Bed Bugs: How to Confirm Them and the Two-Visit Treatment | Al Asfour Al Zahabi

Learn the signs that confirm bed bugs in mattress seams, bed frames and sofas, and why bites alone are not proof. We also explain why household sprays fail, how a professional two-visit treatment works and what to do with your clothes and bedding.

You wake up with itching and red marks on your arms or neck, and bed bugs immediately come to mind. But the right answer does not come from what the bite looks like; it comes from signs you can see with your own eyes on the mattress, the bed frame and the sofa. In this guide you will learn how to confirm bed bugs in your home, why household sprays usually fail, how a professional two-visit treatment works, what to do with your clothes and bedding, and when to expect the problem to be over.

How to recognise bed bugs and tell them apart from other insects

The bed bug is a small, flat, wingless insect. It does not fly or jump. It feeds on human blood, mostly at night, and then goes back to hide in cracks close to where you sleep. An adult is roughly the size of an apple seed (5 to 7 millimetres), reddish-brown, and its body becomes swollen and redder after feeding.

Nymphs, the young, are smaller and paler. Before they feed they look almost translucent or pale yellow, so many people miss them during a quick check. The eggs are pearly white, about the size of a pinhead, and are glued in small clusters inside seams and cracks, which makes them hard to remove with ordinary wiping.

Insects people confuse with bed bugs

Fleas: they jump strongly, their bodies are flattened from side to side, and they are usually linked to cats, dogs or stray cats around the home. Their bites tend to concentrate around the ankles and lower legs.
Young cockroaches: much faster, with long antennae, and they live near the kitchen, bathroom and drains, not inside mattress seams.
Carpet beetles: small, round and mottled, with hairy larvae. They eat wool and fabrics but do not bite people.
Mosquitoes: their bites are scattered over exposed skin, and you usually hear them buzzing or see them on the wall.

If you catch a suspicious insect, stick it on clear tape or keep it in a small sealed bag, or take a sharp close-up photo. This saves the technician a lot of time and settles the identification from the start.

Why bites alone do not prove an infestation

Bed bug bites usually appear as slightly raised red spots, sometimes in a line or a cluster of three or four close together on the arms, shoulders or neck. But this pattern is not unique to bed bugs. Mosquito and flea bites, a reaction to a new washing powder, and the heat rash that is common in the UAE summer can all look very similar.

More importantly, many people show no reaction at all when bitten, and in others the itching can be delayed by a day or several days. So two people can sleep in the same room, one of them itches, and the other assumes there is no problem. The practical rule: do not start treatment based on bites alone, and do not rule out an infestation just because nobody is complaining. Look for physical evidence. If the itching is severe or the skin becomes infected from scratching, see a doctor or pharmacist.

Where to look and how to inspect, step by step

A good inspection needs simple tools: a strong torch (your phone torch will do), an old plastic card to run along seams, a white tissue, gloves and sticky tape. The best time to check is early morning, or at night an hour or two after the lights go off, when bed bugs are most active.

Remove the sheets and pillowcases slowly and put them straight into a sealed plastic bag instead of dropping them on the floor.
Check the mattress seams, piped edges, all four corners and the labels, and run the card along each seam to push out anything inside.
Lift the mattress and inspect the base from underneath, especially the fabric stapled under the bed base.
Inspect the bed frame: the joints, screw holes and gaps behind the headboard are favourite spots, particularly upholstered headboards or those fixed to the wall.
Move to the bedside tables: pull out the drawers and check their corners and the inside of the frame.
Check sofas and upholstered chairs: under the cushions, along the seams and under the fabric at the bottom, especially if someone sleeps on the sofa or sits there for long evenings.
In moderate and heavy infestations, also check carpet edges, skirting boards, curtain folds, behind picture frames and the cover plates of sockets and switches near the bed.

Signs that confirm bed bugs

Small black dots that look like marker-pen spots. These are bed bug droppings. If you wipe them with a damp tissue they smear reddish-brown, which is a simple and useful test.
Tiny blood spots on sheets or pillowcases, usually from a fed bug being crushed during sleep.
Empty shed skins in a light honey colour, because nymphs moult five times before becoming adults.
White eggs and empty egg shells inside seams and cracks.
Live bugs of various sizes, the clearest evidence of all.
A sweet, musty smell in the room, which usually appears only in heavy infestations.

