How to Check Used Furniture for Bed Bugs Before It Comes Inside
Inspect a used couch, mattress or dresser outside, before it comes through the door. Pull the cushions, run a card down every seam, tip the piece over and look at the underside and the joints. You are looking for four things: live insects, dark ink like spots, pale shed skins, and eggs about a millimeter long.
Secondhand furniture moves constantly around Stark and Summit County. Estate sales, moving sales, campus turnover near Kent and Akron, curb finds on trash night, a dresser someone posts online for nothing because they want it gone by Sunday. Most of it is fine. The check below takes about ten minutes, and it is the difference between a good find and a problem that ends up in the bedroom.
Can Bed Bugs Really Come In On A Used Couch?
Yes, and furniture is one of the main ways they travel. The EPA describes bed bugs as great hitchhikers that move from an infested site into a new home on furniture, bedding, luggage, boxes and clothing. Its guidance to homeowners is direct: do not bring second-hand furniture into your home unless you have thoroughly inspected and cleaned it first.
What makes them easy to miss is the shape. Ohio State University Extension describes the adult as brown to reddish brown, oval, flattened, and 3/16 to 1/5 inch long. Flattened is the word that matters. An insect built like that sits inside a mattress seam, a screw hole or the gap where a drawer runner meets the frame, and a quick glance across a piece of furniture will not turn it up.
The arithmetic is the other reason to look carefully. OSU Extension puts egg laying at up to five a day, and as many as 500 over a female's lifetime, with eggs about 1/32 of an inch long and cemented into hiding places. A couple of insects riding in on a nightstand is not a couple of insects for long. If you are trying to work out what you found, our bed bug identification guide has photos.
What Does The Evidence Actually Look Like?
Four kinds of evidence, and you rarely find the insects first. The EPA describes the signs this way:
| Sign | What you are seeing | Where it shows up |
|---|---|---|
| Dark spots | Bed bug excrement. The EPA notes it may bleed into fabric the way a marker would. | Piping and seams, around tags, in cracks of a frame or headboard |
| Shed skins | Pale yellow casings that nymphs leave behind as they grow. They hold their shape, so they look like empty insects. | Folds, cushion edges, screw holes, drawer joints |
| Eggs and eggshells | About a millimeter, pale, stuck in place rather than loose. Easy to mistake for a fleck of something. | Tight seams, the underside of webbing, rough unfinished wood |
| Live bed bugs | Brown to reddish brown, oval and flat, up to about a fifth of an inch (OSU Extension). | Deepest point of any seam or crevice, usually where two materials meet |
A clean look is good news, not proof. The EPA points out how small the hiding places are, and a flat insect inside a screw hole is genuinely hard to see in a driveway at dusk. Treat a clear inspection as a reason to accept the piece, then keep it isolated for a few weeks rather than putting it straight into a bedroom.
The Ten Minute Check, Piece By Piece
Bring a flashlight, an old credit card or putty knife for running down seams, and gloves. Do all of it outside. Photograph anything you are unsure about, because a photo zoomed in beats a squint.
- Upholstered chairs and couches: take every cushion out and check both sides, then the deck underneath, the piping, the zipper channels, and the staples and webbing on the underside once you tip it over.
- Mattresses and box springs: work the piping the whole way around, lift the tags, and look at the corners first. On a box spring, the gauze underneath hides more than the top ever does.
- Wood dressers and nightstands: pull every drawer all the way out and look at the runners, the screw holes, the joints and the raw unfinished wood inside the case. That interior is rougher than the finished surface and holds evidence better.
- Bed frames and headboards: check every joint, bolt hole and crack, and take a fabric headboard apart at the seams if you can.
- Anything with a hollow space: recliner mechanisms, hide-a-beds, the backs of cabinets, and the cavity behind a stapled dust cover.
- Ask where it has been: a piece out of a storage unit, a rental turnover or a house being cleared is worth a slower look than one from a garage.
