A Story from the Field: Khun Nok's Homestay Among the Orchard Canals

Khun Nok is thirty-eight. Several years ago she came home to take over her parents' fruit orchard in Ban Phaeo district, Samut Sakhon. She turned part of the orchard into an eco-homestay: six wooden and bamboo bungalows lined up along the orchard canals, with thatched nipa-palm roofs, an open pavilion over the water where guests eat together, rowing boats for exploring the canals, and activities such as fruit picking and making traditional Thai desserts. Most guests are families from Bangkok and international travelers who want a taste of orchard life.

During the October 2026 floods, water in the orchard canals rose over the earth banks and flowed into the three lowest bungalows, reaching somewhere between ankle and mid-shin height, and stayed for about ten days. The other three bungalows, which stand higher on stilts, stayed above the water, but the humidity from the water all around and the continuous rain left every one of them damp and stale.

When the water receded, Khun Nok found mud on the bamboo floors of the flooded bungalows and white mold forming around the bamboo joints. The lower parts of the wooden walls had black spots. Mattresses and pillows sitting on the wooden bed platforms had soaked up moisture and smelled musty. The bed sheets and towels in the linen room had small mold spots, and the seat cushions in the pavilion gave off a sour, stale odor. In a few weeks the year-end tourist season would begin, and several groups had already booked.

Khun Nok had two worries at once. First, she was afraid guests would find musty smells and mold and be disappointed. Second, her homestay is built on being natural. She did not want to use chemicals carelessly and harm the trees, the fish in the orchard canals, or the bees that pollinate the flowers in her garden.

This article is written for owners of homestays, eco-resorts, farm stays and garden accommodation in Ban Phaeo, Lak Sam, Lak Ha and the nearby orchard areas of Samut Sakhon and Ratchaburi who need to recover after the flood and be ready for guests, while keeping the natural character that guests come for.

Why Garden Accommodation Recovers More Slowly Than a Regular Hotel

• Natural materials absorb a lot of moisture. Bamboo, solid wood, rattan and thatched roofs soak up water easily, and they are exactly where mold likes to settle.
• Rooms are open to the breeze. Airy bungalows have many vents, so humidity from the canals comes in constantly, and those vents must be sealed before ozone treatment.
• Every room is surrounded by water and trees. The air is humid, so rooms dry more slowly than accommodation in town.
• There is a lot of fabric. Sheets, blankets, towels, mosquito nets and cushions stored in a damp room will all grow mold at the same time.
• The ecosystem matters. Spraying or pouring disinfectant into the canals, vegetable beds or flowering shrubs can affect fish, other aquatic life and beneficial insects.
• Reputation depends on reviews. Guests who book online tend to mention smell and cleanliness before almost anything else.

The good news is that the same open, natural design that makes these places vulnerable also helps them recover well once the work is done properly. Breezy bungalows dry quickly once mold and moisture sources have been dealt with, and guests who choose eco-stays are often very understanding when an owner explains clearly what has been done.

The Impacts Owners Need to Think Through

Health of guests and staff. Floodwater that has flowed through orchards and canals may carry organisms that cause diarrhea and skin infections, and areas with rats carry a risk of leptospirosis. Staff cleaning the canal banks should wear rubber boots and gloves. Mold spores in guest rooms can trigger allergies and coughing, especially in children and older guests. Anyone who develops a fever, muscle pain or an inflamed wound after wading through floodwater should see a doctor. This article is not medical advice.

High-season income. Many garden stays earn most of their income between the end of the year and the start of the next. Having to cancel bookings or give refunds because rooms are not ready affects the whole year.

Online reputation. Just a few reviews that mention a musty smell or mold in the rooms can make new guests hesitate for a long time.

The natural image. Guests who choose eco-accommodation expect the owner to care for the environment. Handling the post-flood clean-up carefully is a matter of health and of brand value at the same time.

Why the Usual Methods Fall Short

• Running fans to dry everything. It helps the surfaces, but moisture inside the bamboo joints, under the bed platforms and inside the mattresses stays put.
• Spraying bleach throughout the room. It stains bamboo and wood, the fumes are unpleasant, and rinse water running into the canal may harm aquatic life.
• Using air fresheners or reed diffusers to mask the smell. Guests still notice the mustiness, now mixed with perfume, which is often worse.
• Varnishing over damp wood. It seals the moisture inside, and mold returns under the coating.
• Washing the linen and putting it straight back in the same room. If the linen room is still damp and full of mold spores, freshly washed fabric will soon smell again.

