bite in this pattern as they bite you at the crease where your body meets the bed sheets. It’s very rare to find a single bite like you would with spiders or mosquitoes, and much more common to find clusters and lines. It’s also rare for bugs to bite your face. They most frequently bite your lower body, but anywhere can be bitten.
You can identify a bedbug infestation by checking bedding, mattress seams, furniture, and wall fixtures for the bugs or their traces. Each bedbug is about the size of an apple seed, about 1/4 inch long. You will often see their droppings instead, which are tiny brown or red specks. You may also see small blood stains on sheets or mattresses when a bedbug has been crushed after feeding. Eggs about the same size as the adults might be seen in seams or cracks and you will also see their molted exoskeletons.
All these bed bugs can be dealt with. it is best to use a non chemical treatment to make it safe for your environment . here is one i found, food grade Diatomaceous Earth found at garden centers, follow instructions, and move beds away from the walls, sprinkle in the carpet deeply, on to base boards , ( it works like borax powder for fleas and roaches) .
Bed bugs are obligatory bloodsucking. They have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides.[15] Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.

Symptoms may not appear until some days after the bites have occurred.[5] Reactions often become more brisk after multiple bites due to possible sensitization to the salivary proteins of the bed bug.[3] The skin reaction usually occurs in the area of the bite which is most commonly the arms, shoulders and legs as they are more frequently exposed at night.[5] Numerous bites may lead to an erythematous rash or urticaria.[5]

The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