What If It Is Already In The House?
Do not drag it back through the living room. Move anything you suspect in sealed plastic bags, which is what the EPA recommends for carrying items between areas, so nothing falls off along the way.
For the parts that can take heat, the EPA is specific: bedding and clothing put through a dryer on high for 30 minutes will kill bed bugs, and washing alone generally will not. That covers cushion covers, blankets, curtains and soft goods. Items that cannot be treated go into a sealed bag or container, and the EPA says to leave them there for up to a year to be sure anything alive inside is dead. If you vacuum, seal the vacuum bag as tightly as you can and put it straight into an outdoor trash container.
The EPA also warns that do-it-yourself heat treatments might not work, and notes that professionals have access to more intensive and proven methods, including treating whole houses with heat. A space heater in a closed bedroom does not reach the temperature that matters in the places that matter, and it is a fire risk on top of that.
Which Free Finds Are Not Worth The Risk?
Some pieces cannot be inspected honestly, and those are the ones to leave. A mattress or box spring sitting on a tree lawn is the clearest example, because there is usually a reason it is out there and no way to check the inside of it. The same goes for upholstered furniture you cannot open, anything from a unit you know had a problem, and any piece you are not allowed to tip over or take apart before you commit.
Hard furniture is the safer end of the market. Metal, glass and solid wood that comes apart can be inspected properly and wiped down. Upholstery, foam and anything with a stapled fabric panel is where the risk sits, and that is worth knowing before the truck is loaded.
When Does It Stop Being A Flashlight Job?
When you find live insects or a concentration of spots and skins, or when bites start showing up in a house where a secondhand piece recently arrived. At that point the question is no longer the couch, it is the room around it, and that takes an inspection rather than a guess. Our bed bug treatment starts with a free inspection so you know what you are dealing with before anyone talks about treating anything.
When treatment is needed, heat is our lead method. ThermaLock kills every life stage including the eggs, usually inside a single day, and leaves no chemical residue in a room where somebody sleeps. That matters here, because the eggs are what survives a partial job and restarts the problem a few weeks later. The heat treatment page covers how it works. Bed bug jobs need preparation, so the office talks it through with you before anything is scheduled.
If you brought something home and you are not sure what you found in it, call State Termite at 330-494-6199 or schedule a free inspection. We have been working in Stark and Summit County since 1933, and bed bug inspections are free.
Frequently Asked Questions
Can bed bugs live in wood furniture, or only in mattresses?
Wood is a normal hiding place. The EPA lists cracks in bed frames and headboards among the spots to check, alongside mattress piping, seams and tags. Ohio State University Extension describes the adult as flattened and up to about a fifth of an inch long, which is a shape built for screw holes, drawer joints and the rough unfinished wood inside a dresser case.
Will running cushion covers and blankets through the dryer kill bed bugs?
The EPA says bedding and clothing put in the dryer at high temperature for 30 minutes will kill bed bugs, and that washing alone generally will not. Carry the items there in sealed plastic bags so nothing drops off on the way through the house.
How long can bed bugs survive in furniture that has been sitting in storage?
Long enough that a storage unit is not a safe assumption. The EPA advises sealing items that cannot be treated in a bag or container for up to a year to be certain anything inside is dead, which tells you how patient these insects are without a meal. Inspect a piece out of storage as carefully as one straight out of a bedroom.
I already carried the couch inside. What should I do first?
Stop moving it. Every trip through the house is a chance to leave something behind in a new room. Keep the piece where it is, check it properly in daylight, bag and dry the soft goods on high heat, and get an inspection if you find live insects, dark spots or shed skins. Bed bug inspections are free at State Termite.
Is it ever safe to take a free mattress?
A mattress or box spring left at the curb is the one piece we would tell you to walk past. You cannot inspect the inside of it, the gauze under a box spring hides evidence well, and there is usually a reason it is out there. Hard furniture that comes apart can be checked honestly, and that is a different decision.
