FAQsBed Bugs (Khatmal)

Bed bug bites usually appear in a line or a small cluster on skin that was exposed while you slept, and you find them on waking. Mosquito bites are scattered and you generally notice them as they happen.

Bites alone are not proof — people react very differently, and some do not react at all. Look for physical evidence instead:

• Small dark spots — like a full stop drawn with a fine pen — along the mattress seam, the bed frame joints and the headboard.
• Tiny blood smears on the sheet.
• Shed skins, pale and see-through, in the seams and joints.
• The insects themselves — flat, oval, reddish-brown, about the size of an apple seed when fully grown.

Check the bed frame joints and the mattress seam nearest where the head rests. That is where the evidence appears first.

No. Bed bugs are carried in — they have nothing to do with how clean a home is. They feed on blood, not on dirt or food waste, so a spotless bedroom is exactly as attractive to them as any other.

They arrive on luggage after travel, on second-hand furniture and mattresses, in bags and clothing, and through shared walls and service ducts from a neighbouring flat. Hotels, hostels and hospitals get them for the same reason: many people passing through.

This matters practically, not just emotionally. Households that assume it is a hygiene problem respond by cleaning harder — washing, scrubbing, sometimes throwing out a mattress — none of which reaches insects living inside a bed frame joint or a crack in the wall behind the headboard. The treatment is completely different from cleaning.

Because the eggs survived the first visit. This is normal, and it is why bed bug work is planned as two or three visits rather than one.

Bed bug eggs are protected and hatch roughly one to two weeks later. A single treatment removes the adults and the room seems clear — then the new generation matures and the biting starts again. Anyone promising to finish khatmal in one visit is promising something the insect does not allow.

Three other common reasons:

• Only the mattress was treated. They live in the frame joints, the headboard, bedside furniture and wall cracks — not mainly in the mattress.
• The mattress was moved to another room, which spreads them instead of containing them.
• They are re-entering from next door through shared walls or ducts. In flats this is common and needs the neighbouring unit treated too.

Strip the bed, wash and hot-dry the bedding, and clear access to the bed frame and skirting — but do not start moving furniture and mattresses to other rooms.

Do:

• Wash bedding, sheets and curtains on the hottest wash the fabric allows, then dry thoroughly on high heat. Heat is what kills them, not detergent.
• Bag washed items and keep them sealed until treatment is finished.
• Pull the bed away from the wall so the technician can reach the frame, headboard and skirting.
• Clear clutter from under the bed.
• Vacuum the room, then seal and dispose of the vacuum bag outside immediately.

Do not: move the mattress or bedroom furniture into another room, sleep in a different room to escape the bites, or throw out the bed before treatment. All three spread the problem to a new area — and people who move rooms often find the bugs follow them within a week or two.

Yes. Travel is the most common way bed bugs enter a home in the first place.

They travel in luggage, bags and clothing. A single fertilised female is enough to start a problem, which is why a spotless home can suddenly have them weeks after a trip with no other explanation.

In the room: put the case on the luggage rack or a hard surface, not on the bed or the carpet. Pull back the sheet and check the mattress seam and the headboard for small dark spots. It takes a minute.

Coming home: do not put the case on the bed. Unpack near the door, put everything washable straight on a hot wash and a hot dry, and store the case away from bedrooms.

Heat is what kills them, not detergent. A hot tumble dry does more than washing alone.

Bed bugs can be cleared completely, but never in one visit — the eggs survive, so two or three visits is the honest minimum.

What a complete job covers:

• Bed frame joints, slats and headboard — where they actually live
• Mattress and base seams
• Bedside furniture, skirting behind the bed, cracks in the wall
• Any adjoining room that people have been sleeping in to escape the bites

Your part matters as much as ours. Wash and hot-dry all bedding — heat kills them, detergent does not. Do not move the mattress to another room, and do not start sleeping elsewhere: both spread the problem instead of containing it.

In flats, re-entry from a neighbouring unit through shared walls and ducts is common. If yours keeps returning after a thorough treatment, that is usually why, and the neighbouring unit needs treating too.

Rarely successfully. Bed bugs are one of the few household pests where DIY usually costs more than calling someone, because the failure is slow and expensive.

Two reasons. They hide in places you cannot treat properly — inside frame joints, behind the headboard, in wall cracks — and the eggs survive whatever you apply first, so a home attempt often knocks the numbers down just enough to look like it worked, then rebounds a fortnight later.

What genuinely helps, and is worth doing yourself:

• Wash and hot-dry all bedding, weekly during treatment
• Vacuum the bed area and dispose of the bag outside immediately
• Pull the bed away from the wall
• Reduce clutter around the bed

What to avoid: throwing out the mattress before treatment, moving to another room, and spraying repellent products around the bed, which scatters them into the room.

Realistically three to six weeks, across two or three visits. Anyone promising it in one visit is promising something the insect does not allow.

The timeline follows the egg cycle rather than the treatment:

• Visit 1 — removes the adults and young present. Biting usually stops or drops sharply within days.
• Week 1–2 — protected eggs hatch. Some activity may return. This is expected, not a failure.
• Visit 2 — deals with the new generation before it can breed.
• Week 3–4 — a check visit confirms it is clear.

What makes it take longer: moving the mattress or sleeping in another room, which spreads them; heavy clutter around the bed; and re-entry from a neighbouring flat through shared walls or ducts.

Keep sleeping in the treated room. It sounds counter-intuitive, but moving takes the problem with you and restarts the clock somewhere new.

Almost never. Throwing out a mattress before treatment usually spreads the problem and costs you money for nothing.

