What Are Early and Late Signs of a Bed Bug Infestation?

Learning the early and late stage signs to a bed bug infestation can influence how you deal with these pests, and your personal belongings. Catching an infestation early can make the process a lot easier on your and your loved ones, and lessen the chance that you’ll spread bugs to other locations.

Early signs

Early signs of bed bugs in your home can be hard to spot, so we recommend periodically checking your mattress and other furniture for signs, especially if you live in an apartment building or other shared accommodation, or if you’re a frequent traveler. You’re more likely to have bed bugs hitch a ride in your belongings if you are often in areas with lots of human traffic.

Signs of an early infestation are:

  • Sudden appearance of red bumps, rashes, or marks along skin (most commonly arms, shoulders, and legs)
  • Small brown blood stains found on mattresses or furniture
  • Bloodstains from bites on mattresses and furniture
  • Bed bug eggs or nymphs
  • Molted exoskeletons in the folds and creases of your furniture
  • Visual identification of a bed bug

Late signs

Unfortunately a lot of people don’t notice bed bugs until there is a full-blown infestation in their home, but that doesn’t mean it’s too late for treatment. Aside from the signs above, you can also expect:

  • Multiple bed bugs in baseboards, folds and creases of furniture, wallpaper, carpeting, books, and clothing
  • Neighbors in adjacent units with infestations as well (in the case of apartments, condos, etc.)


If you have found the sign of a bed bug infestation, such as eggs, nymphs, adult bed bugs, or exoskeletons, be sure to notify the appropriate person. If you’re in an apartment, this will be your landlord. If in a hotel, the manager. They will likely be able to help you (and most times, will be required to by law)!

Report the bed bugs online to help fellow travelers know the bed bug history of a location. This can help protect people in the future from spreading pests and causing outbreaks.

Become familiar with the symptoms of bed bug bites, find home treatment options, and hire an exterminator immediately. The sooner you act, the more likely you are to have a positive outcome!
