Where Do Bed Bugs Come From?

  • Lizard Info
  • May 30, 2025

When you return from a weekend away, the last thing you want to do is worry about pests. You want to unpack your bags, settle in for a cozy night’s rest at your home in San Jose, CA, and relax. 

But if you discover itchy red bites all over your body, chances are, that relaxing isn’t going to happen.

Pests like bed bugs can make a sudden and abrupt appearance, disturbing your peace of mind and sending you into a panic. You might be wondering, where do bed bugs come from, and is there any way to prevent them?

At Banner Pest Services, we’re here to answer that very question. Keep reading to learn everything you need to know about bed bugs, where they come from, and most importantly, how to get rid of them for good in  the San Francisco Bay and East Bay Area.

What Are Bed Bugs and Where Do They Come From?

Bed bugs are tiny, flat, wingless insects that feed on the blood of humans and animals while they sleep. These pests are reddish-brown, about the size of an apple seed, and are notorious for their ability to hide in the tiniest crevices.

But where do bed bugs come from? In short, these pests are expert hitchhikers. 

Bed bugs don’t discriminate. They’re found in five-star hotels, suburban homes, and urban apartments alike. Cleanliness does not determine whether or not you’ll encounter a problem. Instead, they spread through:

  • Travel: Luggage, clothing, and hotel rooms are common ways bed bugs travel into your home. They often crawl into the folds and seams of suitcases. 
  • Public Transportation: Think buses, airplanes, and trains, where luggage and personal belongings are stored closely together.
  • Secondhand Items: A “great deal” on used furniture can sometimes bring along hidden surprises. Furniture, mattresses, and even electronics bought from thrift stores or online marketplaces.
  • Shared Spaces: Bed bugs thrive in apartment buildings, dorms, and public transportation due to their close-quarters environment.

It’s no surprise that increased global travel and densely populated areas, like San Jose, have contributed to the rise in bed bug infestations.

Signs of a Bed Bug Infestation

Wondering if you might have bed bugs? Look out for these telltale signs:

  • Small reddish-brown bugs hiding in seams or cracks.
  • Rusty blood stains on sheets or mattresses.
  • Itchy, red bites arranged in clusters or lines.
  • A musty, sweet odor near sleeping areas.

If you notice any of these signs, it’s time to act fast. Infestations can quickly grow out of control.

While bed bugs are not known to spread diseases, their bites can cause itchy welts that lead to scratching and an increased risk for skin infections. You may find yourself suffering from sleep deprivation from the chronic discomfort, or even anxiety and stress that are worsened as the problem intensifies. 

These pests are also incredibly resilient. They can live for several months without feeding, making it difficult to eliminate them without professional help.
