A riverside temple kitchen in Chaiyo and Uncle Sathian's question

(A typical scenario based on common real-world situations; an illustrative example, not a review from any specific customer.)

Uncle Sathian looks after the finances of a small temple on the Chao Phraya in Chaiyo district. Every high-water year, the temple yard becomes a car park for villagers moving their vehicles to safety, and the temple kitchen turns into a charity kitchen, cooking rice porridge and side dishes for families whose homes are flooded. This year is no different. The water has crept up until the riverside part of the yard is under water, and the ground floor of the kitchen has water seeping up through the tile joints.

Uncle Sathian and the volunteer cooks moved the stoves, pots and rice sacks up into the hall and kept cooking on higher ground. What worries him is what comes next: a kitchen soaked for days, shared toilets where septic water flowed back, and a hall where dozens of people have been sleeping side by side. In earlier years everyone simply washed, scrubbed and carried on. But last year several villagers had diarrhoea after eating at a merit-making event held after the flood, and fever passed from child to child across the village.

"Not like last time," he told his son, who works in Bangkok. His son looked up disinfection spraying services and suggested contacting one now, while the water is still rising, to learn what to prepare, so that once it recedes they can clean and spray in the right order instead of starting from scratch on the day everyone is most exhausted.

Flooded areas in Ang Thong, according to the DDPM report of 2 October 2026

According to the DDPM report of 2 October 2026, five districts of Ang Thong were affected, a total of 2,009 households, and the water level was rising. This trend was reported for the province as a whole. Figures and conditions change daily, so follow the latest announcements from Ang Thong province and DDPM closely.

• Pa Mok: listed as affected; status: water rising (province-wide trend in the report).
• Chaiyo: listed as affected; status: water rising (province-wide trend in the report).
• Wiset Chai Chan: listed as affected; status: water rising (province-wide trend in the report).
• Mueang Ang Thong: listed as affected; status: water rising (province-wide trend in the report).
• Samko: listed as affected; status: water rising (province-wide trend in the report).

Nationally, DDPM reported on 2 October 2026 that 31 provinces plus Bangkok were flooded, with 1,245,581 households and 3,535,206 people affected, caused by heavy to very heavy rain plus runoff from the north. Ang Thong sits on the central plains, with the Chao Phraya running through the province and the Noi River on its western side, so it regularly receives water from upstream in high-water years.

Note: the report does not break households down by district or name the temples, schools or markets affected. If water entered, seeped into or backed up through drains in your building at any depth, treat touched surfaces as contaminated until cleaned and disinfected.

The water in Ang Thong is still rising: what to do before spraying day

Spraying while the water is still in a building achieves little, because the water keeps bringing new germs and disinfectant cannot work on submerged or mud-coated surfaces. But this rising phase is exactly when caretakers of shared spaces in Ang Thong can prepare best.

1. Safety first: switch off power to zones the water will reach, never wade near submerged cables or sockets, and watch for snakes and other animals seeking shelter indoors.
2. Lift things up: rice, dry food, schoolbooks, official papers, monks' robes, mats and pillows. The more you lift, the less you throw away to mold later.
3. Take photos before and during the flood: for official claims, and to see which rooms stayed under water longest, because those need the most thorough cleaning and disinfection.
4. List the areas to disinfect: kitchens, shared toilets, halls, ground-floor classrooms, market stalls and storerooms, with rough sizes.
5. Contact a spraying team in advance: share your district, type of space and size, so the visit can be scheduled right after cleaning.
6. Prepare cleaning gear: boots, rubber gloves, masks, brooms, shovels, detergent and large rubbish bags, ready the moment the water drops.

With this done, the day the water recedes becomes a day everyone knows the order: remove mud, wash, dry, then spray, which sharply cuts the time mold and bacteria have to grow.

Shared spaces in Ang Thong to disinfect first after the water recedes

Ang Thong is a small province, but community life is tightly bound to its temples, markets and rivers. The places many families share matter most when the water goes down.

