Bed Bugs: What Works, And What Makes It Worse

Bed bugs are highly invasive organisms that hide in your bed during the day and come out only at night when you’re fast asleep, to suck blood.

Two things about bed bugs that change how people handle them: they’ve nothing to do with how clean your home is, and almost everything you can buy to treat them yourself will fail.

Bed bugs aren’t a hygiene problem. They’re hitchhikers: they arrive in luggage, on second-hand furniture, or from an adjacent unit. Immaculate homes get them.

The shame attached to this is the main reason people delay calling anyone, and delay is what turns a small infestation into a whole-flat one.

They don’t transmit disease. The bites itch, and that’s the extent of the medical problem.

How to know

Small dark specks along mattress seams, like a fine-tipped pen has been dotted on the fabric. This is the most reliable sign.
Rusty or reddish smears on sheets, from bugs crushed while you sleep.
Shed skins: pale, translucent, bug-shaped.
Live bugs: flat, oval, reddish-brown, about the size of an apple seed. Check seams, the headboard, bed frame joints, and behind the skirting near the bed.
Bites in a line or cluster on skin exposed during sleep: arms, shoulders, legs, neck.

Bites alone aren’t proof. Reactions vary enormously. Some people show nothing at all while sharing a bed with someone covered in bites, and reactions can appear days later. Find the physical evidence before concluding either way.

What not to do

Don’t put infested furniture in the corridor. It spreads them to neighbours, and someone will take it home. If a mattress must go, wrap and seal it and label it clearly.
Don’t move to another room to sleep. It’s the strongest instinct and the worst move. Bed bugs follow the carbon dioxide, and you take the infestation with you into a second room.
Don’t use insect foggers or “bug bombs.” They scatter bugs deeper into walls and adjoining units, rarely reach where the bugs are, and are a genuine fire risk.
Don’t rely on shop sprays. Repeated partial treatment breeds resistance and spreads the population through the flat.

What works

Professional treatment, and usually more than one visit. This is a case where do-it-yourself doesn’t work, and the failed attempts make the professional job harder and more expensive.

What you can do alongside it:

Heat. Wash all bedding and affected clothing at 60°C, then tumble dry hot. For items that can’t be washed, a hot tumble dryer cycle alone will do it.
Seal treated items in bags and keep them out of the room until treatment is finished.
Vacuum thoroughly, then immediately empty the vacuum into a sealed bag and put it outside.
Reduce clutter around the bed, which removes hiding places and makes treatment more effective.
Mattress and pillow encasements after treatment: they trap anything remaining and make future inspection easy.
Pull the bed away from the wall and keep bedding off the floor during treatment.
Tell your neighbours and your management or town council if you’re in a flat. Bed bugs travel between units, and one treated flat beside two untreated ones is a temporary fix.

The bites

Don’t scratch: the main complication is a secondary skin infection from scratching, not the bite itself.
Cool compress, and calamine or a mild steroid cream for itching if a pharmacist advises it.
An antihistamine can help a child sleep through the itch.
Keep nails short.
See a doctor if bites become hot, spreading, weeping or painful, or if there’s any facial swelling or breathing difficulty.

How they arrive

Most infestations come home in luggage, so the check takes two minutes and pays off every time.

On arrival: put luggage in the bathroom, not on the bed. Pull back the sheets and check the mattress seams, the corners, and behind the headboard.
Keep the case on a rack away from the wall, closed, for the stay.
On return: unpack directly into the washing machine and run everything hot, including things you didn’t wear. Tumble dry hot.
Inspect and vacuum the suitcase, and store it away from bedrooms.
Second-hand furniture: inspect seams and joints thoroughly before it comes through the door. Upholstered items and bed frames are the risk.

Frequently asked questions

Do bed bugs mean my home is dirty?

No. They’re hitchhikers that arrive in luggage, on second-hand furniture or from an adjacent unit, and immaculate homes get them. The shame attached is the main reason people delay calling for help, and delay is what turns a small infestation into a whole-flat one.

Are bed bug bites dangerous?

No. They don’t transmit disease. The bites itch, and the main complication is a secondary skin infection from scratching. See a doctor if bites become hot, spreading, weeping or painful.

How do I know if I have them?

Look for small dark specks along mattress seams, rusty smears on sheets, shed skins, and live bugs about the size of an apple seed in seams, the headboard and frame joints. Bites alone aren’t proof. Some people show no reaction at all while sharing a bed with someone covered in them.

Should I sleep in another room?

No, and this is the strongest instinct and the worst move. Bed bugs follow carbon dioxide, so you take the infestation into a second room with you.

Can I treat them myself?

Realistically no. Professional treatment, usually over more than one visit, is what works. Failed shop-spray attempts breed resistance and spread the population, making the professional job harder. What you can do is use heat: wash bedding at 60°C and tumble dry hot.

How do I avoid bringing them back from a hotel?

Put luggage in the bathroom, not on the bed, check the mattress seams and behind the headboard, and keep the case closed on a rack away from the wall. On return, unpack straight into the washing machine and run everything hot, including unworn items.

The main points

Not a cleanliness problem, and not a health risk beyond the itching. The shame is what causes the delay.

Don’t put furniture in the corridor, don’t move to another room, and don’t use bug bombs.

Call a professional, and do the heat washing alongside: 60°C and a hot tumble dry.

And check the mattress seams in every hotel room. That’s how they get home.
