Signs

Rusty or dark spots on sheets, shed skins, a musty odour and bite marks that appear in rows.

First steps

Hot-wash bedding, vacuum seams and the frame, reduce clutter and use a bed-bug-proof encasement.

Professional help

Infestations usually need professional treatment. Public-health guidance stresses an integrated approach rather than a single product.

What to do first

Do not move infested items to other rooms.
Wash bedding hot and dry it on high heat.
Vacuum seams, frame and surroundings, then empty the vacuum outside.
Fit a zipped bed-bug-proof cover.
Call a licensed pest-control professional.

Why self-treatment often fails

Bed bugs hide in cracks, frames and nearby furniture, so treating only the mattress leaves survivors. Professional treatment usually combines inspection, targeted treatment and follow-up visits.

Prevention while travelling

Check hotel mattress seams with a torch, keep bags off the bed and on a luggage rack, and wash and heat-dry clothes on return. These simple habits cut the chance of bringing bed bugs home. If you find signs at home, act quickly, because early infestations are much easier to treat.

Detailed guidance

Bed bugs are small, flat insects that hide in seams, bed frames, headboards and nearby furniture and come out at night to feed. Signs include rusty or dark spots on sheets, shed skins, a sweet musty odour and bite marks in lines. They are not known to spread disease, but they are distressing and can disturb sleep.

Before calling anyone, avoid moving items between rooms, and do not use household chemicals such as kerosene or bleach, which are dangerous and ineffective. Wash and heat-dry bedding, vacuum seams and frames and seal the vacuum contents in a bag outdoors. Fit a zipped bed-bug-proof encasement to the mattress. Because bugs hide widely, an integrated approach, with inspection, clutter reduction, physical barriers and, where needed, carefully applied treatment by a licensed professional, works best. Follow up after treatment to confirm they have gone.

Common mistakes and checks

The costliest mistake is throwing the mattress out too soon. Dragging an infested mattress through the home spreads bugs to new rooms and the stairwell. Seal it where it is, label it, and speak to a licensed pest professional first.

The second is relying on sprays bought for other insects. They can scatter bugs and rarely reach hiding places in seams, frames and wall sockets. Professional heat or approved treatment, combined with careful laundering, has a better record.

The third is stopping once the bites stop. Bugs can survive for months without feeding, so continue to inspect seams, bed legs and nearby furniture for several weeks. A zip-around encasement rated for bed bugs can trap survivors, and reduces the places they hide. Tell neighbours and building management early so the whole building can act together.

Quick checklist

Seal and label the mattress where it is before moving it.
Call a licensed pest professional.
Wash and heat-dry bedding on the hottest setting it allows.
Inspect seams, bed legs and nearby furniture for weeks.
Use a bed-bug-rated zip encasement.
Tell neighbours and building management early.

Worked example (illustrative)

A traveller finds rusty spots in the seam of a hotel mattress and wonders whether bed bugs have come home. She washes everything hot, vacuums seams, fits a zipped cover and calls a licensed pest-control firm, which inspects the room and nearby furniture. Treating only the mattress would have left insects in the bed frame.