• Temples and sermon halls: Ang Thong has several well-known temples, such as Wat Pa Mok Worawihan in Pa Mok, Wat Chaiyo Worawihan in Chaiyo and Wat Muang in Wiset Chai Chan, plus many village temples. Temples often act as shelters, charity kitchens and venues for merit-making after a flood, with many elderly visitors.
• Old markets and fresh markets: the old market quarter in Wiset Chai Chan and markets in Mueang Ang Thong have wooden shophouses, food shops, dessert stalls and fresh stalls side by side. When water gets under wooden floors, moisture lingers and mold grows easily.
• Schools and childcare centres: in every district, especially rice-farming areas like Samko and Wiset Chai Chan, childcare centres are often single-storey, so water easily reaches nap rooms and play areas.
• Craft communities and shops in Pa Mok: Pa Mok is known for crafts such as drum-making and traditional dolls. Small workshops and souvenir shops hold wood, leather, fabric and clay, all sensitive to damp and mold.
• Rice mills, warehouses and farm cooperatives: where farmers meet. Damp paddy and rats escaping the water combine mold and leptospirosis risk.
• District offices, municipalities, subdistrict administrations and health-promoting hospitals: after a flood, residents queue for relief and health services, making waiting areas and counters key shared touch points.

The many germs after the Ang Thong floods: bacteria, viruses and fungi

Water flooding Ang Thong passes through rice fields, animal pens, septic tanks, drains and villages, picking up many kinds of germs. WHO and CDC advise treating everything touched by flood water as contaminated, and cleaning and disinfecting it before use.

Bacteria

E. coli and faecal bacteria: when home and temple septic tanks and toilets go under, sewage spreads with the water and settles on kitchen floors, under sinks, in tile joints and on toilet floors, causing diarrhoea, stomach cramps, nausea and vomiting.

Salmonella: linked to food poisoning and a key risk for temple charity kitchens, market food shops and school canteens, because it can survive on chopping boards, pots, trays and fridges the water reached, then pass into food served to many people.

Leptospira (leptospirosis): Ang Thong is rice country with plenty of rats. During floods they move up into halls, storerooms and rice stores. The bacteria in their urine live in standing water and wet soil and enter through cuts or the eyes and mouth. Anyone who waded and then develops high fever, headache and severe calf pain must see a doctor immediately and mention the flood exposure. Spraying lowers risk on indoor surfaces but does not replace treatment.

Viruses

Norovirus and rotavirus: cause diarrhoea and vomiting, spread hand to mouth and survive long on surfaces. In temples where people sleep together, or charity kitchens where people queue for food, they spread very quickly.

Hand, foot and mouth disease: common in young children. Childcare centres reopening after the flood should disinfect toys, nap mats and floors before children return.

RSV and influenza: respiratory viruses that spread in the rainy season. People sharing temple halls or temporary shelters pass them on easily, and young children and older adults face more severe illness.

Mold and musty odour

Mold is the biggest problem for stilt houses, old wooden shophouses and temple halls in Ang Thong, because wood absorbs water and dries slowly. WHO and CDC advise cleaning and drying within 24 to 48 hours to limit mold, but after water has stood for days, as Ang Thong is now experiencing, mold starts almost as soon as it recedes. Spores trigger allergies, sneezing, blocked noses, eye irritation and asthma attacks.

Musty odour signals remaining moisture, mold or bacteria. Spraying reduces odour-causing germs on surfaces; for smells in the air of closed rooms, such as robe stores or monks' quarters, the residential ozone disinfection service can be added as an extra step.

Who is most at risk

Older temple-goers, young children in childcare centres, pregnant women, people with chronic illness or weak immunity, and people with allergies or asthma need protecting first. Spaces they use often should be first in line for disinfection.

What happens if temples, markets and schools in Ang Thong skip disinfection

Health: a merit-making event for hundreds of people, cooked in a kitchen that still carries germs, can start a wave of diarrhoea across a village.

Income: old-market shops and Pa Mok craft stores depend on regulars and visitors who come to pay respects at the temples. A musty shop or mold on goods sends customers elsewhere.

