A true story from a beach resort in Trat, Thailand
A 64-Room Beach Resort Watched Its Review Score Fall From 9.1 to 7.4 Because One Word Appeared 61 Times
When one word appears sixty-one times, and a 1.7-point drop becomes a season of rooms that will not sell
A 64-room beach resort in Trat watched its online booking score fall from 9.1 to 7.4 over fourteen months. When the team finally read every review, the word mosquito appeared 61 times. Here is the real cost, and how the AIROFOG AT35 thermal fogger brought the score back within a single season.
Pimjai, 41, is general manager of a 64-room beach resort in Laem Ngop district, Trat. Eight years open, with shaded gardens, a beachfront pool and regulars who return every year.
What began to worry her was the review score. It had sat at 9.1 for years, then slid steadily to 7.4 within fourteen months, while the resort changed nothing at all — not the pricing, not the service, not the team.
One night she sat down and read every review from those fourteen months, counting the words that recurred. The result needed no interpretation. Mosquito and related words appeared 61 times — far more often than food, price or staff.
Sixty-one reviews that told the team everything they needed
Pimjai separated out the mosquito reviews and read them again, to see the contexts. What emerged was a very clear pattern, and better information than any survey the resort had ever run.
Most mentions clustered around three times and three places. Dinner at the poolside restaurant, where guests said they ate quickly and went back to their rooms. Early evening on the room balconies, which is the resort's principal selling point, advertised for watching the sunset. And overnight in the ground-floor rooms.
What hurt Pimjai most were the many reviews that gave full marks for cleanliness and service, then wrote that it was such a shame to have to deduct points because of mosquitoes. Guests liked everything but one thing, and that one thing pulled the overall score down.
She also realised that the balconies — the resort's largest design investment — were effectively unused after six in the evening. The resort was paying to build and maintain them while guests could use them for only half the day.
What they found walking the property at six in the evening
Pimjai invited the district health officers to survey the property with the resort's maintenance team, choosing six in the evening rather than daytime. It was the first time the team had seen the real picture.
The first finding was the planting around the poolside restaurant: large-leaved ornamentals chosen for beautiful shade, which hold high humidity and were the densest mosquito harbourage on the property — a few metres from the dining tables.
Second were the hundreds of plant saucers throughout the resort, kept permanently full because the gardening team waters daily. Third were the gutters on the guest room buildings, blocked with leaf litter. Fourth were three decorative lotus ponds with no water circulation.
The last finding, which nobody had considered, was the area behind the kitchen and around the bins: standing wash-down water and food waste, attracting both mosquitoes and flies — and sitting exactly upwind of one of the guest room buildings.
What 1.7 points translates to in money
Pimjai did the arithmetic properly. Comparing booking data across the period the score fell, average occupancy had dropped from 74 percent to 58 percent — roughly 10 more empty rooms a night.
Multiplied by average room rate across a year, the lost revenue came to roughly 8,700,000 baht, before counting the food and beverage revenue lost with the missing guests, and before counting the in-house guests who would not sit down to dinner at the resort's own restaurant.
She also found the repeat guest share had fallen from 31 percent to 18 percent, which is the more alarming figure, because repeat guests are the most profitable segment and carry the lowest acquisition cost.
And there was an invisible but real cost: staff time spent answering reviews and apologising at the desk, which wears down a team that knows it is doing good work and being marked down for something outside its control.
What the resort changed before the next season
Pimjai proposed a three-part plan to the owner. First, eliminate every breeding site found: change to a watering system that does not need saucers, clean the gutters monthly, install circulation pumps in the lotus ponds and stock larvivorous fish, and regrade the ground behind the kitchen so it drains.
Second, adjust the landscaping at the problem points: thin the large-leaved ornamentals around the restaurant and remove the shrubs closest to the dining tables, which sharply reduces harbourage without losing the look.
Third — the change that actually shifted the outcome — buy thermal foggers for the resort and set a daily schedule between three and four in the afternoon, concentrating on the restaurant gardens, the ground-floor balcony line, the lotus ponds and the area behind the kitchen.
The resort chose two AIROFOG AT35 units, because the gardening team can operate them, the stainless body resists the salt air that destroys every piece of equipment at a beach resort, and service and genuine parts are available inside Thailand.
What it actually costs
Your review score is your room rate and your occupancy
A fall from 9.1 to 7.4 took occupancy from 74 percent to 58 percent, roughly 8,700,000 baht a year. In hospitality a review score is not decoration. It determines where you appear in search results.
Losing repeat guests, the most profitable segment
The repeat guest share fell from 31 percent to 18 percent. Repeat guests carry the lowest acquisition cost and generally spend more on property, so losing them hits profit harder than the room numbers suggest.
Paying for spaces guests cannot use
Balconies and the poolside restaurant are the resort's largest investments and its main selling points, yet guests were not using them after six in the evening. The resort was paying to build and maintain them for half a day's use.
