A Story from the Field: The Nursery That Was Ready Before the Water Came

Praewa is thirty years old and seven months pregnant with her first child. She lives with her husband, Ton, in a three-storey townhouse in the Chong Nonsi area of Yan Nawa district, Bangkok. A few weeks before the floods, the couple finished turning a small ground-floor room next to the living room into a nursery. It had a white wooden cot, a chest of drawers filled with tiny baby clothes that Praewa had already washed and folded, a stack of cloth nappies and swaddles, and a soft pastel rubber play mat she had chosen herself, piece by piece.

When the 2026 floods reached their street, water came into the ground floor almost to knee height and stayed for several days. The couple carried what they could up the stairs, but the cot and the chest of drawers were too heavy to move quickly. Praewa went to stay with her own mother in Bang Na, while Ton went back to the house whenever the water allowed.

After the water drained away, Ton sent his wife photographs. A tide line ran around the nursery walls, and grey-black mold spots had started to appear beneath it. The legs of the cot had swollen. The bottom drawer, where the baby clothes were kept, gave off a strong damp smell the moment it was opened, and mud had settled into the grooves of the rubber play mat. Praewa sat looking at the pictures and cried. Her due date was only two months away, and the room she had imagined bringing her newborn home to now looked and smelled like somewhere she would not want to leave a pair of shoes, let alone a baby.

Her first question was, "Should I go back and help clean?" More questions followed quickly. "Will the disinfectant affect the baby? Is ozone dangerous? Do I have to throw away all the baby clothes I washed? When can I actually go home?" This article answers those questions one by one, for families in Yan Nawa, Bang Kho Laem, Sathorn and nearby districts who have a mother-to-be in the household.

Why a Post-Flood Home Needs Extra Care When Someone Is Pregnant

Pregnancy brings many changes to the body. Many women tire more easily, become much more sensitive to smells, feel congested, or find it harder to take a full breath in the final trimester. A home with mold and a musty odor can therefore feel far more uncomfortable than it would to anyone else in the family. The most common concerns in a home that has just come out of a flood are these.

• Germs carried by floodwater. Urban floodwater is often contaminated with wastewater and sewage. Mud left behind can carry germs linked to diarrhea, skin infections and leptospirosis, the illness Thai people call "rat urine fever". Pregnant women should be cautious and should see a doctor promptly if they develop a fever after any contact with floodwater.
• Mold spores. Mold growing on walls and on wet fabric releases spores into the air. These can trigger allergies, a blocked nose, coughing, and asthma symptoms in people who already have a tendency toward them.
• Harsh cleaning chemicals. Using strong bleach, or mixing several cleaning products together in a closed room, produces fumes that irritate the airways. That is not something a mother-to-be should be breathing.
• Heavy work and slippery floors. Lifting wet furniture, bending to scrub floors and walking on surfaces still slick with mud are physical risks that families often underestimate. A fall during late pregnancy is a serious matter.

Note: This article is general information about cleaning homes. It is not medical advice. If a mother-to-be has a fever, abdominal pain, a rash or any unusual symptom, she should contact her doctor or the hospital where she receives antenatal care straight away.

Answering the Questions Mothers-to-Be Ask Most

Should the expectant mother do any of the cleaning herself?
The safest answer is no. Shovelling mud, carrying soaked belongings and scrubbing mold should be done by other family members or a professional team, and anyone doing that work should wear rubber gloves, rubber boots and a mask. The mother-to-be can still play an important role: planning, listing which items she wants to keep, and coordinating by phone from somewhere comfortable.

Will the disinfectant used for fogging affect her?
She should not be in the house while fogging takes place. She should return only after surfaces are dry and ventilation has been completed for the full time the team recommends. If she has specific concerns, she should ask her obstetrician, and she can request product information from the team to show the doctor.

Is ozone dangerous?
Ozone is a gas that is only ever used in empty spaces. During treatment there must be no people, pets or plants in the area. Afterwards, the space is ventilated until the recommended time has passed. When the procedure is followed properly, the expectant mother is never exposed to ozone during the work.

