Common Signs Of Bed Bug Infestations

Bed bugs are tiny insects that can easily go unnoticed, but there are telltale signs that can indicate their presence in your home. Some common signs of bed bug infestations include:

  1. Bloodstains on the sheets or pillowcases: Prolonged feeding by bed bugs can result in bloodstains on your bedding.
