Bed bugs do not appear out of nowhere. They usually arrive because people, belongings, or secondhand items bring them inside. Bed bugs then settle near your sleeping and resting areas.
If you know the common entry points and hiding spots, you can spot an infestation earlier and take action to stop it from spreading.

Bed bugs move with you and your belongings. Travel, used furniture, or shared living spaces often start the problem, and the insects hide in cracks, seams, and soft furnishings.
How Bed Bugs Get Into a Home

You usually bring bed bugs inside on something, and then they spread from room to room. Travel, secondhand items, and nearby units in multifamily buildings are the most common ways they enter.
Travel and Luggage as the Most Common Entry Point
Bed bugs often latch onto luggage, backpacks, purses, or clothing after you stay in hotels, motels, dorms, or other crowded places. Orkin and New York State both list luggage and bags as common ways bed bugs enter a home.
A quick suitcase inspection after a trip can help you prevent bed bugs from spreading into your bedroom. Keep bags off beds and floors when you travel, and wash worn clothing promptly after returning home.
Used Furniture, Mattresses, and Upholstered Items
Used furniture, especially upholstered pieces, mattresses, box springs, and couches, often brings bed bugs into homes. Bed bugs hide in seams, tufts, and hidden joints, so a piece can look clean but still carry live bugs.
If you bring in a thrifted chair or sofa, inspect seams, zippers, and undersides before it enters your home. This can help you avoid bringing bed bugs inside.
How Bed Bugs Spread Between Apartments and Nearby Rooms
In apartments, hotels, and attached homes, bed bugs move through wall voids, electrical openings, and shared structural gaps. An infestation in one unit can quickly become a problem in another when insects travel for new hiding places and feeding opportunities.
Early treatment, careful monitoring, and sealing obvious gaps can help prevent bed bugs from spreading farther once they arrive.
What Actually Attracts Them Once They Arrive

Once bed bugs are inside, they look for people, not mess. Their activity depends on body heat, carbon dioxide, and protected hiding places close to where you sleep.
Why Warmth, Carbon Dioxide, and Sleeping Areas Matter
Bed bugs, or cimex lectularius, are drawn to the carbon dioxide you exhale and the warmth your body gives off while you sleep. They tend to come out at night and stay close to resting areas.
They are not attracted to food crumbs or garbage like some pests. They are drawn to you, which is why bedrooms and couches often become the center of activity.
Why Clutter Helps but Dirt Does Not Cause Infestations
Clutter gives bed bugs more places to hide, making them harder to spot and treat. Piles of clothes, stacked boxes, and crowded storage spaces create more shelter for movement and egg-laying.
Even a spotless home can develop a problem if bugs arrive on travel items or furniture.
Where They Hide Near Beds and Resting Areas
Bed bugs favor box springs, bed frames, and mattress seams, plus cracks near headboards, nightstands, and baseboards. They hide in crevices around beds and come out to feed on humans at night.
If you inspect near sleeping areas, focus on tight seams, screw holes, and folded fabric edges. Those hidden spaces are where activity often starts.
Signs You May Already Have Them

The earliest clues are often visual. Live bugs, tiny eggs, dark droppings, and unexplained bites can all point to activity nearby.
How to Spot Live Bugs, Eggs, and Droppings
Common signs of bed bugs include rusty or dark spots on bedding, shed skins, tiny white eggs, and black specks of excrement. Bed bugs are small and flat, so they often hide until you move bedding or shine a light into seams.
If you notice several signs, check the mattress edge, box spring, and nearby furniture right away.
What Bedbug Bites Can and Cannot Tell You
Bedbug bites can be itchy and may appear in clusters or lines, but bites alone do not confirm the pest. Some people react strongly, while others show little or no skin response.
Bites are a clue, not a diagnosis. You still need to inspect hiding places to know whether bed bugs are present.
How to Find Bed Bugs in Common Hiding Places
Start with the bed, then check upholstered furniture, baseboards, seams, and clutter near sleeping areas. Use a flashlight and look for live insects, dark spots, shed skins, or eggs tucked into narrow gaps.
A slow, careful inspection works better than a quick glance. Bed bugs are small, flattened, and excellent at staying out of sight.
What To Do If You Confirm Activity

Once you confirm bed bugs, you need to slow their spread and treat the full infestation, not just the visible bugs. Acting early makes pest management more effective.
Early Steps to Limit the Spread
Strip bedding carefully, seal washable items in bags, and launder them on high heat if possible. Vacuum seams, cracks, and surrounding floors, then empty the vacuum outdoors right away.
Move the bed slightly away from the wall if you can, and reduce clutter around sleeping areas. These steps can help prevent bed bugs from moving into more rooms while you plan next steps.
When DIY Efforts Are Not Enough
DIY methods often miss hidden bugs in tiny crevices, which is one reason infestations return. The EPA recommends integrated pest management, which combines several methods instead of relying on one fix.
If you keep seeing live bugs, new bites, or fresh droppings after cleaning and vacuuming, the problem is probably larger than it looks. At that point, home-only efforts may not be enough to get rid of bed bugs.
When to Call a Pest Control Professional
A licensed pest control company or professional exterminator can inspect the whole area and identify where the bugs are hiding. They will build a targeted pest management plan.
Orkin and Cornell IPM both say that professional help is often the most effective option for stubborn infestations.
Call as soon as you confirm activity in more than one room or in an apartment building. Contact a professional if you find bugs in hard-to-reach furniture.
The faster you bring in help, the easier it is to stop the spread.
