People often wonder why a biting bed bug doesn’t wake up its human host when it feeds. The answer is that components in bed bug saliva act as an anesthetic and promote increased blood flow at the bite site, making the feeding process quick and nearly painless.
After feeding, bed bugs move to secluded places and hide for 5-10 days. During this time, they do not feed but instead digest their meal, mate and lay eggs.
