Habitat & Signs

  • Bed bugs live in and around where humans live and are not always found in beds
  • Large infestations of bed bugs can lead to a sweet scent in the room

  • Bed bugs can survive to 113 degrees Fahrenheit or as low as 45 degrees Fahrenheit if acclimated
  • Clutter impedes bed bug inspection and control
  • Some dogs are trained specifically to detect bed bugs and the dogs work well; however, it is imperative to have a properly trained dog and handler. Training should be done by a professional trainer and any certifications for the team should be by a national credentialing organization.
