How to Check Used Furniture for Bed Bugs Before You Bring It Home
Secondhand furniture is a top way bed bugs enter homes. A step-by-step inspection for couches, mattresses, frames, and dressers — and what to do if you already bought it.
Secondhand and curbside furniture is one of the most common ways bed bugs move into a home that never had them. A great deal on a couch or a free dresser from the curb can come with a very expensive stowaway. The good news: a careful ten-minute inspection before anything crosses your threshold catches the overwhelming majority of problems.
Why used furniture is such a common entry point
Bed bugs spread by hitchhiking, and upholstered and wooden furniture offers exactly the tight, dark seams and joints they love to hide and lay eggs in. A piece that sat in an infested home can carry bugs and eggs for months. Curbside finds are especially risky — furniture is frequently put out because it was infested, which is why you should be deeply suspicious of "free" mattresses and couches on the sidewalk.
Before you go: bring the right tools
A quick kit makes inspection far more reliable:
- A flashlight (your phone works) to throw raking light across seams
- An old credit card or putty knife to drag along seams and flush bugs out
- A flashlight + your eyes, and ideally a small magnifier for eggs
- Disposable gloves if you're handling questionable pieces
What you're looking for
The same evidence that confirms an infestation anywhere: live bugs (flat, reddish-brown, ~5 mm ovals), dark ink-like fecal spots, rust-colored stains, pale shed skins, and tiny pearly-white eggs cemented into crevices. Any of these is a hard no.
How to inspect each type of furniture
Upholstered furniture (couches, chairs)
This is the highest-risk category. Check:
- All seams and piping, running the card along them and watching for bugs or spotting
- Under and between cushions, and the cushion zippers
- The underside — flip it over and inspect the frame, staples, and the dust cover (peel a corner back)
- Tufting, buttons, and folds where fabric bunches
Mattresses and box springs
Honestly, the safest advice is don't buy a used mattress — they're nearly impossible to fully inspect and treat. If you must, check every seam, the piping, the tufts, and lift to inspect the underside and the box-spring frame. A single dark-spotted seam means walk away.
Wood furniture (frames, dressers, nightstands)
- Joints, screw holes, and cracks — bed bugs wedge into these
- Drawer runners and the undersides of drawers
- Corners and any place two pieces of wood meet
- Pull drawers all the way out and inspect the cavity
If you already brought it home
Don't panic, but act before it settles in:
- Quarantine it — ideally keep it in a garage or non-carpeted entry, away from bedrooms, until you've treated it.
- Vacuum thoroughly, including all seams and crevices, then dispose of the vacuum contents in a sealed bag outside.
- Heat what you can. Removable fabric covers and small soft items can go through a hot dryer. Professional heat treatment is an option for valuable pieces.
- Steam seams and crevices (heat above ~120°F kills bugs and eggs on contact).
- For wood pieces, treat cracks and joints, and consider a desiccant dust in voids per its label.
- Set interceptor traps near where the piece now sits to monitor for any activity over the following weeks.
The simple rule
Inspect before it enters — seams, undersides, joints, and crevices, with a flashlight and a card — and be ruthless about walking away from curbside mattresses and upholstered pieces with any spotting. Ten minutes of inspection is a lot cheaper than a whole-home infestation, and it's the single best habit for anyone who shops secondhand.
