Can Bed Bugs Live in Carpets or Duvets?
Short answer: yes, bed bugs can hide in carpets and duvets — but not in the way many people imagine. Bed bugs don’t live deep in fibres like clothes moth larvae; they tuck themselves into tight seams, edges and stitching where they can stay close to a sleeping host. If you suspect activity around floors or bedding, it’s important to act methodically and use solutions that treat the whole room, not just the obvious spots.
We understand how frustrating this can feel, especially when bites continue despite washing and cleaning. ThermoPest are UK specialists in bed bug heat remediation; our bed bug heat treatment process is designed to reach hidden harbourages that sprays and DIY measures typically miss.
What people believe vs reality
Belief: “They live in the carpet pile and duvet filling.”
Reality: Bed bugs prefer tight gaps: carpet edges and gripper rods, along skirting boards, under the bed, inside furniture joints, and the stitched seams of duvets, mattress piping and labels. They’ll venture out to feed, then retreat to these crevices.
Belief: “If I shampoo the carpet and wash my duvet, they’ll be gone.”
Reality: Cleaning helps reduce numbers, but it rarely reaches all harbourages or eggs. Infestations persist when any cool, sheltered spots remain untreated.
Science-backed facts about carpets and duvets
- Bed bugs favour harbourages within a couple of metres of where people rest; carpet edges beneath or beside beds and sofas are common.
- Along carpet perimeters, bugs hide under edging, underlay, and tack strips where vacuum suction and shampoo heat don’t penetrate.
- In duvets, they shelter in seams, stitching, buttons and labels; eggs are glued to rough fabric surfaces and are the most heat-resilient life stage.
- To be reliably lethal, heat must be even and sustained. See what temperature kills bed bugs for the science behind critical temperatures.
Common mistakes that keep infestations going
- Spraying the carpet surface while ignoring skirting voids, bed frames, divan bases and plug/screw holes where bugs actually harbour.
- Relying on foggers or aerosols; they don’t penetrate crevices and can scatter insects to new hiding places.
- Washing duvets on a cool or short cycle; eggs can survive sublethal temperatures and brief exposure.
- Moving items between rooms, which spreads the problem and complicates treatment.
Practical steps you can do safely
- Launder bedding and duvet covers on a hot cycle and dry on high heat where fabric care labels allow. Bag items in the room and seal before moving to the machine to avoid drop-off.
- Vacuum slowly with a crevice tool along carpet edges, skirting boards, bed frames, and furniture joints. Dispose of vacuum contents in a sealed bag outdoors.
- Lift a small section of carpet edge (if accessible) to inspect the gripper and underlay margins for cast skins and dark spotting.
- Fit tight-fitting mattress encasements and bed leg interceptors to reduce bites while you plan a comprehensive solution.

Why heat treatment is the superior solution
Cold spots are the real enemy
Carpet edges, voids in bed frames and deep seam lines remain cooler during DIY attempts, letting bugs and eggs survive. Professional heat treatment eliminates these cold refuges by heating the entire room volume, not just surfaces.
Sustained, lethal temperature throughout
Industrial heaters and air movement achieve uniform temperatures across the space and inside belongings. This continuous exposure over time is crucial for eggs, which are more tolerant than mobile stages.
Sensors and active monitoring
We use multiple temperature probes to verify the hardest-to-heat sites have reached target levels and been maintained long enough. This is how we remove guesswork and avoid survival pockets.
All life stages, one treatment plan
When done correctly, heat reaches the places sprays and steamers struggle with, killing nymphs, adults and—critically—eggs in seams, skirting voids and carpet perimeters. Learn more about our bed bug heat treatment and how it integrates with practical prevention.

FAQ’S
Question: Do bed bugs actually live in carpets?
Answer: They don’t nest inside carpet fibres; they hide along edges where the carpet meets skirting, under the gripper/tack strip, and in nearby cracks. From there they travel to feed and retreat again. A slow vacuum with a crevice tool along perimeters helps reduce numbers, but it won’t reach all harbourages or eggs. In professional practice, whole-room heat ensures those edge voids are brought to lethal temperature without cold spots remaining.
Question: Can bed bugs live in my duvet or duvet cover?
Answer: They can shelter in stitched seams, piping, buttons and labels on duvets and covers, but they’re less likely to live deep inside the filling. Washable bedding should be laundered hot and dried on high heat if the care label permits, as brief warm cycles may not affect eggs. Keep items bagged from room to machine to avoid dropping insects en route. In professional practice, heat treatment complements laundering by treating the room and furniture the bedding sits on.
Question: What temperature is needed to kill bed bugs in bedding and carpets?
Answer: Bed bugs and their eggs require sustained exposure to high heat; short bursts or uneven warmth leave survivors. Household washing at 60°C followed by thorough hot drying is effective for suitable textiles, but this doesn’t address carpet edges, bed frames and skirting voids. Whole-room treatment holds the environment at lethal levels long enough for heat to penetrate seams and gaps. In professional practice, multiple sensors confirm targets are met to avoid cold spots.
Question: Will vacuuming and washing get rid of an infestation?
Answer: They’re useful for reduction, not eradication. Vacuuming misses insects in deep cracks and eggs glued to rough surfaces, and washing only treats washable textiles. Use vacuuming and hot laundering as part of preparation, then choose a method that treats the entire room volume. In professional practice, heat treatment provides the consistent, egg-lethal temperatures that DIY rarely achieves.
Question: Why do bed bugs seem to come back after treatment?
Answer: It’s usually either survivors from cold spots or a reintroduction (e.g., from luggage or shared seating), not the bugs “hiding in the carpet pile.” Chemical-only approaches can struggle with egg resilience and resistance, and uneven heating leaves pockets of survival. Post-treatment interceptors and periodic inspections help confirm clearance and catch any new introductions early. In professional practice, monitoring is standard to verify success and prevent setbacks.
