What the chemical bed bugs put in you?

Answer 1

When the bedbug climbs on to you for a meal from your blood, which it will usually do when it is dark and you are asleep in your bed, before inserting the tiny tube into you through which it will syphon the blood out of you that it needs, the chemical it injects is both an anaesthetic and a coagulant. This chemical compound is something all bedbugs have inside them which they inject into you instinctively to protect themselves from being harmed by you while feeding. The anaesthetic is similar to what dentists inject into you when you are to have a tooth extracted so once it has taken effect you will not feel anything. So you will not feel the sharp piercing into you when it puts the sucking tube in and will probably go on sleeping peacefully and not feel a need to scratch yourself there during the five minutes or more while the bedbug is sucking the blood out of you. Meanwhile the coagulant effect also makes your blood come out very slowly from the wound the bedbug has made into your skin and through the tube into its mouth sucking structure most usually on your arms or legs near your arteries or veins that carry the blood the bedbug wants. So the bedbug will not be drowned. Only after the bedbug has left you after completion of its meal, with your blood now safely inside it, will the anaesthetic effect then wear off. Only then you may get a maddening itch where it has been and scratch yourself to obtain relief but it is then too late to harm the bedbug. The coagulant effect also continues so blood does not gush out of the wound but just come out slowly and in very small quantities out of the wound before it heals.
