The itch and the redness are not just the only thing to watch for and for you to be able to say that you really have been attacked by this arthropod, you have to have a clear grasp of what bed bug bites are.
People often fail to acknowledge the presence of the parasite unless the symptoms become too obvious and pronounced.
But before identifying bed bug bites, getting some information on what causes them might be appropriate.
The culprit for this parasitic itch is brought about by bed bugs.
This organism does not have any means of flying, as they are wingless.
However, they move around by crawling fast.
They are one of the commonest pests around.
They feed exclusively on the blood of warm-blooded animals and so they are great parasites of humans, birds and bats.
The bugs are very small and this feature makes them well suited to the crevices and deep portions of the bedding where they are commonly found.
Their minute size and with their deep brown or burnt orange coloration adds up to the perfect camouflage of this species.
Homes, which were formerly devoid of this species, gain their entry through luggage, furniture, clothing, and boxes that have been carried from somewhere.
Even a few individuals can actually establish a large population that can readily attack innocent hosts once they are hungry.
So how can you really tell that this form of parasite has attacked you? Unfortunately, the signs are not at all exclusively associated with the bug.
Other parasitic infestations or even mosquito bites do appear very similar to the attack of this parasite.
In order to have a strong confirmation that you really are harboring these parasites in your bed you have to take a careful look on the following:

• Bite patterns - initial signs would reveal small reddish bumps on your skin very close to that of a mosquito bite.
  What is noticeable and exclusively done by this parasite is the pattern of three or four reddish bumps that appear adjacent to one another.
  Often the bites are arranged as if they have been done one at a time, once for every meal.
  
• When the symptoms were observed - The effects of the bite varies greatly among individuals.
  Where others may manifest extreme symptoms such as welting, itchiness and swelling to others who do not manifest even the slightest symptom, it is important to consider the lag between the times the patient was first bitten up to the time that the symptoms are expected to surface.
  Among individuals who had few bites, the difference may last up to one week.
  The lag becomes shorter or narrower once the victim is exposed frequently to the parasite, as bed bug bites are more common.
