The first sign of a bed bug problem is obvious: the bed. After bed bugs feed on humans, they'll leave behind blood stains resembling small rust spots. These will usually be found near the corners and edges of the bed. Bed bugs also shed their skin, or molt, several times as they mature, so you may find their oval brown exoskeletons during your search.
You can develop a skin infection if you scratch the bites. Rarely, a more severe allergic reaction to the bites could produce larger welts, blisters, or anaphylaxis. Bedbugs may also trigger asthma attacks and getting too many repeated bites could lead to anemia. Anxiety, insomnia, and sleep disturbances are common due to the stress of discovering bedbugs.
Once you have a suspicion or a confirmed infestation, do not spread things outside of the bedroom. Don't take linens off the bed and go to sleep somewhere else—that will just move the infestation to other rooms. Ultimately pest control operators will tell you to put everything you can through the washer and dryer, since bed bugs cannot withstand high temperatures. I don't think bed bugs would be able to survive solvent-based dry cleaning, but I don't have any first-hand knowledge that that's true. Unfortunately, dry cleaners and Laundromats can be places where people pick up bed bugs. I think it's a low probability, but it only takes one adult female bed bug that has been mated to get an infestation going.

Bedbug bites, like all insect bites, can become infected through excessive scratching, as underneath the fingernails lies a host of bacterial pathogens. If your bites become infected, they will appear red and swollen, feel tender and may drain pus. Typically there will not be a fever unless a substantial area of the skin is involved. If you experience any of these symptoms, you must seek medical attention as it points to a secondary infection. Your physician may prescribe antibiotic therapy or, if the infection is mild, an antiseptic medication that you can buy without a prescription.[12][13][14]

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]
thank you natasha! i’ve reached out to both locations i’ve traveled to and they confirmed their pest control vendors have found nothing. and i had a visual/dog inspection from a reputable pest control company to check my entire house and they’ve found nothing as well. so hopefully this is just a one off and / or mosquito bites that just like biting in a line…can’t help but still be paranoid and sleep bundled up with socks
Blood spots found on one’s sheets, bites and the presence of bed bug feces and cast skins are some of the indications of a bed bug infestation. Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep – the hands, neck, face, shoulders, legs and arms. While not always the case, bed bug bites are often grouped together in a small area and at times may occur in a line or a zigzag pattern. Bites normally look like small, flat or raised areas that may become inflamed, itchy, red or blistered. Bed bug bite reactions don’t always appear immediately after you’re bitten and may take a few days to begin causing symptoms. However, not everyone reacts to bed bug bites in the same manner.
