A great deal on a used dresser can turn into an expensive mistake. Secondhand sofas, mattresses, and dressers are a leading way bed bugs get into homes, and they rarely advertise themselves. The fix is a habit, not a gadget. Spend five minutes with a flashlight checking seams, joints, and crevices before the piece comes inside, and you catch the problem at the door instead of in your bedroom two weeks later.
Quick answer
Inspect used furniture outside before bringing it in: with a flashlight, check every seam, joint, cushion fold, crevice, screw hole, and drawer cavity. Look for live reddish-brown bugs, dark pepper-like specks, shed skins, and tiny white eggs. Then wash removable fabric on high heat and vacuum the piece thoroughly.

Why secondhand pieces carry so much risk
Bed bugs travel by hitchhiking, and furniture hands them everything they want. Deep seams, hollow joints, cushion folds, dark interior cavities. A piece can look spotless on the surface and still hold bugs and eggs you'll never spot from across the room.
Upholstered items and mattresses sit at the top of the danger list. Their soft, layered build offers endless places to hide. But don't assume wood is safe. The cracks, screw holes, and joints in a dresser or bed frame are classic harborage too.
Know what you're looking for first
Inspecting blind doesn't help, so learn the signs before you go. A live bed bug is flat and reddish-brown, roughly the size of an apple seed. Freshly hatched nymphs are far smaller and paler, which makes them easy to miss.
You won't always find live bugs, even on an infested piece. So look for what they leave behind. Dark fecal specks like ground pepper, small rusty blood smears, pale translucent shed skins, pinhead white eggs tucked into crevices. Any one of those tells you the furniture is or recently was infested.
- Live bugs: flat, reddish-brown, apple-seed sized
- Dark fecal specks that look like ground pepper
- Pale shed skins wedged into seams and joints
- Tiny white eggs clustered in crevices
Checking sofas, chairs, and mattresses
Bring a flashlight. A thin card helps too, dragged along seams to flush hidden bugs into the open. Pull every cushion and check both faces, then work the seams, the piping, and the tufts. Those tight folds are exactly where bed bugs like to wedge in.
Run your light along the bottom of the frame and the underside of the whole piece. Lift any zippered or stapled fabric panels and look inside. On a mattress, give the seams, the tags, and the box spring corners extra attention. They look completely ordinary at a glance and they hide plenty.
Checking wood and other hard furniture
Wood gets the same scrutiny. Open every drawer and pull it all the way out. Now you can inspect the runners, the back of the drawer, and the empty cavity behind it. All three are easy for bugs to settle into and easy for you to skip past.
Shine your light into joints, cracks, screw holes, and any gap in the construction. If you can tip the piece safely, do it, and check the underside and back panel. Bed bugs gravitate to those spots because they're dark and rarely disturbed.
Free and curbside finds deserve extra suspicion
Be skeptical of anything left at the curb or given away free. A lot of furniture gets discarded for one reason: it was infested. That free sofa can arrive with a costly bed bug problem riding along.
If a curbside piece is too good to walk away from, inspect it harder than you would anything else, and honestly ask whether the savings beat the risk. When you're not sure, leave it. Buying a replacement later costs far less than treating an infestation.
Take a few steps before it comes inside
A clean inspection isn't a guarantee, so build in a buffer before the piece reaches your living space. Anything washable (slipcovers, cushion covers) goes through a hot wash and a high-heat dry. That heat kills bed bugs at every life stage.
Vacuum the whole piece next, working the seams and crevices, then take the bag straight outside and toss it. Already brought something home and now you're second-guessing it? A licensed local pro can inspect and treat the item before bugs spread to the rest of the house.
