Bed bug bites and bugs themselves

Bed bugs need blood as their food source, so they have to drink blood to survive.

One bed bug typically bites more than one time. When a bed bug inserts its beak into the skin and discovers the right blood vessel, it will start feeding.

But finding the perfect vessel may take several injections. Also, bed bugs are extremely sensitive to their victim’s movement while feeding.

So, if a sleeping person moves, a feeding bed bug can pull its mouthparts out of the skin and start looking for a tasty place on another body part.

Don’t forget that the number of bites a person gets doesn’t represent the number of bed bugs.