You can also place special interceptor cups under the bed legs. They catch bed bugs climbing up or down and help you monitor before and after treatment. Move the bed a few centimetres away from the wall and do not let the sheets touch the floor, so the legs are the only way up.

Why bed bugs spread in UAE homes

Having bed bugs does not mean your home is dirty. They travel with people and their belongings, and all they need is a hiding place near a sleeping person. In the UAE, several factors make it easier for them to move around:

Frequent travel through Dubai, Abu Dhabi and Sharjah airports, and stays in hotels, serviced apartments and short-term rentals.
Shared accommodation and bed-space rentals, where beds are close together and people share belongings.
Trade in second-hand furniture and mattresses on selling platforms, and frequent moves between apartments when leases are renewed.
Large residential towers, where bed bugs can move between neighbouring flats through corridors, electrical conduits and gaps around pipes.
Air conditioning that keeps indoor temperatures steady all year, which suits breeding with no seasonal break. Adult bed bugs can also survive for months without feeding.

If you have recently come back from a trip or bought used furniture, read our guide to bed bugs after travel and second-hand furniture to learn how to stop them getting in at all.

Why household sprays and quick fixes fail

Most people start with a can of spray from the supermarket, then notice the bugs disappear for a few days and come back. That is expected, for clear reasons:

Resistance: many bed bug populations have become resistant to common household insecticides, so they are barely affected.
Eggs survive: most sprays do not kill eggs, so they hatch a few days later and a new cycle begins.
Sprays only reach what is visible: bed bugs hide deep in cracks in wood and fabric that a surface spray does not reach.
Scattering: some insecticides have a repellent effect that pushes bugs into other rooms or into the neighbours' flat, so the problem grows.
Household fogger "bug bombs": they do not penetrate the cracks where bed bugs hide, they can scatter them, and some are a fire risk near gas cookers.

Other mistakes make things worse. Moving to sleep on the sofa or in another room means the bugs follow you and you end up with two infested rooms. Throwing out the mattress and dragging it through the corridor and lift without wrapping it spreads bugs through the building, and a new mattress becomes infested within weeks because the room was never treated. Never use agricultural pesticides or mix chemicals at home, and do not try alcohol or kerosene on mattresses. They are dangerous, flammable and do not solve the problem.

How the professional two-visit treatment works

Bed bug treatment is an organised process, not a single spray. A specialist technician combines a careful inspection with more than one treatment method and comes back at the right time.

First visit: inspection, then treatment

The visit starts with an inspection of the bedrooms, the majlis and anywhere someone sleeps, to measure the size of the infestation and see whether it has reached other rooms. The technician then chooses the right method for each area:

Targeted residual spraying with insecticides licensed for bed bugs on the bed frame and its joints, cracks, skirting boards and the underside of furniture, so the product stays active on surfaces for weeks.
Specialist dusts applied in precise amounts inside voids, deep cracks and behind skirting boards, places a spray cannot reach.
High-temperature steam where appropriate, such as mattress seams, sofas and fabrics that should not be sprayed heavily. Steam kills bugs and eggs on contact but leaves no residual effect, so it is used alongside the other methods, not instead of them.
Dismantling the bed when needed to treat joints and internal holes, along with advice on zipped, sealed mattress encasements that trap anything left inside the mattress.

Second visit after 10 to 14 days

Eggs present at the first visit usually hatch within roughly a week to ten days at air-conditioned indoor temperatures. The timing of the second visit is deliberate: it comes after most eggs have hatched and before the new nymphs grow up and lay eggs of their own, which breaks the breeding cycle. On this visit the technician inspects again, treats any spots showing new signs and checks that neighbouring rooms are clear. In heavy infestations, or where there is a lot of cluttered furniture, a third visit may be needed.

When can you go back into the room?

In most cases you can return after a few hours, once the spray is completely dry and the room has been well ventilated. Always follow the technician's instructions, because the time varies with the product used. Keep children and pets out of treated rooms until surfaces are dry, and cover fish tanks and switch off their pumps if they are nearby. Our guide to keeping children and pets safe during pest control has more detail.

When will the bed bugs be completely gone?

After the first visit, most people notice a clear drop within days. Do not worry if you see the odd bug or bite in the first two weeks: newly hatched nymphs come out, walk over treated surfaces and then die. In typical cases the problem is over within three to six weeks of starting treatment, that is, after the second visit. Keep checking the interceptors under the bed legs for a few weeks afterwards; if they stay empty, that is a good sign.