Each of these is understandable when time is short, but each either ignores the moisture and spores that are actually causing the problem, or swaps one problem for another. A targeted plan avoids both traps.

The Solution: Targeted Indoor Disinfection, Ozone in Sealed Rooms, and Care for the Garden

The key to restoring garden accommodation is keeping disinfectant where it is actually needed. The World Health Disinfection (WHD) team provides disinfection fogging with CHEMGENE HLD4H through ULV equipment inside guest rooms, bathrooms, the linen room and surfaces guests touch, without spraying into the canals, vegetable beds or flowering shrubs. Then comes ozone treatment in rooms whose vents have been temporarily sealed, to help reduce mold spores and musty odors in natural materials and fabrics. Ozone breaks down back into oxygen once the room is ventilated, so it leaves no residue behind.

How the Work Is Done

1. Survey the whole property. We look at every bungalow, the pavilion, bathrooms, the linen room, the kitchen and walkways. We separate bungalows that were flooded directly from those that are damp from the air, and plan around your booking dates.
2. Advice on sorting belongings. Mattresses and pillows that sat in floodwater should be replaced. Sheets and towels should be washed in hot water and dried in strong sun. Cushions with a strong smell may need new fillings. A craftsman should assess thatched roofs that stayed wet for a long time.
3. Clear the mud and open the rooms to dry. Mud is washed off the bamboo floors and from under the bed platforms, swept up and disposed of separately, not rinsed straight into the canal.
4. Fog the interiors. We treat floors, walls, bed platforms, bamboo joints, bathrooms and the linen room, with the windows on the canal side closed during fogging.
5. Move plants and rubber items out. Potted plants used as room decoration, rubber decorations and sensitive electronics are moved out or covered.
6. Seal the vents and ozone-treat. Plastic sheeting temporarily covers vents and louvered windows. Each bungalow is treated in turn according to its size. During treatment there must be no people, pets or plants inside.
7. Ventilate. Rooms are opened to the breeze for the time the team specifies, until there is no ozone smell, before housekeeping goes in to make up the room.
8. A final check before reopening. We check the odor and the surfaces again before the first group checks in, and advise on humidity control during the season.

Ozone safety: No people, pets or plants may be inside during ozone treatment, and rooms must be fully ventilated before anyone re-enters. If guests are staying in other bungalows, the team chooses bungalows that are farther away, seals the vents facing each other and times the work so guests are not disturbed. Open-air spaces such as the pavilion over the water are not ozone-treated.

Caring for the Garden, Canals and Open Spaces in a Nature-Friendly Way

Pavilions and open areas. These do not need ozone treatment because the wind blows through them all the time. Scrub the floors and tables, wipe high-touch points with disinfectant only where needed, and wash and sun-dry the seat cushions or replace their fillings.

Orchard canals. Remove rubbish and branches that floated in with the flood. Do not pour disinfectant into the canals. If the water smells rotten or many fish have died, ask the local fisheries or agriculture office for advice on managing the water.

Rowing boats and life jackets. Rinse them with clean water, dry them thoroughly in the sun, wipe only the surfaces guests touch with disinfectant, and check that every life jacket is still in safe condition.

Vegetable beds and trees. Let the soil dry naturally, prune rotten branches, and never spray disinfectant on plants that will be used in guests' meals.

Mosquitoes. Mosquitoes multiply very quickly in orchard areas after the water goes down. Turn over containers that collect water, and if needed, talk to our mosquito spraying service about a plan that suits a property with canals and ponds.

Owner's Checklist Before the Team Arrives

• Photograph the damage in each bungalow, for relief applications or insurance claims.
• Prepare a site map and a list of booking dates, so the team can decide which bungalows must be ready first.
• Sort out the mattresses, pillows and cushions that need replacing, and arrange for new ones to arrive after the ozone treatment date.
• Wash all sheets and towels in hot water, dry them in strong sun, and keep them outside the linen room until the linen room has been treated.
• Have an electrician check the wiring and sockets in the flooded bungalows.
• Move potted plants, rubber decorations and electronics out of the rooms.
• Prepare a message for guests who have already booked, explaining honestly that the property is recovering from the flood and how it is being cared for.

Ongoing Care Throughout the Season

Garden accommodation needs constant humidity control. Open empty rooms to the breeze every day, stand mattresses up to air between guests, and wipe door handles, taps and remote controls with disinfectant spray after every check-out. Store linen in cabinets with ventilation, and keep an eye on bamboo joints, the undersides of bed platforms and bathroom corners.

