Why Bed Bug Bite Takes That Long To Show Up?
As mentioned earlier, a bed bug is a small insect. Although it is visible to the naked eye, yet it can easily be written off or ignored when cleaning the house. One needs to take proper care in eliminating these insects.
A bed bug can bite a person without the person even noticing it. The insect feeds on human blood at night times when people are in deep sleep. People do not even feel the insect crawling upon them once they are asleep. The bug makes a small bite that, at first can only be viewed with a magnifying glass.
Moreover, the saliva of the bug contains an anesthetic. This chemical prevents the person from getting disturbed or getting awake and helps the bug feed to its heart’s content. This is one of the reasons behind the slow realization of a bed bug’s bite.
Another reason behind this long time is the small mouth of the bug. As the small mouthparts of the bed bug bite one’s skin, since the area affected is small, the bite does not show up early.
However, as the effect of anesthetic slows and the wound spreads to the surrounding skin area, it gets swelled up. This swelling and skin redness becomes more pronounced when the mast cells release an enzyme called histamine. Such a prolonged series of actions take place within 48 hours of the bug bite.
A bed bug bite takes 24 to 48 hours to show up. When a bug bites a person, it leads to a small bite which is so small that it is invisible to the human eye. In addition to that, the insect also releases an anesthetic to the host’s body because of which the person does not feel it.
However, as the effect of the anesthetic wears off after a couple of hours, the bite mark starts to grow. It becomes red, swollen, and itchy after two days.