Do the washed baby clothes have to be thrown away?
If they were submerged in floodwater, consider discarding them, especially any fabric with visible mold. If they were not submerged but smell musty, most can be rewashed in hot water as the care label allows and dried thoroughly in strong sunlight. The drawers they were stored in must be cleaned and disinfected before anything goes back inside.

Can the wooden cot and the rubber play mat be saved?
A solid-wood cot that has not swollen or rotted badly can usually be washed, disinfected and dried. Plywood or MDF that has swollen should be replaced. A rubber mat can be cleaned if water has not seeped inside and it has not cracked. A baby mattress that was under floodwater should be discarded.

When can she go home?
When the mud and damaged items are out, the house has been disinfected and ozone-treated, ventilation is complete, the walls are visibly drying, there is no musty smell, and the ground-floor wiring has been checked. It is also worth mentioning the plan at her next antenatal appointment.

Why DIY Methods Often Fall Short in a Nursery

• Wiping mold with a cloth and cleaner. This removes what you can see on the surface, but spores in the gaps along the skirting, behind the chest of drawers and under the cot stay put and grow back while humidity remains high.
• Air-freshener sprays or bowls of charcoal. These do very little for odors that have soaked into walls and furniture, and strong fragrances can make an expectant mother feel nauseous.
• Repainting the nursery quickly. If the wall is still damp, mold will return under the paint, and the smell of fresh paint is something a mother close to her due date may prefer to avoid.
• Closing the room and running the air conditioner. Air conditioning removes some moisture, but if the ground-floor unit was splashed by floodwater or has pulled in spores, it becomes a machine that spreads musty air every time it is switched on.
• Putting everything back too soon. Returning freshly washed baby clothes to a room that still smells damp means they quickly pick up the odor again, and all that washing has to be repeated.

The Hidden Costs for an Expecting Family

Stress at the worst possible time. The last trimester is when many parents are finishing their preparations, attending more frequent check-ups and trying to rest. A flooded nursery throws all of that into confusion. Worry and broken sleep are hard on anyone, and harder still when the body is already working for two.

Time pressure. Unlike most home repairs, this one comes with a fixed deadline. The baby will arrive whether the room is ready or not. Families often feel they must rush, and rushing is exactly what leads to painting over damp walls or putting clothes back into a drawer that still smells.

Money spent twice. Baby furniture, mattresses, clothes and nappies are not cheap. Throwing away items that could have been saved is a waste, but keeping items that should have been discarded can mean buying them again later when mold reappears. Getting the sorting right the first time saves money.

Strain on the partner. In many families, the partner ends up doing everything alone: commuting to work, travelling back and forth to wherever the expectant mother is staying, and spending evenings and weekends scrubbing a house that never seems to stop smelling. Clear help and a clear plan take a great deal of weight off their shoulders.

The Solution: Disinfection Fogging and Ozone Treatment from World Health Disinfection

1. Disinfection fogging service with CHEMGENE HLD4H. The disinfectant is applied as a fine ultra-low-volume (ULV) mist that drifts into corners, along skirting boards, under the cot, behind the chest of drawers and into the ground-floor bathroom. It helps reduce bacteria, viruses and mold on surfaces that were in contact with floodwater.

2. Ozone treatment service. Ozone gas spreads throughout a closed room, breaks down musty odor molecules through oxidation, and helps deal with mold spores in the air. It suits a nursery especially well, because the goal is a clean, neutral smell rather than a perfumed one.

The Recommended Sequence for a Home with a Mother-to-Be

1. The expectant mother stays elsewhere first, for the whole period of clean-up, fogging, ozone treatment and ventilation.
2. Site survey. The team checks the flood line, mold spots and wall moisture, and advises which furniture can be kept and which should be replaced.
3. Clean-up and sorting. Family members or the team remove mud, any flooded baby mattress and soaked cardboard boxes. Baby clothes are separated for washing and sun-drying.
4. Disinfection fogging. CHEMGENE HLD4H is applied across the ground floor, the nursery, the kitchen, the bathroom and all high-touch points.
5. Ozone treatment. The nursery and other ground-floor rooms are sealed one zone at a time, and the generator runs according to room size and odor level.
6. Ventilation. Doors and windows are opened so air can flow through for the full time the team specifies.
7. Re-check, then set up the nursery again. Once the walls are dry and the smell is gone, washed clothes and baby items go back in. The mother-to-be returns last.