If guests mention a musty smell or staff see new black spots, contact the team early for a re-assessment. Telling guests openly how the property was restored after the flood usually builds more confidence than saying nothing.

Some owners find it helpful to give housekeeping a simple daily card for each bungalow: windows opened, mattress aired, bathroom corners checked, any smell noted. It takes only a minute per room and catches problems while they are still small and cheap to fix.

Talking to Guests: Turning Recovery into Trust

Many owners worry that mentioning the flood will scare guests away. In practice, eco-travelers in particular tend to respond well to honesty. A short, friendly message before arrival works best: the orchard was affected by the October floods, the bungalows have been cleaned, disinfected and ozone-treated, mattresses that were in the water have been replaced, and the canals and garden were protected throughout. If something in the garden still looks a little bare, guests will understand why.

On arrival, a small note in each room explaining that ozone treatment leaves no residue once rooms are ventilated can also answer questions before they are asked. Some owners invite curious guests to see the before-and-after photos. Handled this way, the flood becomes part of the story of a place that cares, rather than something to hide.

An Example Reopening Timeline for a Six-Bungalow Homestay

Every property is different, and the team confirms real timings only after the survey, but an example helps owners picture how the work can fit around bookings. Imagine a homestay like Khun Nok's, with three flooded bungalows and three that are only damp.

• First days after the water recedes: soaked mattresses are taken out, mud is shoveled from the flooded bungalows and disposed of away from the canals, and every door and window is opened during dry hours. All linen goes through hot washing and sun-drying.
• Survey day: the team inspects every building, notes which bungalows are needed first for upcoming bookings, and checks how dry the floors and walls are.
• First treatment day: the three damp-only bungalows and the linen room are fogged and ozone-treated, because they can be ready soonest. Once ventilated, clean linen is moved back into the treated linen room.
• Second treatment day: after the flooded bungalows have had time to dry, they are fogged, sealed and ozone-treated one by one, then ventilated.
• Before the first check-in: new mattresses arrive, rooms are made up, and the team does a final odor check. The pavilion cushions are back from washing, and the boats have been rinsed and dried.

Planning this way means the first guests of the season can be welcomed in the bungalows that were ready earliest, while the more heavily affected ones are finished without pressure.

Common Mistakes Owners Make After a Flood

• Reopening the flooded bungalows first because they have the best view. They are usually the slowest to dry. Start guests in the rooms that are truly ready.
• Keeping mattresses that "seem dry." A dry surface does not mean a clean core. One complaint about a smelly bed can cost far more than a new mattress.
• Treating rooms but not the linen store. Fresh rooms with musty sheets still lead to musty reviews.
• Using strong chemicals near the water. It undermines the very reason guests chose an eco-stay, and it can harm the fish and plants that make the orchard special.

Before and After: An Orchard Homestay After the Water Recedes

What the Owner Said

"My biggest fear was that we'd have to use so many chemicals that the garden would suffer. The team explained that they would only fog inside the rooms, never into the canals, and then ozone-treat each closed room, which leaves nothing behind once it's aired out. They did the linen room too. The rooms smell so much fresher now, and we're ready for our first guests of the season."

Frequently Asked Questions

1. Will the disinfection affect the fish in the canals or the trees?
The team fogs only inside guest rooms, bathrooms and the linen room, closes the canal-side windows during fogging, and never sprays into canals, vegetable beds or shrubs.

2. Does ozone leave anything behind in the room?
Ozone breaks down back into oxygen once the room is ventilated for the time the team specifies, so it leaves no residue. During treatment, however, there must be no people, pets or plants inside.

3. Our bamboo bungalows have lots of vents. Will ozone treatment work?
Yes, when vents and louvered windows are temporarily sealed with plastic and each bungalow is treated in turn. Pavilions and open-air areas are cleaned and spot-disinfected instead.

4. Does a wet thatched roof need replacing?
That depends on its condition. If the thatch stayed wet long enough to start rotting or smelling, ask a craftsman to assess it. Disinfection and ozone reduce germs and odor, but they cannot make deteriorated material strong again.

5. Some bungalows have guests staying. Can you treat the others?
Yes. The team chooses bungalows farther from occupied ones, seals the facing vents and schedules the work so guests can rest undisturbed.

6. Should we tell guests who have already booked that the property was flooded?
Telling them honestly, along with how the property has been restored, usually builds more confidence and helps prevent negative reviews caused by mismatched expectations.

7. What about mattresses on bed platforms that were not in the water?
If they were not soaked but smell musty from humidity, sun-airing, ozone treatment of the room and dust mite removal can help. Mattresses that sat in floodwater should be replaced.
