In infestations with persistent, repeated exposures, bed bug bites may appear in crops. Also, since bed bug bites usually take three to six weeks to heal, as long as the infestation is still present, new bites may accumulate even as the older ones start to resolve. Thus, people may have various bite reactions in various stages of evolution at the same time.
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).
This…this…ugh!!! I went to the doctor and the moron said my son and I had scabies. I wish, they are easier to get rid of than bed bugs! He gave us a CREAM to cover our bodies from head to toe. Said to bag everything that can’t be washed. Make sure sealed air tight for 3 days. Ok I believed him after all he is a doctor. Did everything just as he said I had to pay 70 $ cash for my medicine. I had purchased tea tree oil for the bites before the prescription. I lost 3 weeks of work because of how severely I scratch in my sleep.
It’s also possible that you won’t see a reaction the first time a bedbug bites since it sometimes can take the body a while to react. (6) Some people will have an immediate reaction, while for others it could take two weeks to emerge. Your body will likely become more sensitive to bedbug bites over time, and if you get bitten repeatedly, it could be only a matter of seconds before your body shows a response.

Bites on dogs and cats will look much like bites on people, and the pet owner may actually suspect a mosquito or flea bit the pet. As with people, bed bugs do not stay on pets, but return to a protected harborage site after feeding. In addition to bites, the presence of the bug’s feces, cast skins and the animal’s irritation at night are also indicators of bed bugs biting pets. Therefore, one of the best things to do is inspect the pet’s bedding and frequently groom the animal while being vigilant for the telltale signs of bed bug presence.
