The short answer
They can, but carpet is not their first choice. Bed bugs prefer tight, dry gaps close to where people sleep, such as mattress seams and bed frame joints. When numbers grow they also hide along the edges of carpet, under the gripper rod by the skirting, and under rugs near the bed. Vacuuming edges helps; it does not clear an infestation.
If you have found bed bugs in the bed, it is natural to look at the carpet and wonder whether the whole floor is affected. The answer is more reassuring than people fear, but carpet does matter, especially at the edges.
Where bed bugs prefer to live
Bed bugs feed on people and then hide somewhere close, dark and tight, where their flat bodies touch surfaces above and below. That is why the first places they settle are almost always:
- the seams, piping and labels of the mattress,
- the joints and screw holes of the bed frame or divan base,
- the back of the headboard,
- cracks in bedside furniture.
The open pile of a carpet in the middle of the room is not a natural home for them. They do not burrow into it the way carpet beetle larvae or fleas live in it.
Where carpet does come in
As an infestation grows and the best spots fill up, bed bugs spread out from the bed. Carpet then becomes part of the picture in a few specific places.
The edge of the room
Most fitted carpet is held by a wooden gripper rod with tacks, running along the bottom of the skirting board. The gap between the carpet edge, the gripper and the skirting is exactly the kind of tight, dark crack bed bugs like. The edge behind and beside the bed is the most likely place to find them on a carpeted floor.
Under rugs and runners
A rug beside the bed creates a sheltered layer on top of the floor. Bugs moving between the bed and the skirting can stop underneath.
Where furniture sits on the carpet
Bed legs, chair feet and the underside of a sofa base are all places where carpet and furniture meet, and bugs can shelter in the join.
What this means in a Newcastle home
Many Tyneside flats and older terraces in Newcastle have carpet laid over floorboards. Bed bugs sheltering at the carpet edge can follow the gaps between boards and along the skirting, and in an upper flat those boards are part of the floor shared with the flat below. That is one reason a technician treating a Tyneside flat pays attention to the edges of the room, not only the bed. Our inspection page covers what they check.
How to check your carpet
- Start at the skirting board behind the bed and work outwards.
- Fold back the carpet edge a little if it lifts easily, and shine a torch into the gap at the gripper rod.
- Lift any rug near the bed and check underneath and along its binding.
- Look for the same signs you would on a mattress: black dots, pale skins, tiny white eggs, or live bugs.
You may not find anything in the carpet even when the bed is affected. That is normal in an early infestation.
What helps, and what does not
Vacuuming
Vacuuming the carpet edges, the skirting and around the bed legs picks up some bugs and eggs and is a useful step while you wait for treatment. Use the crevice tool along the edge. Empty the vacuum straight away into a sealed bag and put it in an outside bin, so you do not carry bugs around the house.
Vacuuming will not clear an infestation, because it cannot reach the bugs deep in the bed frame or behind the skirting.
Steam
Professional steam treatment is often used along carpet edges and on upholstered furniture during a spray course. Domestic steamers vary a lot in how hot the steam is at the nozzle, so leave this to the technician.
Throwing out the carpet
Almost never needed. Ripping up carpet scatters bugs and eggs into other rooms and costs far more than treating it. A technician can treat the edges where bugs hide.
Shop sprays and powders
Not recommended. They rarely reach the places bugs hide and can push them into new areas.
How treatment covers the floor
A spray course usually includes the edges of carpets and the skirting boards in treated rooms. Heat treatment raises the temperature of everything in the room, including the carpet and the gaps under it, which is one of the reasons it suits rooms where bugs have spread beyond the bed. Typical costs for both are on our price guide.
Before a spray visit, you will usually be asked to clear the floor around the bed so the technician can reach the edges, and not to vacuum the treated edges for a while afterwards. Follow the sheet you are given.
The short version
Carpet is a secondary hiding place, not the main one. Check the bed first, then the edges of the room. If you find signs in the carpet edges, the infestation has probably been there a while, and it is time for professional treatment.
