Scabies is a skin infestation of a type of mite known as Sarcoptes scabiei. These are tiny, almost invisible, eight-legged creatures that fall under the same class as spiders and ticks. Scabies mites burrow under the skin to lay eggs and will crawl around on the skin, causing intense itching. Once the eggs hatch, the larvae that emerge will burrow back into the skin, causing even more irritation.
Each of the following pictures of bed bug bites shows typical skin reactions to the insect's saliva. Most people are not hypersensitive to the bites and will show no reaction at all with the exception of two small dots where the bedbug punctured the skin. Other people can develop red papular eruptions (raised inflamed areas) or in severe cases, blisters.
One bed bug will usually take more than one bite. Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. It’s important to remember that the number of bites a person receives is not indicative of the number of bed bugs that feed on that person.
