Where Do Bed Bugs Come From? A Complete Guide

While it can seem like bed bugs spawn from the pits of darkness, there’s a more down-to-earth reason they find their way into homes (and it has nothing to do with cleanliness). So, where do bed bugs come from? These pests spread by hitching rides on items that have come into contact with other infested areas. Let’s do a deep dive into where bed bugs come from and what to do if there’s an infestation.

5 Common Ways Bed Bugs Get into Homes

To understand where bed bugs come from, you must learn where you could have picked them up. These are the most common locations where people unknowingly pick up bed bugs and bring them home.

1. Travel

Your travel luggage is one of the top places bed bugs love to hide. Hotels, buses, airports, and even rideshares can be infested. Bed bugs cling to fabric, zippers, and seams, hitching a ride into your home undetected.

2. Secondhand Furniture or Clothing

Used mattresses, furniture, and clothes can harbor hidden bed bugs or their eggs. Even clean-looking pieces from thrift stores, garage sales, or curbside finds should be carefully inspected, washed, and treated before bringing them indoors.

3. Neighboring Infestations

If you live in an apartment, condo, or duplex, bed bugs can travel between units through vents, walls, electrical outlets, and plumbing. One infested neighbor can quickly turn into a building-wide problem.

4. Visitors

Guests who have an active bed bug problem at home may unknowingly bring them over in their bags, coats, or shoes. If any of these come in contact with your soft furniture, bed bugs can hop off and hide until they become active at night.

5. Public Spaces

Bed bugs can also come from public spaces, such as your workplace, a movie theater, a hospital, or public transit. They cling to clothing, bags, or upholstered seats and can hitch a ride home without being noticed.

What Attracts Bed Bugs?

Bed bugs are primarily attracted to body heat and carbon dioxide, both of which people naturally emit while sleeping. These pests are most active at night, using a person’s warmth and breath to find a host. In addition to heat and CO₂, they’re drawn to natural human scents, especially sweat and worn clothing, which can signal a nearby food source.

Where Do Bed Bugs Hide?

If you’re not spotting the insects but finding other signs of a bed bug infestation, you might be wondering where bed bugs come from. 

• Dark, cluttered areas also attract bed bugs because they provide tight hiding spots close to sleeping areas. 

• Mattresses, bed frames, and the seams of upholstered furniture are ideal nesting locations. 

• Used furniture or clothing that hasn't been properly cleaned can unknowingly bring bed bugs into your home, especially if those items came from infested spaces.

Signs of Bed Bugs

If you’re wondering how to check for bed bugs, here are the top signs to look out for:

• Rust-colored stains or dark spots on sheets, mattresses, or pillowcases (bed bug droppings or blood)

• Shed skins or tiny white eggs in mattress seams, bed frames, or crevices within furniture

• Live bed bugs (reddish-brown, oval, the size of an apple seed)

• Itchy, red bites, often in lines or clusters

• Musty or sweet odor in heavily infested areas

How to Get Rid of a Bedbug Infestation

DIY bed bug removal requires a thorough and persistent approach. Start by deep cleaning all affected areas, especially bedrooms. Wash and dry all bedding, linens, curtains, and clothing on the highest heat setting. Use a stiff brush to scrub mattress seams and vacuum the area regularly, including cracks, baseboards, and furniture crevices. Immediately dispose of vacuum bags or clean canisters to prevent re-infestation.

For more serious infestations, it’s best to call a licensed pest control professional. Exterminators may use a combination of treatments, including heat treatment for bed bugs, insecticides, heat or steam to eliminate bed bugs at all life stages. DIY methods like mattress encasements and intercept traps can help monitor progress, but professional intervention from a local bed bug exterminator is often the most reliable way to completely eradicate bed bugs.