Time: without full cleaning and disinfection, mold returns within weeks, meaning more scrubbing, repainting and throwing things out.

Trust: parents want to know classrooms are safe, and temple supporters want to know the food is safe. Systematic disinfection lets you answer with confidence.

Family: in communities where working-age adults live elsewhere, grandparents often care for small grandchildren. If one falls ill, the whole burden lands on the other.

Why the usual wash-down is not enough for Ang Thong temple halls and wooden shophouses

Wood soaks deep: floors, walls and posts in stilt houses and old shophouses absorb water. Hosing the surface does not reach germs in grain and joints.

Bleach used wrongly: unmeasured, mixed with toilet cleaner into irritating fumes, or used on surfaces still coated with mud, it loses much of its effect.

Waiting to dry: after days of flooding, riverside air stays humid, so natural drying is too slow to stop mold.

Painting over or covering with new cloth: looks tidy fast, but mold beneath returns.

Incense and air fresheners: mask the smell, not the cause.

Wiping only what you see: one temple hall has posts, railings, altar tables, a preaching seat and dozens of plastic chairs. Hand-wiping misses spots easily.

What closes the gap is an evidence-backed disinfectant applied evenly to every surface.

How WHD disinfection spraying works in flooded areas of Ang Thong

According to World Health Disinfection (WHD) service information, trained technicians spray and/or ULV-fog (Ultra Low Volume), turning disinfectant into a very fine mist that floats and settles evenly on floors, lower walls, wooden posts, under tables and stalls, and in shared-toilet corners that hand-wiping misses.

The disinfectant is CHEMGENE HLD4H, a medical-grade disinfectant from the UK containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. According to the service information it covers viruses, bacteria and fungi; the service page lists organisms including COVID-19, RSV, H1N1, H5N1 and hand, foot and mouth virus, states 99.99% effectiveness, and lists approvals or endorsements from the Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019.

How the mist reaches surfaces after cleaning

Disinfectant must touch the germs to work. If mud remains, it lands on the mud instead. The right order is: remove mud, wash with water and detergent, dry as much as possible, then spray. The ULV mist settles evenly on cleaned surfaces, including wood grain, post edges and under shelves, so the disinfectant can act on germs left after washing.

The service process

1. Book: call 065-556-6294 or LINE @whd268 with your district, type of space, size and photos. You can contact the team to plan ahead while the water is still rising.
2. Prepare: remove mud, clean, store food, dishes and personal items, and move people, pets and plants out of the spray zone.
3. Technicians spray: wearing protective equipment, one zone at a time.
4. Wait about 30 minutes: per the service information, and re-enter at the time the technicians give.
5. Return to normal use: ventilate and use the space.

Service in Ang Thong

WHD is based in Bang Khae, Bangkok, with no branch in Ang Thong. Service in Pa Mok, Chaiyo, Wiset Chai Chan, Mueang or Samko is planned by phone or LINE, with dates and travel confirmed case by case; same-day arrival cannot be guaranteed. Getting in touch while the water is still rising helps secure a slot that matches the day your space is ready.

Safety notes

Everyone should leave the zone during spraying and return only at the time the technicians give. Spraying comes after mud removal and washing; it does not replace structural repair, replacing damaged materials or medical care. Anyone who feels ill should see a doctor.

Promotion, per the service information: a free CHEMGENE spray bottle and WELLGIENIC wet tissues with the service, and a tax invoice on request, convenient for temples, schools and local agencies.

10 reasons Ang Thong temples, markets and schools should plan post-flood spraying

1. Plan while the water is rising, then clean and spray in order as soon as it drops, cutting the time mold has to grow.
2. Bacteria, viruses and fungi in one round with a medical-grade disinfection service.
3. Mist reaches wood grain, posts and under altar tables that are hard to wipe by hand.
4. Safer temple kitchens before cooking for crowds again.
5. Childcare centres and schools reopen with more confidence about hand, foot and mouth disease and RSV.
6. Old-market shops and Pa Mok craft stores lower the risk of mold in sales floors and stockrooms.
7. About 30 minutes of waiting, per the service information, then normal use.
8. A disinfectant with EN 14476 and agency approvals listed on the service page, so you can check.
9. Tax invoice available, plus a CHEMGENE spray bottle and WELLGIENIC wet tissues for ongoing care of touch points.
10. A team that serves hospitals, schools and large buildings, per the customer list on the service page. See more on the WHD disinfection service page.