Looking After the Home in the Two Months Before the Birth

After disinfection and ozone treatment, the home gets a clean fresh start. But walls that sat in water keep releasing moisture for some time. These small habits help keep the nursery clean right up to the day the baby arrives.

• Open the windows on sunny days. Let air move through the nursery every day, and close up when heavy rain comes.
• Check the corners weekly. Look especially behind furniture and along skirting boards. If a small mold spot appears, ask another family member to wipe it away at once.
• Clean the ground-floor air-conditioner filters, or call a technician if the unit was splashed or smells musty when switched on.
• Store baby clothes in closed boxes. After washing and drying them completely, keep them in lidded plastic boxes until they are needed.
• Buy new items gradually. There is no need to bring everything home at once. Give the room time to air and dry fully first.
• Keep a note of any symptoms. If the mother-to-be develops congestion, a cough or a rash she has not had before after moving back, mention it to her obstetrician at the next appointment, or sooner if it is severe.

A Simple Plan Partners and Relatives Can Follow

Many partners ask us what they should actually do first. Every home is different, but this practical outline works well for most families with an expectant mother.

1. Day one: document and decide. Take photos of every room, especially the nursery, before moving anything. Share them with the mother-to-be so she can decide which sentimental items matter most. Call the team to book a survey.
2. Days two and three: clear out. Wearing gloves, boots and a mask, remove mud, flooded mattresses, cardboard and anything soft that sat in the water. Bag the baby clothes separately for washing.
3. Day four: wash and dry. Wash baby clothes, swaddles and cloth nappies that were not submerged, and dry them in strong sun. Clean the cot and play mat if they are worth keeping.
4. Service day: fogging and ozone. The team disinfects and treats the home. Nobody stays inside during ozone treatment, and the ventilation time is followed in full.
5. The following days: dry and watch. Keep windows open in good weather, check corners for new spots, and only then begin setting up the nursery again.
6. Homecoming. When the house smells clean and the walls are visibly dry, the mother-to-be comes home last, to a room that is ready for the baby.

Before and After Disinfection and Ozone Treatment

Customer Voice (Example Scenario)

"My wife wanted to come back and help, so I called the team first. They suggested she stay at her mother's for now, and told me the solid-wood cot could be saved but the baby mattress had to go. After the fogging and ozone, and once the ventilation was finished, the nursery had no musty smell at all. My wife came home and set up the room again in time for the birth."

Frequently Asked Questions

Q: How long does the mother-to-be need to stay away?
A: It depends on the size of the home and the amount of clean-up. The team tells you the start time, the ozone treatment time and the ventilation time in advance so you can plan the return.

Q: Can you treat only the nursery?
A: Yes, but if the whole ground floor was flooded we recommend treating the whole floor, because odors and spores from neighbouring rooms will drift back into the nursery.

Q: Will the nursery smell of chemicals after ozone treatment?
A: Once ventilation is complete, the ozone smell fades and the room is left with a clean, neutral smell.

Q: Should we repaint the nursery?
A: If repainting is necessary, wait until the wall is completely dry, and finish well before the mother-to-be returns so the paint smell has time to fade. Ask your painter about low-odor paints.

Q: Can we use a disinfectant spray ourselves afterwards?
A: Yes. The CHEMGENE HLD4H 750 ml spray is convenient for wiping high-touch points. It is best if another family member does the wiping, with a window open.

Q: Will ozone damage baby bottles, teats or the rubber play mat?
A: High ozone concentrations can affect rubber and some soft plastics over time. That is why we ask you to remove bottles, teats, pacifiers and breast-pump parts from the room before treatment, and why the team controls the dose to suit the space. A rubber play mat can be cleaned and set aside outside the treated room, then brought back after ventilation.

Q: Which areas do you serve?
A: Yan Nawa, Bang Kho Laem, Sathorn, Khlong Toei, Bang Na and neighbouring areas of Bangkok. Message LINE @whd268 with a few photos of the affected rooms to check availability and get initial advice.

Q: Does this article replace medical advice?
A: No. For any unusual symptom or health question, please consult the doctor managing the pregnancy.