Team morale
Staff who do good work but spend their time apologising for something outside their control lose heart quickly. In a service business where good people are already hard to find, losing them over a solvable problem is a loss that should never happen.
Why the usual fixes do not work
Putting mosquito coils on the dining tables and balconies
Smoke reaches a few metres and is carried away almost instantly by the sea breeze. The smell interferes with the meal, and a coil on every table tells guests directly that this place has a mosquito problem — a message no resort should send.
Leaving repellent spray in the rooms
Well-intentioned but it sends the wrong signal. A guest who finds repellent in the room understands immediately that there is a problem, and in practice most never apply it, so the problem and the reviews continue unchanged.
Electric insect traps around the pool and restaurant
These work within a very limited radius and draw insects toward a light source. In a large outdoor area already lit throughout, their effect is negligible — and the noise and light interfere with the atmosphere the resort is trying to create.
Contracted spraying once a month
The contractor comes on his own schedule, usually mid-day when mosquitoes are sheltering. Monthly is far too infrequent against a species that goes from egg to adult in seven to ten days, and the resort has no control over the timing at all.
Replying politely to every review and apologising
Necessary and worth doing well, but replying does not fix what caused the review. Without addressing the source, new reviews say the same thing every week — and dozens of identical apologies show readers a chronic problem.
A resort needs to fog daily, before guests use the outdoor spaces
Once the reviews showed the problem occurring at three specific times in three specific places, the requirement became clear: reduce mosquito numbers in those areas before guests go out into them, which means before evening.
A thermal fogger is the right tool, because the fog drifts into the large-leaved planting around the restaurant, beneath the ground-floor balconies, around the lotus ponds and into the service area behind the kitchen — the harbourage that coils and traps can never reach.
The right window is three to four in the afternoon, two to three hours before guests come out. It is a safe interval, and the sea breeze is starting to settle, so the fog holds over the area longer.
The machine must belong to the resort, because it needs running daily through the rainy season, and it has to withstand the salt air that corrodes everything at a beachfront property. That is why they chose the AIROFOG AT35, with its 100 percent stainless steel body.
10 reasons the AIROFOG AT35 thermal fogger solves it
1. A 100 percent stainless steel body that resists coastal salt air
Salt air destroys equipment at a beachfront resort remarkably quickly. Coated-metal and plastic-bodied machines commonly fail within a year or two in those conditions. Full stainless construction is a necessity rather than an upgrade for a coastal business.
2. Fog reaches large-leaved planting and beneath ground-floor balconies
Mosquitoes on a resort rest in the large-leaved shade planting, beneath ground-floor balconies, around the lotus ponds and in still corners behind buildings. The AIROFOG AT35 produces a fog that genuinely drifts into these places without damaging plants or leaving residue on paving.
3. Finished before guests come out, so it never intrudes on the experience
Owning the machine lets the resort set its own window between three and four in the afternoon, when most guests are in their rooms or on the beach, finishing well before dinner service — so there is no smell and no disruption to the atmosphere.
4. The resort's own gardening team can operate it
Every resort already has gardening and maintenance staff. The AT35 is a shoulder-carried machine simple enough that two or three of them can be trained to take responsibility, so fogging becomes a daily routine like watering, at no additional labour cost.
5. Covers the whole property in well under an hour
A 64-room resort with gardens, pool, restaurant and service areas takes roughly 45 to 60 minutes with the AT35 — short enough to genuinely do every day without disrupting the gardening team's other work.
6. Runs both water-based and oil-based formulations
A resort has areas near the pool, near the kitchen and near fish ponds that call for different chemistry. Accepting both formulation types lets you match the product to each area and rotate products through the year to slow resistance.
7. Light enough for narrow paths and steps across the property
Beach resorts have gravel paths, steps down to the sand and garden areas no trolley can enter. The AT35 is light enough for one person to carry throughout, including the beach tree line and the boundary shrubbery.
8. Certified to German and British standards
For hotels audited under accommodation standards or SHA certification, and needing to explain hygiene measures to guests and tour operators, internationally certified equipment is something you can present as evidence.
9. Compliant with Thai government standard equipment specifications
For state-owned resorts, official guest houses and state enterprise accommodation procuring under public procurement regulations, conformity with the standard equipment schedule makes budgeting and acceptance inspection straightforward.
10. A Thai service centre with genuine parts and 10-plus years of technician experience
High season is precisely when a resort cannot stop fogging, because the property is full and reviews are being written daily. Domestic service and genuine parts mean fast resolution rather than a month waiting on overseas shipment at the most important time of the year.
