People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.

I woke up this morning trying to figure out what’s this pain on my back and sadly I found out it was munched by a bed bug! It’s so gross and I don’t want my girlfriend to see it!  Can an antibiotic cure me from these bites? I only have antibiotics here and the nearest mini convenience store is 5 kilometers away so yeah help me please! Thanks Natasha!

I was at a friend’s house in the afternoon for 3.5 hrs and woke up at 3 am with severe itching, and pain, on my back. My entire back was covered in bites/rashes, clear lines and clusters. I had no idea what it was and went to the doc. Someone suggested shingles. Doc said definitely bug bites. I talked to my friend and they admitted to having seen bed bugs on the couch “recently.” Freaking out I flipped over my entire bedroom, found nothing. Washed the clothes I wore in hot water and high heat drier. I am hoping that the feeding occured during those few hours and no buggs travelled with me. All I had was me, no stuff. Can they “migrate” on people?

Bed bugs occur around the world.[36] Before the 1950s about 30% of houses in the United States had bedbugs.[2] Rates of infestations in developed countries, while decreasing from the 1930s to the 1980s, have increased dramatically since the 1980s.[3][4][36] Before the 1980s they were common in the developing world but rare in the developed world.[4] The increase in the developed world may have been caused by increased international travel, resistance to insecticides, and the use of new pest-control methods that do not affect bed bugs.[37]
Cutaneous reactions to bedbug bites can vary widely and are easily confused with other conditions (Table 1).15–19 A typical lesion is a 2- to 20-mm, pruritic, erythematous maculopapule with a central hemorrhagic crust or vesicle.5,8 Macules, papules, wheals (Figure 3), vesicles, bullae, and nodules have all been reported,20 as have asymptomatic lesions with a barely visible punctum as the only evidence of a bite.8 Bites vary in number and are preferentially distributed in unclothed areas (e.g., face, neck, extremities). Unlike many other arthropod and insect bites, bedbug bites are rarely located in the popliteal fossae or axillae.21 Lesions can be noticeable immediately when waking up or several days later, with the reaction often progressing from delayed to immediate with subsequent exposures22–26  (Table 2). The classic bedbug rash is referred to as “breakfast, lunch, and dinner” because it commonly presents as several bites in a row or cluster 20 (Figure 4).
Thank you so much for all the information. I just found a bed bug in my room at 5:00 AM in the morning. I have been getting these red itchy rashes for more than 2weeks . It’s extremely annoying and in spite of looking every where , I couldn’t find anything. These Biggs are so difficult to find. Now after reading this I feel they are even more difficult to eradicate.

Bed bugs tend to congregate, but it’s also common to find a single bug or some eggs here and there. A thorough inspection and treatment may take up to several hours. Some companies use specially trained dogs to assist in finding small dispersed infestations, especially in such places as hotels, schools, libraries and office buildings. When properly trained, bed bug detection dogs can be quite effective. Relatively few companies are routinely using them, however, due to the expense of training and maintaining such animals. Reliability of some of the dogs is also being questioned as more enter the market.    
Bed bugs are a traveler's nightmare. They can be picked up in hotel rooms, leaving red itchy bumps and possibly rashes to ruin your vacation. Or even worse: If you accidentally bring them back with you, they could infect your whole house. To prevent a plague of bed bugs, here are some tips of what to check while you're on the road and how to determine the symptoms of bed bug bites.

Bedbugs often invade new areas after being carried there by clothing, luggage, furniture or bedding. The creatures don't discriminate between dirty and clean homes, which means even luxury hotels can be susceptible to bedbugs. The most at-risk places tend to be crowded lodgings with high occupant turnover, such as dormitories, apartment complexes, hotels and homeless shelters.

Insecticides might also have their work cut out for them: Entomologists have known that the common bedbug has built up resistance to some typical insecticides such as those containing certain pyrethroid chemicals like deltamethrin, according to Entomology Today. Deltamethrin apparently paralyzes an insect's nervous system, according to Cornell University.
While cleaning up infested areas will be helpful in controlling bedbugs, getting rid of them usually requires chemical treatments. Because treating your bed and bedroom with insecticides can be harmful, it is important to use products that can be used safely in bedrooms. Do not treat mattresses and bedding unless the label specifically says you can use them on bedding.