Before and after: what Ang Thong temples and markets typically see

Note: results depend on removing mud, washing and drying first. Rotten wood or deeply moldy materials such as mattresses or gypsum boards may need replacing.

Example case: a pharmacy and a grocery in wooden shophouses, Wiset Chai Chan old market

(An illustrative example case, not a verified review.)

Khun Nid runs a grocery in a two-storey wooden shophouse handed down from her grandmother, in the old market quarter of Wiset Chai Chan. Next door is a neighbour's pharmacy, and the two shops share the front walkway and a back toilet. As the water rose, Khun Nid moved her stock upstairs, but the ground-floor boards and boxes stacked near the floor still got wet.

While the water was still up, she and the pharmacy owner agreed to contact a spraying team early. They sent photos and sizes of both shophouses on LINE. The team explained the order: remove mud and damaged boxes, wash the boards with detergent, open the windows until the floor is as dry as possible, then book the spraying date.

Once the water receded and cleaning was done, the team confirmed a visit. Technicians sprayed both units, the front walkway and the shared toilet. Everyone waited outside and came back at the time given. Khun Nid kept the free CHEMGENE bottle to spray the counter and door handles every morning in the first week of reopening.

What she told her neighbours was simple: planning while the water was still rising meant she did not have to decide everything on the most exhausting day, and the shop reopened with the confidence of customers who walk through the market every day.

Recovery checklist for shared spaces in Ang Thong

While the water is rising

• Cut power to zones the water will reach; never wade near cables.
• Lift food, papers, fabric, mats and pillows to higher places.
• Photograph rooms and note which stayed under water longest.
• Contact a spraying team early with your district and type of space.

After the water drops, before spraying

• Have an electrician check before switching on.
• Wear boots, rubber gloves and a mask, and cover cuts before shovelling mud.
• Remove mud and throw out ruined, soaked materials.
• Wash floors, lower walls, posts and furniture with detergent, then ventilate until dry.
• Throw away all food and ingredients that touched flood water.
• Tell technicians in advance about Buddha images, scripture cabinets or objects needing special care.

On the day and afterwards

• Move people, pets and plants out of the spray zone.
• Wait for the time the technicians give (about 30 minutes per the service information), then ventilate.
• Rinse food containers with clean water before use.
• Spray shared touch points with CHEMGENE regularly in the first week.
• If new mold appears, check for damp spots or leaks.
• Anyone with fever, diarrhoea or calf pain after wading should see a doctor at once.

FAQ: post-flood disinfection in Ang Thong

The water is still rising. Can we spray now?

Not yet. Spray after the water recedes, the mud is removed and surfaces are washed. You can contact the team now to plan.

Does WHD have a branch in Ang Thong?

No. WHD is in Bang Khae, Bangkok. Service in Ang Thong is planned by phone on 065-556-6294 or LINE @whd268, with dates and travel confirmed case by case; same-day arrival is not guaranteed.

Do we have to leave during spraying?

Yes, and return at the time the technicians give; the service information says to wait about 30 minutes.

Can a temple hall or monks' quarters be sprayed?

Yes. Tell the technicians in advance about Buddha images and important objects so they can plan and protect them.

Our wooden house or shophouse still smells musty. What else can we do?

After spraying, if the air in a closed room still smells, consider ozone treatment as an extra step, and check for wood that is still damp.

After spraying, do we still need a doctor?

Yes, if anyone is ill. Spraying reduces germs on indoor surfaces, but fever, diarrhoea or calf pain after wading needs a doctor.
