Secondhand items — especially used mattresses and upholstered furniture — are one of the most common ways bed bugs enter a home. You don’t have to give up thrifting, but you should inspect every used item before buying and heat-treat or quarantine it before it crosses your threshold.
Key Takeaways
- Used upholstered furniture and mattresses are the highest-risk items — avoid curbside finds entirely.
- Inspect before you buy — check seams, tufts, cracks, and undersides with a flashlight.
- Hot-dry used clothing and fabrics immediately — 30 minutes on high heat kills bugs and eggs.
- Quarantine hard items (books, decor, electronics) by sealing or heat-treating before use.
- When in doubt, pass. No deal is worth a months-long infestation.
Why secondhand items are a top way bed bugs spread
Bed bugs don’t fly or jump — they spread by being carried, and used furniture is a perfect vehicle. The U.S. EPA specifically warns against taking discarded furniture, especially items left at the curb, because they may have been thrown out precisely because of bed bugs (EPA: Protecting Your Home from Bed Bugs). An upholstered chair or mattress offers exactly the dark seams and crevices bed bugs love, and a single hidden female can start an infestation.
The risk scales with how good the item is at hiding bugs:
- Highest risk: mattresses, box springs, upholstered sofas and chairs, recliners.
- Moderate risk: wooden furniture with joints and cracks, drawers, picture frames.
- Lower risk: clothing and fabrics (easy to heat-treat), smooth hard items.
How to inspect a secondhand item before buying
Bring a flashlight and look carefully, especially on soft furniture:
- Seams, piping, and tufts of cushions and mattresses — the classic harborage.
- Cracks and joints in wooden frames, and the undersides and back panels.
- Drawer runners and screw holes in dressers and nightstands.
- What to look for: live bugs (apple-seed sized, reddish-brown), pale shed skins, tiny white eggs, and dark ink-like droppings or smears.
If you find any of these signs, walk away. For details on what bed bugs and their traces look like, see how to check for bed bugs.
How to treat secondhand items before bringing them inside
Even after a clean inspection, treat used items as a precaution:
- Clothing, linens, curtains, soft toys: straight into a hot dryer for at least 30 minutes. Heat kills all life stages (University of Minnesota Extension: Bed Bugs).
- Small hard items (books, decor, electronics): seal in a bag and heat-treat in a bed bug heat box, or quarantine in a sealed bag for several months.
- Furniture: vacuum thoroughly (seams, crevices, undersides), then steam upholstered pieces or treat with a desiccant dust in cracks. Quarantine in a garage or non-bedroom space and re-inspect before moving it in.
- Used mattresses: honestly, skip them. If you must keep one, encase it in a bed bug mattress cover to trap anything inside.
If something slips through and you end up with an infestation, work through the complete plan to get rid of bed bugs.
Frequently Asked Questions
Can you get bed bugs from thrift store clothes?
It’s possible but low-risk and easy to neutralize: run thrifted clothes through a hot dryer for 30 minutes before wearing or storing them. Heat kills any bugs or eggs.
Is it safe to buy used furniture?
Yes, if you inspect and treat it. Avoid curbside and free-pile furniture entirely, inspect store or marketplace pieces carefully, and vacuum/steam/quarantine before bringing them indoors. Used mattresses and heavily upholstered pieces carry the most risk.
How long can bed bugs survive in stored furniture?
Months. Adult bed bugs can survive long stretches without feeding, especially in cool conditions, so an item that’s been in storage isn’t automatically safe. Inspect and treat regardless of how long it sat.
What used items should I never buy?
Curbside or “free” upholstered furniture and used mattresses top the list — they’re frequently discarded because of bed bugs. The risk usually isn’t worth the savings.