Bed bugs live in the bed frame joints, headboard, bedside furniture and wall cracks at least as much as in the mattress. Removing the mattress leaves the population in place and you buy a new one for them to move into.

Carrying an infested mattress through the house or down a stairwell also drops them along the route, which is how a bedroom problem becomes a whole-flat problem.

When replacement is genuinely worth it: the mattress is already old or damaged, or the fabric is torn so the interior cannot be treated. Even then, replace after treatment is complete, not before.

If you do dispose of one, wrap it fully in plastic before it leaves the room and mark it, so nobody takes it home.

Small raised red marks, often in a line or a tight cluster, on skin that was uncovered while you slept — and you notice them on waking rather than as they happen.

Common on arms, shoulders, neck, back and legs. Reactions vary widely: some people develop obvious itchy welts, others barely mark at all, which is why one person in a household can be covered while another notices nothing.

Bites alone are not proof. Confirm it with physical evidence instead:

• Small dark spots along the mattress seam and bed frame joints
• Tiny blood smears on the sheet
• Pale shed skins in the seams
• The insects themselves — flat, oval, reddish-brown, about apple-seed size

For the bites, ordinary antiseptic and antihistamine usually manage the irritation, and a doctor should see anything that becomes infected or causes a strong reaction. Treating your skin does nothing about the room, so deal with both.

Where they are on your body and when you notice them tells you more than how they look.

	Bed bug (khatmal)	Mosquito (machar)	Flea
Pattern	Line or tight cluster	Scattered, random	Clusters of small red dots
Where	Skin uncovered while asleep	Any exposed skin	Ankles and lower legs
When noticed	On waking	As it happens	Soon after, often indoors
Look for	Dark spots on mattress seams	Standing water nearby	A pet, or pet bedding

Reactions vary enormously, so bites alone are never proof. Confirm with physical evidence: dark spots along the mattress seam and bed frame joints for bed bugs, standing water for mosquitoes, and flea dirt in pet bedding for fleas.

See a doctor for any bite that becomes infected or causes a strong reaction. Treating your skin does nothing about the room, so deal with both.

Within about two metres of where someone sleeps, in joints and seams rather than open surfaces.

Where	How likely
Bed frame joints and slats	Very high — check first
Mattress seams, especially at the head end	Very high
Headboard and the wall behind it	High
Bedside furniture, drawer runners	High
Skirting and wall cracks near the bed	Moderate
Curtain hems, upholstered chairs	Moderate
Electrical sockets and picture frames	Lower, but happens in heavy cases

This is why treating only the mattress fails, and why moving to another room takes the problem with you rather than escaping it.

Look for small dark spots like a fine pen mark, pale shed skins, and blood smears on the sheet. Take a photograph if you find anything — it helps confirm identification before the visit.

Whole-room heat treatment is not widely available here, and it is honest to say so rather than advertise it. What works instead is a properly executed multi-visit programme.

Where heat genuinely helps, and you can do it yourself: washing and hot-drying bedding and clothing. Heat is what kills them, not detergent, and a hot tumble dry does more than washing alone.

What a proper treatment covers:

• Bed frame joints, slats and headboard — where they actually live
• Mattress and base seams
• Bedside furniture, skirting and wall cracks near the bed
• Adjoining rooms if anyone has moved to escape the bites
• Two or three visits, spaced to the egg cycle

Be careful with any company advertising a one-visit permanent solution, heat or otherwise. Bed bug eggs hatch after roughly one to two weeks, and no single treatment accounts for that.

Check the bed frame and mattress seams before you assume anything from the bites. Bites alone are unreliable — people react very differently, and some not at all.

What to look for, in order of how conclusive it is:

• Small dark spots on the mattress seams, bed frame joints and behind the headboard — this is the most reliable sign
• Shed skins, pale and translucent, in the same places
• Live insects in frame joints, slats and the mattress piping — about the size of an apple seed
• Small blood spots on the sheet
• Bites in lines or clusters, usually on skin exposed at night

Use a torch and check the joints of the frame and the underside of the slats, not just the mattress surface. They stay tight in dark seams and are easy to miss.

Photograph anything you find. If you are unsure, send the photo before booking — we can usually confirm it, and it avoids paying for treatment you do not need.

No. They spread instead — and the two things people try first usually make it worse.

Bed bugs survive long periods without feeding, so leaving a room unused does not clear it. The population keeps building quietly.

Do not move to another room. This is the most common mistake and it is the main way a one-room problem becomes a whole-house problem. They follow, and now you have two rooms to treat.

Do not throw out the mattress before treatment. It is expensive, it rarely solves anything because they live in the frame and surrounding furniture too, and carrying it through the house spreads them.

What genuinely helps while you arrange treatment: wash and hot-dry bedding, since heat is what kills them; keep sleeping in the same room; and do not spray, which scatters them.

Treatment resolves this reliably in two or three visits spaced to the egg cycle. It is an unpleasant problem, not an unsolvable one.

A visit takes a few hours. The programme takes two to three visits over three to six weeks, and the spacing is not padding — it is the egg cycle.

Why one visit is never enough: eggs are protected and hatch roughly one to two weeks later. The follow-up visit exists to catch that generation. A single treatment removes the adults and leaves the next wave.

What the schedule looks like:

Stage	What happens
Visit 1	Full treatment of frame, mattress, surrounding furniture and room
1–2 weeks	Eggs hatch; sightings may briefly continue — this is expected
Visit 2	Treats the newly hatched generation
Visit 3 if needed	Confirms clearance in heavier cases

Seeing one after the first visit is normal and does not mean the treatment failed. Tell us rather than spraying it yourself.

Your preparation shortens the whole programme: strip and hot-wash bedding, declutter around the bed, and give access to the frame.
