Second-Hand Furniture and Bed Bugs: What to Check in London

A good second-hand find can save money. It can also bring an unwanted guest home. Bed bugs hide in seams, joints and fabric folds, so a bargain sofa or bed frame deserves a careful look before it crosses your front door.

This guide covers how to check used furniture, what to be wary of when buying from marketplaces and charity shops, and how to get rid of an infested piece without spreading the problem.

What the NHS advises

The NHS is clear on this point. It says that you should not bring second-hand furniture indoors without carefully checking it first. It also lists the signs to look for, including small brown spots on bedding or furniture, which are bed bug droppings.

Adult bed bugs are around 5mm long and dark yellow, red or brown. Because they are small and flat, they slip into very narrow gaps. A quick glance at the top of a cushion will therefore miss most of them.

Check it before you buy

Whenever you can, inspect an item where it is, in good light. Use a torch and a stiff card, such as an old loyalty card, to run along seams and joints. Look for live bugs, shed skins, tiny pale eggs and dark spotting.

Focus on the places bed bugs like best:

• mattress seams, piping and labels
• the joints and slats of bed frames and headboards
• under sofa cushions, along zips and beneath the dust cover
• the backs of drawers, wardrobe corners and screw holes

Any sign at all is a reason to walk away. Because one bug can mean many more out of sight, do not talk yourself into a discount. Similarly, if the seller will not let you look closely, treat that as a warning. Our guide to how to check a London flat for bed bugs shows the same method in a rented room.

Marketplaces, charity shops and street finds

Marketplace listings are the hardest to judge. Photos rarely show seams, and a seller may not know the history of the item. Ask where it was kept, and whether anyone has had bites. Then inspect it outside the seller’s home, not in a bedroom.

Charity shops often keep furniture in a back room beside other donations. Ask staff whether upholstered items are checked, and look for tags that say how items are handled. Even so, you still need to do your own inspection before it goes into your car.

Never take furniture left on the pavement. It may have been dumped for exactly this reason. Moreover, bringing it indoors puts your whole home at risk for the sake of a free chair.

What to do if you are unsure

Sometimes you cannot tell. The light is poor, the item is dark fabric, or the seller is in a hurry. In that case, the safest choice is simply to say no. Cheap furniture is not a bargain if it leads to weeks of treatment.

If you already bought the piece, keep it outside or in a hard-floored hall while you decide. For example, a garage, a balcony or a covered yard works well. Meanwhile, photograph any marks you find and keep the receipt, because both help if you need to raise a complaint with the seller.

Bringing a find home safely

If you do buy, plan the journey. Wrap the item in plastic sheeting or a large bag at the seller’s door, and load it so that it does not touch your own bedding or coats. Then keep it outside, or in a hard-floored area, until you finish a second, slower inspection.

Do not put a second-hand mattress straight into a bedroom. If you suspect trouble, hold off on using the item and read about what to do if you think you have bed bugs yourself. Our guide to the London bed bug treatment process explains what professional help involves.

Disposing of infested furniture properly

If you find bed bugs in a piece of furniture, do not leave it on the street. GOV.UK defines fly-tipping to include one or two pieces of furniture, and it can spread the problem to neighbours. It also says that if you hire someone to take your waste, you should check they are a registered waste carrier.

The safer route is your council’s bulky waste service. Seal the item in plastic before you move it, and label the wrapping so that crews know to handle it with care. Then book a collection, and ask the service whether they need to know about the pests.

Council rules vary, so check your own page before booking. Four examples show the differences when checked in October 2026:

• Lambeth takes mattresses and furniture, with items put out between 8pm the night before and 6am on collection day.
• Brent collects mattresses (maximum two) and furniture, and items must be out by 7am.
• Sutton collects up to six items per booking, and items must be outside by 6am.
• Redbridge lists one free collection every 12 months for up to three items.

None of those pages mentioned bed bugs when we read them. Therefore contact the service directly before collection day. Find your council through GOV.UK if you are unsure which one covers your address.

Local guidance by borough

Where you live shapes the disposal route. Residents can read what Lambeth households should know, the Redbridge area guide, bed bug guidance for Sutton and advice for Brent renters for local contact points.

Shops, landlords and short lets

Furnished lets and holiday flats buy a lot of second-hand pieces. Owners should inspect each item and keep a record, as our guide for hotels and short lets explains. Because guests move in and out quickly, one bad sofa can affect many stays.

Treatment choices also affect furniture. Our post on heat or insecticide for bed bugs explains how each route handles sofas and mattresses. After any new purchase, a monitor under the bed legs gives early warning, as our post on bed bug monitors and interceptors describes.