Before the thermal fogger
- Review score down from 9.1 to 7.4 over fourteen months
- The word mosquito appearing 61 times in reviews, more than any other
- Occupancy down from 74 percent to 58 percent
- Roughly 8,700,000 baht a year in lost revenue
- Repeat guests down from 31 percent to 18 percent
- Balconies and the poolside restaurant barely used after six in the evening
After the thermal fogger
- Review score back to 8.9 within one season
- The word mosquito appearing just 4 times over the same length of period
- Occupancy back to 76 percent
- Dinner food and beverage revenue up 64 percent
- Repeat guests back up to 29 percent
- Balconies and the poolside restaurant full every evening
The three-step process
1. Read the reviews and count the words before guessing at causes
The cheapest and fastest way to find a hotel's real problem is to read twelve to eighteen months of reviews and count the recurring words, noting the context, time and place each is mentioned. That data points precisely at what to fix.
2. Survey the property at six in the evening and eliminate the breeding sites
Walk it with the gardening and maintenance teams when mosquitoes are actually out. Mark every point holding water: plant saucers, gutters, lotus ponds, air-conditioner drip trays, the area behind the kitchen and garden hollows. Fix them all before you start fogging, because fogging alone without source reduction means fogging forever.
3. Fog daily between three and four, and measure the result in reviews
Concentrate on the restaurant gardens, the ground-floor balcony line, the lotus ponds and behind the kitchen. Fog daily for the first two weeks, then daily through the rainy season and alternate days in the dry. Measure with the monthly count of mosquito mentions in reviews — the indicator closest to the business.

The breeding sites hotels and resorts most often miss
Plant saucers are the most common finding at every resort, because attractive properties keep hundreds of pots and the gardening team waters daily, leaving the saucers permanently full. The best fix is switching to a system that drains without saucers, or drilling drainage holes in every one.
Air-conditioner condensate trays, especially on externally mounted units, hold water constantly through the hot season and are almost never inspected. Make them a line item on the maintenance team's monthly checklist.
Lotus ponds and decorative water features whose pumps have failed, or are switched off to save electricity, become large bodies of still water in the middle of the property overnight. Either repair the circulation or, if it must be off, drain it dry or stock larvivorous fish.
The area behind the kitchen and around the bins attracts both mosquitoes and flies, combining standing wash-down water with food waste. Regrade the ground so it drains, use lidded bins, and include the area in every fogging pass.
Why reviews are the most business-relevant metric a hotel has
The hardest thing to measure in hospitality is how guests feel — and online reviews are that data, given freely and bluntly, with a direct effect on revenue, because they are what the next booker reads before deciding.
The way to use reviews as a metric is to count how often key words appear each month — mosquito, noisy, clean — and graph that against the measures you have taken. It shows immediately which measures actually worked.
There is a second benefit: the team sees the result of their own work as a number. When the gardening team learns their daily fogging took mosquito mentions from sixty-one to four, that job stops being a chore and becomes something they take pride in.
And over time the same data explains to the owner or the board what each investment returned, which makes approving next year's budget substantially easier.
Frequently asked questions
Is fogging safe at a resort with guests staying?
Yes, with the right procedure: fog when guests are not using the outdoor areas, around three to four in the afternoon; notify guests near the area; cover food and any containers that need it; and allow roughly 30 to 60 minutes before reopening the space.
Will there be a lingering smell that bothers guests?
If you fog two to three hours before guests come out and choose an appropriate product, it dissipates well before they use the space. That is why most resorts choose an afternoon window, when guests are in their rooms or on the beach.
How many machines does a resort of my size need?
Up to about 40 rooms with gardens, one machine is enough. For 50 to 100 rooms, two, so a full pass finishes within an hour and there is a spare. Resorts with widely separated zones should consider three.
How often should we fog?
Daily for the first two weeks to break the cycle, then daily or on alternate days through the rainy season and two to three times a week in the dry. Let the monthly count of mosquito mentions in your reviews drive the decision.
Can the gardening team operate it?
Yes. Designate two or three responsible operators and train them fully on mixing, protective equipment and cleaning the machine after every use — which matters especially at a beach resort, because salt air accelerates wear on an unwashed machine.
Will the chemical harm the garden plants or pond fish?
Not when using an insecticide registered for the purpose at label rates. For fish ponds, avoid directing the fog straight onto the water surface and choose an appropriate product. Ask your supplier about products suited to areas with aquatic life.
Should we fog the beach as well?
Treat the shrubbery and tree line along the beach, which is where mosquitoes rest, but there is no need to fog open sand where the wind blows constantly and mosquitoes do not settle. Focusing on the right points saves chemical and produces better results.
What if the machine fails in high season?
AIROFOG maintains a service centre and genuine parts in Thailand with technicians of more than 10 years' experience, so issues are resolved fast. Year-round resorts are advised to keep at least one spare machine, because a full house is exactly when fogging cannot stop.
One word in a review, against eight million baht a year
The clearest lesson here is that the answer to a business problem is often sitting in data customers have already given you for free, and you simply have not sat down and read it properly.
Pimjai found in one night the answer to a question that had stood for fourteen months, and solved it over one season, for less than the revenue she recovered in the first month alone.
In a business that sells an experience, a small problem guests feel every evening always ends up as a number in the financial statements — and fixing the source is among the fastest-returning investments a hotel can make.