The timeline depends on the size of the infestation, how much clutter there is, whether the neighbours are affected and how closely you follow the washing and preparation instructions. Cost usually starts from 150 AED for a small apartment and varies with the area, the level of infestation and the number of rooms.

How to prepare before the visit and what to do afterwards

The right preparation improves the chances of success from the first visit. Before the technician arrives:

Do not move furniture, mattresses or belongings from the infested room into other rooms.
Collect sheets, covers and clothes near the bed in sealed bags and wash them as explained in the next section.
Clear the space under the bed and reduce clutter around it, because clutter gives bed bugs extra hiding places.
Empty bedside drawers into sealed bags so the technician can treat them.
Vacuum around the bed and sofa, then empty the vacuum container into a sealed bag and take it out of the flat immediately.
Do not spray any household insecticide before the visit, as it can scatter the bugs and make them harder to locate.
Tell the technician if there is a baby, a pregnant woman, or anyone with allergies or asthma in the home, and about any pets.

For a complete list, see our pest control visit preparation checklist. After the visit, do not wipe treated skirting boards and cracks with water and cleaning products until the second visit. Keep vacuuming floors and mattresses, and sleep in your own bed as usual: your presence is what draws the bugs out to cross the treated surfaces.

What to do with clothes, bedding and belongings

Heat is your strongest weapon at home. Bed bugs and their eggs cannot tolerate high temperatures, and the dryer matters more than the washing machine at this stage.

Items that can take a hot wash: wash at 60°C if the fabric allows, then tumble dry on high heat for at least 30 minutes.
Items that do not need washing: clean clothes, light curtains and fabric shoes only need 30 minutes in the dryer on high heat.
Delicate fabrics: put them in sealed bags and send them for dry cleaning, and tell the laundry they may contain insects.
Small items that cannot go in the dryer: such as some toys and bags can go in a sealed bag in the freezer at minus 18°C for several days (at least four days).
Books and electronics: do not put them in the dryer or freezer. Inspect them carefully with a torch and let the technician decide how to deal with them.

After drying, put clothes straight into new sealed bags and do not return them to the wardrobe until it has been treated and confirmed clear. If you use shared washing machines in your building, carry the clothes there in sealed bags and throw the bags away after unloading. As for the mattress itself, in most cases it does not need to be thrown away: it is treated and then fitted with a sealed encasement that stays on for about a year, because any bugs trapped inside die over time.

When do you need a pest control company?

We recommend contacting a licensed pest control company in any of the following situations:

You have found a live bug, eggs or shed skins, even in small numbers.
Signs are present in more than one room or on the sofa.
You live in a tower or shared building and suspect the neighbours are affected.
There are young children, elderly people or people with allergies at home, and you do not want to try chemicals yourself.
You have tried sprays and home remedies and the bugs came back weeks later.

The earlier treatment starts, the faster and cheaper it is. We offer bed bug control in Dubai and across the other emirates, with two visits covering inspection, treatment and follow-up.

Frequently asked questions

Can I have bed bugs at home without noticing bites?

Yes. Many people show no reaction to bites, so an infestation can go unnoticed for weeks until someone sees black dots or insects on the mattress.

Should I throw away the mattress and sofa?

In most cases, no. Professional treatment with sealed mattress encasements is enough. Throw a mattress away only if it is damaged or its fabric is badly torn, and in that case wrap it tightly before taking it out and slash the fabric so nobody picks it up.

Do bed bugs fly or travel on pets?

They do not fly or jump, and they do not live on pets the way fleas do. They move by crawling and travel in luggage, clothes and furniture.

Why am I still seeing bed bugs after the first visit?

This is normal in the first two weeks, because eggs hatch and the nymphs come out and die when they touch treated surfaces. That is why the second visit comes 10 to 14 days later. If the numbers rise instead of falling, tell the technician straight away.

Is it enough to treat only the infested bedroom?

The technician should inspect neighbouring rooms and seating areas, and if signs appear there, they are treated too. Treating one room while leaving another infested room untouched means the problem will come back.

Do bed bugs come back after treatment is finished?

They do not return on their own once the infestation is over, but they can be brought in again through travel, second-hand furniture or an infested neighbouring flat. Check your luggage after trips and inspect any used furniture before bringing it in.
