How do you know if bedbugs are under your skin?

Because unlike certain other inspects bedbugsdo not go under people's skin. Each bedbug climbs on top of your skin during the night, normally while you are fast asleep and stays on your skin only for a maximum of about 5 to 10 minutes while having their meal, which is some of your blood. After they have completed that meal they then leave you and crawl back to their hiding place, which will usually be in a crack or crevice very near to where you sleep such as in your mattress.

When first on your skin they inject an anaesthetic into you before piercing your skin with a tiny very sharp point and it then inserts a tiny tube through which it slowly sips the blood out of you into its mouth. You will not normally feel anything during its meal, even if you are awake because the anaesthetic makes it numb and because they only come out in the darkness you are unlikely to see them, except in the daytime if you happen to disturb one or more in their hiding place, such as when making your bed or turning your mattress over.

The way you usually discover that bedbugs have been on you is by the little red marks you will see on your skin in daylight where bedbugs have had meals of you during one or more night times. After the anaesthetic has worn off the area of your skin where they pierced you may also itch maddeningly, but this only happens to certain people.
